### Lesson Material Updates

Gizmos are a great way to provide conceptual understanding of complex mathematical concepts. Check out these interactive mathematics Gizmos that just received updated Lesson Materials.

• Integers, Opposites, and Absolute Values

• Circles

• Least-Squares Best Fit Lines

• General Form of a Rational Function

In the Addition of Polynomials Gizmo, students use tiles to model and add two polynomials of the form ax^{2} + bx + c. The Gizmo provides feedback for incorrect steps, and the randomized problem generator allows for unlimited practice to support mastery.

Also, check out the User Lesson Materials from members of the Gizmos community. Kathleen Kaplan submitted a lesson plan for the Addition of Polynomials Gizmo that includes a real-world problem involving the distance between jets, where students will need to subtract polynomials.

### Celebrate Fall with New Lesson Materials

Celebrate the fall season with new Lesson Materials! Six of our math Gizmos have updated materials just in time for a little fall fun.

Use the Elapsed Time Gizmo, along with its newly updated Lesson Materials, to give students an application of “borrowing” when subtracting, in a real context. (Perhaps you and your students want to calculate elapsed times after a class apple-bobbing contest?)

If Geometry is more your speed, try the Chords and Arcs Gizmo. The updated materials guide students as they explore how a central angle in a circle is related to the arc and its intercepts (and if the visual reminds you a bit of a piece of pumpkin pie, well, so be it). Students can also explore the relationship between chords and their distance from the circle's center.

Other Gizmos with updated Lesson Materials include:

Wishing you all a happy and safe fall season!

### Expert Corner: Changes to Roller Coaster Physics

*Kurt Rosenkrantz is a science curriculum writer and Gizmo designer for
ExploreLearning. Kurt holds a Master of Science in Geology from the
University of Cincinnati, and a bachelor's degree in Earth Science from
Harvard. He taught high school and middle school science for eight years
before joining ExploreLearning in 2005.*

A while ago, a teacher named Joshua Buchman suggested a way to improve our popular Roller Coaster Physics Gizmo. In the Gizmo, a toy car rolls down a track, over several hills, and into an egg. The egg will either crack or not.

In the original Gizmo, the egg would crack if the momentum of the car was over a certain threshold value. Mr. Buchman pointed out that it was more likely that the kinetic energy of the car, rather than its momentum, would be the critical factor. He argued that the car would need to travel a certain distance into the egg, overcoming the resisting force of the eggshell, for the egg to crack. In other words, the car would have to do a certain amount of work to crack the egg, and the work it could do depended on its kinetic energy.This argument made sense to us, but we wanted to check that it was true in practice before changing the Gizmo, which was designed with the help of real-world experiments that took place in the EL offices a decade ago. To investigate, I bought toy cars, a track, and several dozen eggs. I set up the track at a steep angle and went to work.

Right away I realized that I needed to establish a consistent definition of “egg breaking.” It turns out that a very tiny impact can cause a small fracture in the egg, and that the fracture grows bigger and bigger as the force of the impact increases. Eventually I decided that the most consistent criteria I could use was “eggshell breaks completely into two halves.” So, any fracture that did not go all the way around the egg was considered a negative result.

After several very messy sets of experiments using cars of different masses, I plugged the data into a spreadsheet. Sure enough, the minimum kinetic energy required to break the egg was much more consistent than the minimum momentum required to break the egg. With experimental results supporting the scientific argument, we decided to make the change. In the updated Gizmo, the car now needs to have a minimum kinetic energy of 0.25 J to break the egg. We have adjusted all of our lesson materials and assessment questions to reflect this new result.

We hope you enjoy the new-and-improved Roller Coaster Physics Gizmo, and thanks again to Mr. Buchman for bringing this to our attention!

### Growing Geometry Gizmo Lesson Materials

Geometry is the branch of mathematics concerned with points, lines, angles, shapes, and solids. Without a true understanding of the properties and relationships of these figures, students are likely to struggle as they progress toward higher math courses. Gizmos are such a great fit when building students' understanding of geometry because they provide an interactive, inquiry-based experience that reinforces the conceptual understanding students need.

The ExploreLearning team is constantly working to keep your Gizmo resources updated, and we are pleased to share these math Gizmos have all new Lesson Materials.

Rotations, Reflections, and
Translations

Surface and Lateral Area of
Prisms and Cylinders

Surface and Lateral Area of
Pyramids and Cones

Parallel, Intersecting, and Skew
Lines

Constructing Parallel and
Perpendicular Lines

Circumference and Area of Circles

Constructing Congruent Segments and Angles

As always, our goal is real student understanding, beyond just formulas or memorization. For example, in the new Student Exploration Sheets with the Rotations, Reflections, and Translations Gizmo, we work to help students see that each type of transformation is really just a specific rule – a function, essentially – which can be applied to any figure, point by point, to create the transformed figure. In the Mathematical Background, found in the Teacher Guide, we expand on this “transformations as functions” idea, to help support teachers in how they might want to present this topic.

Reminder: Our updated Lesson Materials have 4 documents (Student Exploration Sheet, Answer Key, Teacher Guide, and Vocabulary Sheet), each available as a .doc or .pdf. (You'll need to be logged in to see all four documents.)

### 6 new sets of Lesson Materials - the math Gizmo update continues!

Even with summer almost here at ExploreLearning headquarters, the Math Lesson Materials team is still hard at work! We've just published 6 new sets of Lesson Materials, accompanying these geometry Gizmos:

Segment and Angle Bisectors (the Gizmo formerly known as "Bisectors in Triangles")

As always, our goal here is real student understanding, beyond just formulas or memorization, with an inquiry-based approach. (A good example is the Distance Formula Gizmo, at the top of the list above. Our goal in this lesson is to help students see that the distance formula is not some crazy new formula they need to learn - it's really just an application of the Pythagorean Theorem.)

This release brings us up to 69 high-school- and middle-school-level math Gizmos with updated Lesson Materials. Reminder: Our updated Lesson Materials have 4 documents (Student Exploration Sheet, Answer Key, Teacher Guide, and Vocabulary Sheet), each available as a .doc or .pdf. You'll need to be logged in to see all four document.

### Math Gizmos - Lesson Materials - 3 new sets released

Alert, Gizmo mavens! More new Lesson Materials have been released for your viewing/learning pleasure!

Perimeters and Areas of Similar Figures - Suppose you took a figure and doubled all of its side lengths. How would its perimeter change? What about its area? Why?

Concurrent Lines, Medians, and Altitudes - If you cut a triangle out of something sturdy, like cardboard, where is its balancing point? How would you find it?

Introduction to Exponential Functions (formerly known as "Exponential Growth and Decay - Activity B") - What's an exponential function all about? How do the y-values behave? What do all exponential functions have in common?

As always, our goal here is real student understanding, beyond just formulas or memorization.

Reminder: Our updated Lesson Materials have 4 documents (Student Exploration Sheet, Answer Key, Teacher Guide, and Vocabulary Sheet), each available as a .doc or .pdf. (You'll need to be logged in to see all four documents.)

At this point, 63 high-school- and middle-school-level math Gizmos have now received the updated Lesson Materials "treatment." We hope you and your students enjoy these latest new ones!If you'd like to try these Gizmos, or any of the others in our library, sign up for a free trial today!

### Math Gizmos - new Lesson Materials released today

Another new batch of math Lesson Materials is hot out of the oven! We've cooked up some geometry for you and your students:Pythagorean Theorem with a Geoboard

Pythagorean Theorem - Activity B

In these lessons, we work to build students' understanding of these topics, beyond just the formulas or definitions. How can you use a geoboard to show that, in right triangles, *a*^{2} + *b*^{2} = *c*^{2}? Also, we've often heard that similar polygons have the same shape but not necessarily the same size. What exactly does that mean in terms of side lengths and angle measures?

As always, our updated Lesson Materials have 4 documents (Student Exploration Sheet, Answer Key, Teacher Guide, and Vocabulary Sheet), each available as a .doc or .pdf. (You'll need to be logged in to see all four documents.)

So we are now up to 60 high-school- and middle-school-level math Gizmos with updated Lesson Materials.If you'd like to try these Gizmos, or any of the others in our library, sign up for a free trial today!

### New Lesson Materials for 3 more math Gizmos

Another new batch of math Lesson Materials went live today! This batch includes some nice variety - one geometry Gizmo, one statistics/ratio/proportions Gizmo, and one exponentials Gizmo.

Investigating Angle Theorems - Activity B

Exponential Functions - Activity B

These 3 Gizmos take our usual inquiry-based approach to teaching math. We strive to ask rather than tell, with students using the Gizmo as an exploratory "what if" tool to build their understanding of the topic at hand. In particular, "Estimating Population Size" is a favorite of mine. It uses the "capture-recapture" method of estimating the fish population of a pond, leading to some really good mathematical thinking. Check it out if you haven't already!

As always, our updated Lesson Materials have 4 documents (Student Exploration Sheet, Answer Key, Teacher Guide, and Vocabulary Sheet), each available as a .doc or .pdf. (You'll need to be logged in to see all four documents.)

This brings us to 57 high-school- and middle-school-level math Gizmos with updated Lesson Materials - with lots more on the way!

### New Lesson Materials - 3D geometry, with a splash of statistics

A new batch of math Lesson Materials went live today! This batch features a unique blend of flavors - mostly geometry (volume of three-dimensional figures), but spiced with a dash of statistics (scatter plots and making estimates):

Prisms and Cylinders - Activity A

Pyramids and Cones - Activity B

How do you find the volume of a prism (or its close cousin, a cylinder)? How much "space" does a pyramid take up compared with a prism? (Or, a cone compared with a cylinder?)

Also, what's a scatter plot, and how can you use them to spot trends in data, and then make reasonable estimates or predictions?

These 3 Gizmos (and the newly-published Lesson Materials) are designed to address those topics.

As always, our updated Lesson Materials have 4 documents (Student Exploration Sheet, Answer Key, Teacher Guide, and Vocabulary Sheet), each available as a .doc or .pdf. (You'll need to be logged in to see all four documents.)

We're now up to 54 high-school- and middle-school-level math Gizmos with updated Lesson Materials, with more to come.If you'd like to try these Gizmos, or any of the others in our library, you can sign up for a free trial today!

### New Lesson Materials - triangles and parallelograms, oh my!

We're still cranking away in the ExploreLearning Lesson Material factory! Today, we have released 3 new sets of Lesson Materials on the site. This batch explores more geometry topics:

What defines an isosceles triangle? What conditions guarantee that a quadrilateral is a parallelogram, or that a parallelogram is a rhombus... or rectangle... or square? These Gizmos - along with the new Lesson Materials - are designed to help kids explore questions like that, in an interactive way.

One quick note about the Student Exploration Sheet (SE) - the SE may be longer than most student "worksheets" that you're accustomed to. We do NOT expect teachers to assign the whole SE! (At least, not all at once.) The lesson that we generally recommend is this: page 1 of the SE (Prior Knowledge Questions + Gizmo Warm-up) plus ONE of the activities in the SE. That would total 2-3 pages. (Of course, feel free to revise our SE in any way you'd like - that's why we publish them in .doc form.)

In general, we write multiple activities within one SE to make it easier for teachers to differentiate instruction. In other words, more activities = more options.

Overall, this bring us up to 51 high-school- and middle-school-level math Gizmos with updated Lesson Materials, with plenty more to come.

### Australian correlations, and refined Gizmos browsing

Gizmos are now correlated to the Australian Curriculum! You can now search for math and science Gizmos for that align with Australian standards from grades 3-10.

As part of this expansion of our correlations, we have overhauled the Browse Gizmos page to make it a little easier for educators to delve into the library of more than 450 Gizmos.

Now when you first open the Browse Gizmos page, you can easily choose to browse by academic standard, by grade and topic, or by textbook correlation.

If you select to browse by academic standard, the site will do its best to display standards from your country. But if it can't correctly specify your country (or if you feel like browsing standards of another country), you can click on the "Switch Country" button available in that section. We currently list standards for the United States, Canada, and Australia, and we will be working on adding more countries as Gizmos continue to become more popular around the world.

### 3 sets of new Lesson Materials - math Gizmos

We've released 3 more new sets of Lesson Materials to the wild:

Biconditional Statements Gizmo

Dividing Polynomials Using Synthetic Division Gizmo

The first two Gizmos are word-tile-based Gizmos that encourage students to think about logic, truth values, and definitions.

The third is a number-tile-based Gizmo that's designed to help algebra students see the connections between synthetic division and polynomial long division. (They're really the same thing, if you see them side-by-side.)

As always, logged-in teachers will have access to all 4 of our Lesson Material documents (Student Exploration sheet, Exploration Sheet Answer Key, Teacher Guide, and Vocabulary sheet), available either as a Word document or as a pdf.

The math content team is happy to report that we've published 3 new sets of Lesson Materials!

Using Algebraic Expressions Gizmo

Finding Factors with Area Models Gizmo

Isosceles and Equilateral Triangles Gizmo

As always, logged-in teachers will have access to all 4 of our Lesson Material documents (Student Exploration sheet, Exploration Sheet Answer Key, Teacher Guide, and Vocabulary sheet), available either as a Word document (for easy editing if you like) or as a pdf (smaller file size).

It's an assortment of topics in this batch - from writing algebraic expressions, to number sense (with prime numbers and factor trees), to triangles. We hope you'll find these useful, and will help you bring inquiry and real understanding to these topics for your students. (It's a fun challenge to walk students through these lessons with questions rather than just telling them what they need to know. Good questions + a Gizmo can be a powerful formula for understanding rather than memorizing. That's always what we're after.)

This brings us up to 32 math Gizmos with new Lesson Materials now, as part of our Math Update project! Lots of outlines and drafts are in progress, so stay tuned for more updated Lesson Materials to come.

### Two new science Gizmos

Have you ever wondered what happens to the food you eat? Most of us are pretty familiar with the path of the digestive system--mouth, esophagus, stomach, and so on. But what would happen if our digestive systems were designed differently? What if food went through the small intestine before the stomach? What would happen if the pancreas was attached to the large intestine? Do we really need a gallbladder?

The new *Digestive System* Gizmo allows students to arrange the organs and structures of the human digestive system in any way they like. By measuring how well different nutrients are digested and absorbed, students can discover for themselves the important role that each organ plays in the digestive process. Perhaps somebody can use this Gizmo to improve the design of our own digestive system!

An important skill in all areas of science and math is the ability to convert a measurement or value from one unit to another. The *Unit Conversions *Gizmo allows students to answer questions such as "What is the height of Mount Everest in kilometers?" or "How fast is sprinter Usain Bolt in miles per hour?" With 55 preset problems (and 12 additional randomized questions) to choose from, students will get plenty of practice converting distance, time, speed, mass, volume, and density units. This is a great review before end-of-year tests as well as an excellent way to start off next Fall.

We hope you enjoy the new Gizmos and please let us know what you think!

### New Lesson Materials for 3 math Gizmos!

We've published new Lesson Materials for 3 math Gizmos:

Simplifying Radical Expressions - Activity A

Simplifying Trigonometric Expressions

Sum and Difference Identities for Sine and Cosine

These 3 Gizmos help students with some fairly advanced topics. Unlike most Gizmos, these are very procedure-focused rather than exploratory. We ask students to work through the steps of a problem, one-by-one, with careful feedback given for any incorrect choices. Each Gizmo will always start with the same 2 problems (which are addressed specifically in the Lesson Materials), and then are randomized after that, to allow for nearly unlimited practice.

As usual, each set of updated Lesson Materials includes 4 documents (Student Exploration sheet, SE Answer Key, Teacher Guide, and Vocabulary sheet), all of which are available as a .doc or a .pdf. (Note: You will need to be logged in to see all the documents.) These replace the older html Exploration Guides.

We're now up to 23 math Gizmos that have updated Lesson Materials (63 total, if you include the purple "elementary" math Gizmos which already had them). We also have plenty more "works in progress" going on in the background.

Enjoy! And stay tuned for more in the coming weeks and months.

### New Math Lesson Materials Published

We've just published 2 new sets of Lesson Materials for two of our most popular math Gizmos!

Polygon Angle Sum - Activity B

Quadratics in Polynomial Form - Activity A

As usual, each set of updated Lesson Materials includes 4 documents (Student Exploration sheet, SE Answer Key, Teacher Guide, and Vocabulary sheet), all of which are available as a .doc or a .pdf. (Note: You will need to be logged in to see all the documents.)

This brings us to 20 math Gizmos with updated Lesson Materials (well, 60 if you count the more modern "purple ones" that have never had anything but Lesson Materials). We still have a long way to go in this project, but there's plenty of progress happening "behind the scenes."

We hope these new Lesson Materials are a help to you and your students - lots of good explorations and thought-provoking questions here.

### Ring in the new year with new Gizmos

We have released two new science Gizmos to start the new year. Both Gizmos are appropriate for students in elementary school through high school and cover highly requested topics.

The first Gizmo is called Dichotomous Keys. In this Gizmo, students use dichotomous keys to identify a variety of plants and animals, including California albatrosses, Texas venomous snakes, and more. Students can then try creating their own dichotomous keys for organisms in the Gizmo or for organisms found where they live.

The second new Gizmo is called Measuring Volume. In this Gizmo, students can use a variety of containers and tools to measure the volumes of liquids and solids. Students can fill containers from a faucet, pour water from one container to another, add objects to containers, and measure the dimensions of objects with a ruler. An eyedropper is available to add or remove small amounts of water, and a magnifying glass can be used to get a closeup view of a meniscus. Students can test their skills using the "Practice" mode of the Gizmo.

We hope you enjoy using the new Gizmos and wish you a great beginning to the new year!

### Two new chemistry Gizmos

We have released two new chemistry lessons focused on the concept of chemical equilibrium:

The two lessons use the same Gizmo but focus on different topics. In the *Equilibrium and Concentration* lesson, students observe reversible reactions to gain an understanding of why chemical equilibrium occurs and how equilibrium constants are calculated. The follow-up lesson, *Equilibrium and Pressure*, discusses partial pressure, Dalton's law, and Le Chatelier's principle.

We hope you enjoy the new lessons as we continue to expand our chemistry coverage!

### New lesson materials published!

We've posted 3 sets of new Lesson Materials today! In addition, the Gizmos themselves (all 3 of these) were updated to gain some new problem types, so your students will be able to get more practice with more types of problems. Check them out:

Dividing Exponential Expressions

Multiplying Exponential Expressions

As usual, each set of updated Lesson Materials includes 4 documents (Student Exploration sheet, SE Answer Key, Teacher Guide, and Vocabulary sheet), all of which are available as a .doc or a .pdf. (Note: You will need to be logged in to see all the documents.)

This brings us to 18 math Gizmos with updated Lesson Materials. We have a long way to go on the math side, but we're hard at work on it!

Hope these new materials are a help - to teachers and students alike.

### New Titration Gizmo

Just in time for the new school year, we are pleased to announce a new chemistry Gizmo called Titration. In this Gizmo, students can measure the quantity of a solution of known concentration needed to neutralize an acid or base of unknown concentration, allowing the unknown concentration to be determined. A special "Worksheet" tab on the Gizmo gives students a hand in completing the calculation and allows them to check their work. In addition to titration, the Student Exploration sheet for the Gizmo covers several important topics such as pH calculation, titration curves, acid-base reactions, and the importance of choosing the correct indicator.

We will be working on several more chemistry Gizmos this year to expand our coverage of this subject. Enjoy the Gizmos and good luck with the start of the year!

### New Lesson Materials - 3 "Pathfinder" Math Gizmos

We're happy to announce that today we have published new Lesson Materials to go with 3 of our "Pathfinder" math Gizmos:

Solving Formulas for any Variable

These sorts of Gizmos ask students to solve problems, step-by-step, with feedback for any wrong answers along the way. They focus on algebraic procedures, but in a thoughtful way. The new Lesson Materials will help get students started, thinking about what they are doing, and then the Gizmo can take it from there, providing feedback for students.

By the way, we have also updated the Gizmos themselves. You'll find a deeper bank of problems to allow for more student practice.

Give them a try!

And, as they say, "more to come"!

### First new Gizmos of 2011

We are proud to announce the first new science Gizmos of 2011! They are *Ripple Tank* and *Electromagnetic Induction*.

In the Ripple Tank Gizmo, you can run a variety of experiments to demonstrate wave motion, diffraction, reflection, interference, and even refraction with several submerged obstacles. The wavelength and wave strength can be adjusted in each scenario. This Gizmo really complements our other wave Gizmos such as Longitudinal Waves, Refraction, Phased Array, and Doppler Shift.

Electromagnetic induction is the fundamental principle behind all generation of electricity and was one of the most important discoveries of 19th century physics. Students can explore this vitally important phenomenon with the Electromagnetic Induction Gizmo. The Gizmo allows students to move a magnet or a coil of wire to induce an electric current in the wire and light a light bulb. This Gizmo provides the perfect followup to our related Magnetic Induction Gizmo.

We hope you enjoy the new Gizmos!
