New Inclined Plane Gizmo

Anybody who has carried furniture into a moving van, wheeled a chair up an access ramp, driven on a switch-back road or skied down a bunny-slope understands the usefulness of inclined planes. Inclined planes can reduce the effort needed to lift an object up or slow the descent of a falling object.

Both aspects of inclined planes can be investigated in our new Inclined Plane - Simple Machine Gizmo. Observe the forces acting on a brick as it slides down a ramp, then measure the force required to push the brick back up. This Gizmo can be used at a variety of levels, from middle-school to AP Physics. (For a real challenge, check out the proof at the end of the Exploration Guide - feel free to write to customer support if you need a hint!)

Our library now boasts three Gizmos that can be used to study simple machines (the other two are Pulley Lab and Torque and Moment of Inertia), and more are planned for the future. Enjoy!

Great science fair Gizmos updated

As science fair season is rolling around and students are hunting for topics, we have recently updated several Gizmos your students might consider using for a project. These are also among our most exciting and "gamelike" Gizmos to try.

In Reverse the Field, students can see how well they adapt to reversing the direction that the cursor moves when they move the mouse. Students can measure their reaction times in Sight vs. Sound Reflexes, and test their time-estimation skills in Time Estimation and Real-Time Histogram. The new Exploration Guides for these Gizmos highlight data-analysis skills and are full of tips for creating excellent science fair projects as well.

Many people know the famous story of Archimedes running naked through the streets of Syracuse yelling "Eureka!" But few can explain what Archimedes' Principle actually says. To find out, check out our new Gizmo Archimedes Principle, which mimics a popular lab of placing weights into a rectangular boat and measuring how far it sinks. By combining lab observations with the precise data available in the Gizmo, the beautiful symmetries of Archimedes' Principle will be revealed.

Mercury Transit

Every so often Mercury will be between the Earth and the Sun such that it is visible from the Earth. That is happening today and won't happen again until May 9, 2016!

For more information you can visit the Wikipedia article that discusses the transit.
