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.
