ROUND AND ROUND

Students determine how speed is measured. In this physics instructional activity, students design an experiment to find out if the robot's drive wheel size affects its speed. They collect data and discuss results.

Math and science come together in this cross-curricular astronomy lesson plan on planetary motion. Starting off with a hands-on activity that engages the class in exploring the geometry of circles and ellipses, this lesson plan then...

Students explore natural water sources. In this water sources activity, students investigate water reservoirs. Students work with sponges to simulate a community's natural water consumption. Students discover how water returns to the...

Students discuss and interpret background knowledge on poster copy given on the water cycle. Students complete the included activity sheets using the poster as a reference in small groups. Students identify and name where water can be...

In this centripetal force worksheet, students investigate the relationship between an object's orbiting speed and the centripetal force acting upon the object. Students us two rubber stoppers, some twine and a tube to study the...

In this wheels and axles activity, students read a 1 page article, make a list of how many objects they can find or think if that uses a wheel or axle and then design their own machine.

Round and round in circles it goes! A hands-on activity has learners recreate a model of a convection cell. They watch as the difference in density of their materials creates a current.

The wheel goes round and round, round and round. Learners observe four demonstrations that use a spinning bicycle wheel. After the demonstrations, the class discusses the forces involved with a gyroscope. Discussion questions tie inertia...

Students build a device that captures and carries a pet rat safely back to its cage with out "harming" the rat or themselves. They build and experiment with wind-up or battery operated rat cat toys after predicting the outcome of their...

When you look out to the horizon, the earth looks flat, so how do we know it's round? We learn that gravity pulls planets toward the center and shapes them into the spheres that dominate space. This is a great clip that fully explains...
