In this activity (Lesson 1), learners work in groups to create tide simulations.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.

In this three part activity, learners explore and experiment with shadows to learn about the Sun's relative motion in the sky.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation about the different causes of glacial melt.

In this activity, learners will make a model rocket to test the phrase "what goes up must come down." Learners will power their rockets with air pressure, and soon discover the effects of air resistan

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

In this activity about magnetism (page seven of the pdf), learners experiment with magnets to better understand how magnetic fields work.

In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.
