In this physics activity, learners will explore buoyancy.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

In this physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this Energy and Environment activity (page 9 of the PDF), learners calculate the mass of a piece of gum, compare it to the mass of the gum's packaging, and then create a bar graph of the results.

In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).

In this activity, learners create a kind of balance device using a wire coat hanger, some string, and paper cups.
