In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In two separate bags, learners mix water with Epsom salts and detergent.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

In this activity, learners explore liquid crystal thermometers to observe how heat flows by conduction, convection, radiation, and evaporation.

In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.

In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it

In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

In this activity about electricity, learners imagine that they are out in the wilderness and it is getting dark. Their task is to use the materials supplied to build a simple flashlight.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

In this environmental health activity, learners investigate their own vital lung capacities.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.

In this activity, learners conduct an oxidation experiment that turns old pennies bright and shiny. Learners soak 20 dull, dirty pennies in a bowl of salt and vinegar for five minutes.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.
