In this activity, learners explore the process of condensation.

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.

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.

This activity (located on page 4 of the PDF under GPS: Sea Turtles Activity) is a full inquiry investigation into testing a repair material.

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

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 water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

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

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

In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

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