In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

In this activity, learners discover how gelatin can be used as a medium for drug delivery. Learners create colored gelatin and then cut out pieces of the gelatin to simulate medicine (pills).

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

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

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.

In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners explore rocketry and the principals of space flight.
