In this activity, learners simulate taking HIV antiretroviral drugs by using Tic Tac mints and Kool-Aid packets.

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

In this activity, learners will turn cream and salt into butter—using marbles. Learners will explore how shaking up fat globules help them create homemade butter.

In this health activity, learners explore breathing, lungs and asthma. Learners test their lung capacity by blowing air into balloons.

In this activity, learners will experiment with water- and air-filled balloons as a way of dampening sound before it reaches their ears.

In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this health activity (page 5 of the PDF), learners will explore a unique connection betweeen the bones of the body.

In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

In this activity, learners will explore the foods that are in their kitchen and what sugars are inside of them. Explore nutrition and food labels to better understand the foods you eat.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, learners create slime to model mucus and examine how it collects simulated particles. Mucus keeps particles from the environment out of our lungs when we breathe.

In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.
