DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.

By building a model of a lung and diaphragm, learners discover the function of various parts of the body's respiratory system.

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?

This is a hands-on activity that uses bread and household materials to grow mold. Learners collect dust from a room, wipe it on food, and contain it. One to seven days later, mold has grown.

Learners will determine their respiratory rate and explore the factors that affect breathing rate by filling out and using the Respiratory Chart provided in the lesson.

Learners will build a homemade pump using a balloon, a mason jar, and some straws.

In this activity, learners act out the flow of blood in the human body! A great way to get learners up and moving while learning about the circulatory system.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

Make a one-string "guitar" by stringing a cup with some fishing line. You amplify the plucking of the string by placing a piezo contact microphone and mini battery powered amplifier inside the cup.

In this activity, learners make acid/base indicator paper, place the indicator paper on an anthill, disturb a bunch of ants, and then observe what happens!

In this experiment, learners isolate Deoxyribonucleic Acid (DNA) from onion cells using a simple extraction procedure.

Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.

In this activity, learners investigate balance and symmetry by designing a symmetrical butterfly, using a paper cutout.

Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!

Many common household cleaners are antimicrobials.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this activity, learners take their own pulse and explore how heart rate is affected by various activities.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

In this activity, learners create a hearing based memory game that they can share with friends.
