During this lesson, learners will determine their blood pressure and learn about systolic and diastolic pressures.

Learners listen to and try to decipher a radio message that was sent from Earth to possible intelligent civilizations.

Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

This is a game that is sure to sharpen players' basic math skills. Players must use four randomly selected numbers to create an equation that equals a fifth number.

In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.

In this activity, learners build their your own seismograph with household materials to document shaking.

If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.

Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.

In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

This is written as a static display, but can easily become a hands-on experiment for learners.

In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this twist on a classic design challenge, learners will try to stop a bouncy ball from bouncing as they explore how to control the fall of an object.
