In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this activity, learners discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

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

In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

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

Using simple materials, learners will construct the end effector (grasping device) of a robotic arm and use the device to capture and pick up an object.
