This experiment will demonstrate the rotation of Earth and help students understand how the sun and moon rise in one part of the sky, move across the sky, and set. It will also help them know why stars other than our sun are visible at night but not during the day. Have students draw a line across down the center of the paper plate, drawing a day scene on one half and a night scene on the other. Then cut a paper plate in half, attaching one half to the plate. This half plate represents the rotation that happens throughout the day. As students rotate the half, they will see different parts of their scenes. Have students discuss what time of day it is at various stops in the rotation.

Using just cornstarch and water, have students make their own quicksand to explore suspension. This quicksand can be a liquid when there is no pressure on it, but it can be a solid when pressure is added. Pressing the quicksand into a ball in your hand will make the mixture hard, but when you relax your hand, the mixture will liquify.

Students will get the chance to test their reaction time with this experiment. Have one student hold the ruler above another student’s hand. The student who is attempting to catch the ruler needs to have their hand in the form of a claw, ready to catch the ruler when it’s dropped. When the ruler is released, the student will close their hand and see how many inches it took them to catch the ruler. Allow students to try and beat their own personal records. This experiment allows students to see the connection between the eyes, the brain, and the motor neurons that automatically fire when we are reacting.
