Ask students how the stuffed animal will be affected by gravity on the Moon vs. Show your stuffed animal on our model Earth and on our model Moon. Make sure students are understanding that the amount of the force of gravity or gravitational pull is relative to the size of the object.ħ. Keep asking directed questions until students hit on this answer. Ask them if the force of gravity will be the same on the moon as it is on the Earth? If students say gravity will be less on the moon then ask why? You are looking for an answer that relates the fact that the Moon is smaller than the Earth and therefore has less gravity.Ħ. Gravity or gravitational pull is the force that attracts our stuffed animal back to our model Earth in the same place it jumped from.ĥ. Explain to students the reason why our stuffed animal lands in the same place is because of the force of gravity. Once again asked the students where this animal will land if it jumps? Go through this step in several locations until students understand that no matter where the animal is placed on our model Earth after jumping they will return to the same spot.Ĥ. Place the stuffed animal on the side of the model Earth. Place your animal on your Earth and ask students if the animal were to jump where would it land? If they need help, ask them when they jump where do they land?ģ. For example if you have a small teddy bear, you can introduce your animal as Astro-bear.Ģ. Now introduce your stuffed animal as astronaut _. Show students your large ball and tell them it represents the Earth. We recommend you watch this teacher demonstration video to visualize this demonstration.ġ. An object's mass is constant in all circumstances contrast this with its weight, a force that depends on gravity. Mass is usually measured in grams (g) or kilograms (kg). Mass is a measure of the amount of matter in an object. Earth's gravity is what keeps you on the ground and what causes objects to fall. The more massive an object is, the stronger its gravitational pull is. Anything which has mass also has a gravitational pull. Gravity is a force which tries to pull two objects toward each other. 1 small stuffed animal from modeling how gravity attracts an individual.

1 much smaller ball for modeling the Moon.
