In this exploration activity, the teacher puts together 10 cans of soda that have a different mass, based on the gravitational force of each planet and our moon. The cans take a little bit of time to put together, but I have reused my set for 10 years with no issues, so the initial time has been worth it.
Students find the mass of each can and look for patterns between the mass of the cans and each planet's diameter and density. The purpose is to help students learn the factors that affect gravitational force.
My students especially love feeling how light a can of soda would be if it were on Pluto or our moon. They are always in awe of how heavy the Jupiter can is.
This label requires digital scales or triple beam balances. Sand can be used to fill the cans, instead of pennies. Just measure the appropriate mass and use a funnel.
