Suggestions for Fruit, Nuts, and Candy
Here are a few suggested fruits, nuts, and candies to use in this activity. You don't have to buy all of these, but try to choose ones that come in a variety of shapes and sizes.
 
1 walnut (in the shell) What does this stuff represent?
Why are we experimenting with Jell-O, fruit, nuts, and candy? It's not just because they're delicious! In this activity, imagine that the bowl of Jell-O is space and the pieces of fruit, nuts, and candy are planets, stars, and other objects in the universe. Just like matter in space, the fruit, nuts, and candy come in different sizes and masses. Once you've selected your fruit, nuts, and candy, separate the ones you think have very little mass from the ones that have a lot of mass. Are the biggest "stars" and "planets" always the ones with the most mass?
