This activity is the perfect independent STEM activity for preschool and kindergarten science centers. Laminate a copy of the printable so that kids can use it over and over again. You can also divide your classroom into groups and complete the activity together.

Provide the kids with a variety of different-sized objects. There are three examples on the worksheet, but you can try more objects if you want.

In our experiment, the kids used foam dice, toy dinosaurs, and river rocks.

Have the kids fill the jars with their chosen object, counting as they go to see how many of each object fits into each jar.

We got 28 dinosaurs to fit in the jar, 12 river rocks, and 3 foam dice.

When the jars are full, have the kids record their results on the printable. They can write in or draw their answers.
