Science: Fruit & Veggie sink or float

thanksgiving-science-fruit-veggie-sink-or-float

Thanksgiving is all about FOOD (thankfully!). So we decided to use that to our advantage and mix it in with our science experiment this week.

This experiment is again, working on predictions and recording the outcomes. (Use our prediction worksheet here)

What you need:

  • 4-6 different, whole vegetables or fruits–we use broccoli, carrots, pumpkin, green pepper, zucchini and an apple.
  • Bowl or tub with water
  • Prediction worksheet

This is a great mess-free experiment (except for the occasional splash)! We lined up the vegetables, let the kids touch/hold each one and make their prediction on the sheet. If you are doing this with your class, you could also take a class vote on each veggie, wether it will sink or float.

Have each child take turns dropping on of the items into the water, one at a time, and watch what happens!

Why do some sink and some float? 

Whether a fruit or vegetable sinks or floats has a lot to do with its density. What is density? It’s how heavy an object is compared to its volume. Imagine lifting a pillowcase full of feathers. Now imagine lifting a pillowcase full of apples. Which one would be heavier? They are both the same size, but since apples are denser than feathers, the one with the feathers in it would be heavier.

Happy Exploring!
