THE RESULTS ARE IN
We tested our hypotheses today, followed the procedures, got some results, and drew conclusions.
Here's what happened (with a few extra things thrown in for good measure)...
Floaters: pencil, wooden block, golf tee, wooden stick, bouncy ball, Lego
Sinkers: paper clip, iron button, dice, sea shell, penny, marble, bread tag
We decided wooden things float and metal things sink. We also decided that some plastic things float and some plastic things sink. This was interesting and stumped us for a little while! We took a good look in the water and decided that it mattered how an object is shaped and how much oxygen an object has in it to determine if it would sink or float. We also decided there are some other things we need to test at home. So beware...you might find some sinking and floating toys tonight. Though we did discuss the fact that phones and electronics are going to have to remain a mystery.
In other news, can you use a combination of smaller shapes to make a bigger shape? How many different ways can you make that shape?
