Science Experiment: Does it Float or Sink?

      Yesterday we were supposed to do an experiment involving learning about air pressure. Well, the preparatory part didn't go well...and I couldn't get it to work... lol! Go me! Haha! So thankfully I remembered that I had already printed out a few worksheets, and one of them was the sink or float experiment. A while back I found this site (not sure how...Pinterest probably) and printed out the worksheet along with a bunch of other stuff to have around for occasions such as this. :-)  The site is here:  http://www.themeasuredmom.com/water-math-science-activities-for-kids-ages-3-6/ .
      I filled up the biggest bowl we had with water and found a pencil, coin and crayon. Then I called the boys in and told them to find other things like the objects I found to see if they sink or float. Of course this ended up with A LOT of interesting options...so I chose the most variety I could. This included things like; bouncy balls, a toy ninja, a plastic toy chain and so much more... ;-) I wrote down all the objects they chose, then we went through the list and they decided whether they thought it was going to sink, or float. Next was the fun part! They dropped each thing in the bowl one at a time and watched it sink or float! Then they went back to their worksheet and filled in whether each thing sank or floated. They got some right and some wrong, and amazingly enough didn't really care that they had been wrong. The really awesome part is after they were done, they kept finding new things and trying them in the bowl for another half an hour after we were done! That's what I call a successful experiment! (P.S. I'm fully aware they're in their pj's for this...yay for school in your pjs!) :-)
