What Floats? What Sinks? is the second activity from our Sink-Float littleBLAST science kit. You can read all about the first activity and our review here! Caden enjoyed learning more about sinking and floating with this activity, just as much as he did with a similar activity a few weeks ago.
For this activity we tested a styrofoam cube, a denser foam cube, a ping-pong ball, a small rock, a marble, a ball of play dough, a small metal screw and a plastic wall anchor.
Caden tested each object one at a time. But what was different about this activity is that I had him predict whether the objects would sink or float before testing them out and he had to circle his prediction on the sheet from the kit.
This was the first time Caden did any sort of writing, pretty much ever. I guided him through each prediction and pointed to the arrow he needed to circle based on his prediction. Up arrow for float and down arrow for sink. Caden did surprisingly well circling his predictions and stayed on task the entire time.
During the course of the experiment, Caden discovered that play dough gets really squishy if it is placed in water. So after we finished testing each object, I allowed Caden to play with the play dough and some of the other objects in the container of water. It was a big mess to clean up when he was done, but its all part of the process of exploring science with your senses.
And now it’s time for the Saturday Science Blog Hop!
