Fill a can up with water to show how a submarine sinks
Then blow air in it with a straw to make it come up again.
Then I asked them to make their own boats and fill out a page that has a picture of their boat, and answer the questions:
1. Does it float?
2. Does it move?
3. If it moves, how?
4. Does it carry cargo?
The picture that Ellie drew looked NOTHING like this! It did look like a ship, though! She told me that she had a horn and a telescope. It didn't float. I don't think it even stayed together, but she did use a TON of creativity! I love to see what is going on in their minds.....
None of them worked. Not even mine. I put a motor on it but we couldn't get the wires to stay on the battery to get it to move.
It's okay, though because there was a lot of problem solving going on.
