1. Make a shape of a
modelling clay figure 3.5cm (1.25in) long. Fix the paper-clip to its
head and hang it from the pen top. Fill the bottle with water and drop
in the scuba diver.
2. The pen top should float with its top just above the water level. Make the figure bigger or smaller if needed. Then pour in more water and screw the top on tightly. What happens to the diver??
What happens when you squeeze the bottle?

I had to change it a little because when i tried it didn't work. What i did was i changed the pen lid to a straw and i changed the clay model to be made out of metal and it worked really well. What happened was when i squeezed the bottle the person sank and when i let it go it floated back up to the top. I think that happened from when i squeezed the bottle the density grows bigger so the water go up into the straw and forces the diver down.

When I squeezed the bottle, the diver sunk! I think it was because the lid got filled with water. The lid first didn't have any water in it. So there was nothing to keep the diver afloat and it sunk.
ReplyDeletewhen i squesed the bottle the diver sunk.I think tjis is because the lid got filled with water so it be came heavy so it sunk.
