Boats and Buoyancy Project
We were extremely excited to start our experiments today to help us learn more about why and how boats float. The following video show the experiments we did to learn more about floating and sinking.
Displacement - Rock in water
This experiment tested displacement. Can you remember what displacement means? Remember we talked about the bath tubs and swimming pools and what happens with the level of the water when people get in.
Density - The Uncooked Egg in Water
This experiment tested density. What does density mean? Remember when we stood on the carpet and Ms. Pahl had us stand on the carpet and she threw the egg (cushion) into the water (us).
Fresh water and an egg
Salt water with en egg
The Apple and the Paper Clip
The following video shows the test we did for weight and volume. Which object sunk and which one floated?
