Over the weekend we completed lesson 1 – Apologia Swimming Creatures
(The below experiments were taken directly out of the curriculum itself)
Thankfully my husband will be doing most of the science experiments with the kids this year! He enjoys science so I volunteered him!
1st Experiment:
Pressure on lungs
materials needed:
small balloon
2 liter bottle
Hold balloon in bottle upside down so the top of the balloon and the opening of the balloon is sticking out of the bottle opening.
As you dive deeper, the pressure on your body increases, just like this balloon. your lungs get smaller!
Stepping on the bottle stimulates what happens to your lungs when you dive down into depths of the ocean.
2nd Experiment
What is heavier cold or hot water?
materials needed:
food coloring 2 different colors
hot and cold water
large clear bowl
little cup (Styrofoam or dixie cup)
1st time dropping food coloring into cold water, then using hot water dropping the food coloring in – we found the the cold water was heavier because the 2 colors did not mix, they stayed separated once both colors were but in the container together.
