SCIENCE EXPERIMENT for 2nd cycle

Hello!
During the first term we are going to experiment with different densities.
Can you predict what is going to happen when we mix all the liquids?
Let's experiment...
What happened?

This was the result of our 3rd and 4th grade scientists...

Floating egg experiment

The Salt Water Egg Experiment explains why materials (such as an egg) float more in salt water than in fresh water.

Will it float or sink?


Have you ever tried swimming in the sea? Did you notice that you could float more easily in the open waters than when you're swimming in fresh water or even in a swimming pool? This experiment will help you understand why!

Density tower experiment

Today we work with different liquids:

Dish soap, water, condensed milk, sunflower oil,  body oil and a grape.

We talk about what is going to happen when we pour them in a glass...

Some pupils say they will mix. Some pupils say they will stay separate.

Then they predict which one will stay at the bottom and which one on top.

This is what happened...

After that we watch a video to see what happens with other liquids.

After the experiment we see that

MORE DENSE LIQUIDS STAY AT THE BOTTOM, 

LESS DENSE LIQUIDS FLOAT.

Each layer is less dense than the one below it.
