Water IV - Floating and measuring


Hello friends
How are you?
We are well, and tomorrow we return back to school, after Easter. This week is a busy week for us, for we have mother day next week-end. So we are not abble to work in the project this week. We will begin the trip to the earth next week. But we still have some water expiriences to post so we are going to do it. We will post two expiriences today, and other two tomorrow. But this are not chemestry expiriences. These are phisics expiriences. Do you know why? We will tell you the answerd in the end of the week because we shall do a chemestry present to our mum´s.
The first expirience is about floating. What do people mean when they say that it floats?
Do you want to see?

We conclude that:
An object floats in the water if it does not go to the bottom.
The flutuation on the water depends on the objects.
Objects with identical shapes and sizes may float or not.

The second expirience was about measuring the water.

We conclude that:
Water was no shape. It adapts to the shape of the container.
The same amount of water can take diferents heigths, depending on the countaired that is placed.
When we change the water from a countainer to another, the amount does not change.

It is not scientific, but it was really magic! Our Easter...


Last friday we had a very good surprise. When, during the morning Hugo went to the computer to open the daily mail, He found a message from the Easter bunny saying that, during the nigth, we passed in our kindergarten, and he left hidden in the garden some easter egs for us. We were really happy with the new and we went into the garden to look for them...
