How many drops of water can fit in your bathtub?

Yesterday we calculated the number of drops of water in a bathtub.

First of all we decided that the mathematical modelfor a bathtub is a parallelepiped.

Students measured their bathtubs at home and the dimensions were 70x170x38 cm.

Then the volume is 452200 cubic centimetres

Finally, we decided to use a dropper and count how many drops were there in 1 cubic centimetre.

We went to Chemistry laboratory and count.

Our results were: 35, 25, 21, 20, 22, 23, 35, 30, 25, 36.

Calculating the mean, it was about 27.

So the number of drops was 12209400!!!!

Thanksgiving Day

It's celebrate in different ways: what families normally do is getting together to have a traditional dinner where turkey is the main dish. Moreover, Macy's, a very big shops chain make a vey famous parade in Broadway's avenue. And the very important thing is that it's an important day because next day starts Christmas purchase season!!!
