The Last Week!


I am so pleased that this will be the last of our online science lessons and that we will all be able to see each other again.

I am sooooo, excited!

However if we have to stay home this week then lets do some more science magic.


I have a question for you.

If you put paper in water will it get wet?


Lets try it out




F2 Science Magic

What ideas can you think of to keep the paper dry?

Now lets see some magic



F2 Science Magic 2


Why do you think this happened?

Does it happen every time?

Does the same happen with different materials? Would the same happen is you used cloth?

Try wrapping a toy in some paper and see if it still stays dry?


So why has this happened?

This is because an empty glass is not really empty. There is air inside.


Grown ups as an further explanation for you to discuss further

The air inside the glass is trapped when the glass is pushed down into the water. It cannot escape because air is lighter than water and it stays above the water. The trapped air then pushes the water away keeping it from touching the paper towel. When air and water push against each other, they are exerting pressure, i.e. air pressure and water pressure. In this experiment, air pressure prevents the water from entering the glass. That is why the paper towel could stay dry.
