Paper towers defying gravity!

Science topic - forces.

Yes folks that's right, with only A4 paper and not a lot else, year 5 rose to the challenge of preventing the earth's gravitational pull from landing a stack of dictionaries on a desk.

To give you a heads up, we answered the following:

What did we change? - The design of each paper tower
What did we keep the same? - The materials we used to create the towers. The weight of the dictionaries (for testing each tower).
Our predictions - Wider towers will be stronger. Tall towers are more likely to succumb to the earth's gravitational pull. The more paper used, the stronger the tower will be.
Our conclusion - The structure of the tower was more important than the amount of paper used. Wider structures held more weight due to surface area.

Sonny Harry and Jacob looking very nervous as they test out their tripod design...

Next up the girls with their four legged invention..

 ..and Abigail's gang (pre heart attack!).
