Design a Boat to Carry the Most Dried Peas
An Experiment by 5 and 6 Class

Fair Test :

It was a fair test because each of the groups got an equal
amount of plasticine and water and a dish the same size.

Our boat was better than the others because it was a long
thin shape, so it could hold a lot of dried peas.

We made the base of the boat thin, so it would float, and
long so any one part of the ship wouldn’t be much heavier
and so it wouldn’t sink.

I learned that you can make a boat with plasticine that will
float, and will hold an object, while the same weight of
platicine will sink if it’s in a ball.

I learned that boats float because they displace the water,
so it will float as long as it displaces enough water. The
more water it displaces, the more it will float and the more
weight it will carry.

By Ciaran

Our boat was the best because it was long and it did not
Break the surface tension. We rolled it out as thin as we
Could. As a result of that it held more than the other
boats.

Boats do not sink because of the way they are shaped, so
They displace the water and so float.
by 6th class

Our class was divided into 4 groups. Each group
designed a boat out of equal amounts of plasticine.

One boat was shaped like a deep bowl and held 59 peas.

One boat was shaped like a shallow bowl and held179
peas.

Another one was shaped like a rectangular bowl and held
212 peas.

One boat was long and narrow, and held the most peas.
It held 236 peas.
