2. Design a boat that can hold the maximum number of passengers using the given materials.

3.  Soya beans  Dried peas  Plasticine  tinfoil  container of water

4.  1. Divide pieces of platicine into two equal pieces or cut one piece of tinfoil into two equal pieces.  2. Make two different shapes of boats using the plasticine or tinfoil.  3. Put one boat into the basin of water.  4 Add soya beans or dried peas until the boat sink. Whichever boat held the most was the winner.

5.  use the same amount of plasticine or tinfoil for each boat to ensure it is was a fair test.

6.  : water pushes upwards with a force called upthrust ( you can feel this if you try to push a light object such as a balloon or aero board under water). The shape of a boat affects the weight of the passenger’s or cargo it can hold. The more water the boat can disperse the more weight it can hold. 
