Water resistance


In Science, the children learnt about water resistance. They dropped equally sized, but different shaped pieces of modelling clay into water, and timed the length of drop to the bottom of the cylinder. The flatter the shape, the greater the water resistance. They did this three times with each shape, and then found the average time.
To do this, they used number skills to time and record the drops.
