Measuring a Puddle

When rain gathers on the ground it sometimes forms a puddle. This can change size during the day, which you can measure.

What you will need:

  • A puddle
  • A piece of chalk

What to do:

  1. Choose a day when there has been rain overnight and the rest of the day is expected to be dry, warm and sunny.
  2. Choose a puddle and first thing in the morning use a piece of chalk to draw around the puddle.
  3. A few hours later go back and draw around your puddle again. Repeat this several times during the day.
