  • A dark sheet of construction paper and a rainy day.


  1. On a rainy day go outside and hold the dark construction paper parallel to the ground in the rain.
  2. Collect at least 25 drops of rain. This should only take 5 to 10 seconds. Then return to the classroom and observe the raindrops on the paper.


The raindrops made marks of various sizes on the construction paper.


Raindrops are different sizes some as small as 1 millimetre and some as large as 1 centimetre or 10 millimetres. A raindrop is composed of tiny water droplets. Many water droplets are present in a large raindrop and few water droplets are present in a small raindrop.
