How is rainfall measured? Students can find out with a rain gauge they make in class! What’s more, they get to upcycle a plastic bottle that might otherwise sit in a landfill.

The only supplies you’ll need include: 

  • Empty two-liter plastic bottles
  • Scissors to cut the bottle 
  • Clean pebbles, gravel, marbles, or glass craft stones (the stones can be purchased at many dollar stores) 
  • Masking tape
  • Rulers
  • Permanent markers
