Measuring Rain

• With a partner
• Look at the materials and tools available and
  plan your device to measure rain on the capture
  sheet.
• Show the teacher your plan.
• Make your device!

5
Test your device

• With a partner
• Pour water over your device for 10-15 seconds.
• Answer the Explain questions on the capture
  sheet.
• Empty the device and pour water a second time.
• Change any of your answers if needed.

6
Evaluate

• What did you find difficult about this task?
• Which design do you think would be the most
  effective for measuring precipitation? Why?
• What are some design factors that you think need
  to be consistent for the rain gauges? Why?
• What could you do to improve your rain gauge?

The Global Precipitation Measurement (GPM)
Satellite will collect precipitation data from
around the world. Knowing where and how much
rain or snow falls globally is vital to
understanding how weather and climate impact both
our environment and Earths water and energy
cycles. Precipitation patterns have effects on
agriculture, fresh water availability, and
responses to natural disasters.
