Rain Gauge Redesign - Precipitation Analysis. Weather enthusiasts, get ready to redesign a rain gauge in this hands-on activity! In this worksheet, you will draw and label your redesigned rain gauge using different materials and shapes from the standard rain gauge. Then, you'll place both the standard rain gauge and your redesigned version in an area where they can collect rainwater during a rainy period. Measure and record how much water each rain gauge collects. Analyze your data to determine which rain gauge design is more effective at accurately measuring rainfall. Explore the strengths and weaknesses of each design and discuss your findings with your classmates. This activity will help you understand how weather instruments can be improved through engineering.
