In this activity, students face an engineering challenge based on real-world applications. They are tasked with developing a tool they can use to measure the amount of rain that falls each day. Students will find out why freshwater is important,... (View More) learn about the water cycle, and the need to have a standard form of calibration for measurement tools. They will learn that keeping track of precipitation is important, and learn a little bit about how NASA's GPM satellite measures precipitation from space. This lesson uses the 5-E instructional model. (View Less)

Students will design, build and then test a rain gauge to measure precipitation. By sharing their results, they will recognize the need for standardization and precision in scientific tools. All background information, student worksheets and...
