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)

This lesson was developed to give participants an understanding of Earth's water cycle. In this one-hour long activity, students participate in a webquest to learn about the water cycle, and then build a mini-model of the water cycle to observe how... (View More)

Water is essential to Earth's living system, the biosphere. In this lesson, students determine the types of living things within an outdoor study site, use a taxonomic key to determine the predominant land cover type of their site, then predict the... (View More)

In this activity, participants learn about the hydrosphere by making observations and taking measurements. They will go outside and use scientific equipment to investigate temperature, pH and transparency of a body of water. They will use this... (View More)

This activity was developed to get students thinking about the many ways that people use freshwater and how we can conserve this precious and fundamental natural resource. Students will watch a short documentary describing issues related to clean... (View More)

The emphasis of this lesson is deepening students' understanding of how and why we measure precipitation across the globe. Students will look at NASA Tropical Rainfall Measuring Mission (TRMM) data gathered during hurricanes and how this data can... (View More)

This is a lesson about landing site selection. Learners will work in teams to determine a landing site for their Mars Rover that best relates to their scientific question. They use technology skills to research Gale Crater through an online... (View More)

Learners model how Earth's tilt creates the seasons. They use their bodies to review the Earth's daily motions before investigating the reason for Earth's seasons in this kinesthetic exploration. The motion of the Earth about its axis (rotation) and... (View More)

Learners color images of the latest scientific data depicting the Moon's formation to create their own comic strips of our Moon's birth. The children use different-colored balls of Play-Doh® to model the impact between Earth and a small planet 4.5... (View More)

Students begin by determining dew point using an aluminum can, stirring rod, ice and thermometer. Air temperature is also measured and recorded. Students then use those two data in conjunction with the Lifting Condensation Level approximation, to... (View More)
