# Rain Gauge Activity

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)

# Water in the Biosphere

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)

# Water in the Hydrosphere

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)

# S'COOL Lesson: Estimating Altitude of Water Cloud Base

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)

# Measuring Precipitation

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... (View More)

# Exploring the Water Cycle

In this lesson, students will learn about the water cycle and how energy from the sun and the force of gravity drive this cycle. The emphasis in this lesson will be on having students understand the processes that take place in moving water through... (View More)

Audience: Middle school
Materials Cost: \$5 - \$10 per group of students

# Carbon Now

Unit two of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum examines the role of carbon and the carbon cycle in current climate. Students discover how carbon in Earth's system is monitored and also investigate the... (View More)

# Getting to the Core: Understanding Lakes through Sediment Coring

Designed as a five-lesson curriculum to introduce students to limnology, this program explores the structure, history and biology of lakes. Students analyze models, images, and a core sample from a lake case study before engineering a device for... (View More)

# Carbon and Climate in the Past

Unit one of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum introduces the role of carbon (as carbon dioxide) as an atmospheric indicator. Students examine the impact of geologic and climatic history on current... (View More)

# Carbon in the Future and You

Unit three of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum examines the role of carbon and the carbon cycle in future climate. Students discover how scientists determine Earth's average temperature and the role of... (View More)
