# Identifying the Key Changing Conditions of the Earth System (Grades 10-12)

In this unit, students investigate temperature cycles, tree rings, CO2 records, and the effects of CO2 on temperature, precipitation and cloud cover to determine the impacts of changing climate on forests. After gathering and analyzing local data,... (View More)

# The Earth as a System (Grades 10-12)

Students are introduced to the carbon cycle through discussion, modeling and a game. Students then complete activities and investigations on Greenhouse gasses, photosynthesis, cellular respiration and ecosystem services (functions and values of... (View More)

# Blue Marble Matches: Using Earth for Planetary Comparisons

This activity is designed to introduce students to planetary geologic features and processes. First, students will use NASA satellite images to identify geologic surface features on the "Blue Marble" (Earth), and will explore the connection between... (View More)

# The Water Cycle: Now You See It, Now You Don't

This is a hands-on lab activity about the water cycle, specifically evaporation and condensation. Using materials such as clay, ice and a lamp, learners will observe the relationship between temperature and condensation and temperature and... (View More)

# Evaporation Investigation

This is a hands-on lab activity about evaporation. Learners will conduct experiments to observe the process of evaporation. They will then describe the process of evaporation, and the general water cycle, through discussion and pictures. Background... (View More)

# The Nature of Salt

This is a hands-on lab activity about the composition of salt. Learners will explain the general relationship between an element's Periodic Table Group Number and its tendency to gain or lose electron(s), and explain the difference between molecular... (View More)

# Density: Sea Water Mixing and Sinking

These two hands-on labs are about the role of temperature and salinity in governing the density of seawater, a major factor controlling the ocean's vertical movements and layered circulation. In the first activity students work in groups to... (View More)

# Can you Show that the Temperature of Air has an Effect on its Weight and its Direction of Vertical Movement?

This activity has two purposes: challenge the learner to develop a procedure for investigating a research question and to learn more about factors affecting the dynamics of air in motion. It demonstrates that warm air and cold air differ in weight... (View More)

# Design Challenge: What Factors Determine the Comfort of Air?

The purpose of this investigation is to understand how the amount of water vapor in the air at various temperatures affects the way the human body responds. This is an important basic concept for understanding why one might feel either comfortable... (View More)
