In this interactive game, students solve the challenges that their community faces during the course of an extreme flooding event by using available individual and community resources. Students work in three zone response teams to determine the responses they will take in each round as the flood situation evolves.

In this interactive game, students solve the challenges that their community faces during the course of a wildfire event by using available individual and community resources. Students work in three zone response teams to determine the responses they will take in each round as the wildfire situation evolves.

Build equivalent fractions with different denominators. Match shapes and numbers to earn stars in the game. Challenge yourself on any level you like. Try to collect lots of stars!

In this hands-on activity, students examine how the orientation of a photovoltaic (PV) panel -- relative to the position of the sun -- affects the energy-efficiency of the panel.

This video describes how Colorado has planned for and uses clean energy resources to reduce its carbon footprint.

Number Play from PhET is a sim for some of our earliest learners and includes multilingual support. This sim can be used to teach topics such as counting, cardinality, grouping, and subitizing. Students will enjoy interacting with fun objects and challenging themselves with the counting and subitizing games.

Teachers have access to simulation-specific tips and video primers, resources for teaching with simulations, and activities shared by our teacher community.

PhET provides fun, free, interactive, research-based science and mathematics simulations. We extensively test and evaluate each simulation to ensure educational effectiveness. These tests include student interviews and observation of simulation use in classrooms. The simulations are written in Java, Flash or HTML5, and can be run online or downloaded to your computer. All simulations are open source (see our source code). Multiple sponsors support the PhET project, enabling these resources to be free to all students and teachers.

This is a hands-on activity students design, build, and test. They compare the energy-generating capacities of vertical- and horizontal- axis wind turbine prototypes they have built as potential sources for power in a home.

This small-group activity uses engineering concepts to design energy systems for three off-the-grid towns in Mali, Ethiopia, and Namibia.

Students describe the steps in a product life cycle assessment and suggest ways to reduce the environmental impacts of engineered products.

Students work in pairs to pick black and white beads out of a bag to represent the percent of renewable and nonrenewable resources used in different countries, and then graph the information.

In this activity, students explore real data about renewable energy potential in their state using a mapping tool developed by NREL (National Renewable Energy Laboratory) to investigate the best locations for wind energy, solar energy, hydropower, geothermal energy, and biomass.

In this activity, students become familiar with the online Renewable Energy Living Lab interface and access its real-world solar energy data to evaluate the potential for solar generation in various U.S. locations.

In this activity, students work through the process of evaluating the feasibility of photovoltaic solar power in 4 different US cities.

In this activity, students play the role of energy consultants to a CEO, assessing and documenting the feasibility, cost, and environmental impact of installing solar power on 4 company facilities with the same design but in different geographical locations.

Explore what it means for a mathematical statement to be balanced or unbalanced by interacting with integers and variables on a balance. Find multiple ways to balance x and y to build a system of equations.

This lesson plan has students working in small groups to research the Mountain Pine Beetle in Colorado and other inter-mountain Western states. Students identify the factors that control pine beetle population and research how warmer winters and decreasing spring snowpack allow the population of pine beetles to expand.

This video takes viewers high into the Rocky Mountain snowpack, where researchers dig snow pits to explore the source of Colorado's water supply. Highlights the importance of snowpack on the supply of fresh water available in western and southwestern states. Snowmelt dynamics are discussed, including the impact of a warming climate.

This video provides a good overview of ice-albedo feedback. Albedo-Climate feedback is a positive feedback that builds student understanding of climate change.
