Visualize the gravitational force that two objects exert on each other. Change properties of the objects in order to see how it changes the gravity force.

Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it!

How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today. What happens when you add clouds? Change the greenhouse gas concentration and see how the temperature changes. Then compare to the effect of glass panes. Zoom in and see how light interacts with molecules. Do all atmospheric gases contribute to the greenhouse effect?
The HEART Force curriculum builds understanding of wildfire, flood, or drought in the context of place-based community resilience.
In this interactive game, students work in three "resilience teams" to solve community challenges that arise during the course of an extreme drought event by using available individual and community resources.
This interactive game has students work in three “zone response teams” to solve community challenges that arise during the course of an extreme flooding event by using available individual and community resources.

This activity encourages students to collect data to answer questions, explore the roles of individual macroinvertebrates in aquatic ecosystems, and think about the health of aquatic ecosystems relative to the macroinvertebrates found.
In this design challenge lesson students explore the Denver Public School District’s solid waste plan and discuss how their school can save or decrease emissions by reducing solid waste at our school.
This lesson provides guidance for students to create and practice a presentation about design challenge results that they developed in the previous unit lessons and how to present it to the school administration.
In this activity students utilize collected data and propose solutions to mitigate food waste in their school.
This lesson outlines for students how to design and carry out an investigation to audit their school’s food waste system.
Students explore the greenhouse effect in this lesson using a computer simulation and develop a model for how it works.
In this design challenge lesson, students examine their school food system and develop an investigation about food waste in order to know what should change.
This lesson has students create a hands-on model that accurately explains seasonal changes on Earth and develop knowledge of the Sun-Earth system.
In this lesson, students investigate the life history characteristics of different Antarctic penguin species and identify the changes that their populations have experienced.
In this lesson, students explore how human activities will continue to impact Antarctic ice, discuss human contributions to climate change, and investigate what we can do to stop/reverse these negative effects.
This lesson has students explore how the gases trapped in ice cores over the last quarter of a century can be used to understand how Earth's atmosphere has changed in the past.
