In this lesson, students will be able to describe the various processes of the water cycle in the Amazon. By performing a skit, they will understand the changes water goes through throughout the water cycle and that this cycle runs continuously with different processes happening at the same time.

In this lesson, students will learn that ice formations on land will cause a rise in sea level when they melt, whereas ice formations on water will not cause a rise in sea level when they melt. They will also learn that ice is less dense than water, that ice displaces water equal to the mass of the ice, and they will practice some of the steps involved in a science investigation.

This lesson is composed of three challenges, each addressing a different aspect of how to design an efficient public bus system for a fictitious town while taking into account the benefits and drawbacks of various fuel options. In attempting these challenges, students will find that there is often more than one way to solve a problem. The purpose of these challenges is for students to reason out their own logical methods for solving a problem using math and computational skills with little initial guidance.

This video discusses how humans can reduce their carbon footprint by making different transportation choices. A set of discussion questions and post-viewing activities are provided.

In this lesson, students create simple illustrations of how carbon flows between the biosphere, hydrosphere, atmosphere and lithosphere. Students will also use the provided materials to tell the story of how human activity can contribute to global climate change.

In this activity, students will learn that there is a finite amount of carbon on earth, which moves around in the environment, from one place to another.

In this lesson, students will participate in a natural selection simulation, flipping pennies to mimic the probability of passing on certain traits. The traits are the three genes for color-vision, found on the X chromosome. In the simulation, students will simulate six generations of primates, and track how the gene pool changes over time. The activity loosely mimics some of the mechanisms that led to the evolution of our own improved color vision.

In this two-part inquiry-based activity, students will practice using the scientific method while learning about decomposition, exploring how some types of garbage will decompose while others will not. Students can then go on to design their own experiment to test different variables affecting the rate of decomposition.

In this lesson, students use the imaginery location of Conservation Island to teach students about some of the real-world issues involved in making conservation plans to save endangered species.

This video discusses the impact climate change is having on coral reefs around the world and what we can do to preserve these important and diverse ecosystems. A set of discussion questions and post-viewing activities are provided.

In this activity, students take action on a local or national cause they care about by creating a campaign.

This video explores the pros and cons of desalination. A set of discussion questions and post-viewing activities are provided.

In this activity, students demonstrate the role density plays in water circulation and paves the way to discussing thermohaline circulation.

In this lesson, students combine information from world maps to create their own maps of tropical rainforest locations and discuss how living and non-living components of an ecosystem influence each other. Studenst work in small groups to create their maps to specific guidelins and then discuss in a whole group format. Downloadable materials are included in this lesson.

In this lesson, students will determine the locations of tectonic plate boundaries and use seismic waves to pinpoint the epicenter of an earthquake.

In this activity, students learn about the lifecycle of the Emperor penguin and play a game to model some of the harsh conditions faced by the penguin parents.

In this two-day lesson, students will be introduced to several water sustainability issues, including access to clean freshwater, groundwater depletion, agricultural water use, and water waste.

In this two-day lesson, students will be introduced to several issues related to the social, economic, and environmental impacts of our current food system, including food waste, food deserts, agricultural land use, and the environmental impacts of diet choices.

In this lesson, students will learn the characteristics that make an animal a fish, create a model of a fish, and compare it to other marine animals to decide if they are fish or not.

In this activity, students learn about plant reproduction and use real data to construct explanations about which flowers are the most attractive to different pollinators.
