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 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.

In this lesson, students will describe at least two problems with burning fossil fuels and recommend solutions for reducing use of fossil fuels.

In this craft activity, students will recognize, name, and compare the fractions 1/2, 1/4, and 1/8 by constructing a penguin out of portions of paper circles.

In this lesson, students will work collboratively to tackle a water conservation issue at home or in their school.

In this lesson, students participate in a kinesthetic simulation to illustrate how nutrient pollution from agricultural runoff can lead to a dead zone at the mouth of a drainage basin.

In this lesson, students will learn how galaxies around us formed and what their stories can tell us about the past, present, and future of our Universe. Students will also have the opportunity to work with astronomers to study and classify galaxies.

In this activity, students play a simple card game based on the stages of metamorphosis in insects.

In this activity, students will learn about common adaptations seen in three ocean habitats and then make predictions about what animals call that area home.

In this lesson, students will practice distinguishing between correlation and causation within the context of global climate change. Students will think critically and analyze different claims and datasets related to what might be causing increasing temperatures in a fictitious town called Solutionville, as well as around the globe. Although students will be working within the context of a fictitious town, the temperature and carbon dioxide data they will be analyzing are real and will enable them to see relationships between global temperatures and atmospheric carbon dioxide levels. Finally, students will watch a video in which they will be learn that the burning of fossil fuels releases carbon dioxide into the atmosphere, and they will begin to explore the connections between human activities and global climate change.

This video explores key water issues, the water cycle, and some of the technology and techniques used to conserve water. A set of discussion questions and post-viewing activities are provided.

In this lesson, students will design and use a simple model to test cause and effect relationships or interactions concerning the functioning of a marine food web, ranking their hypothetical ecosystems according to their stability when faced with a natural or man-made disturbance.

In this lesson, students will learn that the rainforest is divided into layers. They will also learn that different plants and animals inhabit different layers and serve different functions in the rainforest.

This kinesthetic activity will demonstrate concepts like rotation and orbit, clarify movement and direction, and help students understand why earthlings see different things in the sky.

This kinesthetic activity demonstrates to students that the earth's tilt is what is responsible for shifting light patterns and the change in seasons.

In this interactive lesson, students will learn what "retrograde" and "opposition" means in astronomy while modeling this phenomenon.

In this activity, students will use models of Earth, the Sun, and the Moon to discover why moon phases occur. Students will also learn the order of the moon phases from one full moon to the next.
