Polar ice samples provide scientists with valuable information about the condition of the atmosphere for hundreds of thousands of years in the past. Of particular interest is the amount of carbon dioxide in the atmosphere and its...

How has the level of carbon dioxide changed over recent years, and what is contributing it? Groups work together to research and present their findings in a creative way. Also built into the lesson is a visit to a sustainable house, but...

There is a strong correlation between the carbon dioxide concentration in the air temperature. Scholars offer explanations for the correlation in one of four AP® free-response assessment questions. Their analyses in the other questions...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Look at climate change around the world using graphical representations and a hands-on learning simulation specified to particular cities around the world. Using an interactive website, young scientists follow the provided...

If most gases are invisible, how do we know so much about them? Pupils practice associating the name, formula, testing method, and outcome for four common gases using an interactive. Users build on the content of their first puzzles to...

Carbon dioxide is not only causing global temperatures to increase, it causes the oceans to become more acidic. Lesson focuses on the blue king crab and the fragility of the habitat due to climate change. Scholars create a concept map...

Can your young chemists identify the most commonly used chemicals in the lab? Introduce the class to the go-to substances in most middle and high school chemistry experiments with an interactive. The resource offers timely feedback as...

Can you imagine Washington DC and London as close neighbors occupying the same continent? Learners will be fascinated as they step back in time and discover the evolution of the earth's continents and oceans from 4.5 billion...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

What is the relationship among the heart, circulation, and exercise? Your class members will explore first-hand how different physical exercises affect an individual's heart rate. They will begin by learning how to measure their own...

The 20th lesson plan in a 21-part series connects the wind data and expectations of a turbine to whether such devices should be built in your area. Scholars begin with estimating the wind potential at school by using long-term...

What happens in the muscles during anaerobic and aerobic exercise, and how does this affect the heart and our overall health? A cross-curricular lesson that introduces learners to the lifelong benefits of exercise, including the...

How can the circulatory system compare to a city map? Pupils distinguish the "roadways" and "vehicles" of the cardiovascular system, compare the anatomy and function of veins and arteries, and review different types of blood cells with...

Enter your household energy data to find out your family's total carbon footprint. Explore some actions to take to reduce your carbon emissions, and then find out your estimated savings once you take those steps.

Instructional module focusing on the carbon cycle. Discussion includes the biological and geological components of how carbon moves through the atmosphere, lithosphere, and hydrosphere. Site also includes an interactive practice quiz and...

Scientists have warned that as CO2 levels in the atmosphere rise an increase in Earth's temperature by even two degrees could lead to catastrophic effects across the world. But how can such a tiny, measurable change in one factor lead to...

Students will learn about how the Earth's carbon cycle works, as they examine the relationship between levels of carbon dioxide and water vapor in the atmosphere and the temperature of the ocean's surface. Includes online student...
