How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

Sculpting can be a rewarding way to accent a lesson plan in any subject. This project requires learners to design and sculpt a head out of clay. The entire process is outlined in this resource; including photos and suggested materials....

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

A getting-to-know-you activity that is perfect for the beginning of the year! Kids craft their portrait out of clay, then make a mobile by dangling ceramic representations of things they love. This project builds self-awareness, motor...

A critical look into the structure and function of ecosystems is here for young learners as a series of lessons and worksheet activities. Topics covered include land-based and marine ecosystems, connections to the water cycle, food...

What kind of experiment can your class do to how observe the environment effects on organisms? Groups design and conduct lab experiments to learn about the effects of the environment on aquatic organisms. Based upon knowledge gained...

Your teenagers may have heard of fracking, but do they really know what it is? And could they debate the benefits and risks? Educate your environmental science class with a lesson about hydraulic fracturing, non-renewable energy...

If the world were 100 people...17 would not have access to safe drinking water, 18 would not be able to read or write, and 52 would not have a primary education. Using the theme of "100 people," this resource explores other major issues...

Students conduct an experiment. In this water lesson, students watch the lesson "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their items. Students discuss their...

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

Develop a model of a wastewater treatment center. The last activity of the unit has pupils mix a lake water sample into a tank of water containing fertilizers. Over time, the algae from the lake water grows and removes the nutrient-rich...

Responsible farming is important for maintaining natural resources. Eager scientists complete a WebQuest to explore what happens to nitrogen when it enters the soil. They learn about the chemical makeup of nitrogen-based molecules...

How do chains of islands form? Young oceanographers explore the mountains of the deep in the final installment in a 13-part series. The interactive compares types of seamounts based on their overall height and height under the water, as...

Learners identify and describe various organisms living in a pond water environment. They describe the characteristics of living things. Students compare and contrast organisms created by asexual reproduction and sexual reproduction....

Students construct a thermoscreen for the experiment. In this earth science lesson, students make observations and interpret them using synoptic codes. They predict the weather based on gathered information.

Take your science class on a hypothetical field trip to Mars with an engaging astronomy lesson. After first learning about NASA's Mars rover missions, young scientists plan their own scientific investigations of Earth's...

How can you predict the weather without any technology? Young scientists learn to forecast the weather using traditional Native American techniques. Based on their observations of the weather, as well as talking to their classmates, they...

Green roofs aren't just eco-friendly — they are literally green with trees. Groups learn about the concept of green roofs in order to be able to design one. The groups design a 5,000-square-foot green roof for a fictional apartment row...

Look into the future with a lesson plan on biodiversity and natural habitats. Learners read articles about different perspectives when it comes to planning future development, and decide which angle is the highest priority in a...
