Compost and Composting Experiments

Roll up your sleeves and get a little dirty with this elementary and middle school compost lesson. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and you're ready...

Whether you are teaching environmental science in junior high or studying recycling in kindergarten, there is something for all in this set of lessons designed for environmental education. The 110-page packet comes with tips for...

Build a place for the plants. Using information learned from the previous lesson in the unit, learners design a lunar plant growth chamber and build a paper model of it. Given strips of paper that represent different sizes of planting...

You don't have to be a scientist or even out of high school to contribute to scientific research. In the 12th lesson in the series of 21, scholars use this opportunity to add to the growing body of scientific knowledge and consider the...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Some scientists argue that air pollution now causes more deaths than smoking. The second unit in a six-part series focuses on air quality. Scholars learn what's in the air, how clean the air around their school is, and what they can do...

Young scientists create a compost bag, predict changes, and after one month, examine the bag to observe the changes that have occurred.

Create the perfect conditions for osmosis. Young scholars use a microscope to observe plant cells exposed to distilled water or sodium chloride. They observe how osmosis creates turgid or plasmolyzed cells.

If any of the limiting factors in an environment change, both animal and plant populations also change. The video explains two different models of growth and the impact of limiting factors. It highlights the carrying capacity of an...

Use indirect measurements to monitor metabolic activity in plant cells. Scholars understand that cells with a higher metabolic rate have a higher concentration of catalase enzyme. They use this information to compare metabolic rates of...
