From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space...

In groups, young environmentalists investigate water samples that are contaminated with different types of pollutants. Each group presents their findings to the class and fills out the "Types of Pollutants Chart." This lesson is meant...

Young scientists investigate the water cycle through a lettuce seed experiment. For this experiment, learners plant lettuce seeds inside of a ziplock bag in order to create a small greenhouse. They observe condensation and precipitation,...

Learners use litmus paper to begin to discover the qualities of acids and bases. They learn about pH by testing clear liquids for acidity with purple cabbage juice as an indicator. The video Streamkeeper, with Bill Nye, and other video...

In this environmental studies worksheet, learners create a data table to discover how much water each person uses on a daily basis and what it is used for. They complete a post activity to make and test solutions for pollution using a...

Here is a fun little exploration of the potential energy potential of falling water. Learners drop water from various heights using a straw, and they analyze the diameter of the splash. Pair this with two more activities of the same...

Super scientists tests the toxicity of water using radish seed bioassays. Over the course of five days, scholars observe the germination process of several radish seeds, looking closely at their roots to determine the level of toxins...

Why do scientists rely on drawings rather than just photographs of their research studies? The activity introduces drawings of microscopic organisms and the importance of accuracy. Young artists draw organisms and learn why focus and...

Students sample goodies from an unseen ocean floor and try to accurately describe their composition. This simulation helps students explain the limitations of sampling and the problem of obtaining representative samples of sea floor...

Students explore the water cycle. In this earth science lesson, students observe and measure water in a closed container and in an open container. Students record their observations and compare their sets of data to draw conclusions...
