Going in Cycles: The Life of an Aluminum Can

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,...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

After reading about the history and recycling of paper, creative crafters collaborate to think of a new process for making recycled paper. A complete teacher's guide and student worksheets are included. There is no written procedure for...

Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

Curious physical scientists follow a lesson on the properties of water with this lesson on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an enriching...

Observe the stages of the water cycle by completing 3 activities. To help understanding of the water cycle your students can observe evaporation, the formation of frost, vapor and water and the process of distillation which is used to...

A woman had a job crushing cans at the recycling plant; it was soda pressing. Video focuses on the ways our environment recycles, including the water cycle, carbon cycle, nitrogen cycle, and the phosphorus cycle. It also describes the...

A video explains both positive and negative feedback loops including body temperature, ripening fruit, and diabetes. An accompanying worksheet helps organize scholar's notes. 

What types of water qualify for recycling and how does the recycling process work? The eighth lesson in the 10-part series exploring Fresh Solutions presents both the financial and water savings associated with emerging recycling methods.
