Students test samples of water to determine how a chemical water softener affects water's ability to form suds. After collecting their data and analyzing their results, students answer follow-up questions about their lab.

Students work together to research water quantity, quality and safety standards. They complete a lab to discover how to use the water from an air conditioner. They write a paper to show their findings.

Sixth graders complete a lesson on the properties, types and amounts of water on Earth. In groups, they travel between stations to identify water resources in Illinois and pollution sources. They complete the lesson with a field trip...

Young scholars discuss the benefits of water conservation. Given a data sheet, they document their water usage over a specified period. Water usage data is graphed and analyzed. Students discuss ways in which they can conserve water.

Eighth graders analyze different water samples given to them by their teacher.

Learners estimate the amount of water that can be found in its various forms including oceans, lakes, glaciers, rivers, etc. They view a demonstration about water distribution and discuss flash flooding safety precautions.

Fifth graders examine what contaminated water looks like, and how it becomes polluted. They examine a teacher demonstration of water is not polluted but does contain rocks and other things that do need to be cleaned out before drinking...

Students work together to design their own experiment to test developed hypothesis about the minerals in water. As a class, they discuss the main components of water quality and describe the chemistry behind the hardness assay. They...

Fourth graders write at least two ways to clean the water and two ways to prevent pollution with appropriate guesses, striving not to create any more pollution in the water. They understand how pollution affects water as well as the rest...

Pupils research the quality of water in a regional lake of West Bloomfield in the past and present. They compare conditions of the lake, past and present. They then give examples of local and regional human activities that may have had...

Students hypothesize what happened to the missing water. In this chemistry lesson, students test their hypothesis by designing an experiment. They record observations and report findings to class.

Students observe a model of a waterwheel to investigate the transformations of energy involved in turning the blades of a hydro-turbine into work. They work as engineers to create a model for a new waterwheel while considering resources,...

In this environment worksheet, students read an article about extreme weather conditions and mapping it out. They respond to 10 multiple choice questions about what they read. Then, students explain how droughts can occur and the...

An informative lesson focuses on heavy metal contamination of environments. Classes read about, discuss, and answer questions pertaining to sources of heavy metals in the environment. To finish the 35th installment of 36, individuals...

The four cycles in Earth's biogeochemical system are covered in this worksheet. Science stars fill in the blanks or define vocabulary terms pertaining to the hydrologic, carbon, nitrogen, and phosphorous cycles. This resource provides a...

Discuss different sources of energy and how much greenhouse gas each might emit. The six sources are then ranked according to emissions from greatest to least. Finally, the true cumulative emissions are revealed to show the class how...

The surge in human population in the last 2,000 years, due in large part to better health care, has brought a surge in the demand for resources and in pollution. The graphics, photographs, and real-life examples in a thought-provoking...

Learners investigate how solar energy is converted into heat in part two of the 10-part Discover Your Changing World series. They build and test homemade solar cookers to boil water and cook rice. Pupils consider the impact of heat...

Why does it get so hot inside of our cars in the summertime? The greenhouse effect! Lab groups experiment to see what happens to an ice cube enclosed in a jar and placed in sunlight as compared to an ice cube outside of the jar. They...

What is more important: building a new school or preserving a nature reserve? Keeping a natural area clean or providing clean drinking water to a city of millions? Young scholars weigh these questions—almost literally—using an...

Seismologists use the direction and arrival times of p waves and s waves to determine the distance to the source of an earthquake. The engaging lesson has students line up to form human waves. Through different movements when attached,...

Can a coral cure cancer? Take seventh and eighth grade science sleuths to the underwater drugstore for an investigation into emerging pharmaceutical research. The fifth installment in a series of six has classmates research the wealth of...

Sediment samples from the ocean bottoms tell scientists about climate change, pollution, and changes in erosion for the area. Groups of learners focus on sediments and their movement through water. During a hands-on activity, they...

Convection currents aren't just a bunch of hot air. The second of five lessons in the Solar Updraft Towers unit focuses on energy transfer and convection currents. Young scientists watch six demonstrations that illustrate how warm air...
