Students explore water properties by conducting a class experiment. In this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of salt...

Here is a great hands-on activity that should lead to a greater understanding of salt water, why the ocean is salty, and how ocean waves are formed. This terrific, old-school instructional activity has clearly described activities, and...

In this freshwater on Earth worksheet, 8th graders color and complete 2 graphs as described in the given information. First, they color the non-drinkable water portion red and the freshwater portion blue in the top graph. Then, students...

Field trip! The class will review what they know about organisms that dwell in freshwater ponds, then trek down to the old water hole to collect specimens for examination. This includes several web links, useful tips, and an excellent...

Fresh water is a precious resource. Most kids don't realize how little of the water on Earth is actually drinkable. This lesson will help to illuminate them on this important topic. They discus the ratio of water to land, where most...

Here's a powerful demonstration that makes the point that it is everyone's responsibility to conserve water and protect the earth's limited supply of fresh water.

Students investigate the amount of fresh water on earth and which water can be used for consumption. For this fresh water lesson plan, students calculate the amount of fresh water that can be used for consumption on earth. They use a 5...

Groundwater is an essential natural resource, not to mention a fascinating topic to study. Here is a series of twelve amazing lessons on the water source and how we use it in our daily lives. Concepts require higher math and physics...

Your young apprentices build a function describing the percent concentration of salt in a brine. The rational function is then related to the parent function, y= 1/x, and graphed. Finally, the apprentices predict the amount of fresh...

The goal of this collection of lessons is to make middle schoolers more aware of the ways in which they are dependent upon water to maintain their standard of living. Learners compare water use in Lesotho to water use in the United...

Students study low tides and how to calculate for fresh water. In this ocean science lesson plan, students pretend they are stranded on an island and must calculate low tide in order to source the fresh water aquifer. Students calculate...

Water is the focus of an interdisciplinary unit that brings awareness to its daily use around the world and the importance of conservation. Worksheets challenge scholars to match words and definitions, trace, complete a maze, and solve a...

Students compare quantities of water. In this water lesson students examine the hydrologic cycle looking for the amount of fresh water that is available. Students use information from charts and diagrams.

Students examine effects of an oil spill on birds and animals that inhabit marine or freshwater ecosystems, and simulate procedures used by rescue workers who rescue and rehabilitate birds and other animals coated with oil.

In this graphing worksheet, students examine a prepared bar graph and record which habitat their chosen animal lives in: desert, city, forest, ocean, prairie, or fresh water. There are no directions but it appears that a class could use...

Young scholars describe limitations of fresh water resources on ships at sea. They realize the value of fresh water on the ocean and around the world. Students gain a knowledge of the process and economic cost of desalinization.

Pupils discover the percentage of an iceberg that is above and below the water surface. They compare salt water icebergs and fresh water icebergs and if they behave the same of differently. They work with their lab group to perform...

Learning to read data tables is an important skill. Use this resource for your third, fourth, or fifth graders. Learners will will study tables of fish collection data to draw conclusions. The data is based on fish environments in the...

Subtracting negative numbers can be confusing to your middle schoolers. Here, they are able to draw a number line and put their answer in sentence form to check their understanding of negative numbers. 

Students experiment to determine the effect of light on cyanobacteria movement. They graph the data of the experiment for further analysis. They watch a time-lapse video of cyanobacteria motility at a NASA website.

Third graders read the article "Blue Claw," discuss crab migration, and look at a map of the Hudson River. They complete a worksheet where they must use subtraction to determine the distance migrating crabs travel.Web links, article, and...

Learners study the water cycle and how the sun is an important factor.  In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

Students explore features to consider when designing a scientific study. In this science research lesson, students examine different methods of data collection and consider which method would be appropriate for determining how many types...

Students explore reasons for varied salinity in bodies of water. In this geographical inquiry lesson, students use a variety of visual and written information including maps, data tables, and graphs, to form a hypothesis as to why the...
