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 lesson plan has clearly described activities, and all of the...

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

Students complete a unit of activities to learn about ocean life as well as improve their math and measurement skills. In this ocean life and math skills lesson, students complete 8 lessons to learn about ocean life and complete...

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...

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

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 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...

Students predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.

Students 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...

Why does Nia's water taste saltier than Trey's if she put more into her cup than he did? Math masters set up proportions in order to compare the mixtures. This task effectively has learners apply the concepts of ratio and proportion to a...

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...

What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the...

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...

Young scholars examine an experiment in which 2 types of commercial fish are fed a new type of fish feed and a commercial fish feed which costs ten times as much. They calculate in the fish grow as well with the cheaper fish feed and...

Students investigate how water is utilized in producing food. In this agriculture lesson, students examine how much water goes into the creation of their daily menu. Students create a new menu that can conserve water and cut their water...

Eleventh graders identify, create and solve word problems involving inverse variation. In this algebra lesson, 11th graders solve problems using direct, inverse and joint variation. They identify problems using these methods.

Students investigate the lives of frogs by completing several worksheets.  In this biology lesson, students discover the life cycle of a frog from tadpole to death.  Students complete frog life cycle puzzle as well as create a...

Students observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...

Students investigate the relationship between volume and mass in different liquids such as vegetable oil, rubbing alcohol and water. They measure the mass of several different volumes of each liquid and then graph the results as well as...

Learners discuss environmental preservation and sustainability and their role in consumption and preservation. After a brief demonstration of how limited our resources are, students determine which natural resources they use most...
