Sedimentation Lab ActivityAdam Fox
7th - 12th
Students predict how sediments in a water column will settle. In this earth science lesson, students examine the layers of sedimentation. Students are given sediments to place into a column of water and observe how they settle. Students expand this knowledge to the running water of a river.
The Water Cycle
Your class sets up a mini water cycle model to examine the process. Then they watch an animation, following a water molecule through the cycle. A well-developed lab sheet guides learners through the lesson plan and a PowerPoint presentation supports your direct instruction portion.
Density Separation of Local Sediments
Seventh graders investigate the density of local sediments. In this earth science lesson, 7th graders compare the densities of known material to that of an unknown sediment to determine its composition. They record observations in their data table.
Water Awareness Portfolio Instructions
Students participate in a water awareness portfolio. In this water conservation instructional activity students create a portfolio to help make them aware of current water conditions.
Water is the best drink in the world; unfortunately it can be toxic without being filtered prior to consumption. Get those kids thinking about the wonders of water filtration with a fun and engaging activity. They begin by brainstorming why water can make them sick and different ways to clean water to make it drinkable. They discuss chemicals and other substances found in drinking water and then make a small water filtration system from water bottles and coffee filters.
Clean Clear Water
Students explore the waterways in their community as habitat for many birds, fish and bugs. They discuss water pollution, watch a video, and observe the filtration of water using a two liter bottle.
How Much Salt is in the Gsl Water?
Fourth graders study the water cycle and the different processes that are involved, like precipitation, evaporation, etc. They conduct an experiment observing the water cycle in action and write a hypothesis, observations and conclusions. They draw a picture that shows how the water cycle works.
Through a thorough examination of water sources and samples, the concept of watershed management and human effects on the water supply is explored in depth. Young ecologists will look at the pH of several water samples, as well as the nitrate, phosphate, and chloride levels and the presence of soap, fertilizer, gasoline, and pesticides. Designed for a specific watershed in North Carolina, you may wish to adapt the data to reflect your local watershed to make the activities more relevant to learners.
Water Cycle (Grades 2-4)
Students demonstrate their understanding of the water cycle and how it effects the environment by graphically depicting and describing the water cycle.
Water, Water Everywhere!
Students brainstorm on ways they use water, and where water comes from. They view video, Down the Drain, to gain specific facts about water use, properties of water, problems of water and the water cycle. They perform a lab activity demonstrating
Water, Water Everywhere and Not a Drop to Drink
Students discuss the importance of taking care of their water supply so not only they can use it but generations in the future. In groups, they examine a real pollution scenario in which a sewer overflowed into the ground water. They use the Internet to research how water is tested and what they can do to conserve the amount of water they use each day.
