New! Sedimentation Lab Activity
7th - 12th
Students predict how sediments in a water column will settle. For 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.
Where Did The Water Go?
Here is a terrific earth science lesson plan on the water cycle that's designed for grades two to five. In it, understanding of the water cycle will be enhanced. The lesson plan focuses primarily on evaporation, and what happens to the water vapor once it's back up in the atmosphere. This fabulous, 8-page plan has everything you need to implement it with your class. Terrific worksheets, web links, and detailed activities are all here for you.
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.
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.
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.
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.
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.
Winter Advisory: The Effect of Salt on the Freezing Point of Water
Why do we salt roads when they have ice on them? Middle school physical scientists experiment to find out that salt lowers the freezing point of water. This classic lab experiment has a practical application and is also designed to meet Common Core standards for literacy in science.
Can Nutrients in Water Cause Harm?
Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how important it is to protect freshwater bodies. This can be used as part of the water unit, or alone as a instructional activity on water pollution.
How Can We Find Out What Is in Water?
Using paper chromatography, water watchers discover that several substances might be dissolved even though they aren't visible. For this case, you will prepare a mixture of three different food colorings for them to experiment with. A brief discussion follows. This lesson is part of a unit on the properties and the conservation of water, but stands alone well as a lesson on separating mixtures for a physical science class.
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
