Students build a water filtration system. In this water quality lesson, students work in groups to construct water filtration units that can purify contaminated water. This lesson is part of a larger unit on water quality.

Sixth graders explain how soil and plants effect contaminated water in nature.  In this filtration lesson plan, 6th graders work in groups to test biofiltration units. Students determine which biofiltration units work best and how...

Students examine the possible ways to recycle, reuse, and re-imagine products and objects in order to reduce pollution and waste on our planet. In this 100 things you can do to save the planet instructional activity, students take three...

Young scholars identify the different stages in the water cycle. In this environmental science lesson, students research about different water pollutants in watershed. They describe ways to purify water.

Students investigate what is known as the Greenhouse Effect. They begin to explore what some scientist think is the nature and fundamental causes of this problem. Students are able to give suggestions for alternative causes of global...

Students participate in an experiment to define a parts-per-billion solution. For this ecology lesson, students select a second substance to create a parts-per-billion solution and observe and record their results. Students work in...

Learn about wastewater and recycled water with a science reading activity. After learners finish a two-page passage about conserving the water supply, they answer six comprehension questions about what they have read.

How does dirty water get clean enough to drink? After viewing a PowerPoint that outlines the process water goes through at a water treatment plant, groups work together to design a chlorination chamber for a treatment plant.

How diverse are the benthic organisms found in local streams? Using the information learned in previous lessons on identification of macroinvertebrates and on calculating stream index values, groups determine the health of local...

Environmentalists turn into engineers! Your class explores the perspectives of an engineer and water keeper, including the necessary steps that are taken in order to build a water treatment facility.

Here's a lesson that's not for the birds! Scholars design and build packaging for soda cans that is environmentally friendly. These packages must be durable, easy to carry, and have no environmental impact.

Using an Equity Impact Review (EIR) tool, developed by Washington state's King County to "identify, evaluate, and communicate issues of equity when making a decision," class members design a GSI program for two Seattle neighborhoods.

How do we protect crops and protect the environment at the same time? Using reading materials, learners explore the history of the use of pesticides and biocides. They create a timeline and then explore the current practices.

How much plastic do people use? Class members identify how plastic is involved in their daily lives by looking at food packaging either at a grocery store or at home. Learners view statistics for the amount of plastics found on a beach...

Eggshells and seashells have a lot in common. Learners use the similarities to conduct an experiment that models the effect of ocean acidification on marine animals. Using varying levels of acidic liquids, pupils make observations on the...

What's the best way to collect all that trash? A culminating activity has scholars use the knowledge and skills from the unit to design a solution to the plastic trash island problem. They use 3-D pens or a 3-D printer to build models of...

What does a beautiful sunset have to do with the atmosphere? An inquiry-based lesson has learners make observations about the visibility and color of the sky during different time periods. They then relate their observations to...

Elementary kids read and color the story of Willy Wetsworth, a drop of water, as he describes the journey that he and his friends take to provide fresh water to houses. He tells his story to Martha Merriweather, a little girl, and...

The quality of a watershed has a direct impact on the community it services. Learners study their own watershed using a topographical map. They recreate the watershed components using colored pencils to track the upstream and downstream...

This unit is so cool, you won't be able to "kelp" yourself! Intended for all grades, this science and activity guide for teachers offers a unique opportunity to understand kelp's role as a valuable ecological resource. Teachers and...

Study the ways that humans have impacted the environment, particularly the spread of plastic waste. After watching a short film about the Laysan albatross population, learners complete a worksheet and research other ways that plastic...

Searching for an eccentric way to enhance lessons on ecosystems while ensuring pupils remain creative and motivated? Upon viewing The Lorax by Dr. Seuss, designated groups design and construct a pop-up book that...

With a piece of plastic here and a piece of plastic there, here a piece, there a piece, everywhere a piece. Teams go on a field trip in order to document the locations and kinds of plastic trash in an area near them. The eighth...
