Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

Fifth graders study the impact of human activity on water quality and on the ecosystems of Earth. After a discussion on the various ways that water can be polluted, groups of youngsters get together to figure out the best way to clean a...

Young scientists investigate the water cycle through a lettuce seed experiment. For this experiment, learners plant lettuce seeds inside of a ziplock bag in order to create a small greenhouse. They observe condensation and precipitation,...

Students examine where water is found in the world, how we use it, and the various forms it takes. They observe the refraction of light through a prism, record the day and night sky over a week's time, and create a topographic model of...

Students examine the causes and effects of soil runoff. In this environment lesson, students look at ways in which soil runoff is controlled. Students then play a game  and discuss how the Peace Corps deals with soil runoff in...

Here is a fine lesson for fifth graders that will give them an idea of the variety of impacts that human-introduced pollutants have on the environment. After an initial class discussion and teacher-led demonstration, pupils brainstorm...

Auntie Litter is here to educate young scholars about water pollution and environmental stewardship! Although the 15-minute video clip is cheesy, it's an engaging look at the water cycle and conservation. Learners start by illustrating...

Young scholars determine a watering schedule that promotes healthy grass growth. In this plants and natural resource conservation lesson, students plant grass seed in liter bottles and follow two different schedules that include "more...

Students discover what are the components of soil. They examine how it is formed and it's importance. They engage in garden activities and processes. They hold a handful of garden soil and describe what they see. They take a...

Students are introduced to the components and importance of the water cycle. They are shown how groundwater moves using a model. Students list 9 places on earth where water is found. They define the terms cycle and water cycle.

Students will be able to identify the characteristics of healthy soil and unhealthy soil.Take the class outside to an area of thick grass near trees, if available. Compare the clothes people wear to the thin cover. Discuss the reasons...

Learners examine how effects of farming practices in the early 20th Century contributed to severe soil erosion of a large portion of the North American grasslands.

Students examine how water is treated prior to becoming available for human consumption. In this water treatment lesson plan, students conduct an experiment in which they filter water. Students formulate a hypothesis, test, analyze data,...

Learners identify the different types of water and explain in what proportions they exist on Earth. They identify and correctly label the parts of the water cycle and how these parts interact with each other. Students identify the...

Students examine the Dust Bowl and the effects of farming practices in the early 20th century. They read a handout, and conduct and discuss two experiments simulating soil erosion.

Students participate in a hands-on experiment to compare how water and soil erosion affect soil and grass. They determine how slope affects erosion and how terracing affects erosion. They write a paragraph summarizing their data.

Students discover how water moves through different types of soils. In groups, they use the same sample from a previous activity and empty it into a milk carton in which they have layered with cheesecloth to determine the percolation...

Fifth graders investigate how humans pollute the water supply with a number of different contaminates. While working in small groups they examine screening, sedimentation, filtration, and chemical treatments as methods of water treatment.

Second graders observe images of prairie ecosystems and discuss the needs of living things. They create a prairie habitat in a closed jar to observe the water cycle and plant growth.

Students develop and test a hypotheses through collecting and recording water quality data. They perform their tests outdoors in a location with a safe stream and easy access for students. Their various experiments involve the entire...

Fifth graders engage in some activities that will help them to identify erosion and explain the causes of erosion. They also look into ways that humans can slow the process of erosion in some cases. After a teacher-led demonstration,...

Pupils conduct experiments demonstrating soil erosion and the benefits of conservation practices. Working in groups, they use topsoil and sand in shallow boxes as models to examine the effects of water on soil and sand with and without...

Learners are able to describe the importance of wetland vegetation. They describe the impacts human activities have on water systems. Students compare and contrast the effect of different soil types on water filtration.

Fifth graders observe and record what happens when household products are added to a tank of water to depict water pollution. They brainstorm ideas of how to clean the contaminate out of the water before watching demonstrations of...
