Students develop an understanding and appreciation of water purification techniques and their implications for health maintenance.

Second graders help to prepare a model of the water cycle before the conduction of this experiment. They use the model in order to observe changes that happen to water when it changes states of matter.

Students investigate the concept of erosion by water in a problem solving activity. In small groups, they are assigned either sand, potting soil or rocks to construct a mountain that will hold up to a sprinkler can of water dripping on...

Students use oranges to informally explore decomposition, dehydration, fermentation, the water cycle, bacteria, yeast, food webs, the needs of living things, and physical vs. chemical change over a period of three or more months.

Students in groups, map quadrants of the area around the school and make predictions about the direction of waterflow and zones of accumulation that will occur when it rains. Then when it does rain they check to see if their prediction...

Students examine the habitat and life cycle of a butterfly. In this early childhood lesson plan, students identify the parts of a butterfly, as well as the stages of the butterfly life cycle. Students also plant a garden in which they...

Students identify the stages of the salmon life cycle. In this fish instructional activity, students experience first hand what it would be like to be a returning salmon attempting to identify a home stream by smell.

Students chart how milkweed bugs grow and change.  In this growth and life stages lesson, students read two stories and discuss how and why things grow.  Students brainstorm what can be measured about humans, review and discuss...

Middle schoolers demonstrate how water flows by building a human watershed using themselves. In this ecology lesson, students compare and contrast point-source and non-point source pollution. They write what they have learned from this...

Students analyze the weather patterns in Namibia. They create a graph of the yearly temperatures and use the internet to gather information. They discuss how the weather goes in cycles in the area.

Learners participate in a series of experiments to learn about plate tectonics and the different materials of the Earth. In this plate tectonics lesson plan, students use eggs, water, beakers, paper, and more materials to learn about the...

Students study the interrelationships of organisms and their environments. They study ecological communities and determine what is necessary for survival. Students discuss and answer questions concerning a group's biome, habitat, food...

Students learn along with Ms. Frizzle's class. In this Magic School Bus lesson plan, students get a bugs-eye view of the flower world and find out how seeds are created, how they travel, and how they grow into plants.

Students check the weather on the web site, draw what they see on the calendar (sunny, cloudy, rainy, snowy) and look outside to see if they think the weather on the web site is correct.

Students explore how the angle of sunlight affects the Earth's temperature and seasons and then apply this understanding to their local situation.

Learners explore the concept of "spin" and discuss how politicians use spin to sway public opinion. A leading American politician is selected and talking points that exemplify the main idea of this lesson are shared with the class.

Students illustrate the adaptation and co-evolution of organisms. They examine set up an experiment to determine the effect of adding the Rhizobium bacteria to a group of legume seeds.

Students are introduced to the basic principles of atmospheric pressure. After watching demonstrations, they discover the capability of air pressure and how it affects weather. In groups, they use an inquiry template to solve different...

Students map connections among raw materials. In this environmental stewardship instructional activity, students design strategies to minimize the use of raw materials and discuss how to use more sustainable materials.

Students observe the various living things they can find outside their playground making sure to look both on the ground and in the air. They develop a large poster Venn digram, as a class, of plants and animals that live in the air, on...

Sixth graders research the average temperatures of different places on Earth. In this earth science lesson, 6th graders explain how the sun's heat cause ocean movement. They discuss how temperature change affects the weather we experience.

Students explore what effects improper waste disposal and water pollution have on the water cycle. They explore how philanthropic acts can help protect the water cycle and keep our water and planet clean.

Students examine the relationship between particle size and rate of water flow through soil. They collect soil samples, make predictions, conduct a water flow experiment, analyze the data, and answer conclusion questions.

Second graders define condensation and evaporation. They identify and describe the steps in the water cycle. They ask questions to end the lesson.
