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 explore and analyze weather conditions, climates, compositions and characteristics of the atmosphere and weather patterns. They explain in detail the water cycle and its relationship to weather patterns. A lab experiment is...

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...

Second graders discuss the geologic rock cycle and work with their group to simulate creating a sedimentary rock. They conduct an experiment that demonstrates the sedimentary process and draw the steps of the rock cycle.

Students understand the sea ice cycle and can explain its stages. In this Sea Ice lesson, students play a game to identify types of sea ice. Students answer critical thinking questions about sea ice. Students complete a sea ice worksheet.

Students construct a working model of a turbine and explain how water generates power. By the end of the lesson, they list the effects of Kingsley Dam on people, plans, and animals -- both positive and negative.

Students explore renewable and nonrenewable resources. In this ocean preservation activity, students use KWL charts to understand ways the ocean is important to our daily lives. Students create a poster or wirte a letter to someone...

Learners 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.

Middle schoolers discuss the importance of recycling and preventing pollution. In groups, they complete mini-studies on various environmental issues and evaluate different consumer products. They use global warming data to determine...

Students understand the purpose of an aquifer. In this aquifer and groundwater lesson, students build a model aquifer find its relationship to water usage. Students record observations as they build the layers of the aquifer.

Little learners examine a map of the southwestern United States and identify the Sonoran Desert. They locate different cities and rivers, determining whether or not each is found within this special ecosystem. A student handout is...

Pupils identify the processes involved in the water cycle. In this math lesson plan, students explain what civil engineers and hydrologist do. They watch a video about flooding in Texas.

First graders investigate the changing states of water.

Students develop awareness about the water cycles. They identify the watershed in which their school is located. They explain the role the schoolyard plays in the watershed.

Students use plastic bottles to create terrariums and plant Venus Flytraps. They observe the plants and the terrariums for illustrations of the water cycle and species' adaptations to a specific environment.

Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science lesson, 6th graders complete 6 experiments about chemical and physical changes. Students examine the processes of...

Students explore botany by participating in a calendar class activity. In this plant observation lesson, students examine a diagram of a Brassica plant and identify its anatomy before planting their own seeds and viewing the changes over...

Students write books about trout, completing one page per life stage.

Learners discuss places they have been where the air seemed hard to breathe. They discuss if they could "see" the humidity or smell. Students discuss ways this might relate to the fish in the aquarium. The teacher introduces pH and how...

Third graders study the 3 main types of rocks: igneous, sedimentary, metamorphic. They examine samples of these types of rocks and discuss ways to tell what kind of rock each is. They take notes and draw pictures in their science...

The fifth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program defines dead zones and how they form. Pupils then examine data from the Gulf of Mexico to determine dead zone formation.

Small but mighty! Learners explore the role of microbes in a healthy ecosystem. An engaging lesson asks pupils to design an aquaponics system that demonstrates that healthy microbes are necessary to maintain the ecosystem.

Why do scientists rely on drawings rather than just photographs of their research studies? The lesson introduces drawings of microscopic organisms and the importance of accuracy. Young artists draw organisms and learn why focus and...

In this photosynthesis worksheet, students answer 18 questions in a combination of multiple choice and short answers including the completion of a table.
