Fifth graders explore changes in nature. They identify chemical and physical changes in the water cycle, carbon cycle, and weathering. Students explore a chemical or physical change based on a chemical formula. They examine the effects...

Fifth graders discuss the differences between chemical and physical changes. In groups, they complete experiments and discover how a physical chnage can be reversed. To end the lesson, they review the steps of the water cycle and...

Students identify the differences in local soil types and the relationship between soil size and water retention. They are introduced to microenvironmental conditions in ecosystem sustainability.

Students examine the effects of rainfall on different surfaces and discuss water pollution. They review the water cycle and the uses of water in daily lifestyles. Students discuss the effects of soil run off in streams and rivers.

Third graders examine the natural circulation of water from oceans, lakes, and rivers to evaporation into the air, and then to condensation to produce rain falling back to the soil as components of the water cycle.

Seventh graders view Edward Burtynsky's artwork that represents ship breaking. They view images of recycling, the water cycle, rusted metal, and ships to determine factors that threaten the existence of a particular habitat of an...

Learners discover ways to preserve the Earth's resources. In this natural resources lesson, students investigate how many gallons of water the average American uses per day and then total their estimated usage. Learners discuss the...

Students create a model of the birth of a star and demonstrate the stages of the star's lifecycle.  In this star lifecycle lesson, students mix flour and water in a jar to model the birth of a star, then role-play the entire...

Students review the three types of rocks and the rock cycle. They participate in an experiment in which they discover the lithification process of sedimentary rocks. They record and share their observations.

Learners study the Miller-Urey Experiment including its history and criticism.  In this origins of life lesson students repeat this experiment to see how it works.

Pupils have discussions and complete activities about the pacific salmon life cycle and marine parasites. In this salmon lesson plan, students complete activities such as observing sea lice, playing a tag game, and a board game.

Pupils examine the effect of different types of light on the Earth. They discover the role of evaporation and the effects of the sun on the magnetosphere. They also observe different solar phenomena.

Students see that spiders have a life cycle, and reproduce by laying many eggs. We can count by ones, twos, fives, or as many as we want. They make two lists of animals on a chart.

Students investigate relationships between plants and animals and how living things change during their lives. In this life cycle lesson, students split different types of seeds apart to see the beginning life stages of future plants.

Students show their knowledge by choosing the correct answer about solids, liquids and gases. Students also write short answer responses to questions about experiments they have done.

In this oyster culture cycle worksheet, students answer 31 questions about the six stages of the oyster culture cycle. They also answer questions about the oyster business.

Students investigate the various factors that influence the Pacific Ocean and Monterey Bay, California. They watch a video about Monterey Bay and take notes, and conduct research and write a report about a specific organism living in...

Sixth graders create a KWL chart about microorganisms. In this biology lesson, 6th graders create and label a diagram on a microbial mat. They investigate the processes involved in the carbon, oxygen and sulfur cycles.

High schoolers demonstrate the effects of photosynthesis and respiration. They decide which variables to analyze in a microcosm study. They produce a written paper, oral presentation, poster, or multi-media presentation

Learners investigate refraction and reflection of light. In this light lesson, students perform 3 activities to observe light interacting with matter by using a flashlight. They explore refraction using a glass of water and reflection...

Students investigate the affect of non-native species on Pacific Salmon. In this non-native species and Pacific Salmon lesson plan, students participate in a competition and habitat loss game. They play the game in groups, while...

Students work together to identify marine debris. They explain the effect of the debris on various ecosystems. They draw different types of ocean currents as well.

Students, in groups, develop their hatcheries, working cooperatively in its design and construction. The lessons begin with the introduction to Artemia as a primary food source of many aquaculture species during their larval stages.

The "Engage" section of a wetlands lesson plan asks young ecologists to examine a wetlands poster. You can easily find one online and display it using a projector. Pupils immerse a piece of sandstone and a piece of granite in water to...
