Students create a compost cake. In this gardening and decomposition science lesson, students review and describe the "nutrient cycle." Students create a compost pile, measure and record the dimensions and temperature of the pile, and...

Students are introduced to the concepts of a watershed, stream flow and water quality. This five-day plan is an excellent way to introduce students to the concepts involved. They create their own watershed using a paper bag, water and...

Students identity the components of electron transport system through role play. They explain the role of intermediate energy carriers to the production of ATP molecules. They describe the relationship of electron transport system to...

Students examine the life cycle of the butterfly through literature. In this butterfly life cycle lesson, students listen to a read aloud of Eric Carle's, The Very Hungry Caterpillar, and discuss the life cycle shown in the story. They...

Learners examine a frog's life cycle. In this amphibians lesson, students read a book about frogs and discuss how frogs are born and how they grow.  Learners complete worksheets on the life cycle of the frog, and hold a discussion...

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

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

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...

Students, after observing the elements of a local watershed, explore the need to protect watersheds as water resources for the future. They examine the factors involved with a watershed: geology, ecology, and the effect of man's...

In this rain forest activity, students use different basic math skills to calculate the percentage of Earth covered by rain forests today compared to fifty years ago. They study the effects of how cutting down trees contributes to water...

Students draw and label the four parts of a plant. They describe changes that are part of the common life cycle. Students follow various one and two step directions. They are asked to discuss that they can recall about plants.

Students bag trees to determine the mass of the water given off in the evapotranspiration process.

Learners explore potential issues of a water shortage.  In this water conservation lesson plan, students brainstorm the many uses of water and what life would be like if there was not enough water available.

Fourth graders observe the effects of water on the soil and record those effect by drawing sketches of water erosion and conservation practices.

In this energy flow instructional activity, students will complete 10 short answer questions based on a food web diagram. Then students will review different cycles in nature including the water cycle, carbon cycle, and energy cycle....

In this farming worksheet, students explain what is meant by sustainable development. Students review how rain develops. Students determine how climate effects crops that can be farmed. This worksheet has 4 graphic organizers, 1 graph,...

Play Jeopardy as you review what might possibly be an entire year's high school biology course! The vast variety of questions requires that you read through the slides to make sure that they all relate to your curriculum. You could make...

We can see the result of electricity  but not the process itself. The simulation compares electric circuits to a water tower and water wheel cycle. Young scientists adjust the height of the tower, the amount of resistance, and if...

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.

There is so much to learn about the different cycles, processes, and parts of the biosphere. Using a pretest as a formative assessment to see what your budding ecologists already know is a great way to figure out which important areas...

Using a magnifier, mini marine biologists examine the barbules of a bird feather. They swirl the it into a mixture of oil and water and then re-examine the feather. After the activity, discuss how the oily feathers pose a problem to...

Second in a three-part lesson on rivers, this lesson focuses on the flooding that occurs in riparian locations. First, learners take a look at facts about the Amazon River. They read online materials and fill in a worksheet as they...

First graders compare and contrast water from different sources. After collecting water from various sources, 1st graders create a list of observable properties of the water. Students then pour the water into a filter and observe the...

Third graders explore water by examining a terrarium.
