Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

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...

Third graders investigate the life cycle of the Monarch butterfly. They experiment with various tools to simulate the mouth parts of insects, conduct research, record their observations of butterflies hatching, write a play, complete...

Students identify the elements of natural disasters and gain an understanding on how the media influences people's responses to disasters. For this natural disaster lesson plan, students study the impact of natural disasters, and the...

Students 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.

Learners explore the ecosystem and food chain by researching Pacific Salmon. In this fish habitat instructional activity, students discover the life cycle for salmon, where they spawn and what they eat to survive the harsh elements....

Students learn about the biological carbon cycle. In this carbon cycle lesson plan, students access the web site and mouse over the diagrams to follow the carbon cycle. They read about what happens to humans and plants during this cycle.

First graders identify the sun as a source of heat and light. They identify features of houses that help keep use sheltered and comfortable throughout daily and seasonal cycles. Students are told that summer is the best season to...

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...

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...

In this outcome science 4 worksheet, learners apply scientific knowledge to answer and calculate a variety of questions. Students research the answer to several questions using the websites suggested.

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...

High schoolers participate in an activity in which they demonstrate how the evaporations of water from the oceans results in fresh water in the form of rain. They create a saltwater solution in a flask and boil the water until most of...

Students observe a demonstration on the role of thermal conductivity in heat transfer.  In this thermal conductivity lesson plan, students design and conduct an experiment to compare the thermal conductivity of four substances....

What is water worth to you? The answer probably depends on many different variables. Learners explore the value of water in space and what it takes to transport the resource to locations in a galaxy far far away. They then consider...

Students identify and interpret that leaves provide food for new trees and plants. Students cut out leaves and glue them on the appropriate number on included worksheet. Students collect different types of leaves and make leaf rubbings....

Students explore the different types of pollution. they conduct experiments using dye mixed with tap water to measure the levels of dilution. They discuss at what point the dye (pollution) would be diluted enough to be safe to drink.

Fourth graders examine the interdependence of the oxygen and carbon dioxide cycle in an ecosystem through a laboratory investigation. After a lecture/demo, 4th graders complete the lab in groups.

In this science activity, students use the key code on the right to unscramble each of the scientists. They also match each of the scientists found to their correct description.

Students articulate a possible relationship between arsenic and gold deposits in a written statement using data to substantiate the relationship they describe. They use real data to determine the source of the arsenic in the drinking...

Students explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...

Young scholars explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.

Students discuss and evaluate the use of the Yin and Yang symbols in Chinese history, making connections to current trends in Chinese culture. Emphasis is placed on small group discussions.

Students explore how water and waves erode the earth. In this erosion lesson students determine the processes of wave erosion and building.
