You don't have to travel far to learn about rocks, just step outside, pick up a stone, and begin investigating. After taking a class walk around the school grounds collecting rocks, young scientists practice their skills of observation...

Students explore the cycles of an ecosystem.  In this environmental science instructional activity, students work in groups to research the nitrogen cycle, the water cycle, or the oxygen-carbon dioxide cycle. Students prepare a...

Fourth graders investigate the life cycle of a tree by researching the Internet.  For this plant life lesson, 4th graders observe The Life of a Tree website and discuss the life of a tree from sprout to death.  Students create...

Students explore oxygen properties by conducting a cell experiment in class. In this respiration lesson, students discuss the process of breathing and how oxygen is inhaled before carbon dioxide is exhaled. Students utilize yeast, water,...

In this cellular respiration and photosynthesis instructional activity, students read through the presented material and draw an illustration of the production of ATP. Students answer several short answer questions about the production...

Students explore the ecosystem by conducting a ziploc bag experiment. In this recycling lesson, students identify decomposer organisms in our environment and how they speed up the recycling process. Students utilize a ziploc plastic bag,...

In this matrix reactions worksheet, students fill in the blank about the process of glycolysis. Students also draw an organelle- mitochondrion and label the parts with the given names.

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.

For this metabolism test review, students define several terms. Students write balanced chemical equations for aerobic cellular respiration. Students complete several multiple choice questions.
