In this science worksheet, students answer 14 questions about respiration. For example, "Cellular Respiration starts off with..."

Students determine

While this resource does not provide problems for chemistry learners to solve, it outlines skills that they should have and concepts that they should grasp. Topics include thermodynamics, periodicity, redox equilibria, transition metals,...

Students observe water birds feeding at a local wetland, record what they see, and construct an appropriate menu for a "Waterfowl Cafe." They also play a "flocking" game.

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

Students develop an understanding and appreciation of water purification techniques and their implications for health maintenance.

In this drinking water worksheet, students complete a crossword puzzle given 23 clues about drinking water purification, water content, contaminants, and softeners.

Learners examine biodiversity and interrelatedness concepts.  In this ecology lesson plan students go on a field trip and fill out a data sheet. 

In this absolute time worksheet, students define radiometric dating, tree rings and varves as means to measure absolute time. They are given information about each of these methods of dating.

Ninth graders explore how electricity is created and distributed through alternative production methods. Students participate in hands-on activities, research, lecture based instruction, and CD ROM resources.

Students investigate what dissolved oxygen is and why it is important to aquatic life and what factors influence levels of dissolved oxygen in a lake. They study how to use MS Excel to make charts to show trends and correlations.

Instructional module focusing on the carbon cycle. Discussion includes the biological and geological components of how carbon moves through the atmosphere, lithosphere, and hydrosphere. Site also includes an interactive practice quiz and...

Video talks about the carbon cycle and uses a computer as a metaphor to show how the cycle can be disrupted by climate change. [3:55] Includes a short quiz and a list of additional resources to explore.

This lab uses a robust model of the carbon cycle to give students an intuitive sense for how carbon circulates through the atmosphere, biosphere, oceans, and crust. It allows them to experiment with how human input to the cycle might...

Illustrated interactive explores the 12 steps of the carbon cycle that show how carbon moves through the environment.

A lesson plan with downloadable handouts and teacher instruction sheets where learners learn about the carbon cycle by simulating it in a game format. There are two rounds of the game where they first look at the pre-Industrial...

Learn about the element carbon and its importance on the Earth's atmosphere and sustainability of life on the planet. Additionally, understand the role the carbon cycle plays in global climate change over time.

A comprehensive introduction to the carbon cycle. The cycle of atoms between living and non-living things is known as a biogeochemical cycle. The most common of these are the carbon and nitrogen cycles.

Useful introduction to the carbon cycle with a diagram and a discussion of the effects of carbon dioxide on the greenhouse effect and global warming.

Resource to help learn about the carbon cycle.

In the following lesson students learn how geologists locate fossil fuels by using a straw to extract "core samples" from a model that has different layers. Student sheets are provided in English and in Spanish.

Article explaining the importance of carbon as the basis for life, carbon dioxide's role in photosynthesis and respiration, carbon in the ocean and lithosphere, the impact of human activities on the carbon cycle, carbon that seems to be...
