When it comes to the carbon cycle, the sky really is the limit. The lesson begins with observing a closed ecosystem in a bottle. Then, scholars discuss and answer questions on the carbon dioxide and oxygen cycles. 

Students construct their own diagrams outlining the pathway of carbon and oxygen in our atmosphere. They listen to a lecture on the carbon cycle while drawing an example of the carbon cycle on the board. Students comprehend that CO2 is...

Learners are shown how temperature affects dissolved oxygen and they create a graph showing this relationship. They think about the adaptations of animals to live in different water temperatures. Students test four different water...

Students are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...

An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

Encourage peer collaboration and assist with the creation of visual aids to identify carbon, water, and nitrogen cycles as your class learns more about nature. They discuss relative information, create a visual aid...

The carbon cycle isn't a bike which produces carbon and this lesson explains why. Through reading and discussion, groups of pupils create visual explanations of the four parts of the carbon dioxide oxygen cycle. Activities...

Students are introducced to how respiration and photosysnthesis cycle carbon through ecosystems. They read background information that describes the role of the Sun as Earth's ultimate energy source and explains how the energy...

Students are presented with the question, "Do plants that grow underwater use oxygen?" They create an experiment to test the presence of dissolved oxygen in the water using provided materials. Student experiments include a control jar as...

Students demonstrate comprehension of the energy sources of various cycles by completing mini stories. They demonstrate analysis of words by defining individual word parts and combining them to form definitions. Students demonstrate...

What impact do humans have on greenhouse gas emissions? What are the natural causes of these gasses? Thanks to the carbon cycle, carbon dioxide eats away at the earth's atmosphere with the intensified help of humans. Young scientists...

High schoolers carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete...

Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

The Gulf of Mexico dead zone, an area of low oxygen that kills marine life, costs the United States $82 million every year. Young scientists research anoxic ocean environments then come up with a hypothesis for the cause of the Gulf of...

Students examine the life cycle of plants. In this plants lesson plan, students identify the various stages of plants and their parts. Students compare the life cycle of a plant with that of an animal. Activities suggested can be...

Part three in the series of seven has pupils discussing the different greenhouses gases, learning about the carbon cycle, and then watching a short video about the carbon cycle. Based on their knowledge, individuals complete a greenhouse...

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 are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...

Students exercise their muscles to explore concept of heart rate and to explain how blood supplies muscles with oxygen.

Forests, through sequestration, capture excess carbon dioxide in our atmosphere and store it, aiding in climate change. The third installment in a four-part series on how climate impacts forests explores carbon sequestration....

Thirty percent of the world's oxygen is produced by rainforests found throughout the world. Seventh grade learners explore the processes of photosynthesis and respiration through 10 days of labs, manipulatives, and discussions. They...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Seventy percent of the air pollution in China is due to car exhaust. Under the umbrella of environmental chemistry, learners extensively explore air pollution. From the makeup of our atmosphere to sources of major air pollutants, classes...

Climate change affects even the largest and intimidating of landforms—even Mount Everest! A resource helps teach learners the connection between global climate change and its effects on Earth. Activities include videos, class discussion,...
