Students Explain how an increased level of activity translates to cells needing more oxygen and how the lungs supply this oxygen by entering the blood stream. They also can explain that the heart is responsible for moving both oxygenated...

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...

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....

She had a terribly busy day converting oxygen into carbon dioxide; now she just needs a moment to breathe. In the activity, scholars review the function of the respiratory system and discuss bioengineering's role in medicine/health and...

One hundred metric tons of CO2 can accumulate in one acre of forest over time—that's a lot of carbon! In the activity, groups of middle school learners determine what makes forests important. They then solidify the concept by using a...

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. 

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...

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

Trees are the star of a three-step unit celebrating Arbor Day. Step one takes an in-depth look into the structure of a tree, the process of photosynthesis, and the benefits of the leafy giants. Step two challenges scholars to create a...

Fifth graders work in small groups to brainstorm responses to a problem related to some disaster that wipes out half or all plant life on earth. Groups complete a graphic organizer to compare and contrast their ideas. Students select...

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...

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...

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...

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...

What is the relationship among the heart, circulation, and exercise? Your class members will explore first-hand how different physical exercises affect an individual's heart rate. They will begin by learning how to measure their own...

How do plants and animals get their food? Learn about where energy comes from, how animals store energy, and aerobic respiration, in a lesson plan that allows scholars to diagram energy flows. 

More asthma attacks happen at higher altitudes, but why? Scholars complete worksheets, learning about homeostasis and feedback related to breathing. Then, they work in small groups to experiment with breathing in limited amounts of...

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 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 their...

Beginning with a general discussion about natural gas, methane, and hydrocarbons, a few videos and diagrams are projected to support the lecture. Individuals participate in a brief activity by drinking juice through a straw, and then...

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,...

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...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

Imagine an ecosystem without any light or oxygen, where living things convert carbon dioxide into food. This ecosystem is thriving and might just be the largest ecosystem on our planet, yet we know very little about it. The lesson...
