Build an Oxygen Plant

On September 26, 1991, four women and four men entered the scientific experiment, Biosphere 2; the doors were sealed for two years in order to study the interactions of a biosphere. In the activity, scholars explore biospheres by...

Students conduct an experiment to evaluate whether plants need light to survive and grow. They observe and gather data about plant responses to different growth regimes, analyze the data, and make conclusions about basic plant needs.

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. 

Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

For this origin of life worksheet, students write answers to five questions. They describe characteristics of the first life forms and how scientists believe oxygen accumulated in the Earth's atmosphere.

During an inquiry-based activity, scholars decide which variable to test and then design an experiment to determine the needs of producers. After two weeks, they complete a full analysis and research paper.

Where this is not exactly a lesson plan, it is a terrific outline of how to generate biogas from an animal manure sample. If you are up for the challenge, the generator can be built by your class as a concluding project at the end of an...

What is biogas and how is it made? After examining background information about the sources of biogas and biogas generators, class members follow the provided information and build a biogas generator that can be used in the classroom.

Students explore decomposition and soil health by creating their own garden.  In this agriculture lesson, students build a "lasagna garden" with organic matter found in the area and plant perennials native to their region.  Students are...

Students see how certain plants are very important to us. They explain that healthy plants are important to keep people healthy. They study the major parts of a plant (root, stems, leaves, flowers, fruit and seeds) and their basic...
