This comprehensive lesson provides information on the functions of stems, control of stem growth, structure of stems, axillary buds and branching, and modified stems.

Do you like to climb trees? The branches of trees are what make them so fun to climb. Each branch starts out as a tiny shoot that grows out from a stem. How is the growth of shoots along a stem regulated?

Peruse this site and discover some interesting facts about stems as well as learn what its' function is.

What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make...

A challenge that asks students to build a machine that distributes seeds precisely. This site includes a lesson plan, tips, and a place to document their engineering design process.

This activity teaches kids about variables by growing three different plants from seed and explains that variables are something that can be changed in an experiment.

Lesson plan using an apple, tea bag, onion, and celery to teach plant parts and their function.

Inspire students to make a root system to help a plant stay put with simple materials like pipe cleaners, string, and marbles. This STEM challenge allows students to not only solve a problem but get tips and document their process all on...

Read about the basic structure of plants in this short, informational reference piece.

Plants need nitrogen to build proteins and nucleic acids to grow healthy stems and leaves. Though the Earth's atmosphere is made up of 79% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. In this...

You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of...

Students develop an understanding of the effects of invisible air pollutants with a rubber band and hanger air test and a bean plant experiment. They also learn about methods of reducing invisible air pollutants.

The goal is for the students to understand the environmental design considerations required when generating electricity. The electric power that we use every day at home and work is generated by a variety of power plants. Power plants...

Learn how plants absorb water through either root systems or vessels in their stems with this site. Also understand how important water is to the make up of the plant!

By tracing the movement of radiation released during an accident at the Chernobyl nuclear power plant, students see how air pollution, like particulate matter, can become a global issue.

Students will learn about the importance of water and the role it plays in our lives. Students will be exposed to what must occur each day so that they can have clean water.
