Here's how.

Plants provide us with so much — oxygen to breath, food to eat, materials to make clothing and paper, and beautiful flowers and leaves to admire! How can plants be so diverse and survive in so many kinds of climates? How do they know how to grow towards the sun? Why do some plants not have seeds? Explore the amazing and beautiful world of plants.

Flowers Seeking Pollinators

Lesson Plan Grade: 3rd-7th

In this activity, students learn about plant reproduction and use real data to construct explanations about which flowers are the most attractive to different pollinators. Read more

NGSS Performance Expectations:

3-LS1-1. Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.
4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
MS-LS1-4. Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants, respectively.

Plant Cycles: Photosynthesis & Transpiration

Lesson Plan Grade: 3rd-5th

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 predictions about the outcomes and record ongoing observations of the condition of the stems, leaves and roots. Then, several healthy plants are placed in glass jars with lids overnight. Condensation forms, illustrating the process of transpiration, or… Read more

NGSS Performance Expectations:

5-LS1-1. Support an argument that plants get the materials they need for growth chiefly from air and water.

Stomata Printing: Microscope Investigation

Lesson Plan Grade: 3rd-12th

Plants have many crucial roles on our planet, and among these is the gas exchange that happens within their leaves. As plants take in carbon dioxide from our atmosphere, they release oxygen and retain the carbon. In this lesson, students will investigate leaves up close to look for the structures responsible for gas exchange. Read more
