What's in a Willow?

Plants need food to survive, just like any other living organism. Young biologists analyze an experiment performed in 1610 by Jan van Helmont to determine if plant nutrition is obtained through the soil. First, lab groups work together...

Beginning botanists can sketch the parts of a plant in individual boxes, or better yet, they can tape or glue actual plant parts in them. Beside each box are a few sentences with selected words left out. From the word bank at the bottom...

Plants provide a variety of delicious foods essential for human survival. In the fourth lesson of this series on food science, young scientists investigate common fruits, vegetables, and grains in order to determine which plant part is...

Young scholars describe typical marine food webs, and explain why food is generally scarce in the deep-ocean environment. They discuss reasons that seamounts may support a higher density of biological organisms than would appear to be...

Although the points given on these slides are valid, the visual accessibility is poor. Consequently, many viewers would be distracted or entirely unable to view the presentation.  The content is a review of microorganisms and their...

Beginning botanists view slides of plant vascular tissue. They watch Magic School Bus Gets Planted, which you can find online, and then write a summary of what they have learned about plants. This activity could be used with upper...

Students explore basic nutrition concepts to help them select healthy diet, evaluate food intake, discuss major food labeling issues, design labels for food products, examine history of food packaging development and how packaging...

Learners observe seeds growth and examine the different parts of the seedling. In this biology lesson, students compare the growth of seeds planted in soil and in hydroponics. They record their observations in their science journal and...

In this energy flow worksheet, students will complete 10 short answer questions based on a food web diagram. Then students will review different cycles in nature including the water cycle, carbon cycle, and energy cycle. This worksheet...
