The Pickle "Dill"emma

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

There are five methods of seed dispersal. They include gravity, mechanical, animal, water, and air. Scholars study seed dispersal in lesson plan five of the series of six. Through discussions, hands-on analysis of different seed types,...

Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

Grow plants from seeds! Explore the methods of propagating plants and the best ways to germinate seeds for all types of plants. Details about the treatment of seedlings and ways to increase efficiency in your production of numbers are...

Ginkgo trees existed for more than 350 million years, and, at this time, only one species still remains. While plant diversity generally increases over geologic time, some interesting exceptions occur. Young scientists learn about plant...

Young botanists dig into a lesson that has them planting lima bean seeds and observing their growth. They compare their experience to that of the speaker in Robert Frost's poem, "Putting in the Seed."

Use indirect measurements to monitor metabolic activity in plant cells. Scholars understand that cells with a higher metabolic rate have a higher concentration of catalase enzyme. They use this information to compare metabolic rates of...

Clean, renewable energy is there for the taking ... how do we save it until we need it? A short video, part of an energy unit from NOVA, discusses the challenges of creating and storing electrical energy efficiently. The narrator...

What happened to the plant in math class? It grew square roots. Here, a set of 11 worksheets provide a review of plant reproduction. It includes the structure of a flower and each part's function, pollination, fertilization, seed...
