Students discuss the parts of the plant and perform an experiment in which they observe a plant's water transportation system. They become familiar with several local plants used for utilitarian purposes.

Students examine the roots of various plants. They study and discuss the cross section of a root. They compare different plants with their root systems and complete a worksheet, giving the function/importance of each root part.

Students match roots and seeds to the plants they belong to . They comprehend how weeds spread and become established. Students match two roots with their plants. They match two seeds with their plants. Studens describe why weeds...

High schoolers investigate the models for the origin of modern humans and the conditions that facilitate speciation and evolution. The classification and nomenclature of hominid species is also examined.

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

In China, hibiscus is known as the shoe flower because it is used to polish shoes, while in Hawaii, it is honored as the state flower. Young scientists learn about the structure and function of flowers. They dissect hibiscus...
