Synopsis: This unit will look at light and how it is a requirement of plants to survive. Different wavelengths of light affect photosynthesis differently. Students will work to design an experiment to observe how different wavelengths of light affect the plant’s growth. This will lead into a discussion on food chains/webs, where students will discover that the sun and plants are the beginning of every chain/web. This unit will require students to take measurements and record data at least once a week for at least three weeks.
