Title: Plants, Pigments and Colors
Description: In this hands-on, inquiry based lesson students will see the role of pigments in the in the process of photosynthesis. Students will use the process of chromatography to separate plant pigments. Students will then see the function of these pigments in helping plants maintain life.

Title: Photosynthesis, Trees, and the Greenhouse Effect
Description: In this lesson, from Xpeditions, students study photosynthesis and then then transfer their understanding of this topic to a consideration of how trees can help reduce the negative impacts of the greenhouse effect. They read a Web page describing the greenhouse effect, carbon dioxide's role as a greenhouse gas, and the role of humans in exacerbating this effect. Students also browse the Web site of an organization that sponsors tree planting programs and consider how these programs might help reduce or slow down the increase of the greenhouse effect. They conclude by writing paragraphs telling younger kids about the benefits of trees and plants.

Title: Plant Parents
Description: This Science NetLinks lesson, the first in a two-part series on reproduction in plants, covers how most plants normally reproduce--sexually. In this lesson, students learn the parts of the flower and the process of sexual reproduction in plants.

Photosynthesis: Light Reactions and Photophosphorylation
KHAN Academy light reactions within a thylakoid of a plant cell. The video includes the excited electron releasing energy throughout the membrane to generate ATP and NADPH.
The parts of leaf and the process photosynthesis of are labeled and scored to assess mastery, in this interactive assessment.
Chloroplasts and Pigments
This page, part of the University of California at Berkeley's Photosynthesis web site, features information about plant cells and the photosynthesis process. This resource is referenced in the Science NetLinks lesson titled "Urban Ecosystems 4: Metabolism of Urban Ecosystems."
Educational Resources on Photosynthesis for Teachers and Students
This web page, from Arizona State University, features an extensive list of links to resources that discuss photosynthesis at varying degrees of complexity.
