8.3: Ecology 3 Dimensions & Progressions

Unit 3

● I can explain how matter is transformed from carbon dioxide and water into glucose and oxygen molecules in the process of photosynthesis. ● I can explain how energy

is stored in molecules during photosynthesis.

Activity: Light Intensity

Objective

Overview

Materials

● I can test the variable of light intensity on the rate of photosynthesis.

● Experiment: Have

● 2 potted plants, same type and age ● Lighted area 24 hours if possible ● Dark area ● Student Worksheet

students observe two healthy potted plants and have them predict what would happen to one of the plants if it did not receive any light for a week. Conduct an experiment to test their class predictions. Keep the temperature and the amount of water constant.

Activity: Light Distance

Objective

Overview

Materials

● I can plan and conduct an investigation to test a variable’s effect on photosynthesis.

● Students with guidance from the teacher will manipulate the variable of light distance to determine the effect on the rateof photosynthesis.

● Light Effect on Elodea Photosynthesis Rate Lab ● Lesson Plan

Activity: Photosynthesis Review

Objective
