2. BIOLOGY– Plant Growth Experiment
Warm-Up:
What do plants need to survive?
Today:
Introduction to Plant Growth Experiment
Research

3. What do plants need to survive?
Sunlight – make food through photosynthesis
Gas Exchange (CO2 and O2)
Water and Minerals
PHOTOSYNTHESIS
6 CO H2O → C6H12O6 + 6 O2
Carbon dioxide + Water + Light energy → Glucose + Oxygen

4. What factors influence plant growth?
Brainstorm

5. Plant Growth Experiment
Purpose:
Describe the characteristics and growth of a specific species of plant.
Design an experiment to test how an experimental variable will affect plant growth.
Directions:
Each Group will have 4 plants. Half of these are controls and the others will be the experimental.
You will be responsible for taking care of your own plants.

6. Plant Growth Experiment
Conduct background research about plant growth.
Develop a question about how a particular treatment will affect plant growth.
Develop a hypothesis based on research.
List the materials you will use for this experiment.
Design an experiment to answer that question.

8. Today Conduct background research about plant growth.
Use the internet and seed packet to research general information about your plant
Keep track of websites visited for works cited
When finished with the general information section of the research organizer, write the first paragraph on background research.
