Photosynthesis Lesson Plan Grade 9 Applied Science
By: Allison Cunningham
Specific Expectations from Ontario Curriculum Document
B3.3 describe the complementary processes of cellular respiration and photosynthesis with respect to the flow of energy and the cycling of matter within ecosystems (e.g., carbon dioxide is a by-product of cellular respiration and is used for photosynthesis, which produces oxygen needed for cellular respiration), and explain how human activities can disrupt the balance achieved by these processes (e.g., automobile use increases the amount of carbon dioxide in the atmosphere; planting trees reduces the amount of carbon dioxide in the atmosphere)

DIRECT INSTRUCTION LESSON PLAN
Name: Allison Cunningham_______ Grade: ___9____ Date: October 3, 2012 Strand: Applied _____________ Topic: Photosynthesis ______________________
Learning Goals (General/Specific)(Knowledge, skills etc) Learners will be able to:
1. Have a very general idea of the complementary processes of photosynthesis and cellular respiration (from video)
2. Describe what photosynthesis means.
3. Describe what plants need for photosynthesis and where plants get energy, water and CO2 from.
4. Describe that photosynthesis produces oxygen and sugars.
5. Identify organelles called chloroplast and understand that photosynthesis takes place in chloroplasts. Understand why animals don't have chloroplasts.
6. Understand what is meant by chlorophyll.
7. Explain how human activities can disrupt the balance achieved by

Introduction\Motivation
PROCEDURE
Time
Welcome class. Smile, make eye contact, and welcome students by name.
15-20 min
Display some wacky weird plants at the front of the class so everyone can see them - because plants are cool!
Tell the class we will be talking about plants and some of their interesting features - like how plants can make their own food and that they produce the oxygen us humans need to live.
Have written on board a few critical questions for students to consider: - What is photosynthesis? - What do plants need for photosynthesis? - What do plants produce?
Show interactive video, from OERB, on photosynthesis and cellular respiration (Resource ID : ELO1342620) ? this provides good
introduction to the two processes and how they relate to each other. (Technology/Media based strategy)
Have students play with video ? ask for 3 volunteers to come up to the computer and add cars and trees etc.
Randomly assign students to groups of 5 (counting out 1-5 around classroom).
Ask students to discuss, in their groups, what they saw happen when more cars were added to the system and when more trees were added to the system.
Ask them to focus on the plants. What are the plants taking in and emitting? What are the humans taking in and emitting?
Ask for groups to volunteer to answer these questions.
Use this to jump into more details on photosynthesis. Explain to the class that the focus of today's lesson will be photosynthesis.
Sequence of Steps for Learning Min(s) Strategies to Match Sequence of Learning
1. Present Powerpoint
20
presentation. Define
photosynthesis. Highlight what
plants need for photosynthesis ?
SUNLIGHT, WATER, CO2.
Highlight what plants produce ?
OXYGEN, SUGAR.
In presentation include a description of chloroplasts. Describe that they are organelles only found in plants and they are the site of photosynthesis.
1. Direct Instruction Strategies - read and follow along with Powerpoint presentation presented by teacher (tell students they must have a way to record this information ? taking notes is a good idea. teacher will also post the slides on the course website)
2. Run through macro model of 25 photosynthesis ? see attached description. Use previously selected groups of 5 students.
2. Activity based StrategiesSimulation
3. After simulation exercise is
5
complete ask students, in their
groups of 5, to talk about why
photosynthesis is important to
3. Thinking Skills Strategies- concept clarification
them and to other animals. Ask each group to share one idea.
Recap\Review
Homework ? pass out sheet with various questions/definitions for students to complete for next class.
