Photosynthesis: How Plants Make Food
Grade Level
7th grade
Lesson Objectives
By the end of this lesson, students will be able to:
- Explain how plants convert sunlight into usable energy
- Identify the key inputs and outputs of photosynthesis
- Describe the role of chloroplasts and chlorophyll in photosynthesis
Materials
Colored paper, scissors, tape
Flashlights
Clear plastic cups, straws
Baking soda, water
Worksheets, exit tickets
Lesson Plan
Opener (5-10 min)
Show a short video clip of a time-lapse of plants growing towards the sun
Ask students to discuss with a partner: What do you think is happening? Why do plants need sunlight?
Call on a few pairs to share ideas and write key words on the board (e.g. sunlight, energy, growth)
Introduction (10-15 min)
Explain that today we'll be learning about photosynthesis - the amazing process plants use to make their own food using sunlight
Draw a simple diagram on the board showing the inputs (CO2, H2O, sunlight) and outputs (glucose, O2) of photosynthesis
Emphasize that plants are the only living things that can make their own food - all other life depends on them!
Check for understanding: Have students fill in the blanks on the diagram in their notes
Activity 1: Building a Chloroplast (20 min)
Divide class into groups of 3-4 and give each group supplies to build a model chloroplast:
Green paper for chlorophyll
Yellow/orange paper for thylakoid membranes
Clear cup for stroma
Straw pieces for enzymes
As they build, circulate to ask probing questions:
What does the chlorophyll do? (absorbs sunlight)
Where does the CO2 enter the chloroplast? (stroma)
What's produced in the thylakoid? (ATP for energy)
Have groups show and explain their models to each other
Activity 2: Photosynthesis in Action (20 min)
Demo how to set up a simple experiment:
Pour baking soda solution into 2 clear cups to provide CO2
Add a few sprigs of an aquatic plant to each
Place one in bright light and one in a dark closet
Have students set up their own experiments and make predictions
While waiting, explain the equation for photosynthesis and practice balancing it
Check plants at end of class and discuss results tomorrow
Conclusion (5-10 min)
Review key points: photosynthesis uses sunlight to convert CO2 and H2O into glucose and O2
Chlorophyll in chloroplasts absorbs the light energy to power this process
Plants are amazing solar-powered sugar factories!
Preview that tomorrow we'll learn more about how plants use the glucose they make
