Plant Power Slides Field Expedition 01
Plant Power
Unlocking the secrets of photosynthesis and the green machines of our planet.
The Big Question
How do plants make their own food out of thin air, sunlight, and water?
The Recipe for Energy
Sunlight
The fuel that powers the entire process.
Water
Absorbed by the roots from the soil.
CO₂
Carbon dioxide taken in through the leaves.
The Green Machine
Inside every leaf are tiny "solar panels" called chloroplasts.
Fun Fact
Chlorophyll is the pigment that makes plants look green. It's also the magnet for sunlight!

The Transformation Formula
Inputs
Sunlight

Photosynthesis
Process
Outputs
Glucose
(Sugar)
Oxygen
Why does it matter?
Breath of Life
Plants release Oxygen as a byproduct. Almost all living things need this to breathe!
The Base of Food
The Glucose plants make is the primary source of energy for the whole food chain.
Field Expedition Recap
Photosynthesis converts light into chemical energy.
Plants need sunlight, water, and carbon dioxide.
The results are glucose (sugar) and oxygen.

The Big Question
How do plants make their own food?
The Ingredient List
Circle the three things a plant needs to start the process of photosynthesis:
Sunlight
Pizza
Water
Carbon Dioxide
Batteries
Moonlight
Inside the Leaf Factory
Plants have tiny "solar panels" inside their leaves called Chloroplasts. These contain a green pigment called Chlorophyll.
What color does Chlorophyll make a plant?
CHLOROPLAST
The Magic Formula
Fill in the blanks to complete the photosynthesis equation:
Sunlight
Sugar (Glucose)
Why it matters
1. Plants give us Oxygen. Why is that important for you?
2. Plants make Glucose (Sugar). Who or what uses this sugar for energy?

Leaf Lab Activity Leaf Detective Lab
Experiment 01: The Breathing Leaf
Mission
To observe evidence of plants releasing oxygen through a process called photosynthesis.
Materials Needed
Fresh green leaf
Clear glass bowl/cup
Lukewarm water
A sunny windowsill
A small rock
Magnifying glass
Lab Procedure
1
Fill your clear bowl or cup with lukewarm water.
2
Find a fresh green leaf (carefully pick one from a tree or plant).
3
Place the leaf in the water and use the small rock to hold it underwater.
4
Place the bowl in a sunny spot and wait for 1-2 hours.
5
Observation Time! Use your magnifying glass to look at the leaf surface.
Lab Observations
1. Draw what you see on the leaf surface:
2. Describe the bubbles:
The Conclusion:
What do those tiny bubbles prove is happening inside the leaf?
Scientist Tip: The bubbles you see are tiny pockets of Oxygen ! The leaf is still performing photosynthesis using the stored CO₂ and the sunlight from your window, and it's releasing oxygen right before your eyes.

The Big Picture
Draw a quick diagram showing the inputs (what goes in) and outputs (what comes out) of a leaf.

PLANT POWER: INTRO TO PHOTOSYNTHESIS
Grade Level
4th - 6th Grade
Duration
60 - 90 Minutes
Subject
Life Science
Learning Objectives
Identify the three essential inputs for photosynthesis: sunlight, water, and CO₂.
Explain the role of chloroplasts and chlorophyll in trapping light energy.
Describe the outputs of photosynthesis (glucose and oxygen) and their importance.
Facilitation Sequence
01
Introduction & Slides (20 min)
Begin with the Plant Power Slides . Hand out the Field Notes Worksheet beforehand so students can follow along. Encourage students to think about how they get energy (food) vs. how a tree gets energy.
02
Leaf Lab Investigation (30-40 min)
Transition to the Leaf Lab Activity . If possible, set up the bowls at the start of class so the 1-hour wait time happens during the lesson. Have students predict what the bubbles will be before explaining they are oxygen.
03
Discussion & Wrap-up (15 min)
Review the Magic Formula. Discuss the importance of oxygen for humans and glucose for the food chain. Hand out the Oxygen Exit Ticket for the final 5-10 minutes.
Common Misconceptions
Misconception
"Plants get their food from the soil."
Reality
Soil provides minerals and water, but the "food" (glucose) is manufactured in the leaves using light and air.
Misconception
"Plants only breathe in CO₂."
Reality
While they take in CO₂ for photosynthesis, plants also perform cellular respiration and need oxygen themselves to stay alive!
Master Answer Key
Field Notes Worksheet
Ingredients: Sunlight, Water, Carbon Dioxide.
