The Process of Photosynthesis

Lab Brief #5

🎯 Your mission

Predict it first. Then prove yourself right (or wrong).

⚡ The twist

Living things break the rules of non-living things — find the rule they break.

What you'll learn

Photosynthesis converts light energy into chemical energy stored in glucose. Plants use carbon dioxide from the air and water from the soil, releasing oxygen as a byproduct.

Key words

photosynthesis
How plants use sunlight, water, and air to make their own food.

Make a hypothesis first

Predict: what will happen to the plant if you change the water?

Say your guess out loud — then find out if you were right.

Get ready

🧰 What you need

water

⚠️ Safety first

Never look directly at the Sun or into a laser, even briefly.
Mop up spills straight away so nobody slips, and keep liquids away from sockets.

Step 1 of 4 · Read

Look at the vocabulary words and write a definition for each in your own words.

Step 2 of 4 · Do

Design a controlled experiment: grow plants under different light conditions (full sun, partial shade, no light). Water equally and measure growth daily for one week.

Step 3 of 4 · Observe

Look for patterns in your observations.

Step 4 of 4 · Record

Make a graph or chart showing your results.

Question 1 of 3

What do plants need to make food through photosynthesis?

How sure are you?😐 maybe

Question 2 of 3

What gas do plants release during photosynthesis?

How sure are you?😐 maybe

Question 3 of 3

What is the function of chloroplasts in plant cells?

How sure are you?😐 maybe

Mind = blown

🌳 Trees can talk to each other through underground fungus networks.

Nice work!

You got 0 of 3 right.

🏆 Stretch challenge (try it this week): Watch a plant or pet for 5 minutes today and write down what you noticed.

👨‍👩‍👧 For the dinner table: “Tell me something you noticed about your own body today.”
