🔬 What is this experiment?
Question: Do yeast cells make gas?
You will mix yeast with sugar water. Then you will watch what happens.
If yeast are alive, they will eat the sugar. They will make gas come out.
The gas will fill up a balloon!
🧫 What is yeast?
- Yeast = tiny living cells (too small to see)
- Yeast is alive! It needs food and makes gas.
- We use yeast to make bread fluffy
- Yeast eats sugar → makes CO₂ gas + energy
🧪 What you need:
- 2 small bottles (like water bottles)
- 2 balloons
- Warm water (not too hot!)
- Sugar (1 spoon)
- Yeast (1 spoon)
- Marker to label bottles
📝 Steps - Do this:
Step 1
Label your bottles:
Bottle #1: Write "SUGAR WATER"
Bottle #2: Write "PLAIN WATER"
Step 2
Make Bottle #1 (Sugar Water):
Put warm water in bottle (fill halfway).
Add 1 spoon of sugar. Shake it.
Add 1 spoon of yeast. Shake it gently.
Step 3
Make Bottle #2 (Plain Water):
Put warm water in bottle (fill halfway).
NO sugar! Just add 1 spoon of yeast.
Shake it gently.
Step 4
Put balloons on top:
Stretch balloon over Bottle #1.
Stretch balloon over Bottle #2.
Make sure balloons fit tight!
Step 5
Wait and watch:
Set bottles in a warm place.
Watch for 60 minutes.
Write down what you see every 10 minutes.
📊 Write what you see:
Look at your balloons. Are they getting bigger? Write what happens!
🤔 Think about it:
- Which balloon got bigger? Why?
- Why did we use plain water with no sugar?
- What gas filled up the balloon?
- Where did the gas come from?
- Is yeast alive? How do you know?
💡 What you learned:
Sugar water balloon got BIG! Why?
- Yeast cells ate the sugar
- Yeast made CO₂ gas
- Gas filled the balloon
- This proves yeast are ALIVE!
Plain water balloon stayed FLAT. Why?
- No sugar = no food for yeast
- No food = no gas made
- This is called a "control" (helps us compare!)
🍞 Real Life Connection:
This is how we make bread!
Bakers put yeast in bread dough.
Yeast eats sugar in the dough.
Yeast makes CO₂ bubbles.
Bubbles make bread fluffy and soft!
