* Earthworms
* Protozoa
* Bacteria
* Microscopic fungi
* Fungi

Question 3

What are the steps to experiment on mould growth at different temperatures?

Answer 3

1. Get 2 identical slices of bread and 2 identical plastic plates
2. Add a little bit of water on the bread, ensure it’s not too wet
3. Leave the bread in the air for about 30 minutes for microorganisms to reach the bread
4. Cover each bread with a plastic zip block bag
5. Place one plate in a warm place and one in a cold place
6. Record the appearance each day.

This experiment helps to observe the effect of temperature on mould growth.

Question 4

What safety measures should be taken during the mould growth experiment?

Answer 4

1. Do not open the zip block bag to prevent mould spores from spreading into the air
2. Wear gloves

These measures help maintain a safe environment while handling potentially harmful mould.

Question 5

what conditions do you need for microorganisms to grow?

Answer 5

it needs to be moist and the perfect temp
