Grow A Colony Of Mold Biology Science Experiment
In this fun and easy biology science experiment, we’re going to grow a colony of mold to explore and investigate.
- Aluminum foil
- Magnifying glass
- Put the lemon in the jar and add a small amount of water.
- Cover the lid tightly with the aluminum foil and place the container in a warm dark space.
- Store the container for a week or more.
- Remove the lemon and examine the mold with the magnifying glass.
- Once you have finished examining the mold, return the foil cover and dispose of the lemon. Wash your hands thoroughly once finished.
How it Works:
Mold grows on dead organic matter but only becomes visible to the naked eye when it forms a colony called mycelium. Mold digests (or eats) the organic material it is growing on. Mold is very important because it helps break down decaying plants and animals.
Make This A Science Project:
Try different fruits. Try placing the jar in a refrigerator to see if the cold slows or increases the mold development. Try adding salt or vinegar to the experiment and observe if this slows that rate of mold growth.
