How Does Our Mould Grow?

Have you ever found that week-old sandwich at the bottom of your bag?

Banana feeling quite squishy?

This could be that they have adapted to their new habitat – and not for the better.

This term Year 6 have been exploring microorganisms in Biological Science. One form of a microorganism we have been experimenting with is mould.

Mould is a fungi that needs nutrients and water to grow. Mould can be found indoors and outdoors all over the world. Most are non-toxic, but they certainly aren’t good to eat!

Mould can grow on surfaces like rocks and walls, but in homes it commonly grows on aging food. Many foods, especially bread, contain mould inhibitors and preservatives to prevent mould from growing quickly.

We decided to grow mould on some bread slices. We had a control slice and then create five different variables to see if we add, change, or move the slices would mould grow faster.

As you can see, we did a pretty good job in finding conditions that make mould grow. We know not to open our bags to smell the mould, as it could cause problems.

Conclusion, always check your lunch box or bag for mouldy bread.

As God has provided for us, we know he has also provided for the other living things in this world. Some animals learn to adapt to new habitats to survive. God has provided them with claws, fur, beaks, fins, and eyes to assist them all to survive in this world. We decided to grow some sunflowers, but once again we used different variables to see if a sunflower will grow. This might take longer than the mould but we will be patient and see what happens.

As we say in Year 6 – Watch this Space!
