Mouldy Bread

There’s nothing worse than finding a mouldy piece of fruit in the bottom of a bag. Who ever thought that mouldy bread would lead to a the development of modern antibiotics? More cultures that you might know used mould to help prevent infection. Poultices of mouldy bread were used in ancient Egypt, ancient India, and ancient Greece, and penicillin, an important antibiotic, is derived from mould spores.

Mould spores are everywhere just waiting for the right environment to grow and multiply in. But what is the best environment for them? Is it cold or warm? Sunny or dark?

What You Need:

  • 1 piece of bread
  • 1 resealable plastic bags
  • Permanent marker
  • Water

What You Do:

  1. Put one slice of bread into the sealable plastic bag.
  2. Take your bag and place it in the environment where you believe mould will best grow.  Make sure your bag is sealed tightly. Label the bag with a marker.
  3. Develop a hypothesis as to what will happen to the slice of bread. Think about where mold grows naturally. What conditions are conducive to mold growth in nature?
  4. Check your bag daily to record any changes you see, and compare the results with your hypothesis.

Did You Know?

  • Different types of mould grow in the dark versus the light, and cold versus warm temperatures.
  • All mould is dangerous to eat. If you ever have a slice of mouldy bread it is recommended that the whole loaf be thrown out. Mould spores are microscopic and are already all over the entire loaf even if colonies haven’t developed yet.

    My hypothesis is that the bread should be damp but not in a pool of water. It also needs to be in a light/dark place so it gets some warm light through the bread but also some dark growth so it is moist. The warmth from the heater will keep it growing but it can’t be too close otherwise it will dry out.

    my hypothesis is that the mould wont grow because its a living thing and the air is trapped inside it.

    My Hypothesis is that mould will grow on bread in a moist, environment with a natural light so that the bread will get enough light but also some dark. The bread will grow some mould from the warmth of the heater but it is far enough away so that it won’t dry out.

    My hypnotics is that the bread will get mould if it is in a plastic bag tired up so no air comes out
    and maybe a bit of water because water makes mould
