Molding Pears BY :Tessa Barrow-Precious

How to get started

Instructions 1)Cut two pears into eight pieces each. 2)Put two pieces onto each of the five plates. 3)Keep one plate clean without anything done to it. 4)Heat honey for ten seconds and pour onto the two pieces on one plate. 5)Drizzle olive oil on another plate. 6)Follow the last step except pour milk on a plate and then pour lemon juice on the other. 7)Slip each plate carefully into their own Ziploc bag. 8)Seal firmly. 9)Set in safe place where experiment cannot be bumped. 10) Finally eat the leftover 6 slices of pear.

December 10 th 1.The microorganisms growing on rim of all pear slices had a green color to them. 2.White colonies covered and still cover the pear with milk. 3.Blue mycelium on lemon, honey and olive oil.

December 22 nd 1. By now colonies cover everything in blankets. 2. Underneath, pear is turning a chard looking brown. 3. The milk on the pear looked like whipping cream.

Milk

Conclusion To conclude, the experiment was a success and was not a mess. My prediction was correct that the mold did have the most growth on milk because of the dairy. That being said the mold was the slowest to grow and is different. Next time I would take pictures more frequently and monitor the growth of the colonies more closely.
