Lemon Bread Research Paper

3. INTRIDUCTION

In this investigation project I was testing to see which of my potatoes will prefers to grow in favorable conditions (dark, moist places) or if they will grow in non-favorable conditions (lemon juice). I wanted to see if the potatoes will grow mould on them while being in the lemon juice and in a dark moist place for a week (7 days). However, my potatoes rather grow in a non-acidic to low acidic, dark, moist, high in protein place because it thrives in those conditions better. Mould is bacteria that has grown on the dead, it is saprophytic which means they live off the dead as a source of food supply. When I was doing my research about the conditions that bacteria thrive in is 4.4˚C - 60˚C.

PROBLEMS BEFORE INVESTIGATION

• Do the containers that the potatoes will be in have to be clean to achieve accurate results?

• How often would I have to observe the potatoes?

• Will the results of the potatoes differ in favorable conditions to non-favorable conditions?

• What would happen if the containers are different sizes will that influence my results in my project?

• What would happen if someone were to have move my potatoes?

6.HYPOTHESIS

The potato exposed to dirt in favorable conditions (warm, moist, dark) will grow more bacteria (fungi growth in mm) than the dirty potatoes in non-favorable conditions (lemon juice) over a period of 7 days (a week).

7.AIM

The aim of this investigation is to see whether potato fungi prefers to grow on a clean non- touched potato or on a dirty potato or on clean potato non-touched but in lemon juice potato or on a dirty potato in lemon juice.

8.VARIABLES

Dependent:

Bacterial growth (mm)

Independent:

Conditions (dirty or clean potatoes with or without lemon

• Put the rubber gloves back on so that you can put your clean potatoes in to their container.

• Use the fork to pick up the potatoes but make sure that the side where you cut is facing upward for the clean then do the same with the other two halves but take off the gloves before putting them into their containers.

• Put each half in to a container.

• Get your measuring cups and the lemon juice pour 6 teaspoon of lemon juice into two of the container (C(clean), D(dirty)).

• Once you have poured the lemon juice into the two containers get the clingwrap and cut four pieces of the clingwrap with your scissors (make sure that it’s big enough to cover the opening of the container).

• Pull it tight over the opening of the container and makes sure that it is sealed tightly so that nothing can come inside.

• Record the results in a table

12.PRECORTIONS

• Make sure that you wash the containers well before you use them and dry them off with a clan towel.

• Make sure that you don’t burn yourself when you are using the stove.

• Boil the potatoes well to get rid if any
