Your task today is to create a Lab Proposal & Submit it
First, come up with a hypothesis statement that you are going to test. Start by asking questions such as: What do you want to test? Light versus dark? Wet versus dry? What do you think will mold faster or won’t mold at all?
A hypothesis is an educated guess about how things work. It is an attempt to answer your question with an explanation that can be tested. A good hypothesis allows you to then make a prediction:
“If __________(I do this)__________, then __________(this) __________will happen.”
NB. Once you have a good hypothesis, put it in the section below.

What should be in your Lab Proposal?
Typed on one page:
Title- Your name, the date and an appropriate title
Purpose (Example: To investigate the conditions needed for mold growth….).
Hypothesis Section
1) Variables Identified: Identify your variables and state which one is your independent, dependent and controlled variables (list at least three).
2) Hypothesis Statement: Be sure to include the independent and dependent variables in your statement (this helps to make the statement specific). Also, remember that your hypothesis needs to be testable, so be sure to have your procedure thought out before you finalize this statement.
Materials- List materials and quantities like you would in a recipe “ingredients” section prior to the recipe steps.
Procedure -Detailed, but concise, numbered step-by-step instructions of how the lab will be set up. Write it as though you were giving directions to someone else (third person; no “I” statements). Remember to include:
1. a comment about what your controlled variables are.
2. a safety comment on how you are going to limit mold spore exposure during the experiment and when you are disposing of materials at the end of your experiment.
3. a step stating: Allow bread samples to collect spores on counter for 20 minutes.
4. a step stating: Take a picture of the last day of the experiment that includes the bread slices in their bags and a piece of paper with your name and date on it.
5. a step stating how you will record your results and what results you are looking for: i.e. Make sure your procedure outlines both quantitative and qualitative results you were observe. Ways you might measure mold quantitatively: with a ruler to measure your mold growth spots and calculate areas, count the number of different types and amounts of spots or a good way to estimate the amount of mold is to estimate percent coverage on the bread each day. For percent coverage you might consider using a grid to help you accurately estimate. This way you can get a sense of the change and amounts over the 7-10 day period.
Questions to consider: can you think of any questions that might arise as you are completing this experiment? Include them here. For example, if you are testing moist/dry, how many drops of water will you put on your bread? If you are testing temperature, how will you keep track of the daily temperature? What observations will you make on a daily basis? Write as many as you are thinking about! NB. Later in your formal lab report you wouldn’t have a questions section. However, you will either take your questions and use them to help set up your procedure or you might reflect on them in your discussion section.
