Question

Can someone help me on setting up my experiment? This is what I got so far..

Hypothesis: Water will make a better difference for making mold on bread because molds are mostly water.

Materials:
~ 6 pieces of bread
~ Milk
~ Water
~ Investigation notebook / papers
~ 6 zip lock bags
~ 2 empty spray bottles

Procedure:
1. Gather materials
2. Put milk in a spray bottle same goes for the water.
3. Spray the milk twice on 3 pieces of bread and same goes for the water.
4. Put into separate zip lock bags.
5. Do step 3 once every day.
6. Record data / measurements every day.

7. When you know you recorded enough data then record your final data (conclusions, graphs, measurements, etc)

Answer 2

um....this is the math section

Answer 3

ik

Answer 4

how will you know that it was the difference in water and milk, what if one or the other just does nothing..

you should have a third one with all the same conditions as the other 2, but do not do any milk or water

Answer 5

what happens when you do nothing, a control test

Answer 6

i was going to do 3 at first but then the hypothesis i thought you could only do 2

Answer 7

you have the hypothesis ok, water will help mold grow on bread faster than milk

the control bread, is part of the testing to prove that

Answer 8

so bread is control?

Answer 9

for example, how will you show that the water and or milk actually didnt slow down the production

Answer 10

you need a test running in which you do not influence it , and same conditions as all the others

Answer 11

this investigation is suppose to make me know if my hypothesis is correct, so this so the experiment it's self is basically the test run

Answer 12

you are testing if..

water increases the rate of mold growth on bread more than milk increases the rate of mold growth.

right

Answer 13

having part of the experiment run a trial of bread without either the water, or the milk variables, you have a baseline value for the rate of mold growth.

then you can say how the milk and the water really changed the mold production.
you may get values for both milk and water that are worse or better than the control trial.
but you wont be able to tell that one helped growth and one hindered it
