activity to study the permanent slide bread mould
Answers
Answer:
I tried my best to do this it took 15 min.
Explanation:
Aim
To study the growth of mold on bread samples every alternate day, for a course of 2 weeks.
Caution
If you are allergic to mold, then avoid performing this experiment or use mask and gloves for safety. Seek permission from your parents and teacher before you start with the experiment. Also, after you are done noting down the results of the experiment, dispose off the bags containing moldy bread safely, without opening them.
Equipment
Here is a list of materials you will need to perform the experiment.
5 slices of bread
5 transparent sealable bags
Gloves
A mask
Sticky labels
A marker
Magnifying glass
5 - 7 cotton swabs
A tablespoon
Lemon juice/water/apple juice/salt/sugar (at least two of these items are required)
Procedure
Growing mold can be a simple experiment, and performed on a slice of bread. However, to make it interesting and more detailed you can work on 5 samples of breads rather than just one. So, gather the above equipment and follow the below steps.
Take the cotton swabs and run them over areas which have dust, like under a table, bed, or basement.
Then rub the dust from cotton swab over the first bread slice.
Repeat steps 2 for the other four bread slices.
Seal three bread slices inside three transparent sealable bags.
Put sticker on the three bags, and write down using a marker on them.
On the first sticker write "Sample #1 - Dark Closet"; on second write "Sample #2 - Refrigerator", and on the third write "Sample #3 - Under Light".
So, keep the first sample in a dark closet, second in a corner of the refrigerator where it doesn't gets disturbed, and the third one in an area of the house which is most of the time brightly lit.
Now, take the remaining two samples. Before you seal them in the bags and mark them with sticker add one of the above mentioned five items to them. For example, on the fourth bread sample you can add some salt, while on the fifth you can add 2 tablespoons of water. Keep these two sample in a place where they don't get disturbed.
Observations
Wear mask and gloves whenever observing the bread mold samples. Make sure you observe the five bread samples every alternate day at a fixed time of the day, say 2 pm. It is important that you observe them every alternate day without fail, and note down your observations in a table. You can note down their physical appearance like color, shape, amount of growth per day, texture, etc. Another column of your table can be observations of the mold under the magnifying glass. If you want, you can take videos or pictures of the mold every alternate day. This will help in concluding your experiment.
