2) Investigate which products can change the pH of bacteria.
3) Cultivate the same bacteria in 8 different petri dishes.
4) Add the lowest pH product (we have to put a filter which we would need to soak with the product and put it in the petri dish) to one of the petri dishes.
5) Leave the bacterias in the petri dish for an hour and after that, observe them under the microscope.
6) To observe them, we have to dying the bacteria with methylin blue.

7) Repeat the process number 4 with all the different products, but every different week and adding a new product to each petri dish.
8) Each week use a different petri dish and add a different product.
9) Everytime we use a product and observe it we have to take note of what we see (how the bacteria have reacted to the different products)
10) Make a table with all the information that we get from the bacteria and how they have reacted and finally, write down our conclusions.
