My results show that the black pepper section has the largest amount of bacteria, followed by the control section. The cinnamon section has the least amount of bacteria.
In conclusion, cinnamon repels bacteria, black pepper encourages bacteria and my mouth has a lot of bacteria.
This proves my hypothesis with product 1-black pepper is incorrect. Black pepper can't kill bacteria by heating it up.
However, my hypothesis with product 2-cinnamon is correct. Cinnamon is effective in killing or inhibiting microorganisms.
My experiment also shows that salt and pepper will melt the gelatine solution. Next time if I conduct a similar experiment, I will use agar instead of the gelatine solution.
