Have students record their observations and measurements and then analyze and interpret the data to draw conclusions about the effectiveness of garlic and mint at killing bacteria.
Introduce the topic by discussing the importance of bacteria and the various ways in which it can affect human health. Explain that the investigation aims to compare the antibacterial properties of garlic and mint.
Have students research the history and uses of garlic and mint in traditional medicine. They can also research any scientific studies that have been done on the antibacterial properties of these plants.
In small groups, have students design and conduct experiments to test the effectiveness of garlic and mint at killing bacteria. Some possible methods for this could include:
Extracting the essential oils from garlic and mint and using them to treat bacterial cultures
Crushing garlic and mint and applying them directly to bacterial cultures
Making a garlic or mint tea and using it to treat bacterial cultures
Have the groups present their findings and results to the class and lead a discussion to review and evaluate the methods used and the conclusion drawn.nd mint at killing bacteria.
