How to reference this medium
The teacher instructions include information on the following: the main question, relevance to the curriculum, skills, notes on conducting the subexperiments, the research group, further research assignments, the reference to technology and the reference to values.
The experiment comprises three subexperiments:
• Hand washing
• Cooling without electricity
• Acid on the teeth
Diseases are often transmitted by bacteria that have settled on our hands, in our mouths, or in spoiled foods. However, as long as we practice good hygiene, we can protect ourselves from disease and thus preserve our health. But what does a sufficient level of hygiene mean for our hands, food, and mouths?
Notes:
• Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
• All materials mentioned in the instructions will have to be purchased directly from commercial sources.
