Germs are all around us: in our bodies, on the food we eat, and even on the crayon we just used to draw a picture. Some are helpful and some are dangerous. This colourful, engaging, and informative resource takes readers of all levels on a journey through time, exploring the history of germs and diseases, and providing information on scientific influences and developments throughout human history. Suitable for both a younger and an older audience, the book complements a Grade 2–6 Physical and Health Education class particularly well, lending itself to discussions about improving personal well-being and preventing illnesses. Students may be encouraged to create posters on hygiene, study how medicine has changed over time, or compare and contrast helpful and harmful germs. Log in to read the full review.
