Discover the microbial world all-around you with this great little kit. Prepare a petri dish with the included nutrient agar then get swabbing and testing. Are there more microorganisms on a toilet seat or a door handle? How much difference does washing your hands really make? Place a clean finger and a dirty finger on the agar plate, which spot grows the most bacteria? Does the type of hand soap make any difference to the growth? Lots to test and do.
Age: 10 + with adult supervision
The kit contains Petri Dish, Nutrient Agar and activity leaflet.
