I had seen at Target a creepy Petri-dish Jello set, however it looked really phoney. It had large gummy spiders and other large gummy things that you would not normally find under a microscope. This wasn't going to work if I wanted to blow these kids away. So I decided to start researching how to make the Petri dishes look more realistic. I started by ordering Petri-dishes off of homesciencetools.com. Once they arrived I got to work. I bought strawberry sugar-free jello (I find that it tastes the same as regular, and these students will have plenty of sugary cupcakes, cookies, and candy!, and went through my collection of sprinkles. I tried several different kind I came to the conclusion that black non-perils dissolve the best and really look like mold... Perfect!
The next trick was to make enough for the whole 4th grade!
- Plastic Petri-dishes
- Any red sugar-free Jello (one box makes about 25 dishes)
- sour gummy worms
- black non peril sprinkles
- Rinse out and air dry Petri-dishes
- Make jello according to package
- Lay out dishes on a cookie sheet or wire rack and fill
- Gently shake sprinkles into dishes, do not over do it. They will dissolve to look like mold, and if you have to many it just look like a black blob
- Let sit in fridge until solid. Keep refrigerated until ready to serve
My students went crazy for them! Hope yours do too!
