Gene engineering! You can buy kits that will allow students to transform E coli bacteria with plasmids containing a gene from fluorescent jellyfish (GFP). While bacterial colonies that glow under UV light might not be the most dramatic sight, nothing beats being able to tell your friends "I genetically engineered an unnatural glowing creature in class today!"

but a reaction none the less!

for a biological reaction...
get hydrogen peroxide, chicken liver, raw potato, and a cooked potato

pour some hydrogen peroxide in a petrei spelled it wrong, i know dish, then put a piece of chicken liver in the dish, it will start breaking down the hydrogen peroxide, do the same for the cooked and raw potato

have your students record what broke down hydrogen peroxide the fastest, and why it did that

chicken liver, and potatoes have an enzyme that breaks down the hydrogen peroxide, if you destroy the enzyme (by cooking it) it won't do anything
