How many of these items do you already have? We’ve tried to keep it simple for you by making the majority of the items things most people have within reach (both physically and budget-wise), and even have broken down the materials by experiment category so you can decide if those are ones you want to do.


Here’s an easy way to decide which materials to get: look over the list, and if the group of materials seems to difficult to obtain, just skip it for now and go onto the next group within the unit. Most items are obtainable from the grocery store, hardware store, and online! You do not need to do ALL the experiments – just pick the ones you want to do!
