Rainbow Activities

Building your own rainbow is a fun STEAM activity. That means this activity combines science, engineering, and art for a truly educational and FUN learning activity!¬† So how does the science part work? You will be making a saturated soluiotn – it means the solution (water) is filled with as much powder (borax) as it can hold. The hotter the water the more of the solution can be completely mixed in and dissolved. Hot water makes the moecules move away from one another so the borax can join the party LOL.¬† Cold water means close together molicules that don’t have room to absorb as much borax.¬† The particles (borax) will settle on the pipe cleaners as it cools and pulls back out of the water forming crystals.
