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.

To grown your own crystal rainbow you will need to first decide if you are makin a complete rainbow semis circle or just the arch we typically see.

For making a complete rainbow you will line up a red, orange, yellow, green, light blue, dark blue /purple pipe cleaner. Tie a piece of yarn or string around the end to secure them together. If you are making a half rainbow arch you will cut your chenille sticks in half and then line them up as above and once again tie a strng around the end.
