Borax crystals

Postby Ajriggs600 » Tue Oct 30, 2018 12:58 pm

Hi my son is working on the crazy crystal creations experiment and I’m finding it hard to get numerical data about the crystals. How do you get the size of an individual crystal? The length was basically the same in all three environments because it was the length of string submerged in solution. The width of crystal size was thinner at top and got larger as it went down in all of them. So I’m stumped on info to use for bar or line graph. Any help would be appreciated!!!

Hello and welcome to Science Buddies,

Could you measure the width of each crystal at the point where the width is widest? Then you could plot the width for each of the methods you used for growing the crystals, with three (or more) experiments for each method.

You might also try to measure the length at the widest point.

Let us know how this works out! And be sure to let us know if you have more questions.
