Science experiment: The chemistry of winter




Science experiment: The chemistry of winter

My sister and I belong to a science club called Mel science. We receive a chemistry set in the mailbox
each month. Last month’s set included “fake snow” and “snow on a tree”. We did the “snow on a tree”
experiment yesterday, and this is how it went.  

The experiment included tap water, hot water, table salt, potassium ferrocyanide, a paper tree, a beaker,
a pipet, a petri dish, a vial and liquid soap. 


First, we mixed the potassium ferrocyanide with the table salt. Then my mum poured some tap water into
the vial. Now my dad had to shake the vial extremely well. Next my dad put the vial into the hot water for
five minutes, after the five minutes where over he poured the mixture into the petri dish. We put the tree
into the petri dish, we left it for 12  hours. It amazed us at how it looked. Because it had fake snow all over
the tree!!! You might wonder how the snow got on the tree… Well, the tree sucked up the mixture the
same way a paper towel sucks up water. After the liquid mixture (now on the tree) dried out, it left only the
salt crystals. This is the “snow” that was on the tree! 

 


We looked at the salt crystals under the microscope, and this is what we saw.

  1. WOW Edmon, this experiment looks fantastic. It looks like you and Danielle had a great time doing it. It sounds so interesting and the result of the chemical reaction is very impressive. I really love the photo of you both wearing your safety glasses and gloves. Thank you for posting this on your blog!

  3. Your science experiments look like great fun and the salt crystals are amazing. The science club sounds very interesting. You will have to tell me more about this when we go back to school.
