Science class #1-Crystals

 In my first science class I discussed what crystals are and how they are formed. We talked about common crystals (salt, gemstones, sugar).We went over a printout of the different shapes of crystals.

We looked at large quartz crystals as well as salt, sea salt, Epsom salt, sugar and alum under a viewing microscope.

I explained what a super saturated solution was and we all made one using Epsom salt and warm water.

Using our solutions we made sheet crystals on a glass pan.

I sent home instructions on how to make a big crystal, crystal needles and rock candy .

I also sent home this list of links:http://www.chemistry.co.nz/crystals_defined.htm
