Drumcree Science Workshops - Week 3

This week we made crystals.  We used copper sulphate powder and diluted it in warm water.  We kept adding more powder until we had a saturated solution - no other powder could be dissolved, it just lay in the bottom of the beaker.  We then filtered the solution.  Next we heated the water using a bunsen burners.  When it had started to boil we removed it from the heat.  We tied a piece of thread around a small crystal.  This was ourseed crystal.  We let the seed crystal dangle into our water solution and hopefully a blue crystal will grow!
