We love science class with Mr Yavor. He always has exciting science secrets to share with us – we explore polymers, electricity, we make volcanoes, and this week – crystals.
This is what you do to grow your own crystals. First we make the water take as much salt as possible and stir, stir, stir. Water cuts the small table salt crystals down to invisible pieces. When it can’t take any more salt, we have to make it still take more… by heating it. Heat gives extra energy to water so it dissolves the salt better. Once it starts cooling it wants to repel the salt. This is when the crystals form. We dip pipe cleaners in the hot salty water, and after some time our very own crop of crystals will form on the pipe cleaners. Can’t wait!
