      It was where alkali metals were shown to react with water.

      So for this experment we had a substitute teacher, and the experiment was set up to show how these metals reacted with water. So most of them produced fizzes or pops. But the potassium shattered the container of water. Or at least I think it was potassium. The teacher was meant to cut off a small amount of the metal, rather than put the whole cube of it in the water. I mention substitute teacher only because I think we all realised already that the other metals were being used in small amounts and the bangs were getting bigger, so to finish with a big lump was going to do something special. I do not think the teacher was a full time science teacher 🙂 was very good though.

      Memorable because it was the biggest bang we have seen at school

      Hi Izzy

      My most memorable science lesson was an A Level Chemistry lesson where we had to make Aspirin. I got to use a lot of equipment and chemicals I had never used before and it all went very well!

      Except that my aspirin was pink so the teacher refused to give me full marks. 🙁

      Not that I’m still bitter…

      I remember cutting up a frog in Biology! We had to take out the heart and the lungs.

      How gross is that?

      Hi Izzy!

      I think the most memorable science lesson I attended was a Physics lessons at high school, in which we did an experiment on diffraction of light using a laser. That was the fist time I used a laser in a science experiment. 🙂

      That lesson got me hooked on light and lasers. 🙂
