Science week took place this week in Scoil Mhuire.
We worked in small groups to make volcanoes using Paper Mache. We then painted the volcanoes and varnished them using PVA glue. The next step in our experiment was to attempt to make our volcanoes erupt!
Option 1: Coke and Mentos
Option 2: baking soda and vinegar
Pupils conducted the experiments and concluded that Option 2 worked better and created a chemical reaction strong enough to make the volcano erupt.
The next experiment conducted by the class was to make honeycomb. We mixed caster sugar and golden syrup together. We then added bicarbonate of soda. The bicarbonate of soda breaks down with heat to release carbon dioxide gas. The gas causes the sugar and syrup mixture to froth and bubble. The bubbles become trapped in the mixture where they set as the mixture cools. This gas is what makes the bubbles in the honeycomb. Of course we also conducted a taste test when the honeycomb had set!!
