Exploring fizzy reactions

November 19, 2019

In Science Club this week, we looked at fizzy reactions that take place when sherbet ‘flying saucers’, effervescent tablets and bath bombs are added to water. They contain sodium bicarbonate (baking soda) and acid, which react together to produce carbon dioxide gas and produce lots of fizzing and frothing. We mixed lemon juice (an acid) […]


Playdough

November 12, 2019

This week, Science Club have found how to turn flour into playdough.  To do this, we needed to make the starch granules in the flour expand and fall apart by heating them with boiling water. We mixed flour, salt, oil and a few other ingredients with the boiling water and watched the mixture thicken and […]


Spinning around

November 10, 2019

This week in Science Club we have been looking at how to make spinning tops. We looked carefully at some spinners to see how they were designed to produce a low amount of friction so that they could keep on spinning for a long time. The challenge was to investigate how we could make our […]
