As part of our STEM week, we have carried out a number of Science and Technology activities in Year 5. This afternoon we realised that we could make a raw egg bounce after leaving it in vinegar for 48 hours. This happens because the acid in the vinegar eats away at the shell to expose the soft, bouncy membrane of the egg! We also created our own Volcanoes by mixing bicarbonate of soda, food colouring and vinegar!
