30 Mar A visit from a STEM Ambassador
The children in Year 2 were really excited to welcome John Poh, a STEM Ambassador, who works as a Senior Research Scientist for the UK Health Security Agency to Beddington Infants’ School. John shared lots of interesting pictures of science laboratories and talked about they could have a job as a scientist when they were older. He spoke to them about his role as a scientist and how scientists have helped in the response to COVID-19 in the United Kingdom.
After talking to the children about his job he demonstrated several scientific experiments. The children explored:
- creating fizz inflators – using the reaction between bicarbonate of soda and vinegar, to blow up a balloon.
- making an egg float in a salty solution
- chemical reactions between everyday substances
- creating lava lamps with oil and water
- Oobleck, a substance made from cornstarch and water
He also demonstrated how to make toothpaste, using hydrogen peroxide, a mild antiseptic used on the skin to prevent infection of minor cuts, scrapes, and burns.
This exciting day of science investigations built on the children’s experiences of being scientists as part of their Muck Mess and Mixtures topic and learning about scientists as part of British Science Week.
