Four out of our five classes had a very exciting visit from a STEM ambassador. Dave Rockett, who is an engineer for Northern Gas Networks, visited Owls and Kingfisher classes. He talked about climate change and what we can do to help. One such possibility is using hydrogen to replace some natural gas. Everyone was able to make some hydrogen from water in the classroom! Then they designed a gas network using straws to deliver their new gas to homes.  The children in Key Stage One had the opportunity to think about insulation in homes and they tried out different ways of keeping a beaker of water warm.  Dave also found time to have a chat to our Eco-warriors who are taking a lead on making the school more environmentally friendly.
