We had a jam-packed, fun-filled day at Catalyst! The children used data-loggers to investigate changes in their surroundings, specifically recording temperature. We looked at hand-warmers and tried to keep them hot! By changing the surroundings of the hand-warmers, wrapping them in different materials, we investigated which might be a better material for an artic sleeping bag. We learned how this is CHANGING A VARIABLE.
We also learned about endothermic and exothermic reactions.
Endothermic reactions are reactions that take in energy from the surroundings.
Exothermic reactions are reactions that transfer energy to the surroundings.
In the afternoon, we worked in the observatory and investigated Halton. We learned about the history of the area, from Anglo-Saxon and Viking time to the present day. We looked at the various ways people have crossed the River Mersey over hundreds of years. We used iPads to deepen our knowledge and understanding of the past.
We also had time to play on a wonderful play area! Many thanks to Mr. Dewar, in helping us all on the slide.
