Science Week in Class 5 Class 5 had a very busy and exciting science week last week. At the beginning of the week with Mrs Arnold children did a heart rate investigation in a PE lesson. They had the water bus workshop on Tuesday and they did the mentos and coke experiment which they had read about in a guided reading text. Later in the week children did a thermal conductivity investigation to finish their topic on properties and changes of materials. They also did a reaction times investigation, enjoyed spending money in the science gadget shop and enjoyed watching the very exciting Xplore science show on Friday.
