This week the pupils had the chance to investigate different concentrations of foam bath mixed with water to see what would produce the optimum amount of bubbles whilst providing good value for money. Four of our STEM ambassadors attended the session and were very supportive of the year 3 and year 4 pupils as they had previously completed this investigation themselves. Lots of fun was had and once again the pupils were fully engaged in their task and worked co-operatively to whisk, shake, stir and blow their bubble mixture to produce an abundance of bubbles!
Freddie, on of our STEM ambassadors was also able to help me prepare our letter and water test strips to be posted off to relatives in different parts of the country to see whether how hard or soft their water is. This links back to an investigation done by the year 5/6 STEM Club prior to Christmas when we tested water samples from different sources within our school and confirmed that the water in our locality is hard and is responsible for the build up of limescale in kitchen appliances.
