Year 4 - Science Day!

Date: 18th Mar 2026 @ 1:28pm

We have absolutely loved Science Day today! We were given our investigation question, “Which temperature of tea is best for dunking biscuits?” then we had to plan the investigation and carry it out. We managed to sneak in a biscuit too! We found that warm tea (around 60–70°C) is ideal because it softened the biscuit just enough, so the biscuit absorbs tea quickly and gets that perfect “gooey but not collapsed” texture. Warm tea didn’t soften the biscuit quick enough and the cold/ice cold teas hardly softened the biscuit at all.

Afterwards, we went to a workshop in the hall where we took part in lots of different experiments with Rebecca. The first thing we looked at was circuits and how if a circuit breaks then our lights/buzzers wouldn’t work. Then we had a physics challenge where we had to use blowing to remove a cup from a stack. Afterwards, we used physics again to create a tornado type effect to get a sunken satsuma from the bottom of a water filled jug to the top.
