This morning in Year 1, we carried out an exciting experiment called Exploding Lunch Bag! The children were amazed as they watched a sealed bag suddenly pop. Using baking soda and vinegar, they observed how a chemical reaction created gas, causing the bag to expand until it burst. They discussed what was happening at each stage, making predictions and thinking scientifically about why the reaction occurred. Our Science Ambassador, Noah, was a fantastic helping hand during the experiment. Then we planted mung seeds in a sealed bag with moist cotton wool, the children came up with different suggestions about what might happen next. Some wondered whether the seeds would sprout faster in a warm or cool place and questioned if adding more water would speed up the growth. While others were eager to see if theirs would grow faster than Reception’s.
