For our science experiment, we tried building mini igloos using different frozen materials to see which one would be the best. An igloo is a cosy little house made of ice blocks, often built by people who live in very snowy places. We froze three different mixtures—cornflour and water, jelly, and plain water—and then guessed which one would melt the fastest. Throughout the day, we watched carefully as each icy block began to melt.
The water melted quite quickly, the cornflour mixture kept its shape for a while and the jelly mixture remained stable and frozen for the longest time throughout the day. We used jugs to pour the melted mixture into to measure how much had melted.
By the end, we could see which frozen material lasted longest and would make the strongest igloo. It was a fun way to learn how different materials change when they warm up!

We decided that next time we conduct an experiment like this, we could change the conditions in which the igloos were kept. The children predicted that if we took them outside they might melt quicker because the sun is warm.
