Ice explorations- Balloon Fun!

This week we had a wide range of weather. It ranged from minus -40C to -5C. We took this opportunity to explore how the temperature effects different items. This post is about how we ‘Looked Closely’ at balloons and the effects of temperature on water inside a balloon. We filled balloons with water and placed them outdoors for four hours. The student made some predictions about what would happen. Some wondered if they would float away, freeze or stay the same. We brought the balloons inside and in small groups the children explored the balloon. Some balloons sprung a leak right away. Some balloons popped and some needed to be cut open in order to explore what was inside. One student realized that the ice inside was sharp and when they squished the balloon the ice caught the side of the baloon and ripped it. The water had formed an outside layer of ice. The students were surprised to see the shape of the ice. One group learners that ice melts in our hands because our hands are warm. We added food colouring to the ice and watched the changes. We also made predictions on colour changes when other colours were added to the ice. It is so interesting watching these young scientists ask questions, explore and make conclusions.

At home you could extend this experiment by freezing water inside balloons for different times and comparing the effects of time and temperature on balloons.

    Thanks for sharing this, Angie! What a great experiment and what a wonderful way to get students excited about sharing and questioning. I just shared your post with a Grade 2 teacher at my school. I know that the Grade 2’s are working on matter and the water cycle, and this activity could possibly connect. I bet that even the older students would love it!
