Towards the end of the day we opened up our insulating chambers, gathered as a group and shared our plan and what was left of our ice. We made some great observations. We noticed that the ice that was surrounded with tin foil or had thin layers had melted more than the ice surrounded by paper towel or thick layers. We will be using what we observed during our testing phase to make changes to our plan.
We’ve been busy using the design thinking process while designing and creating an insulating chamber to prevent ice from melting. To get us thinking, we sketched our ideas and then shared them with our group members. We needed to consider multiple factors when planning (for example: what causes matter to change state? And what materials contain cold air and keep warm temperatures out?) Together, we needed to agree on and sketch a final plan. Our next step was to start building and it was exciting to watch our plans come to life. It didn’t take long to surround our ice with our designed insulating chamber. We then needed to wait patiently. An interesting conversation about particles popped up while we were planning. We know that ice is a solid that has a definite shape because the particles are tightly packed. But the minute the temperature in the room causes the ice to melt, the liquid loses its shape. We were curious about where that liquid would go with all of the layers surrounding the ice cube. Some of us chose to contain that liquid in a Ziploc bag before starting. Others used a layer of paper towel to collect that moisture.
