Yesterday we went to the hall to see a science show because it is Science Week. The show was all about bubbles. We learnt about mixtures. Some things like oil and water don't want to mix. If you shake them up they will still separate. Other mixtures like baking soda and vinegar cause a reaction. The gas it produced blew up a balloon.
We also learnt about dry ice or carbon dioxide. You can't seal it in a container because it turns from a solid to a gas. Gasses take up more room than solids. Sealing it in a container will cause the container to explode. It can be very dangerous.
We saw several different bubble mixtures. The scientists made little bubbles, big bubbles and enormous bubbles. It was very exciting!
