Last term, the school's Integrated Learning topic was EXPLORATION.
In Room 5, we explored what happens when acids and bases are mixed, as well as the energy transformations that occur.
Using the common household acids and bases (ie. vinegar and baking soda), we had fun with some experiments. Some worked better than others but we didn't give up until we succeeded!
The bottle was half-filled with vinegar. A teaspoon of baking soda was placed into a tissue, then the tissue was carefully dropped inside the bottle. A cork was put over the top and, propped up by some pencils, the bottle was flipped over.
As the baking soda and vinegar mixed, a gas was released. This gas built up inside the bottle, increasing the pressure, and eventually BOOM! The bottle flew up into the air!
Here is a more successful attempt!
We invited our parents to school one afternoon in a Celebration of Learning. Our boards were all decorated with everything we learnt over the term. We also showed the parents our experiments and they were impressed with the results!
If you want to find out in more detail the different things we did on the day, visit our individual blogs. We were asked to create and share a slideshow about what we did.
The vinegar/baking soda experiment is really easy - have a go yourself!!
