Over the past few days, Mr Shanahan’s literacy group have had an awesome time looking at chemistry. We tested different substances and tried to find what 5 mystery powders were, depending on their reaction with our base. The first day, we took the 5 powders and smelt, touched and even tasted them to see what they were. Then we mixed them with vinegar and tried to identify them.
The next day we did a cool experiment with red cabbage and mystery powders 1 and 4. First we put cabbage leaves in a ziplock bag and added water. We mixed them together until the water turned a lovely purple/blue colour. Then we poured the water into a clear cup and put spoonfuls of it into our powders. Powder 1 made the water turn blue and made it less transparent unless there was more water. Powder 2 turned pink and created lots of bubbles that fizzed up and overflowed out of the cup!
We all loved our chemistry experiments, here some photos of the wonderful outcomes.
|Great job everyone. We all had a fantastic time learning about the world|
