In our Science inquiry this term, students are enjoying making a range of mixtures. So far in class they have conducted experiments with milk, soap and food colouring, have made slime and sparkly crystal stars. The Year 2s have also watched many explosive experiments resulting from mixing mints and Coke, and vinegar and Alka Seltzer. In Week 3, the Year 2s had an incursion with Hands On Science which was called Mixing Materials. During the incursion, students sorted materials into categories, explored the effects of adding gelatin to water and the impact of adding air to the gelatin mix. Students will be heading into the school kitchen next week to further their knowledge about how mixing substances can create delicious results.
Some comments from our Year 2 scientists:
When you mix things, you can make new substances. If you mix water and Alka Seltzer it makes a gas. If it is in a container with a lid it will go KABOOM! and explode. Rayner 2A
You can mix milk, soap and food colours. When the soap and the milk mix together they make the colours in the milk move into a beautiful rainbow. Daisy 2A
If you put a Mentos with Coke it will foam up. Will 2B
If you mix tablets in water, sometimes they will dissolve. James 2B
If you mix food colouring, glue and Borax the mixture gets slimy and sticky and you can make slime. Ivy 2B
We can mix Mentos and Coke and it will explode like a Coke volcano. The mixture makes a gas. Ziad 2A
ou can add things together to make new mixtures like water and flour in a cake. When you heat it up, the texture becomes different because of the heat. Shekynah 2A
You can put Mentos in a bottle of Coke, shake it really hard and it will explode. It will pop the lid off because of the extreme pressure caused by the gas. Mabi 2A
