Kia ora, everybody.
Today we would usually go to tech, but because school's are in lock down I have had to do technology from home. For technology we had to look at videos and gather as much information as we could about physical changes and chemical changes. An example of a physical change is if you put a mentos inside a coke bottle it will fizz and create carbon dioxide but it is a physical change because the carbon dioxide was already in their so their was no substance. A chemical change is when you mix things together and it creates a substance like if you mix a gummy bear and hydroxide together it would create a gas which would be a substance. So when learning about these I had to pick an experiment to do and I chose the colourful milk one. I think this experiment was a physical change because there was no substance created.
please enjoy my video.
Hi Greer,
ReplyDeleteI love your video, you have clearly explained the process for this experiment. I like that you have used what you have been learning about changes in matter in your post. Did you get to try any of the other experiments?
Take care

Hi Greer,
ReplyDeleteI enjoyed the video, I also tried this and got the same results. I loved all the colours and the designs it made. Did you do any other experiments?
Thanks for sharing.
