10 January 2013!
Today was the first official lesson that we started to learn more about Chemistry. We started on the Chapter of Elements, Compounds and Mixtures! We did a class activity and were split into different groups of 3. Through this activity we learned how to classify the different particles into different categories based on our observation. There are many different ways to classify them, for example: same colour, same amount of particles, same shape etc. After completing that, we moved on to guess how other groups had classified the exact same set of particles. I think it was a very enriching experience, something that was new to me. Once we were done, we had to answer some questions on this activity:
1. Which one(s) do you think comes from the same type of substance? Why?
2. Which two do you think come from the same substance? Why?
3. Which one is/are gases?
4. What do you think each particle represents?
From answering the questions and asking questions, i also learned that when heat is introduced to do particles, the particles will move causing the atoms to be in a "distorted" manner instead of a uniform row. I also learned that the more number of particles occupying a certain space, the greater the density.
I asked a question: what is the difference between particles and atoms. Apparently, "particle" is a broad term for atoms and molecules.
That's all for today, thank you for reading!!
