( Pictures of my experiment! ^^ )
2/4/2014 Wednesday:
The first lesson was Science. We went to the Science lab after the dismissal in Parade Square. Instead of Mr Oon, Ms Yeo took charge of his place, with Mr Oon at the side of the lab. Ms Yeo gone through with us about the Chapter 5: Seperation of Mixtures.
After the briefing from Ms Yeo, we started on an experiment from Activity 1, called "Exploring Solutions and Suspension" . We took a lot of photos as we experiment and found out which substances are solute, solvent, solution or suspension.
After the experiment. I learnt that some kinds of tablets can form many air bubbles, such example is the Alka Seltzer tablet, althought I have never heard of this tablet and I wish to know what it is for. I learnt that corn flour is considered suspension when I notice it became 2 layers/more than 1 layer, when I learnt that it is considered suspension from Chapter 5 core notes, where I have learnt that it means the substance is insoluble/cannot dissolve, I wondered how we were able to drink something that is not at all able to dissolve...
If I have the the materials/substances, I hope that I can experiment on more types of these substances and find out if they are solute, solvent, solution or suspension, and what chemical reaction are produced and when combined, this will be really exciting!
