What we are currently doing in Science and why I think Science is interesting :)

My Blog Post on Science

By Faith Santiago

In this blog post, I will be talking about what my class and I are learning in Science and why I think it is interesting.

In Science, we are continuing our unit in Particle Theory of Matter. Specifically, this past week, we’ve been learning about Separation Techniques and Factors that affect the solubility of a solute. To elaborate, Separation techniques are used to separate pure substances (which are substances consisting of only one type of particle) from raw materials or other materials to create new products or mixtures. There are 5 methods of separation that we learned about. The first is magnetism. Since metals are attracted to magnets, you could use magnets to remove metals from non-metals. The second is Filtration/Sifting. This method uses the property of size. If the parts of the mixture are different sizes, you can use a device that separates the smaller particles from the larger ones called a sieve or a strainer. The third method is Evaporation. As we have already studied in grade 7, Evaporation is when a liquid turns to gas after reaching its boiling point. By this, the liquid portion evaporates and the solid portion of the solution is left behind. The fourth method is distillation. In this method, the liquid portion of the liquid is heated to its boiling point, evaporates, leaving the solid behind. Then the evaporated liquid, now a gas, travels through a tube with cold water coming in it to condense it back into a liquid. When this process is finished, you now have two separate substances. The fifth and final method is Chromatography, which uses the property of absorption rate to separate different coloured substances from a solution. If you were to dip paper with some colour along the bottom of it in water, the water would move up and carry the different colours along with it.

Now, moving on to why I think Science is interesting. I think Science is interesting because it makes you analyze situations really carefully and use logic and reasoning as to why things happen and how they world. It helps broaden my understanding of the world. It is fun to learn all the Scientific Terms and do experiments. It satisfies my curiosity of the world and makes me want to learn even more. I also like it because it is what I need if I want to become a dentist, which I have aspired to be since I was little. I have already planned to take biochemistry in university. This is why I am making the most of my experience of learning Science, since hopefully studying it will help me reach my goal.
