Reflection of my growth development in Science

Science has really benefitted me through these years, and that it had developed an interest into me. This year, we have learnt on various topics, such as chemistry-atom structure,reactions , physic-reflection and refraction,colours of light, lenses, and biology-ecology,sexual reproduction.

It was fairly easy to learn these topics , although I still faced various difficulties at the start. When we first started on these topics, many questions were in my head. Like, why did that happen? how does it happen? However, this was quickly resolved as I had asked our teacher, and also conducted my own research. The hardest topic I found was reflection and refraction. This was because at the start, I did not grasp the concept, and had to inquire a lot about it to understand the reason behind it. However, after that, it was fairly simple to understand the other related topics on colours of light and lenses.

Other than that, biology was a new topic that we were taught on. Ecology was fairly simple, but there was a lot of information to learn about. Therefore, I feel that my progress is still decent, and that my growth development in science is still ok.

Term test reuslts and reflection

This term, I did quite well for my science and have managed to acheive an A1 for science. The topics tested were colours of light, lenses, and ecology. This was fairly easy once I understood the concept, and after revising, the test was managable to complete. I have learnt a lot about these topics, and am very interested after it was taught. I also conducted my own research on such topics to understand further about it. However, I should not take science as a simple subject and be arrogant about it, and that I would definately continue this good progress. My goal now is to maintain this A1 result in EOY, and my progress would be to start my revision now, during the September holiday.

Colours of light-Wavelength

When light travels through a prism, it would disperse into the different colours of light. Red, orange, yellow, green, blue, indigo, violet. The white light would disperse into a visible spectrum of light, containing the colours of the rainbow. This is because of the refraction of the lights. The lights are refracted at different angles, resulting in the spectrum.

This made me wonder, why would it be refracted at different angles?

This is due to the different wavelengths. As red has a greater wavelength of 700mm, it would travel faster than the other colours, and thus be refracted least. While indigo has a wavelength of 400mm, it travels the slowest, and thus be refracted more. This would result in the dispersion of light. As light passes the different mediums of air to glass, the reduce in speed causes refraction. At different speeds, the different colour lights would be refracted at different angles, resulting in a visible spectrum.
