Week of 10\5-10/8

This week was very short because we didn't have school on Friday. We foused on Newton and Huygens hypothesis. In the beginning of the week we had to read a article about Waves and Particles. Isaac Newton had a theory that light is made of corpuscles (meaning "little bodies"). On the other hand, Christiaan Huygens had a theory of that light is made up of waves.

Lets start with Isaac Newtons theory of light. He says when the particles of light go into the medium then they shift a little bit downward. In which the force pulls the particles down the to the right. But, for Huygens he says there are waves that a pulled into the medium then it bends when its into the medium and when it exits it bends again. I said that Newton was corrected because the particles could be correct because particles are in everything. There in light, gases, liquids, etc. But, then the waves could be correct because instead of particles flowing around there are force pulling the waves to a surface or gas. The example of when you throw a stone into a lake there are waves coming off. But, when you breathe in the cold there are particles coming out so you can see your breathe. In the end the article says that both of the theorys are correct. They both work for different things and one can't work for the other and visa versa.

The science ideas I've learned this week is that even though two or more hypothesis are trying to state one topic, doesn't mean they both can state the topic. It doesn't always have to be one and only one real answer. The real world application for this lesson is like I said if you are a scientists and want to see how many waves a huge rock makes in the water. Or maybe who many waves does a small rock do. You can use Huygens experiment. And you will find your answer.
