Hello people it is me ethant36 and today I will tell you about my first unit in science, light.
Our first thing was natural vs artificial light and then luminous (object that makes its own light) and non luminous (object that can’t make its own light) and their meaning.
Then we did an experiment about how light travels. The point of the experiment was to find out if light travels in straight lines.
Then we learned about reflecting light and which materials are good reflectors. We learned what secular (smooth and good for reflecting) and diffuse (Bumpy and bad for reflecting)mean and transparent, translucent and opaque meanings and then refraction (where light appears to be somewhere that it is not because light moves more slowly in water than air). That was our first science unit that we did in grade four.
Here is what I learned: I learned about refraction, how light travels, and reflection.
For our next science unit I want to learn about simple machines.
Science is fun!
Here are some pictures of experiments
