Hi, I’m Shayna. Today I’m going to tell you about my first science unit investigating light.

First, we learned about natural and artificial light. Natural light is light that is NATURAL, literally in the name. Artificial light is light that was man-made.

Now I’m going to talk about luminous and nonluminous. When an object emits light it’s called luminous and when an object reflects light from different types of light is called nonluminous. Here is a picture of my work.

What happens if something blocking the travel path of light? (Also Transparent, Translucent, and opaque)

It depends if the object is transparent, translucent, or opaque. Wait a minute?! I haven’t told you about transparent, translucent, and opaque! Before I tell you, by the way if an object is opaque, and something blocking the travel path of light, it will form a shadow. If the object is Transparent or Translucent, the light will go through the object. Now I will tell you about transparent, translucent, and opaque. You probably don’t understand what I’m saying. Transparent is when there is an object that you can see through. For example, Glass is transparent. You look out your glass window every day. Translucent is when there is an object that you can kind of see through the object. For example, an empty bottle of wine, or a stained window. You can only see a little bit through the object. Now for opaque. Opaque is when there is an object that you completely can’t see through. for example, every day toys like stuffed animals, toy cars, etc..  Here is a GIANT picture of my transparent, translucent, and opaque window.

Reflection

Reflection is when light bounces of of a surface. Here is an example picture of a reflective object. This is a mirror. This mirror is made for reflecting.

Refraction

Refraction is when light bends. For example, in this picture I have a cup of water, and I put a pencil in the it. The light bends when the pencil is in the water. Light travels slower in water. Look at the pencil. the pencil is bigger in the water and when the pencil is out of the water the pencil is smaller.

Reflection Of Learning

So far I think I am doing a great job in science!  I want to improve a lot this year. I am so exited to learn more through out the year! I think this year is going really well. I got my first science quiz, my math quiz, and my French quizzes. I think all of the subjects are going well. I would really like to learn about the human body later this year.

That concludes my post.
