6th grade science covers how science works to explore the natural world, general science facts, science history, and how science affects everyday life and society. Take this ten question multiple choice quiz to see if you understand these concepts at the 6th grade educational level.

- The speed of light in a vacuum is constant.
- For every action, there is an equal and opposite reaction.
- A body in motion stays in motion or a body at rest stays at rest, unless a force acts upon it.
(2) You see your image in a mirror because:
- light bouncing off your face is refracted by the mirror
- light bouncing off your face is absorbed by the mirror
- light bouncing off your face is diffracted by the mirror
- light bouncing off your face is reflected by the mirror

May I use some of your pictures that you posted for the elements of the periodic table in an informational video for my science class? I would be really grateful if you allowed me to. I will site my source so you get credit.
Yes, thanks for asking 🙂
This makes my life better and thanks for asking. 😀
