## Science Motion Graphs

In science class we used motion sensor to show an object going nowhere, forward, backwards and zigzag. We then tried to match graphs with the motion stopper.

In this graph we stood in the same place.

In this graph we start far way from the motion detector  and moved closer at constant pace.

In this graph we started close to the motion detector and moved farther away at a constant speed.

In this graph we started close to the motion detector. We then moved away from the it and then came back to it quickly. We repeated this process of moving away and then coming in a few times.

In this graph we start away from the motion detector than walked towards it, then stopped for a few seconds. We then moved closer to the motion detector and stopped for a few seconds. Then we quickly walked away from the motion detector.

In this graph we started away from the motion detector and  moved closer. We then stopped for a few seconds and then continued to move forward. Then we stopped again for a few seconds and we moved quickly away from the motion detector

In this graph we start close to the motion detector and then quickly moved away from it. Then we stopped for a few seconds and moved closer to detector. Then we stopped for a few seconds again.

In this graph the machine glitched so we couldn’t do it correctly, however if we were we would have to be a medium distance away from the detector, then move farther away then come close quickly then stop for few seconds. Then move away again

## Science: Eye Dissection

How the Eye Works

Pupil: Gap for light waves to go through

Cornea: Protects the pupil and the iris, so that not to much light waves go through.

Iris: Ajust how big a gap the pupil is. When it is nightie the pupil is larger, because there is less light waves. When it is daytime the pupil is smaller, because more light waves are present.

Retina: Where light waves are projected  to create an image.

Optic Nerve: Where the image is sent to the brain

Brief Summary

Light waves hit your pupil and pass through it until it hits the lens where it is focused, where it is then projected onto the retina. From the retina the optic nerve sends the image to your  brain.
