Cow Eye Dissection

A.I.M - To look at a cow's eye and the main parts of the eye.

Equipment -

1. Eyeball
2. Scissors
3. Gloves
4. Tweezers

Method -
1. Remove the tissue before you start
2. Gently puncture the eye and cut around the cornea. ( DO NOT SQUEEZE )
3. Remove the humor from the eye
4. Cut the rest of the eye in half
5. Get rid of the retina

Investigating Light - Making Waves

In science today we were working on learning about light energy and how fast light travels. We had to learn about the differences between Transparent, Translucent, and Opaque. Here is my work.

1. Window - Transparent
2. Cloud - Translucent
3. Can of coke - Opaque
4. Mirror - Opaque
5. A dog - Opaque
6. A glass of milk - Opaque
7. Frosted glass - Translucent    
8. A desk - Opaque

1. Moon - No
2. Sun - Yes
3. Mirror ball - No
4. Match - Yes
5. Phone (cell) - Yes

What is the fastest way to travel through the universe?

A light.

What is the speed of light?

299 792 458 m

Define optical science?

Science and studies of lights.

What is fiber optics?

Thin pieces of glass/plastic that light pass through.

Name three instruments the help use see very small objects far away

1 - Telescope

2 - Microscope

3 - Binoculars

Hearing Test - Making Waves

A.I.M - To test my hearing.

Hypothesis -
That my hearing will be normal.

Methos -

1. Listen to the sound test
2. Record what my hearing level is.

Findings -
My hearing was in-between sorry, this test is for people, not bats or dogs and no way.

Conclusion -
 During the test, I was hearing the sound at the start. This means that my hearing is better than the average human.

Making Waves - Marshmallow Catapults

Definitions of scientific methods.

A.I.M - What you want to find out.

Hypothesis: An educated method guess.

Equipment/method: Material used for the experiment.

Conclusion: What you research and what you find out.

Steps: The order in which you carry out the experiment.

Findings: What you found out. ( not your friend )

EXPERIMENT

Hypothesis:

I don't think that it will shoot far at all.

Equipment:

1. 1 clean cup
2. 1 balloon
3. 1 pair of scissors
4. 1 marshmallow

Method:

1. Cut the bottom off the cup with the scissors.
2. Tie a knot at the neck of the balloon and snip off the tip.
3. Stretch the balloon over the top of the cup. You may find this a bit tricky to start with, but after making a few it becomes easy.
4. Pop your marshmallow into the cup.
5. Fire the missile by pulling the knotted neck of the balloon and letting go. You will be surprised at how far it can travel2
6. The open end will fold together when you stretch the balloon, but this will not stop the missile from firing.

Findings:

Our marshmallow catapult was able to shoot up to 11 of my feet when Tennessee shot it over the desk. When the elastic balloon was pulled back it stretched very far and the further the balloon went the more likely the marshmallow would go further.
