EyeBall Dissection Recount and Reflection

 Hey everyone welcome back yesterday In Hurumanu 4 We did a eye dissection I hope you enjoy have a wonderful day, Good-Bye 

Through out the lesson we were Dissecting they eye some of the things we came across were the lens the pupil the cornea ect. 

What all the Eye parts do 

Cornea- The protection layer on the outer of the eye

Pupil-Where the Light enters the eye

Iris-The Focuses light onto the Retina

Rentina- Converts light to electrical impulses

Optic Nerve -Carries the impules to the brain 

Humorus-The Liquid in the eye that gives it the shape 

To start of the dissection we had to take the fat of around the eye, and then once we had done that we had to cut into the cornea which was very difficult because since the cornea is a tough part to get to because it protects your eye, once we got through we had to be really careful because the humor/Humorus was coming out so we had to when we were cutting around we had to be really careful so that it didn't squirt on us other wise we would smell, once we got through the eye and got to the main insides we say the lens which had a liquid around it and it was a small ball looking shape that was the lens, and we saw the Tapedum which is what helps you see and it is a pretty blue colour. 

I Enjoyed Dissecting the eye it was really fun and it helped us learn many more things about a eye

Just a warning this may gross some out.

Energy transformations

 Hey everyone welcome back today we were looking at energy transformation I hope you enjoy my blog post have a wonderful day, Good-Bye 

What is energy transformations?

It is when energy is passed from one type to another.

There are eight types of energy these are the energy's

1. Kinetic- it is what makes things move

2. Chemical Potential- It is the energy from food and fuel 

3.Heat- It is the amount of energy based on temperature 

4. Light- Waves that are reflected so that is what makes you see light 

5. Gravitational- Its the effect of gravity pushing down 

6. Elastic potential- It is anything that you can stretch so it loads up with energy 

7. Electrical-Anything that used power 

8. Sound- waves can hear 

Marshmallow cannons

steps

Step 1. Cut the base out of a cup

Step 2. Stretch a balloon 

Step 3. 1/2 way down the balloon neck cut it 

Put the balloon over where you cut the hole. 

Then enjoy using your Marshmallow cannon 

What energy's were used. 

The energy's that were used where 

Sound energy - This energy was used by when we pulled the balloon and let go it made a big bang 

Elastic energy- We used elastic energy because we had to stretch the balloon out

Gravitational potential -Gravitational was used because when the marshmallow fell down it was gravity pulling it down 

Kinetic- This one was used by when the marshmallow was moving 

What we did the them 

We took our cannons out side and launched the balloons with the marshmallows in them 

Here is what we learnt about energy as a animation when we used the cannons
