Evaluation

During our C.O.W time today we were working on making a Comic Life about Evaluation. Let us know what you think of our creations!!!!!!

Why do we have sunsets?

Today in theme we were investigating why the sun makes the colours it does when it goes up and down. We did an experiment to investigate this.

Aim: To find out why the Sun makes different colours when going up and down (sunset and sunrise)

Equipment: A glass, a torch or overhead projector, a spoon, water, milk a sheet of white paper.

Method:

1. Fill the glass with water and stand it in front of the white paper.
2. Shine the torch through the side of the water-filled glass in the direction of the paper.
3. Observe what light strikes the paper. What colour is the light?
4. Add a few drops of milk to the glass and stir through ( Don't add too much milk - just enough to make the water slightly cloudy)
5. Shine the torch through the side of the glass like in step 2.
6. Observe what light strikes the paper, what colour is it now?
7. What does this mean for us on Earth?

What happened?
The water with no milk in it reflected clear onto the screen. The milky water reflected orange onto the screen.

What this means for us on Earth?
White light is a mixture of all of the colours in the spectrum. when you sine white light through a jar of milky water. The tiny milk particles scatter the blue light in all directions, and so not much of this blue light ends up striking the paper. This effect is called Rayleigh Scattering. Red light is not effected in this way. Instead it passes through the milk and can be seen as a bright orange tint on the paper behind the glass.

Rayleigh Scattering also causes Sunsets. During a sunset only the red and orange light rays get through the atmosphere directly. All blue colours are scattering by tiny particles of dust in the atmosphere. The Sun and sky therefore appear reddish orange and they light up the clouds in the same colour.

Forces

Today in theme we investigated the different forces on the Earth.

Aim: To find out why and how we stay on Earth

Equipment: Ourselves, bucket, and water.

Method:

1. Fill bucket 1/2 way with water.
2. Pick up bucket with dominant arm.
3. Swing bucket around body like doing freestyle as fast as you can.

What happened:
The water stayed in the bucket because we spun the bucket and the force kept the water at the bottom of the bucket.

How this affects us on Earth:

• The Earth is covered in water.
• The Earth is spinning on its axis.
• That is why we have gravity.

Gravity is the force that keeps us on the ground!!!!

'What goes up, must come down!!!'

Earth, Moon and the Stars

Moon

If the Moon blows up what will happen to the Earth?

We would have seriously reduced tides, by almost two-thirds. The tide cycles are important for the sustaining of various kinds of life along Earth's shores.

The Moon

Do they still have the flag on the moon?
There is a 50% chance the flag is still on the Moon.

How old is the earth?

How old is the Earth. ?

the Earth is 54 billion years old.

Earth, Moon and Sun

In Room 10 we have been learning how the Sun and the Moon affect us on Earth. We have learned that:

• the moon takes 29 and 1/3 days to make one orbit around the Earth.
• it takes the Earth 365.24 days to orbit around the Sun.
• it takes 24 hours for the Earth to rotate once on its axis

This is why we have years, months and days.

We had a play with balls to show how the Earth, Sun and Moon are related.
Staring:
Sam: Sun
Peter: Moon
Kaea: Earth

PLUTO

How cold is Pluto?

Pluto is around about -240 degrees Celsius,

that is so cold that nobody can get to it without freezing to death.

MARS

Is there life on Mars?

No there is no life on Mars but there is life on Earth.

Speech Finals 2010

I was shaking so bad, I was about to burst. I kept saying to my self "It's time, it's time for me to shine and represent Lytton Street School. My family was supporting me and others, suddenly my name was called! Hey it's finished it was not bad at all, it felt good to be representing my school. Now one thing to do 3,2,1 now the nerves were back. The announcer said "3rd is someone from North Street School." I still have a chance to be number one. Aaaaaa! Oh my gosh they said my name for first. I came first equal with a boy from Saint Josephs. What a great night that was.

Term 4

Welcome back everyone!!!! What a great start to a busy term. I hope everyone had a great break and you are feeling refreshed for the last term of 2010!!!!

There is lots going on this term. Please make sure you bring appropriate footwear and clothing for cross country and athletics practice. Remember Cross country isn't far away now so if you are a serious competitor this year try and do some training in your own time.

Our big idea for the term is evaluation. Please think carefully about what you would like to achieve this term and what I can do to help you achieve your goals. Remember to make your goals realistic and achievable.

We are going to be looking at planet earth and beyond so have a think about what you know and what you would like to find out.

It's going to be a busy but enjoyable term. Let's keep the momentum going from day 1!!!!!!

Miss Main :)

Challenge!

See if you can work out what song this is. Leave a comment with your guess :)

Production

Last week the whole school was involved in our amazing production, Chocolate Fish, Gumboots and Number 8 Wire. It was a variety show that showcased kiwiana at its best. Our class item was a dance to the gumboot song. Here are some of the photos from the show.

Thank you to all of the parents and other family members that came to support Lytton Street School.
