Science (Flight)

FLIGHT

Aim: To learn about flight and aerodynamics. 

• In your groups of 3 you will make a paper plane and measure its distance and behaviour.
• In groups of 3 you will make a water rocket and record its distance and behaviour. 

Definition:
the action or process of flying through the air

4 forces of flight:

1.   Gravity
2.   Thrust
3.   Drag
4.   Lift

Paper Plane:

Material:

1. Paper x1
2. Paper clip x1
3. Ruler x1
4. scissors x1

Steps:

1. fold in half and make a cress line
2.  unfold paper
3. fold two corners into the cress line
4. fold paper vertically in half5. fold paper landscape in half
6. flip paper over
7. fold two wings on both sides

Findings:

Plane Type	Distance	Behaviour
Normal	3.8 meters	straight
Ailerons	2.8 meters	swooped
Paper clip	3.1 meters	straight

Conclusion:
The four forces of gravity are: Gravity, Thrust, Drag and Lift.
We also found out how what you do to things change the way the react in the air.
When we did nothing to the plane it went to furthest, the plane also went straight. It went 3.8 meters. This was because the plane had nothing done to it.
When we added Ailerons to the plane the plane didn't do that far , the plane went swooped. It went 2.8 meters. This was because the ailerons was like a brake and slowed the plane down.
When we added a paper clip to the tip of the plane it wasn't the furthest but not the least furthest, it went straight through the air. It went 3.1 meters. This was because the plane was pulled down by the paper clip.
The normal plane went the furthest. The plane with the paper clip was second and the plane with ailerons went the least furthest.

Science

Aim: To see which chemical 
mix creates the most gas.

Hypothesis: (What do I think will happen)
I think that the vinegar and baking soda will make the balloon blow up the most because when you mix them the as rises so that's why I think that


Materials:

1. 3 Bottles
2. 3 Balloon
3. Baking soda 3 tsp
4.  Vinegar 1/2 a cup
5.  Salt 3 tsp
6.  Soda water 1/2 a cup
7. Yeast 2 tsp
8. Sugar 1 tsp
9. Warm Water
10. Funnel

Steps:

1.  Get 3 balloons and three bottles
2.  Add Yeast, Sugar and warm water in one bottle using the funnel. 
3.  Add vinegar and baking soda in another bottle using the funnel (but the baking soda in the balloon first)
4.  Add Salt and Soda water into a bottle using funnel.
5.  Put balloons on top of bottle.
6.  Wait for the results ( this my take unto an hour

My images:

Findings:

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)	Balloon 3 ( 2 tsp yeast, 1 tsp sugar )
Balloon Size (cm)	14.7 cm	8.6 cm	12.8 cm
Bubbles	Small amounts	Small amounts	Large amounts

Conclusion:

I have learnt that carbon dioxide affect can make a different to how big a balloon grows.

This is because the carbon dioxide make air that goes up and the balloon grows.

I have also learnt that when chemical react to each other it make carbon dioxide.

The yeast and sugar was the one that took the longest but still not the one that was the biggest balloon size. It was the one that had the most bubbles as there where lots of them.

The Baking soda and vinegar was the one that went up the quickest and the largest. But it had no bubbles at all.

The salt and soda water where the one with the smallest size and the least amount of bubbles.

I have found out that my hypothesis is correct because it was the bigger

Art Hurumanu: Stop Write Hear

Hi guys
Today in class we made storyboards for art to help us out with what will be doing in Art Hurumanu.
Here is the storyboards our group made:

We got given feedback on our storyboard the feedback we got was: It was good because it have lots of detail. Next time to write clearer so they could read it. explain whats going on better so they can understand.

It was really interesting to see what others think about what we have done and how we can make it better for next time.

It was a really fun lesson overall and I cant wait to find out what we are doing next.

Science 3

Skittles

Aim: To separate colours from skittles by using the chromatography.

Materials;

1. Skittles
2. Petri dish
3. Water

Process:

Step 1: Get five skittles and put them into a petri dish
Step 2: After that spread the five skittles out into a star shape

Step 3: Add water to the skittles.
Step 4: Wait a few minutes until you see the different

Conclusion: What have I learnt from this experiment?

I have learnt that when you add skittles to water the colour of the water changes because the colours of the skittles get put into the water.
This is also like what we did with the paper.

Science

Aim: To separate colours by using the process of chromatography.

Definition: Chromatography is a method of separating out materials from a mixture.

Eg. blood, ink, drugs,

Scenario

A crime has been committed. The police have a signed cheque and a letter from the same crime scene but it seems like the handwriting is different. They have 3 suspects but not enough evidence. They need to know if the letter and the cheque were written by the same person.

How do they tell if the pens used for both of these pieces of evidence are the same?

Rainbow paper

Materials;

1. Cup

2. Chromatography paper

3. Felt tip pens

4. Water

Process:

Step 1: draw on two dots 1 cm up from the bottom of the paper. 

Step 2: fold the paper onto to side of the cup so it isn't touching the bottom of the cup.

Step 3: slowly pore hot water into the cup until it is just touching the felt markings.

Step 4: wait ten minutes until the water is full soaked in.

Step 5:After ten minutes you will start to see the paper change colors because of the felt tip pens.

Step 6: Take out paper and then look at the rainbow color made.

Conclusion: What have I learnt from this experiment?

Today we learnt that chromatography is a form of science that the police even use to help with investigations.
It also can be used for fun and the reason why the reactions happen is because the ink reacts and the color goes up the paper with the water so it make a colorful rainbow.

Steps:

1. Find the name of a ingredient at home
2. Find the chemical name
3. Find a image
4. Find out if it is a solid/liquid/gas

The common name is baking soda, the chemical name is sodium bicarbonate an its a solid.

The common name is Milk, the chemical name is lactic acid and its a liquid.
