science fly

Aim: To learn about flight and aerodynamics. 

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

Definition: the action of flying through the air or process.


4 forces of flight:

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

Paper Plane:

Material:

1. pepper
2. ruler

Steps:

1.  fold your pepper in half
2 fold each of the top comes into the center line 
3. fold the top into the center line.
4. fold each of the tops comes into the center line

Findings:

Plane Type	Distance	Behavior
Normal	2.7 meters	straight line
Ailerons	3.0 meters	curved
Paper clip	3.8 meters	straight line

Conclusion: 
At today science I have make a paper plan with my friend, and my normal paper plane was flying to 2.7 meters, then I was trying flying more distance with my ailerons plan then I get 3 meters, and at last, I use paper clip plan to flying 3.8 meters.
At today science I have learned four forces flight are thrust, drag, gravity, and weight, I also know if you use a paper clip to fly then you will get the distance one of normal, ailerons and paper clip.
The normal paper plane was the recent one, then ailerons were distance than the normal paper plane, also paper clip paper plane was more distance than the ailerons. So normal paper plane was the very recent one, then ailerons were the second recent one, and the paper clip paper plane was the distance one. because when I fly the normal paper plane there were some weight so the paper plane was going down, so normal paper plane was the recent one, because there were some thrust when I fly the ailerons paper plane so it was going distance, but ailerons paper plane was not the distance one, because there was some lift and thrust so when I fly the paper clip paper plane was the distance one in these three.

science

Aim: To see mix creates the most gas.

Hypothesis: (What do I think will happen)    

what I think is going to happen  that is vinegar and baking soda is going to make most gas, because if you shaking the baking soda and vinegar then the gas will make more, and  if you put it together then the water will 
Materials:

1.  warm water 
2.  sugar 2 Tsp
3.  bottle X3
4.  funnel
5.   balloon X3
6. vinegar 2 tsp
7. baking soda 
8. soda 
9. yeast 2 tsp
10. salt
11. soda water 

Steps:

1.  first, get a bottle from the bag and get a balloon and funnel
2.  put sugar and 2 tsp yeast in the bottle
3.  put warm water in the bottle
4.  quickly put a balloon on
5. second, get other bottle and balloon and funnel
6.  put 2 tsp vinegar in the bottle and baking soda in the bottle
7. put warm water in the bottle then put balloon on
8. third get the other bottle and a balloon and funnel 
9. put soda and 2 tsp yeast in the bottle 
10. put warm water in the bottle 
11.  then put a balloon on the battle 

My images:

Findings: if you put baking soda and vinegar together then the balloon made fast be big, but not so many bubbles in the bottle. if you put salt and soda in the bottle then the balloon made big slowly also I have found out carbon dioxide effect can make a difference to how big are the balloon.

	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 amount	small amount	large amount

Conclusion: 

• At balloon A we put 3 tsp baking soda, 1/2 cup vinegar in a bottle and we put warm water in there too.
• At balloon B we put 3 tsp salt, 1/2 cup soda and warm water in the other bottle
• At balloon C we put 2 tsp years, 1 tsp sugar and warm water put in another bottle 

At balloon A when we put a balloon on the bottle, the balloon was made balloon was so quickly also balloon A make big to 14.7 cm. At balloon B when we put a balloon on the bottle, the balloon was made big so slow and balloon B just make big to 8.6 cm. At balloon C when we put a balloon on the bottle, the balloon was made big slowly too but is faster then balloon B, also balloon C make big to 12.8 cm.

I have found out carbon dioxide effect can make a difference to how big are the balloon, also I have found out my hypothesis is correct, because my hypothesis is the only bigger one.

Jile get stuck a tree then people come help him

Hi guys
 Today we have draw a little story a word , and we also learn some different type of drawing.like close ups, establishing shot, tracking/panning...We didn't finish us story and we will finish next time, and we will make more clear at next time.

Skittles

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

Materials;

1. water 
2. petri dish
3. skittles

Process:

Step 1:Get skittles and petri dish from Mr Tisch.
Step 2:Put skittles in the petri dish.
Step 3:Put water in the petri dish.
Step 4:Then wait on minutes then the water will change the color.

Conclusion: What have I learnt from this experiment?
Today I have lear skittles also have chromatography, and everything that have chromatography, if you put in the water then the water will change the color.But don't drink the water.

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. water 

3. felt tip pens

4. chromatography

Process:

Step 1: copy and past Mr. Palmer's blog.
Step 2: Get a cup, chromatography paper and two felt tip pens

Step 3: Use two felt tip pens draw two dots on the chromatography paper.

Step 4: Put the chromatography paper in the cup then full the water in there.

Step 5: wait for ten minutes for the water soaked the chromatography paper, then when the water soaked the chromatography paper will change color. 

Conclusion: What have I learned from this experiment?

Chromatography paper was a magic paper because if you draw a dot on then get a cup and put some hot water in the cup then put the chromatography paper I there then wait ten minutes the chromatography paper will change color and chromatography also called rainbow paper. but you just can put hot water in, but if you put water in that is not going to work
   

clean the garden CIP

Hi guys
At today CIP we have did some clean in the garden and pick up some rubbish also I have find a blue rock in the garden,Then I was go to change the jop with Tyler, then I go to pave the ground.. also we need pick up some leaves. then we help each other do clean the garden., but we did'd finish, then Mr Mitchell said we can finish at 11:30-12:00.
                      

This is what we did at today CIP.

Aim: To learn the names of 10 household chemicals and identify if they are a solid, liquid or a gas.

Definitions:

1. Element; A single form of a chemical 
2. Compound: A mixture made up of 2 or more elements
3. Reaction: A process in which chemicals mix together to form a new substance.
4. Mixture: When two or more elements are mixed together.

Equipment:

1.     lemon juice
2.   salt
3.   sugar
4.   vinegar
5.  lemon bubbles 
6.   onion gas
7.   baking soda
8.  milk
9.  com flour 
10. banana

Steps:

1.search the name of each one
2.then put the image in the table
3.then find the name of each one acids name
4.then writ the name of each things acids on the table

Repeat the steps for all the chemicals.

Task 1: Put the 10 chemicals in a chart with the titles - Name, Chemical ingredient(s), Image, Solid/Liquid/Gas.

Name Chemical Inmage solid/liquid/gas Lemon juice Citric acid Liquid Salt Sodium Chloride Solid Sugar Aldonic acids Sold Vinegar Acetic acids Gas Lemon bubbles sodium bicarbonate Gas Onion gas Sulfenic acids Gas Baking solas Sodium hydrogen carbonate Sold Milk 2-Hydroxy propanoic acid Liquid com flour Amylum clearjel Sold Banana Malic acid Sold

CONCLUSION: Today we have Lear some information about sold,liquid and gas.so now I know banana,com flour,baking soda, sugar and salt are part of sold. Then milk, lemon are liquid and onion gas,lemon bubbles,vinegar are part of gas.
