Aerodynamics Flight - Science.

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 study of the properties of moving air and the interaction between the air and solid bodies moving through it.

4 forces of flight:

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

Paper Plane:

Material:

1. Paper
2. Large amount of space

Steps:

1.  Fold the paper in half 
2.  Create tringles shape up the top that lines up with the line down the middle.
3.  Then do the rest like the nomarl paper plane and your finshed.

Findings:

Plane Type	Distance	Behaviour
Normal	4m	Curved to the side.
Ailerons	4.2m	It used gavity and pulled to the ground at the end.
Rudder	2.8m	It dropped as soon as I threw it.

Conclusion:
Today we did a different experiment. We did a paper plane experiment . What we did was create a paper plane them use different stratgies each time we measured how far the plane goes. This experiment was a bit boring but it was okay making the paper planes. I thought the paper plane was going to be in a straight line but it curved to the side. 

Rainbow paper- Sciences

Today D.S and my class S.H, we did our first experiment but it was only a little experiment. I really enjoy doing this experiment and I really like how the water based pens went up and it was mixing different colours.We was using green and blue but it mixed into a pink and purple, I really like how it did that. 


Rainbow Paper

 

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

 

 Materials:

1. Filter paper

2. Water based felt pens.

3. Ruler

4. Cup

5. Water

6. pencil

 

Process:

Step 1: Rule 1 cm on the paper

Step 2: Draw a slight line on the paper and add two dots using the water felt pen.

Step 3: Get the plastic cup and the paper in there with the dots at the bottom but not touching

Step 4: Add a little bit of water

Step 5: Fold the top of the paper

Step 6: Wait and see what happens

This is what happened.

Conclusion: What have I learnt from this experiment?

Today with this experiment I learnt different materials. I just realise that water based felt pens are actually real

thing. Also at the start we only used 2 colours, we used blue and green but in the end it ended up changing

into other colours like pink and purple. I really enjoyed watching the colours smudge together making

different colours, and also was moving in different directions and speeds.

Household ingredients

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

Equipment 

1. Soap

2. Lemon Juice

3. Salt

4. Sugar

5. Vinegar

6. Milk

7. Onion Gas

8. Bleach

9. Baking Soda 

10. Lemonade

Steps

1.
2.
3.

4.

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	image	solid/liquid/gas
Soap	Fatty acid		Solid
Lemon Juice	Citric Acid		Solid
Salt	Sodium Chloride		Solid
Sugar	carbohydrates		Liquid
Vinegar	Acetic Acid		Liquid
Milk	Milkfat globules
Onion Gas	Lachrymal- factor		Solid
Bleach	Sodium hypocrite		Liquid
Baking Soda	sodium bicarbonate		Solid
Lemonade	Citric Acid		Solid

Conclusion

I learn't that Lemonade is a solid because I didn't know that And baking soda for the INGREDIENT had sodium bicarbonate in it.
