Aerodynamics chemistry work

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:
According to Google:

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.   Gravity
2.  Drag   
3.   Thrust
4.   Lift

Paper Plane:

Material:

1. Paper
2.  Scissors

Steps:

1. Fold lengths way
2. Fold it again
3. Fold corners

Findings:

Plane Type	Distance	Behaviour
Normal	5m	straight line
Ailerons	3m	Curves to the side   but straight
Paper clip	5m	straight

Conclusion:

We found that the normal plane flew straight for 5 metres. Secondly, the Ailerons also directed straight but curved a little bit at the end as well and it flew 3 metres. Also with using the paper clip, the paper plane flew 5 metres and it flew straight. Aerodynamics is complex but it can be fun, The word I learnt more about was gravity for example when you walk you have gravity so you can jump around a bit. This project was definitely fun

and I learnt a lot about aerodynamics and the 4 forces of flight.

Home chemistry project 1

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

Materials: 

1. Plastic cup 
2. Water based felt pens.
3. Filter paper
4. Water

Steps:

1. Come and collect your sheet of filter paper.
2. Then we have to measure a line 1 cm from the bottom of the paper.
3. Then make two different coloured dots on the line you drew and wait for the teacher to add a little bit of water.
4. Then see what happens to the felt.

Conclusion:

We found out that the colours mixed together and slowly rose to the top of the paper. We also found out that the blue felt moved faster than the purple as you can see in the picture even though we put the felt in the water at the same time.

Home Chemistry Task

Home chemistry Task!

This term technically we are starting something called home chemistry for our science project. This was our first task.

Aim: To learn the names of 10 household chemicals, their elements, and reactions with other substances.

 

Equipment:

1. Soap

2. Lemon

3. Salt

4. Vinegar

5. Sugar

6. Air Freshener

7. Onion

8. Lemonade

9. Bleach

10. Baking Soda

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

Name	Chemical ingredient(s)	Image	Solid/Liquid/Gas
Salt	Sodium chloride		Solid
lemon	Citric acid		Solid
vinegar	Acetic Acid or ch3cooh		Liquid
Air freshener	Formaldehyde Alpha-pinene		Gas
onion	Potassium, cysteine derivatives		Gas
lemonade	Citric acid, C H O		Liquid
Bleach	Hydrogen peroxide, Sodium hypochlorite		Liquid
Baking soda	NaHCO3 sodium bicarbonate		Solid
Sugar	glucose and fructose, C12H22O11		Solid
Soap	Sodium hydroxide and or potassium,		Solid

In conclusion:

I learned a lot of new things like what everyday house hold objects have in them and if they are a solid/gas/or liquid, I feel like home chem is going to be a very fun project and I am aiming to get a science badge. Hope you enjoyed this.
