Do now week 8.1

 Topic: English is the most important subject to learn in school.

I disagree.

English is not the most important the only time you might use it is when writing an email to your boss however there are some jobs that do rely on English more than other such as being a politician that would require more use but even then not much as most people will have others write speeches for them.

 States of matter

Solid 

Liquid 

Gas 

Plasma

1. What is evaporation

Evaporation is the process of liquid becoming gas due to the speed at which the particles move increasing 

2. What is condensation

Condensation is the process of gas becoming liquid due to the particles moving slower often due to cooling 

3. What is distillation

The separation of a solution using evaporating and condensing 

Aim: To use distillation to separate out the dissolved sugar in coke, coke zero and diet coke

Hypothesis: The liquid will turn into a gas and will leave behind the sugar the one with the most sugar will likely be regular coke 

Equipment:

A solution of saltwater

Conical flask 

Heatproof mat 

A delivery tube and bung

Bunsen burner

Tripod

Gauze mat 

Retort stand

Boss head and clamp 

Boiling tube

Discussion:

The coke zero had less residue than the regular coke and left the flask cleaner in general the residue was the sugar color and additives the water in the test tube was for the most part clear but the regular coke was slightly darker due to there being more color

Chromatography

 1. What is chromatography? A technique for separating mixtures 

 2. What is a pigment? A coloured material that is insoluble in water

Aim: 

To separate the different pigments from ink using chromatography 

Hypothesis: 

The pigments will separate 

Equipment:

Felt tip pen 

Filter paper strips 

Test tube

Measuring cylinder 

Pencil

Method:

1. Draw a line across the filter paper in pencil, 5cm from the bottom 

2. Draw a coloured dot in the centre of the line 

3. Measure 10ml of water and place in the test tube 

4. Place the filter paper in the test tube and fold it over

5. Wait 5mins and observe the results

Do now week 5

 Topic: The principal is the most important person in the school

I agree 

The principal is the most important person because he hires the teachers and plans stuff like mufti days.

Shark infested custard

 What IP skills did you show/use today?

Nonverbal 

How did it help with the success of the team?

I helped pull the person grabbing the end hola hoop which prevented him from falling 

Who did you work with that when well today?

The end person

If you were to do it again, how would you do it differently?

more coordination with the front half

What level of helisons behaviour model were you working at in this activity and provide examples of this

level 3 help others

Marsh mellow tower

What IP skill did you show today and did you say nice things to your team?

The IP skill I used today was verbal communication and I said that my teammates had good ideas 

How did it help with the success/lack of success, of the activity?

It helped my teams succeed because I told them my ideas 

Who did you work with that went well today?

I worked with my teammates  

If you did it again, how would you do it differently?

I would do the strategy that  almost won us the game

What level of Helisons behaviour model did you work at in this activity? provide examples of this 

I worked at level 3 I told my team mates my ideas and I listened to thiers 

Concentration and dilution

Keywords:

Concentration - The amount of constitute divided by the total volume of the mixture

Dilute - A substance weakened by the addition of other substances 

Aim: 

To make a dilute series 

Equipment:

A potassium permanganate 

Six large test tubes 

Tweezers 

A plastic transfer pipette 

A test tube rack 

10ml measuring cylinder 

 Hypothesis: 

The solutions with the least water will appear less and less colourful as more water is added

Method:

1. Place the six test tubes into the test tube rack. label the rack 1-6

2. Using the measuring cylinder fill 1 test tube with 10ml of water and the rest with 5ml 

3. Add a small crystal to the 10ml test tube 

4. Gently shake 10ml test tube until the crystal has been dissolved

5. Transfer 5ml out of the 10ml test tube then repeat until the last test tube

Filtration

Keyword:

Filtration - The separation of different sized particles 

Can all mixtures be filtered - No only insoluble particles can

Aim:

make a mixture and then separate it 

Equipment:

Copper sulphate

Sodium carbonate

stirring rod

200ml beaker

funnel 

filter paper

Conical flask

Hypothesis:

I believe when we try to filter them they will separate due to the particles in 1 chemical having slightly bigger particles but there still may be some residue in the filtered product

Method: 

1. Pour approximately 50mL of copper sulphate solution into a beaker.

2. Add the same volume of sodium carbonate solution. A reaction will happen, you should see a cloudy blue precipitate form. Called copper carbonate. 

3. Watch demo then fold filter paper to fit inside the funnel

4. Place the funnel with the filter paper inside of it, into the mouth of a conical flask. 

5. Stir the mixture in the beaker, then carefully pour it into the funnel. 

6. Observe what happened.

Conclusion: 

When the chemicals were first combined the resulting mixture turned blue and murky then when filtered it turned clear with a light amount of residue and a slightly blue tint

The reaction between the 2 made the copper sulphate into copper carbonate and vies versa with the sodium the copper carbonate turned into the blue sludge that did not filter
