Particle Theory Of Matter:

The Dropping Pins Experiment:

Aim: To Observe Conducting along a metal rod.

Method:

 1. Set up and light a Bunsen burner.

2. smear a small amount of petroleum jelly  on to the head of each drawing pin.

3. Attach the drawing pins at even intervals along the length of the metal rod. 

4. Clamps one end of the metal rod to a retort stand.

5. Position the retort stand so the unclamped end of the metal rod is in the Bunsen burner. 

6. Record the time it takes for each pin to drop in the table below 

These are the results 

Discussion: When we heated one side of the metal it started vibrating along the ling of pins. The Vibrating was coming from the strong particals that are along the line of pins. Which transferred all the way to the end which made all of the pins fall down.

Art

Art: In art we have been learning a whole lot of stuff like under painting and other things. For our drawing we were told to make something with anime and cultural patterns. This is a good idea for our developing artwork because its not basic like a normal eye ball.

The colors I have chosen are great because all my colors are great to blend together. All my colors I have used both blend and look great together. 

First we under painted it with yellow and blue. Yellow is for light colors and Blue is for dark colors. Then we started painting over the blue and yellow and after like 2 or 3 days of concentrating I finished.

English:

English: In English we were told to make a piktochart on 5 things we have learnt in English and the definitions of 8 different words. During the term I have learnt a lot of things like how to identify whats a real statement/story and whats fake. We have also learnt not to believe everything you see/hear on tv. Here ya go :)

My Piktochart

Observing Diffusion:

Observing Diffusion: 

Aim: To observe diffusion in a liquid.

Method:    1. Half fill your petri dish with cold tap water .

2. Place the petri dish on your work bench and allow the water to become settled.

3. Using the tweezers, place a single crystal of potassium in the center of petri dish. 

4. Observe for 5 minutes. 

5. Repeat the experiment using hot water. 

Observation: Basically what we saw was water and die mixed together. It was like if you put food coloring  and water and mixed them.

Conclusion; The Solvent which was hot water/ cold water was put into a container that wasn't that deep. by the way we did cold water first then hot water. Then the solute was put into the water either hot or cold. The solute was crystal of potassium after we put the crystal into the cold water. The crystal would slowly dissolve into a purple die looking stuff but it took so long. Then with the hot water the crystal expanded really quick and took less than 2 minutes. So the solution was basically water and die mixed together. 

Math's: What We Have Been Doing:

In Math's we have been learning about different things we were told to make a blog post of what we have been doing. I'm going to be talking bout two things we have been learning this year. first problem:

 

It’s 5km from Jordan’s whare to where his Koro lives. It’s uphill on the way there so he can only cycle at 10kph but he can do 20kph on the way back.Jordan leaves his whare at 6pm. How long can he stop at his Koro’s whare if he wants to be back home for his favourite TV programme at 7pm?

If he was going 10kph and his Koro lives 5km away then it would take him 30 mins to get there. He will be able to stay there for 15 mins because he will be able to go twice as fast. On the way back and it will take him 15 mins. so it would take him 30 mins to get there 15 mins watching TV 15 mins on the way back which end up being a total of 1 hour.

Second Problem We Have Been Learning: 

Louise just purchased a penny-farthing bicycle. She wants to take it on a 3 kilometre ride.The front wheel on the penny-farthing bicycle has a Diameter of 70 cm. The back wheel on the cycle has a 15 cm diameter. Would the large or the small tyre get more wear and tear on a long journey?

In this one we thought logically because if you think about the smaller wheel will be taking more weight and will be harder than the big wheel. The big wheel is at the front which there's no as much weight then the back and the small wheel on any bike would take more wear in tear depending on what age/weight the best is. Like for example when your young you don't have as much weight compared to a 30 year old. So logically the small tyer will take more wear and tear.

  

Chromatography:

Chromatography:

Aim: To separate the difference pigments in inks using paper chromatography.

Method: 1. cut a piece of filtered paper long enough to reach the bottom of your test tube. 

2. Rule a line in pencil approximately 2 cm from the bottom of your piece of paper. 

3. Fill your beaker with enough chromatography solution to fill your beaker to a depth of 1 cm. 

4. Place a dot of ink above the ruled lone on your filtered paper. You need to produce a concentrated dot of ink so repeated applications mat be necessary. 

5. Suspend the suspend the strip of paper from the pencil stick. You may need to use adhesive tape to stop it from falling into the solution. 

6. Wait to see what happens. It is important that you do not disturb the beaker. If the solution comes in contact with the ink dot, ink will run down into solution, rather than move up the filtered paper. 

Result: 

Discussion:  When we put the solute which was filtered paper with a ink dot in the solvent which was water. It turned the ink drowned down that made a cool design when you left for a few minutes.   

Science:

Aim: To separate a solute from solvent in a solution using evaporation. 

Method:
1. Set up the Bunsen burner, tripod and gauze mat. Don't place the Bunsen burner under the tripod.
2. Add approximately 50 ml of hot water to your beaker and place it on top of the tripod, on the gauze mat.
3. add enough copper sulfate solution to quarter fill the evaporating basin.
4. Carefully place the evaporating basin on top on the beaker.
5. Light your Bunsen burner. Open the air hole and gently push the Bunsen Burner under the tripod.
6. Heat the solution until most of the solvent has been evaporated and crystals of solute forming.
7. Turn of your Bunsen burner.

Results:

Discussion: We evaporated the Solvent which was water. after we boiled the copper sulfate for like 20 minutes then we sat it out for two days after them 2 days we came back and it turned out to a solute. So the solution was blue copper sulfate crystals.
