making salt

making salt

Aim: To produce copper sulfate salt by reacting copper oxide with an acid.
Equipment: Copper oxide powder, dilute (0.5 mol L-1) sulfuric acid, 50mL measuring cylinder, two 100 mL beakers, Bunsen burner, tripod, gauze mat, funnel, filter paper, thermometer, spatula, evaporating basin, stirring rod.
Method: 

1. Add 20mL of sulfuric acid to a 100mL beaker. Heat the acid until it reaches degrees. Turn off your bunsen burner.
2. Once heated, use a spatula to add pea-size portions od copper oxide to the beaker. Stir the mixture for 30 seconds.
3. Repeat step 2 until no more will dissolve. Allow the beaker to cool.
4. Fold the filter paper and place it in the funnel. Place the filter funnel into the second beaker.
5. Make sure the beaker is cool enough to hold at the top. The contents should still be hot. You may need your teacher to complete this step.
6. Gently swirl the contents of the beaker to mix, and then pour into the filtered paper in the funnel. Allow filtering through.
7. Rinse the beaker you used to heat the mixture previously, and place it back on top of your tripod filled with 50-60 mL of water.
8.  Place the evaporating basin on top of the beaker and carefully pour some of the solutions from the beaker into the evaporating basin.
9. Gently heat the beaker until the solution in the evaporating basin has reduced by half.
10. Leave the evaporating basin to cool. Once cool, move the evaporating basin to a warm place where it will not be disturbed (i.e. a window-still) and observe over the next few days. Blue copper sulfate crystals should form.

Discussion:

This was a fun experiment to do and when doing it I saw the copper oxide dissolve so many times and we had to like 3-5 pea-size full of the copper oxide. We then had to wait for it to get to 70 degrees when waiting we were a bit worried because we didn't want it to explode and crake the glass because it was getting really hot, and last time we did this experiment it happened to a few people in our class. In my group, I was the one that had to fold the filter paper and we weren't told how to do it and I knew that there was a certain way to fold it so it would actually work. So I had to guess, I ended up getting it and we were all ready to go. During the experiment, the reaction that was happening was copper oxide+ sulfuric acid ---> copper sulfate+water
 (CuO + H2So4--->CuSo4+H2O).
When we had finished the experiment we were waiting for it to cool down but someone in our class decided to touch it and tried to move it (Don't do that) when they went to move it they spilt it and it went on them and on the floor, they had to wash it off and our experiment was ruined and it didn't work. The next day we went to go and do it again but there was no more solution left and we couldn't do it. So I just took photos of other peoples experiments and how there's went and how it was meant to look.   

Evaluation: 

If you do this I would recommend making sure your measurements are accurate and correct. I would also say wait for the beaker to cool down before touching it so you don't spill anything. If I was to do it again I would make sure no one touches it when it is hot and I would make sure I get good photos so they are more clear and it isn't all foggy and blurry.  

Kulture

In art we have been learning how to create magazine page layouts and how we can incorporate what we have learnt over the last term into out pages. Over he past few week we were learning how to create leading lines and focal points into our work and how to make it all fit in with each other. At the start of this we had to create some layouts of what we wanted out page to look like or what we sort of wanted it to look like and then we had to go on to Adobe Illustrator and have a turn on that and create a page on that.

Our page that we done is nothing like the way we wanted it so we are going to change the whole thing. 

When we restart we are going to add some of our own art work instead of just having stuff off the internet.

When my dad Steve died my mum Emilia was left alone in England with a 10-year-old girl and a business that wasn't going so well and wasn't making enough money to support us. Mum and I decided that it was best for us and the business to move away from England and our home to start a new life somewhere else. Something you should know about my family is that we would always move around England because my dad was in the army, this would sometimes make my mum angry and whenever she got angry she would take it out on me, I didn't like it but I couldn't do much about it. The most memorable memory I remember about my dad was that when we would go to the park and walk around he would yell out to me saying “ Emma come back here” because I would always run off from them and be ahead. So when mum said we were moving I didn't want to move because it was brought back a lot of memories of dad, but I didn't say anything because it would have just made her angry and I didn't want to do that because we had just lost my dad. So when we started looking for a place to move to mum didn't want somewhere in England and that is when we ended up finding a small country called New Zealand around 18 thousand km away from England. When my mum and I found this country we knew it would be a good place for us to move to and a good place to start over again because it will be easier for us financially and there is more land there. Finding this country made me not as sad to move because it looks like a nice place. Before we left mum sold the business and all the jewellery that was in it to. The guy that brought it was some rich buyer so we had enough money to support us for a bit and enough money to get our tickets to New Zealand. When mum sold the business we went out and brought our tickets. Mum brought herself a cabin ticket and me a steerage ticket so we saved on money. The day of our departure we had to wait for about 30- 50 mins for our boat to get to the docks, then when it finally arrived at the docks we ended up having to wait another hour to actually be allowed onto the boat. While we were waiting for the boat and all that, we went for a walk to all dads favourite places he would go to when he wasn't working. We went to the park where dad and mum met each other, for the last time. We walked back to the dock and boarded our boat this is where mum and I went our separate ways because we were in different seats.

On our journey to New Zealand, mum was seated in the cabin part of the boat and I was seated in the steerage by myself with others that were in there too. Sitting in there made me really wish I was in the cabin part with mum because it stunk and it was way too cramped for the number of people that were in there. When I would get bored I would either play chess or cards sometimes I would wonder what mum was doing whilst I was stuck down here, but I knew that if she had enough money she would have got me a cabin seat to. A lot of the journey the weather would play up and keep changing making the boat feel really ruff and bring out the bad smell of the dead animals and livestock. When it was time to eat I was served dried potatoes, salted and preserved meat, floured biscuits and oatmeal, whilst mum was probably served freshly cooked meat by the crew.  Not to mention the only way I could wash was by using the salt water from the sea and that was on the good days sometimes I didn't even get to wash. This is what my life was like for the next 50-60 days. And during the ride, there were a lot of sick people that were in the steerage, and to go on top of having a lot of sick people around me I think I might have caught something from another kid. The rest of the way to New Zealand I felt a bit sick but I didn't know if it was from getting sick or from the sea and the weather being so ruff. When we were near to the dock I was taken up to my mum and we waited for the crew to tell us we had arrived at the dock and were ready to get off. Before we got off my mum asked me "do u feel okay" I think it was because I looked sick so I just replied with " yeah I feel fine" and after that, we were on our way off the boat.

When we first stepped off the boat I remember thinking wow this place look so nice, because when our boat arrived at the dock I couldn't see anything since I was down in the steerage which is why I had to wait to see what it was like. Before my mum and I were allowed to step foot onto New Zealand land we had to show someone our tickets so they knew we really did pay for our tickets and that we didn't sneak onto the boat. Once all that was done and sorted with we walked over to get all our stuff like our clothes and some personal belongings, I still felt a bit sick but I didn't say anything because I thought it was just seasickness and it will pass by soon. While we waited for a ride into the town I ran around and played so I could stretch my legs since I was stuck in that cramped place for 50- 60 days on the boat. Our ride arrived in about 5-10 mins, it arrived and we hopped in, While we were on our way to the town the driver was telling my mum and I a little bit about New Zealand, and how the Maoris were the first people to ever stet foot onto New Zealand. As we arrived in the town I looked around and I was so surprised at how different it was compared to England. We hopped off our seats and out of the vehicle to walk around the town and find where we were staying. As we walked around I felt a bit sick still and I ended up passing out. I woke up in what looked like a hospital and the last thing I could remember was hitting the ground. When I sat up I found that my head was hurting and I saw my mum sitting next to me on a chair waiting for me to wake up. One of the doctors came in not too long after that and told my mum that I was very sick and wasn't looking so good. When I found out the news I wasn't really sure how to react because we had not long just lost my dad and now my mum is going to lose me to all in the same year. Laying in the hospital bed made me feel more tired, but that also could have just been because I was dying and getting sicker the more I sat in that bed. A few days went by before I died and left my mum. In those few days, I couldn't really do anything because I was too tired to move. One day my mum decided she was going to go home and come back the next day so she could get a few of my things and some games to play, like cards and chess. When she arrived back at the hospital the next day she was too late and I had passed away overnight in my sleep. When I was dying I didn't know what was going to happen to my mum, like if she was going to be a slave, housemaid or something else, and that really worried me.

burning magnesium

Burning magnesium 

Aim: to see the change in the weight of the magnesium.

Equipment: 

scales

bunsen burner 

scissor tongs 

beaker

lighter/ matches

heatproof mat

safety glasses 

Safety:

• Have your hair tied up if it is long.
• Wear safety glasses. 
• Don't go to close to the flame.
• If you forget to put on safety glasses don't look at the light of the magnesium burning.  

Method:

1. Collect your equipment and set up your heatproof mat under your bunsen burner, do not light the bunsen.
2. Once set up with all your stuff cut and put your magnesium inside the medium size beaker and weigh on your scales. (Take note of the weight.) 
3. Once you have set up and you already turn your bunsen onto safety flame, then light your bunsen burner and turn it to the blue flame. 
4. When done that take your magnesium out of your beaker and hold it with the scissor tongs.
5. You then want to hold the magnesium over the middle of the flame and wait for it to catch fire.
6. When your magnesium has caught fire you want to then put it into the beaker and wait for it to go out and turn to ash.
7. You may need to repeat this a few times.
8. When all or most of the magnesium is ash and it is inside the beaker you then want to weigh it again and compare the different weights.

Observation:

Discussion:

When I was doing this I found that you had to be very precise and careful when you weighed your magnesium because if you did it wrong or something was different then when it came to doing it again and getting the results at the end it wasn't correct. We also found out that if you don't burn all/ most the magnesium or don't get as much of the magnesium off the tongs then you will end up with the wrong results. At the start of our expement, we were using paper instead of the beakers but we found that when you put the magnesium ash onto the paper it caught fire so we decided to use the beakers instead. When doing this the magnesium is meant to get heavier than the first time you weighed it, but ours ended up getting lighter because we didn't burn all of it and we lost some of it when it got stuck to the tongs. My group started at 53.49 and we ended up with 53.39 so ours got lighter.

In therey, it should have gotten heavier.

Evaluation:

If I was to do this again then I would want to make sure I burn all the magnesium and get a more accurate result to what it should be. If you were wanting to try this then I think you need to pay close attention to the magnesium and make sure you burn most of it. I would also say that you might want to do a little bit of research on this just so you have a little bit of an idea on what you are meant to be finding out and what is actually going on when you are doing this.  

 

Grilled beef kofta

What will I do next time:
Next time I think I will soak the wooden skewers longer and make the meat longer and thinner.
What I learnt:
When making this I learnt that you should add more flavouring to your meat so that it isn't as bland.
Teamwork:
Whilst making this I thought our team worked really well together and all helped out and done our jobs.

Zootopia

Introduction:

A character who changed in Zootopia was Judy. Judy changed because at the start of the movie she thought that zootopia was the perfect place and she has a lot of confidence, during the film Judy starts to lose that confidence and stops believing in herself, towards and at the end of the film Judy gets her confidence back.

Body 1

Judy begun as a confident bunny that believes in herself and knows what she wants. We know this because at the start of the film when it is the play scene, where the children were saying what their dream jobs were. When it came to Judy’s turn we see her move toward the centre of the stage and closer to the audience. We can also hear her say “my dream job is to be a police officer”. Once Judy has said this one of the audience members (Gideon Gray) stands up and laughs at her. In response to this Judy replies back by talking about Zootopia and how perfect it is and how it is a place where anyone can be anything.

Body 2

Judy in the middle of the film was starting to lose her confidence and stopped believing in herself.

This is because of when Judy had to talk to the reporters she doesn't know what to say and just starts talking about how all the animals affected were all predators. When Judy was getting asked too many question mayor Bellwether had to come on stage and take Judy off. Once Judy was finished she walked over to Nick and she could tell that he wasn't too impressed with what she was saying. Nick ends up walking out of the building making Judy sad and making her realize what she has done. When she realized what she did wrong she goes and talks with the chief and mayor Bellwether. They want her to be the face of the ZPD, but she doesn't want to because she thinks she isn't a hero. In this scene, we can see that Judy is sad not only from her tone in voice but in the way her ears are drooping down. We can hear Judy say “ I came here to make the world a better place, but I think I broke it” she is saying this because of how the press-conference went and how what she said during it changed the perspective of so many animals and not in a good way now the animals that are considered predators are being feared from the animals that are considered good and safe. I think that in this moment she loses her confidence because of what has happened and what she has done/said.

Body 3

Judy at the end of the film started to get her confidence back and started to believe in herself. This is because in the scene where Judy’s parent are working with Gideon Gray she first was a bit thrown back but when he starts to apologize she understood and saw that he had changed. We see Stu hopps (Judy’s dad) tell the kids not to go near the Midnicampum flowers. We can also hear Gideon Gray say “ Well now there’s a $4 word you mr.H my family always just call them night howlers”. In this scene we see Judy’s ears going up which makes the audience think that she has an idea, When Judy starts to put all the clues together she figures out what was happening to the animals going savage. I think that in this moment she gets her confidence back and starts to believe in herself again.

Conclusion

Throughout the film, Judy went through stages of believing in herself and then not. At the start of the film, she was confident in herself, in the middle of the film Judy loses all her confidence and stops believing in herself, but towards the end, she gets it all back and believes in herself. I think the directors did this to make a point that even when you go through bad times you can always turn things around. That is why they also would have used some certain lines in the film and some certain film shots to make the film or scene more realistic and relatable.

Sonia Terk Delauney

Orphism art: Orphism is a type of abstract art form that uses bright colours.  

2 facts about Sonia Terk Delauney: 

1. Sonia Terk Delauney could speak 4 languages at the time she was 18. The languages she could speak were Russian, German, French and English.
2. when her husband Robert Delaunay died in 1941 she stopped making art for 10 years. She started to come back into the art around 1950.

Our learning outcome has been: To look at Sonia Terk Delauney and Orphism to develop an understanding about who and what this is. We have been doing this through linocut printmaking. We have also looked at the focal point and leading lines.

Our techniques have been: Drawing Terk Delauneys work and understand the context. We have had to do some thumbnail sketches with colour and annotation. Then we have to turn them into lino designs.

Evidence of this:
