Hurumanu 3 - Chaos - Black death

 Hello everyone, this chemical and chaos we are learning about The Black death, but right now we are learning about Fleas and rats. We are asked to make a Basic paragraph about the subject of black death, we have to get a topic about it. Here is the paragraph I made about it.

Basic Body Paragraph. 

Fleas and Rats. The fleas and rats were the problems to have the pandemic about the black death, it

causes a lot of problems around the city that had been hit by the black death. The black death started in

China and pass it through the ships trading routes westward to the Mediterranean. It then reached Rome,

the centre of an elaborate web of trading routes, Florence, Paris, Bordeaux, Lyon and London.

The fleas were very dangerous at that time because the fleas pass the bacteria from the rat to a human. Rats

were a pest and they would always eat human foods. Rats would always eat something they think it’s edible.

Rats go to places that they shouldn’t and that’s how the fleas go to rats and fleas would jump to another rat

or person to get rid of the blood and get another blood from someone or something.

Timeline

Hello everyone, this Hurumanu 3 we have been working on a timeline about the black death. We have to make the timeline and pick what or when was the chaos. There's no much information about it and it's more like the time and pictures.  Here is the timeline I made. 

Evaporation Experiment

Hello everyone today we are doing evaporation while doing the experiment we are looking at the changes in the water and also see the evaporating basin. The experiment was fun because we used bunsen burner, I had to lit a fire by a lighter. The water was condensing, steaming, boiling and evaporating. At the bottom are the aim, hypothesis and the equipment used. 

Separating a Mixture using Evaporation:

Aim: why you are doing the experiment

To separate a solution into a solvent and solute using evaporation.

Hypothesis: what you think will happen, and why….

I think it will heat up and the copper sulfate will leave some crystal at the sides.

Equipment: Copper sulfate solution, 250mL Beaker, heatproof mat, evaporating basin, element. 

Method: 

1. Set up element

2. Add 100mL of hot water to the beaker and place on the element.

3. Add copper sulfate to the evaporating basin until it is quarter full.

4. Carefully, place the evaporating basin on top of the beaker. 

5. Turn on the element to 3

6. Heat the solution until most of the solvent has been evaporated and crystals of solute are forming. 

7. Turn off the element- be careful not to touch, as it will be hot for a long time.

Observations: What did you see, hear etc when doing the experiment.

The boiling was loud so you could hear the boil of the water and also you can hear the gas.

Conclusion: Was your hypothesis correct?

yes, the crystal stayed and it has some a little bit of kinda glitter.

Discussion: What happened and why… using your scientific keywords (Evaporating, Solvent, solute, solution, mixture, heat, boil) The water started boiling because of the heat and while it was boiling the steam started coming out of the beaker. When it

Evaluation: Did you enjoy the experiment? Why? What would you do differently next time? 

I enjoyed it because I'm learning something new and I had fun with my group but some people in our group sometimes don't really do anything so I would like to change it.

Copper sulfate is poisonous

-Evaporating

Here are the pictures that we took.

Dilution

Hello everybody, this chemistry we are experimenting with Serial Dilution. The picture below is the aim and the instruction about our experiment.

• Which was most dilute?  least concentrated 

The most dilute one is the last on because it has been passed and passed until the end and makes it weaker or dilutes more.

• How do you know it's more Dilute and Concentrated? Explain?

I know this because of how transparent or less colour they have meant that it's more diluted. The stronger the colour is mean its more concentrated 

Here are the pictures that we took.

Esol - Halloween Project

 Hello everyone, this week we are working on our presentation about the scary myth about our own culture. I had a lot of fun making the short film because my teammates Janel and Shiela made it fun while filming. It was a bit stressful to edit because I don't really know what I would put fo the caption. If we had more time editing it, I would make some changes to the voice-over because it didn't really explain about the lady in white. Here is the video I made with my teammates and I hope you like it.

So if you don't really understand the story I will just explain it to you. The story is mainly about the lady in white, the lady in white usually seen at night and in the morning. The lady in white usually is seen if they need your help or there is something about you that they hate or they are part of your family. You can find a lady in white in rural places or tragedies places. That is all the information I have about The lady in white I hope you like the video and have a nice day.

    

Bag making - Textiles

 Hello everyone, this textile we have been working on the bag we are making. I haven't started sewing my bag yet but sooner I will, I only have cut the stakeholder one bag and I'm still working on what would stakeholder would have. 

Stakeholder 2 should have looked like this, but we don't have any materials that are pink and blue.

Stakeholder 1 should look like this and I don't have to change anything, I just have to sew it and put the details on it.

     

Gymnastics - P.E

Hello everyone, this P.E we are doing gymnastics, We learnt how to cartwheel, bear roll, the beam and the trampoline. We take photos of us doing the activities in gymnastics. We got better doing the trampoline and at the mat where you do front roll cartwheel and stuff. I have to practise more on the beam because I'm a bit scared of hight. Here are the pictures and videos we took.

Filtration Experiment

Hello everyone, Today we are doing a filter experiment. We have a filter paper to filter the chemical we are experimenting, and no we can't drink it because we don't know if it's clean. At first, we have to put the blue transparent liquid and the name is copper sulfate. We add the transparent chemical which is sodium carbonate. when we stirred it looks like a blue opaque liquid.

 Aim: To Separate a solution from a precipitate (precipitate is the name for a solid that forms in a liquid during a chemical reaction).

Hypothesis: what do you think will happen...

I think that the dirty things to the chemical will stay at the filter paper and the bottom will be clear.

Method: 

1. Pour approximately 50mL of copper sulfate 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.

Observations and Discussion: what you saw happen and why do you think it happened...

The liquid turns to transparent and there are some left blue thing left at the top of the filter paper. 

Equipment:

Sodium carbonate

Copper sulfate

Conical flask

Stirring Rod

200mL Beaker

Funnel

Filter paper
