Rohingya Research Assessment

In social studies, we're learning about refugees. We've been asked to create a presentation and choose a country we want to research on for our assessment.

Crystals, Acid Rain

PART 1: Crystals

How did we make our crystals?
1. Add 20 mL of sulphuric acid to a 100 mL beaker. Heat the acid until it reaches 70 degrees celcius. Turn off your bunsen burner.
2. Once heated, use a spatula to add pea-sized portions of 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 funner 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 filter paper in the funnel. Allow to filter 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 solution 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 disturb and observe over the next few days. Blue copper sulphate crystals should form.

What salt are the crystals? - copper sulphate salt

PART 2: Acid Rain

How is acid rain formed?
- When fossil fuels such as coal, oil and natural gas are burned, carbon dioxide, nitrogen oxide and sulphur dioxide escape into the air. These molecules dissolve in the water in the clouds and make the rainwater more acidic than normal. When this happens, it is called acid rain.

How is affecting coral reefs?
- when the acid rain pour down, the water in the ocean is now mixed with the acidic water affecting living things there.

How can we prevent it?
- don't burn fossil fuels or things like that.

SEXXY Chart

In English, we're learning about film techniques. We worked this chart as a group and I'm working with Logan and Austin. I learned how to write a SEXXY paragraph. The thing that I could do better next time is that put more detailed in my sentences or paragraph.  

Statement	Evidence	Explanation of Director’s purpose	Explanation of effect on audience	Your link (to wider world, rest of film, self)
Facial expression of Geel Piet	Geel Piet is getting beaten by the sergeant	To show how the two feels	Audience feel scared for Geel Piet	It links when Geel Piet is eating poop

Maths

This week in maths, we learned how to get the volume of a cuboid. A cuboid is a box shape, with all 6 faces being rectangles. This also includes cubes, with all faces being square.

Volume of a cuboid = length x width x height (whatever the measurement is, you have to add small 3 after the measurement)

Music Performance Reflection

1. What instrument did you choose to learn and why - piano because I can play it
2. What song did you choose to learn and why? - twinkle twinkle little star because we don't have time left
3. What was challenging about this piece and how did you overcome the challenges? - playing it together, we practice together
4. Were you happy with your final recording/performance? why? yes because we finished it in time
5. What would you change about your performance if you could do it again? - i would play it with my left hand
6. Were you happy with your overall grade and why? - yes because achieved is better than not achieved
7. What have you enjoyed about Music this semester? - playing piano
