South Sudan Refugee Inquiry

What you have been learning about?
In Social Studie, we have been learning about Refugees and for assessment, we have been asked to do a Research Inquiry for our chosen country that we want to look at. The country I chose is South Sudan

What you found interesting?
I found interesting how South Sudan is the world's youngest country.

Acid Rain

How is Acid Rain form?

- When fossil fuels like coal, oil, and natural gas are burned, carbon dioxide, nitrogen oxides, and sulfur dioxide are released into the air. These molecules will dissolve in the water in the clouds and make the rainwater more acidic than normal and that is how acid rain forms.

How is it affecting coral reefs?

When the acid rain pours in the ocean/sea and mixed it up with the seawater, the aquatic animals. The acidity threatens the coral reefs by making it hard for the coral reefs to develop their skeletons. 

How can we prevent it?

-Produce energy without using fossil fuels.

- Use recycle material.

- Use renewable resources.

Crystals

Yesterday in science, we have done an experiment.

Aim: To produce copper sulfate salt by reaching the copper oxide with an acid.
Equipment: Copper oxide powder, dilute sulfuric acid, 50mL measuring cylinder, thermometer, spatula, evaporating basin, stirring rod.

How did we make our Crystals?
Method:
1. Add 20 mL of sulfuric acid to a 100 mL beaker Heat the acid until it reaches 70℃. Turn off your Bunsen burner.
2. Heated sulfuric acid.
3. Once heated, use a spatula to add pea-sized portions of copper oxide to the beaker. Stir the mixture for 30 seconds.
4. Repeat step 2 until no more will dissolve. Allow the beaker to cool.
5.. Fold the filter paper and place it in the funnel. Place the filter funnel into the second beaker.
6. Make sure the beaker is cool enough to hold at the top. The contents should still be hot.
7. Gently swirl the contents of the beaker to mix, and then pour into the filter paper in the funnel. Allow filtering through.
8. 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.
9. Place the evaporating basin on top of the beaker and carefully pour some of the solutions from the beaker into the evaporating basin.
10. Gently heat the beaker until the solution in the evaporating basin has reduced by half.
11. Leave the evaporating basin to cool. Once cool, move the evaporating basin to a warm place where it will not be disturbed and observed over the next few days. Blue copper sulfate crystals should form.

What salt are the crystals?

Copper Sulfate.
Chemical reaction: Copper Oxide + Sulfuric Acid ➝ Copper Sulfate + Water

SEXXY Paragraph

For this week in English, Ms Emily Bolt put us into groups of 3. In my group, Lucy is the leader and Sophie is the scribe. In English, we have been focusing on writing a SEXXY Paragraph and we are now analysing low-key lighting from the movie we watched The Power of One. Today, we have only done the Statement.

Making Indicators || Neutalisation

In Science, we have done experiments and we have been learning about base and acid.

Making Indicators

Aim: To make acid-base indicators using everyday substances.

Equipment:

Beetroot, Turmeric, Cranberry juice, Beaker, Water, Tripod, Bunsen Burner, Gauze mat, HCl and NaOH.

Method;

For Beetroot:

1. Chop the beetroot into small pieces until you have enough to fill half of the beaker.

2. Place the beetroot in a beaker and add water to cover the beetroot.

3. Boil over a Bunsen Burner for at least ten minutes for the colours to leach out of the beetroot.

For the Cranberry juice: Pour into a beaker and leave to one side.

For the Turmeric: Mix 1 teaspoon turmeric in 100 mL cup of alcohol. Place in a small beaker and leave to one side.

Task Two:

1. You know have five test tube, each containing a different indicator.

2. Using a pipette, place 5 mL of the beetroot indicator into two test tubes.

3. Add 5 mL of HCl (acid) to one test tube and 5 mL of NaOH (alkali) to the other test tube.

4. Record the colour change on the table below.

5. Clean the test tubes and repeated for the cranberry and turmeric indicators.

Neutralisation

Aim:

To observe a neutralisation

Equipment:

Test Tube

Test Tube rack

Universal Indicator

Sodium Carbonate

Hydrochloric Acid

Method:

1. Add approximately 1-2 mL Sodium Carbonate and place the test tube into the test tube rack. 

Add 3-5 drops of Universal indicator solution.

2. Using a dropper bottle, add HCI(hydrochloric acid) drop by drop. Be careful because adding even a small amount of extra acid can mean you'll miss the neutralisation point.

 

Measurement || Perimeter/Area/Volume

In Math, this past few days we have been learning about "Measurements".

Area;
The area of a shape is a measure of the amount of 2-dimensional surface the shape covers.
Faces; are the flat surfaces of the shape.
Edges; are the lines between faces.
Verticles; are the corners.

Rectangle: 
Area = length x width
Triangle:
Area = 1/2 x base x height
Parallelogram:
Area = base x height
Trapezium:
Area = 1/2 x (a+b) x height

Net
A net of a 3D shape is a plan draw in a 2D that could be cut out and folded up to make that shape.

Perimeter
The perimeter of a 2-dimensional shape is the distance around the outside. Because it is a distance, it is measure in mm, cm, m, or km.

Perimeter = a+a+a+a

Circles
The perimeter of a circle is called the circumference.

If you know the radius: C =2 x π x r
If you know the diameter: C = π x d

- The formula for the area is:
Area = π x radius squared

Calculating Volume
The volume of a 3-dimensional shape is a representation of the amount of space inside it or the amount of 'stuff' that could fit inside the shape.

Cuboid (Volume)
A cuboid is a box shape with all 6 faces being rectangles. This also includes cubes with all faces being square.
The volume of a cuboid is calculated using the rule:
Volume = length x width x height


Prisms
A prism is a shape in which there are at least one directions you would slice the shape, that would create the same cross-sectional area anywhere in the direction. Usually, you need yo calculate the cross-sectional area first.

The volume of a prism is calculated using the rule:
Volume = cross-sectional area x length

Pyramids
A pyramid is a shape that has a particular shape base (often a square) and then all sides face come together to a point. Also, you will usually need to calculate the base area first.

The volume of a pyramid is calculated using the rule:
Volume = 1/3 x base area x height

Spheres
A sphere is a perfectly round solid such as a ball.

The volume of a sphere is calculated using the rule:
Volume = 4/3 x π x radius cube
