Evidence - Otzi The Iceman

25.05.28


Otzi The Iceman 

In Summary 
In Social Studies we have recently been researching and creating a presentation about a man named Otzi. Otzi was found with his body perfected preserved and still intact because of the cold temperature. This man was discovered by researchers and studied by scientists. We have been learning about Otzi for almost two weeks now and we were given questions to find out. After we finished gathering information we then got into groups and started to build a presentation. My class and I were told to pick a theory based on how he died and provide evidence that can back up our theory. In our research, we found that Otzi was shot with an arrow.  We decided to look more into that and explain how we think he was killed e.g if we thought he was killed without getting a chance to fight back we would have to provide strong evidence to prove so.

Why is Evidence important?
Without having evidence to back up our theory we aren't able to prove or make people believe what we believe, and that's because there is nothing that can persuade them into thinking what we think so to them we could just be telling "lies" or "made up" stories.

Making Hokey pokey

24.05.18

Hokey Pokey

Method
1. Put all ingredients except baking soda in a saucepan over low heat.
2. Raise heat slightly so it bubbles, stirs until sugar dissolves.
3. Take off heat.
4. Add baking soda and stir it. Observe
When we added the baking soda the mixture began to harden.
5. Pour carefully into tinfoil
6. allow cooling.

Equipment

• Saucepan 
• Spoon
• 50g of sugar
• 1/2 tsp baking soda
• 1 TBSP golden syrup.

We formed Carbon dioxide by heating a base which was baking soda which is Sodium bicarbonate and as the hokey pokey began to boil it released/produced carbon dioxide. 
We also added one piece of chocolate to the mixture, and the hokey pokey worked out fine.

SEXXY Paragraphs

24..05.18

This week my teacher had asked us to get in a group with other individuals and create a S.E.X.X.Y. paragraph about one of the camera scenes from The Power of One. 

(S)- The film aspect in this scene has shown a long shot of Sergeant Borman standing directly across
from Geel Piet, who was an African Prisoner.

(E)- In this scene, they used a long shot to show the audience a fair idea of what's going to happen next
as Sergeant Borman stands assertively with his Baton in his left hand facing Geel Piet's direction.

(X)- The director's purpose of using the long shot is to help express the mood and outline the main
problem of the scene, which is Sergeant Borman targeting Geel Piet.

(X)-This made the audience want to get involved in the situation and stand up for Geel Piet. I causes us to be afraid for Geel Piet and feel what he's feeling.

(Y)- This aspect can be compared to when to when the director used a two-shot in the scene when P.K was fighting with an Afrikaner fighter because he may be afraid of what might happen afterwards.

Stone age

18.05.18

Stone age poster:

So this week we have been learning about the Paleolithic and Neolithic people. My class and I were asked to create a post choosing one of those words and researching information about them. As I was creating my poster, I visited heaps of websites making sure my information was accurate. I discovered the way their weapons were made or what they were made out of (e.g They would use rocks and sharpen the tips of the rock to create a weapon.)  I have also learnt that the people of the Paleolithic stone age gathered their food and were only able to take so much. I really liked making the poster because I've discovered things that I didn't even know had happened.

Science Making Indicators

15.05.18

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

Equipment: Red cabbage, tea, beetroot, turmeric, cranberry juice, a beaker, water, tripod, Bunsen burner, gauze mat, 1.0 mol L-1 NaOH.

Method: 

Task one
For the Tea: Put 100 ml of water into a beaker and boil.
Turn off the Bunsen burner and put three tea bags in the beaker.
Remove tea bags when the tea bags when the tea is very strong.
Place in a small beaker and leave to one side.

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.

For the Cabbage: Chop the cabbage into small pieces until you have enough to fill 2 cups.
Place the cabbage in a large beaker and add water to cover the cabbage.
Boil over a Bunsen burner for at least ten minutes for the colour to leach out of the cabbage.
Filter out the plant material to obtain a red-purple-bluish coloured liquid. This liquid is at about pH 7.(The exact colour you get depends on the pH of the water.)
Place in a small beaker and leave to one side.
Repeat this method for the beetroot.

Task two: 
1. You now have five beakers, each containing a different indicator.
2. Using a pipette, place 5 ml of the cabbage indicator into two test tubes.
3. Add 5 ml of HCI (acid) to one test tube and 5 ml of NaOH (Alkali) to the other test tube.
4. Record the colour change in the table below.
5.  Clean the test tubes and repeat for the beetroot, tea, cranberry, and turmeric indicators.

Results:

Indicator	Colour in HCI (Acid)	Colour in NaOH (alkali)
Tea	Orange	Dark violet
Beetroot	Red-orange- peachy	Dirty yellow
Cabbage	Red	Green
Cranberry Juice	Light-rea-pink	Lime-green
Turmeric	Yellow	Red

Testing ph

Aim: To test the PH of a range of household chemicals.

Equipment: a variety household chemical, spotting tile, red litmus paper, blue litmus paper, universal indicator solution, safety glasses.

Method: add a few drops.of each chemical to a spot on your spotting tile. If a substance is solid or powdered you will need to mix it with a few drops of water before testing it.

Test chemicals with litmus papers.

Test each chemical with a few drops of universal indicator.

Results:

Chemical being tested	Colour in blue litmus	Colour in red litmus	Colour in the universal indicator
Pledge Clean & Dust			Red-orange
Morning fresh			green -yellow
water			green-blue
Jif			white-violet
Active fresh			Light blue-orange
Sulfuric Acid			Clear acid-red
Sodium Hydroxide			Clear acid-blue

Conclusion:

Chemical being tested	Acid or base	Evidence from the investigation.
Pledge clean & dust	Acid	Universal indicator
Morning fresh	Acid	Universal indicator
Water	Base	Universal indicator
Jif	base	Universal indicator
Active fresh	acid	Universal indicator
Sulfuric acid	acid	Universal indicator
Sodium Hydroxide	base	Universal indicator

Here are some images of these experiments.

Interviews

Interviews.

Are you addicted to your phone?

*We apologize for the terrible videos or bad quality and we were only able to upload one video due to technical difficulties but please click the links below!*

RESEARCH:

(S)Research shows that young people are often to their devices and other technology. As a group, we interviewed young people to see whether or not people are addicted their devices.

(E)During the videos, each individual talks about how much time they spend on their devices and answered a whole bunch of questions. We wanted to get different perspectives from different genders and ages. (E) Out of the 5 videos only one of the students admitted to being addicted and was very honest about how often they spend time on their device and how it affected the way they communicated with other individuals such as their family or friends. This individual, in particular, was the youngest between the four. (L) So we came to a small conclusion that maybe the younger you are the small your attention is drawn to small or big devices such as phones, computers, or consoles. Another interesting thing we learnt is that some kids were given their first device at a very young age, we want to know what you think about it and what you think the right age to give a child a device is.

In some of these videos, we have chosen not to film the people, because of some of the student's would not like to be filmed. You are still able to listen to the questions and answers.
