Social Studies - Stone Age Art

29, Thursday, August 2019

In Social Studies we have been doing about Stone Age and today we were told to paint on the walls about Stone Age. Here are some pictures for our classes Stone Age Art...
And Videos

In these photos, you can see that our class are painting and most of them used paintbrush, sticks, and hands you cannot really see but most of them used each stuff to paint.

Explain why and how they made art??

Early they used materials like stone, ivory, and bone. They made paints from natural pigments using iron oxide to create scenes of animals on walls deep in caves.

Where is the Stone Age Artwork found??
It is usually found in Caves a lot.

The art that I was doing was about people hunting for a Deer together.

Home Economics - Making Pizza

In our last lesson in Home Economics, we made Pizza Dough or just Pizza.

Ingredients :

* 1 cup of self-rising flour ( or 1 cup of plain flour and 1 teaspoon of baking powder)
* 1 cup of unsweetened yogurt
* 1/2 tsp salt

Method:

1. In a bowl combine all ingredients
2. Bring them together to form a ball.
3. Turn out onto a floured board. Knead and roll the dough for 5-8mins
4. Break into even parts for each person in your group.
5. Roll into an oblong or round shape.

To make homemade pizza:

1. Pre-heat oven to 200 degrees Celsius.
2. Spread tomato onto the pizza base.
3. Add your favorite topping eg. cheese, tomato, Blah blah blah.
4. Bake for 10mins or until cooked.

Science - Circuit Board Of An Comupter!

Circuit Board... What do we know about Circuit Board??

Hmm... It's a closed path through which sn electric flows or may flow. A Power source that is connected to two or more components eg. light bulbs, or computer circuits They are called a series of circuits.

Printed Circuit Board (PCB) Build - Up

PCBs are made of multiple layers of Core, Prepreg,  and Copper Foil.

Core:

There are 2 types of Core. 

One is things made out of metal on the Circuit Board or PCB.

  

Second is Core that is used in PCB, underneath the Core they have whole bunch of threads that receives instructions and performs the calculation.

Prepreg:

Prepreg is a Carbon Fiber that is used to stick the core layers together.

How does Circuit Works Or PCB??

In our bodies, our heart produces the pressure to make the blood circulate, a generator or battery produces the pressure or force to push electrons around the circuit board. In our body Walls of blood vessels impede the flow and the smaller the blood vessel, the more resistance to flow. Some of the pressure produced by our heart is just for pushing blood through the blood vessel. As electrons move through wires, they bump into atoms. This impedes the flow of the electrons, the wires offer resistances to the flow of the current. 

Electric circuits are composed of wires and other components like bulbs, transistors, computer chips, and motors. Wires are made out of metals called conductors that have a low resistance to current. A Chip is a tiny piece of silicon, usually around one centimeter squared. A chip may be a single transistor ( Its a piece of silicon that amplifies electrical signals or serves as an on/off switch in computer applications). 

The most important elements in an electronic circuit are the transistors. Diodes are the tiny chip of silicons that act as valves to allow current flow in only one direction. The other electronic components are passive elements like resistors and capacitors. 

Resistors look like this...

The resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. It can be used to provide a specific voltage for an active device such as transistors.

And Capacitors look like this...

Capacitors are used in charge pump circuits as the energy storage element. Capacitors are connected in parallel with the DC ( Direct Current) power circuits.

The third passive circuit element is the inductor, which stores energy in the form of a magnetic field.
An inductor/ coil or reactor is a passive two-terminal electrical component which resists changes in charges in electric current passing through it. It consists of a conductor such as wire, usually wound into a coil. The Energy is stored in a magnetic field in the coil as long as current flows. 

This Picture here...

All components are through-hole mounted, they are placed on top of the board, their electrical connections ( the legs) pushed through holes in the PCB, and then soldered from the bottom of the board. There are two thicknesses of track the thin tracks used for signals requiring little current flow, and the thicker tracks are used for the component power supply a positive or negative that requires a great current flow.

Social Studies - Graph

In Social Studies, 10Hh started to share with our class about how long do you stay on your device. We had to download an app and it records the amount of time you've used.
Here is the graph about the longest Device used...

This is the Graph about People used there devices for the longest. Sadly I this graph doesn't allow me to add which people used there device for long but you can see how long they've used the highest is 43 Hours and the lowest is 30min.

This next graph is about what type of devices they used most...

This is what amount of people from 10Hh used most of there devices.

School Uniforms - English Essay Writing

Should schools get rid of uniforms??

How would you feel when school will get rid of school?

I think schools shouldn’t get rid of uniforms Because, if the schools get rid of school uniforms the students will get bullied in school. They’ll compare how expensive clothes they’re wearing and also the school rating will go down. If students won’t wear uniform’s this might cause a lot of Bullying, Self-conscious and terrified.

In school students get bullied for different kinds of reason’s and there is a lot of reason. If schools got rid of uniform’s these takes to a reason that students get bullied, how?, well first of all they compare their clothes to each other for example, I'm wearing the most expensive and branded shoes, and the other student is wearing a cheap pair of shoe so they get picked up by rich students. But not only shoes they also compare their accessories, etc.

Students get Self-conscious (Embarrassed) every single time, now you're wanting to know how do students get embarrassed by wearing clothes. Well first thing, talking about school uniforms students don’t get embarrassed if all of them are wearing the same uniforms but when it comes to mufti or schools got rid of uniforms students get self-conscious because they don’t know what to wear or not or even though they go to school in their mufti clothes they’ll be shy, they’ll be confused pretty much.

In school students try to look cool, stunning other sorts of stuff, but their friends or other students don’t know what's the secret behind him or her for being cool. Student’s wearing cool clothes makes them look cool but their friends won’t know how expensive or cheap are the clothes, so when students wear cool clothes to make them self look cool but they are terrified because most of them don’t want to let their friends or other students around them know that it’s a cheap type of clothes and if that happened they’ll get bullied and getting exposed in front of students.

Another thing about not wearing school uniforms is that people and students from outside can get in school easily because they'll be wearing random clothes and not school uniforms. This can cause a lot of problems in schools. So should we keep uniforms or not??
