Model 3D

This is what i do for my project, which is 3D model, and i decided to do topic solid geometry.
Although you may think that it was easy to do that but it actually need a lot of effort and time! You can try to do it on your own, what you have to prepare is only A4 paper, sciscor, glue, ruler and also pensel. See, the material is all very easy to gain and it really worthy to have a try on it!
I feel really satisfied after doing all this, have a feeling like back to secondary school sumemore xD
Now, have a look on what i have done^^

All of the 3D model that i have done^^

This is pyramid, i feel most satisfy with this!

This is cone, this one quite hard to do because of the round surface area below is hard to attach to the upper surface of the cone.

This is rectangle

This one is cylinder, and is the model that i take the longest time to finsh it!

This is cube, small cube, have a big one some more

This is triangular prism, a bit looks like a pyramid

And this is the big cube! i want to keep all my 3D model inside this big cube ^^

 Hope you enjoy with what i have done ;)

Form 1 Chapter 7 >>> Heat

This is the last topic for Form 1 Science syllabus, hope you all enjoy all the content i post here ^^

Heat is the amount of energy contained in a substance. Its SI unit is Joule (J).

Temperature is the measurement of the degree of hotness or coldness of a particular object. Temperature can be measured by a thermometer and is measured in degree Celcius.

Heat and Temperature

Conduction is the process of heat tranfer from a hot area to cold area throughout a solid.

Different solid conduct heat at different rates.

Substances which allow heat to flow quickly are called conductors while allow heat to flow slowly are called insulators.

Electrical Conductor

Electrical Insulator

Convection is the process of heat transfer in fluids as a result of the movement of the fluid from a hot area to a cooler area.

Radiation is the process of transfer of heat from a heat source to the surrounding without the presence of any medium.

Conduction, Convection, and Radiation

Medium is a transmitting substance which allows heat to be transferred. For example, particles of solids and liquids.

The principle of heat transfer in everyday life can be through using kitchen utensils for cooking, air-conditioners, electric kettle, refrigerators and others.

The principle of heat transfer in nature can be seen in sea breezes, land breezes and the warming of the Earth by the Sun.

Sea Breeze

Land Breeza

Opaque and dull surfaces absorb and radiate heat more effectively than shiny surfaces.

Book Cover

This is first time i design a book cover for my project work! Initially i thought it was easy but absolutely it was not! I keep design and design and i get one quite satisfy and after i print out, it was a wrong thing totaly from my design because i was using a wrong landscape.
However, luckily i able to finish my book cover design before presentation and i hope other also will feel it like a real book cover as i really put a lots of effort and time especially in design! Hope that others will like it too! haha^^

This is the front page of my book cover ^^

And this is the back cover of the book 

hehe finally it look like this! xDD

This was really a good experience to me, now i am very proud to say i had already success to design a book cover haha! xDD

Form 1 Chapter 6 >>> Sources of Energy

Here is some important part in Chapter 6, students can have a review here^^
6.1   The Various Form and Sources of Energy

- Energy is defined as the ability to do work. Energy is measured in joules (j).

- Energy can be found in many forms :

a) Kinetic Energy

• Kinetic energy is the energy possessed by a moving object.
• The kinetuc energy of an object depends on ots mass and velocity.

example of kinetic energy-running of leopard

b) Potential Energy

• Potential energy is the energy stored in a body due to its position (gravitational potential energy) or its physical condition (elastic potential energy).
• The gravitational potential energy of an object depends on : the mass of the object, the distance of the object from the Earth's surface, and the power of the gravitational pull on the object.
• A falling object gain kinetic energy but loses potential energy.
• Elastic potential energy exists in only elastic substances such as spring or a rubber.

elastic potential energy

c) Heat Energy

• Heat energy is the energy that is stored in hot object.
• The heat energy of a body depends on its temperature and volume.

Heat Energy

d) Light Energy

• Light energy is the energy produced by an object that emits light.
• Light energy can travel in a vacuum and in a straight line in the form of waves.

example of light energy

e) Sound Energy

• Sound energy is the energy produced by a vibrating object.
• The vibrating air forms sound waves.

example of sound energy-drum

f) Chemical energy

• Chemical energy is the energy stored in a chemical substance.
• When substance undergoes chemical reaction, chemical energy which is stored will be released and converted into other form of energy.

example of electrical energy-battery

g) Electrical Energy

• Electrical energy is the energy produced by the flow of electric charges

example of electrical energy

h) Nuclear Energy

• Nuclear energy is the energy stored in the nucleus of an atom.
• Also known as atomic energy.

example of neclear energy-nuclear plant

i) Mechanical Energy

• Mechanical energy is produced when a machine or object change its position.

example of mechanical energy-used in meter glass

j) Solar Energy

• Solar energy is produced during the process of nuclear fusion in the Sun's core.
• Almost all the energy currently available comes from the Sun.

Solar energy comes from Sun

Sources of Energy
Types of energy source on Earth

• Fossil fuels
• Biomass fuel
• Radioactive substance
• Mechanical sources
• Geothermal sources
• Sun

6.2   Renewable and Non-Renewable Energy Source

• Renewable energy source of energy are energy sources which can be used again because the supplies are not limited. Example : wind, solar, hydro, wave, biomass, etc.
• Non-renewable energy sources of energy are sources of energy which are limited in supply and will be used up in a short period of time. Example : fossil fuels and radioactive souurces.

Form 1 Chapter 5 >>> The Air Around Us.

Air is made up of a mixture of nitrogen (78%), oxygen (21%), carbon dioxide (0.01%), inert gas (0.97%), water vapour, dust and microorganisms

Composition of Air

Properties of oxygen : - slighty soluble in water ; not soluble in sodium hydroxide ; relights glowing splinter ; has no effect on moist litmus papers.

Oxygen relights glowing splinter

Properties of carbon dioxide : Slighty soluble in water ; Very soluble in sodiem hyroxide ; lime water turns cloudy ; change moist blue litmus paper to red.

Carbon dioxide turns lime water cloudy

The content of oxygen in exhaled air is lower than inhaled air. Human beings breathe through the respiratory system.

The respiratory system involves the process of oxidation of food in living cells.

During respiration, oxygen is absorbed into the cells, while carbon dioxide will enter the alveolus to be excreted.

Combustion takes place when a substance combines with oxygen chemically to release heat and light energy.

Combustion of carbon produces carbon dioxide, light and heat energy. Combustion of hydrocarbon produces carbon dioxide, water, heat and light energy.

Green plants carry out photosynthesis to manufacture food.

Photosynthesis

Air pollution occurs when the air is made dirty by air pollutants such as smoke, dust, carbon monoxide, sulphur dioxide, nitogen dioxide, and residues of pesticides.

The causes of air pollution include motor vehicles, factories, burning of rubbish, and widespread use of pesticides.

Air pollution can cause acid rain, increase in Earth's temperature (greenhouse effect) and thining of the ozone layer, and affect the health of organisms.

Form 1 Chapter 3 >>> Matter

In this chapter, the most important thing is you should know what is 'matter' .

3.1   What is matter

• Everything, whether living or non-living things, which has mass and occupied space is called matter.

3.2   The States of Matter

3.2.1   Kinetic Theory of Matter

• According to kinetic theory of matter, matter is made up of tiny particles which are discrete (seperate)
• These particles can be composed of atoms or molecules
• Atom is the smallest particle of matter and cannot be further divided. Molecule is made up of two or more atom.

3.2.2   Arrangement of Particles in Matter  (Solid, Liquid, Gas)

• Solids consist of particles that are arranged close together and in a regular pattern. The particles are not free to move and can only vibrate about their fixed positions. A solid has definite volume and shape.
• Liquids consist of particles that are arranged fairly close together but not in a regular pattern. The particles can move freely (flow) and vibrate. A liquid has definite volume, but its shape change depending of its shape of container.
• Gases consist of particles that are far apart and not in a regular pattern. The particles are free to move in all directions. A gas has neither a definite volume or shape.

For more information, try to click at this link : Arrangement of Particles in Matter .

3.3   The Concept of Density

• 
  The density of an object is the mass per unit volume of the object. The SI unit is kg/m^3.
• An object that is less dense will float on a liquid that is denser. An object which is denser will sink in a liquid that is less dense.

Chapter 2 >>> Cell as a Unit of life

Below are summary of Form 1 Chapter 2 :

• Cell is a basic unit of living things.
• Each cell can function and survive on its own. Cells can perform life processes such as digestion, respiration, excretion, reproduction, growth, and response to stimuli.
• Animal cell do not have definite  shapes because there are no cell wall. The cell do not have chloroplasts to help manufacture food. The number of vacuoles in animal cells is very small and sometimes none at all.  
• Plant cell have definite shape because the cell walls are made up of cellulose. The cell can also manufacture their own food because the chloroplasts have chlorophyll. The vacuoles of plant cell are big and fill with cell sap.

Plant cell

Animal Cell

• Unicellular organisms are  organisms made up of one cell only (single cell). Examples : Amoeba, Euglena and  yeast.



Euglena

Amoeba

• Multicellular organisms are organsms with many cells. Multicellular organisms are more complex than unicellular organisms. Examples : Hydra, Spirogyra, human beings.



Human Being

Spirogyra





• Both unicellular and multicellular organisms can perform similar life process.
• Organisation of cell in the human body involves the following stages:

                    Cell =>> Tissue =>> Organ =>> System =>> Organism
