Biological molecules

A molecule is any particle composed of two or more atoms held together by forces known as chemical bonds. There are four major classes of biological molecules: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are the most abundant molecule in living organisms and are essential for cell structure and function. Lipids are non-polar molecules that include fats, oils, waxes, and steroids. Fats contain long chains of carbon atoms with fatty acids at one end. They form structures such as cell walls and insulation to protect against extreme temperatures. Proteins are amino acid chains that make up about half of all protein molecules and have many important functions such as enzymes, hemoglobin, antibodies, hormones, etc. Nucleic acids (DNA) store genetic information in the form of genes arranged linearly on a double helix strand which can be separated into individual components called nucleotides (or bases).

Cell structure and function

All cells are enclosed by a plasma membrane, which separates the cell from its surroundings. The cell membrane is a selectively permeable barrier, meaning that it allows some substances to enter and exit the cell while keeping others out. As such, this organelle maintains homeostasis in the cell’s environment. It is also responsible for allowing nutrients into the cell (a process called endocytosis) and sending waste material out of the cell (exocytosis).





Gases are more likely to be found at the earth’s surface than in the atmosphere. Gas is any substance that is lighter than air, has no color or smell, and usually has a fluid form. Oxygen, nitrogen, carbon dioxide, water vapor, and hydrogen are all gases. The composition of these gases changes with temperature and pressure. For example, oxygen is a gas at room temperature but becomes liquid when it is cooled below -183 degrees Celsius. One of the most common uses for gas is as fuel. Natural gas, coal gas, and propane are examples of fuels that release energy from their chemical bonds when they react with oxygen. Fossil fuels like oil and natural gas have been used for many years because they can be burned to create heat and light.


Liquids are the easiest to transport. The water cycle can be explained with these. Methane gas is the main component of natural gas, while petroleum (crude oil) is a fossil fuel. Oxygen is required for life and carbon dioxide is released during respiration and decay. The water cycle describes the process of how water on Earth circulates as liquid, vapor, and ice according to the temperature/humidity conditions in the atmosphere.

Water is the most abundant liquid on Earth. Every living thing needs water to survive. Up to 60% of the human body is made up of water. Not only is water essential for life, but it also has many other uses. For example, water is used for cleaning, transportation, and recreation.



Solids are substances that are unable to flow or change shape. A perfect example of a solid is ice, which does not melt when it gets warm and does not turn into a liquid. Another example of a solid is coal, which will not dissolve in water or evaporate like gases. These two solids show that they have the same property: they are both things with a definite shape and volume.

Chemical Equilibrium

Chemical Equilibrium is the state of equal concentrations of molecules on both sides of a reaction. For example, consider a hypothetical reaction between hydrochloric acid and table salt. Chlorine gas is released in the reaction, which can be harmful to the environment. Hydrochloric acid reacts with sodium chloride, forming sodium hydroxide and hydrogen chloride gas.




Rotational Motion

There are various types of rotational motion, but all have the same basic underlying principles. In a rotating system, each point has an angular velocity relative to the center of rotation. The speed of rotation is measured in revolutions per minute (rpm). If the object is not uniform, then there will be a net torque on the object which will cause it to accelerate. The acceleration is given by the equation a=rω2, where r is the radius of rotation and ω is the angular velocity.

Circular Motion

One of the basic principles of physics is that an object in motion will continue in motion unless acted upon by an outside force. This is known as the law of inertia. Inertia is the resistance of any physical object to any change in its state of motion; this includes changes in its speed, direction, or shape. For an object to change its state of action, a force must be applied.
