  • His biological parents went on to have another child, Mona Simpson, whom he later met and connected with.
  • Jobs were a pescetarian which meant he ate fish but no other meat.
  • At the tender age of 12, Jobs asked William Hewlett, co-founder of Hewlett-Packard for some parts to complete a school project. Hewlett offered Jobs an internship at his company.
  • Jobs met Apple co-founder Steve Wozniak in high school when Jobs was 13 and Wozniak was 18.
  • His Full Name is Steven Paul Jobs.
  • When he returned to Apple in the mid 90s, Steve Jobs donated Apple’s first computers, machines, blueprints to Stanford University.
  • His Religion is Zen Buddhism. He went to India to meditate and learn about a simpler way of life.
  • He was very private about his marriage. His wife was Laurene Powell Jobs and they got married in Yosemite national park on March 18, 1991.
  • His wife is an MBA graduate of Stanford and was appointed by President Obama to be a member of the White House Council for Community Solutions due to her active involvement in the non-profit community.
  • Despite his wife’s work in the non-profit sector, Jobs was not known for his charitable works.
  • Apple had three founders, not two. The company was founded in 1976 by Steve Jobs, Steve Wozniak and Ronald Wayne.
  • The first Apple logo was drawn by Ronald Wayne who also wrote the original partnership agreement and the Apple I computer manual. Unfortunately, he sold his 10% stake two weeks into the partnership for just $800.
  • Steve Wozniak ended his full-time employment in 1987. However, he is still an official Apple employee and receives a stipend estimated to be worth $120,000 a year.
  • Jobs believed Google had stolen some of the features of the iPhone and decided to keep the development of the iPad a secret from Schmidt.
  • Do you know facts about Steve Jobs that Apple I was the company’s first computer and was priced at $666.66.

Laws of Motion

Laws of Motion
A force is anything that can change the state of motion of an object, like a push or a pull. Forces are everywhere. Gravity acts as a constant force on your body, keeping you secure on planet Earth so you don’t float away.

Laws of Motion

A scientist named Isaac Newton came up with three Laws of Motion to describe how things move scientifically. He also described how gravity works, which is an important force that affects everything.

Must Read: Laws of Physics and Chemistry

First Law of Motion

The first law says that any object in motion will continue to move in the same direction and speed unless forces act on it. That means if you kick a ball it will fly forever unless some sort of forces acts on it! As strange as this may sound, it’s true. When you kick a ball, forces start to act on it immediately. These include resistance or friction from the air and gravity. Gravity pulls the ball down to the ground and the air resistance slows it down.

Second Law of Motion

The second law states that the greater the mass of an object, the more force it will take to accelerate the object. There is even an equation that says Force = mass x acceleration or F=ma.

This also means that the harder you kick a ball the farther it will go. This seems kind of obvious to us, but having an equation to figure out the math and science is very helpful to scientists.

Third Law of Motion

The third law states that for every action, there is an equal and opposite reaction. This means that there are always two forces that are the same. In the example where you kicked the ball, there is the force of your foot on the ball, but there is also the same amount of force that the ball puts on your foot. This force is in the exact opposite direction.

Fun facts about Forces and Laws of Motion

  • It is said that Isaac Newton got the idea for gravity when an apple fell off a tree and hit him on the head.
  • Forces are measured in Newtons. This is after Isaac Newton, not fig newtons, even if they are tasty.
  • Gases and liquids push out in equal forces in all directions. This is called Pascal’s Law because it was discovered by the scientist Blaise Pascal.
  • When you go upside down in a roller coaster loop-the-loop, a special kind of force called “centripetal force” keeps you in your seat and from falling out.

Oxygen Cycle

Oxygenis an important element to life on Earth. It is the most common element of the human body. It makes up about 65% of the mass of the human body. Most of this is in the form of water (H2O). Oxygen also makes up about 30% of the Earth and 20% of the atmosphere.

The Oxygen Cycle

Oxygen is constantly being used and created by different processes on planet Earth. All of these processes together make up the oxygen cycle. The oxygen cycle is interconnected with the carbon cycle.

Plants are the main creators of oxygen in the atmosphere through the process of photosynthesis. Here the tree
uses sunlight and carbon dioxide to produce energy and releases oxygen. The giraffe breathes in the oxygen and then breathes out carbon dioxide. The plant can then use this carbon dioxide and the cycle is complete.

Also Read : Water Cycle

Processes That Use Oxygen

  • Breathing – The scientific name for breathing is respiration. All animals and plants use up oxygen when they breathe. They breathe in oxygen and breathe out carbon dioxide.
  • Decomposing – When plants and animals die, they decompose. This process uses up oxygen and releases
    carbon dioxide.
  • Rusting – This is also called oxidation. When things rust they use up oxygen.
  • Combustion – There are three things needed for fire: oxygen, fuel, and heat. Without oxygen, you can’t have a fire. When things burn, they use up oxygen and replace it with carbon dioxide.

Have a Look at: Erosion

Processes That Produce Oxygen

  • Plants – Plants create the majority of the oxygen we breathe through a process called photosynthesis. In this process, plants use carbon dioxide, sunlight, and water to create energy. In the process, they also create oxygen which they release into the air.
  • Sunlight – Some oxygen is produced when sunlight reacts with water vapor in the atmosphere.

Fun Fact About Oxygen Cycle

  • Even though fish breathe under water they still breathe oxygen. Their gills extract the oxygen from the
    water.
  • There is a lot of oxygen stored up in the oxide minerals of the Earth’s crust. However, this oxygen isn’t
    available for us to breathe.
  • One of the biggest sources of oxygen is phytoplankton that lives near the surface of the ocean. Phytoplankton is tiny little plants but there are lots of them.
