All light is bright and so are these ten facts!
- Light comes in two forms of energy, brightness and heat. Light also has two groups, natural light, like stars and fires, and artificial lights, like electric bulbs and lamps.
- The sun’s light travels 299,260 km/186,000 miles per second which means it takes 8 minutes to reach Earth.
- A shadow forms when a ray of light shines on a solid object.
- Transparent materials allow light to travel through it, while translucent materials let a little light through. Opaque materials let no light through.
- When a ray of light touches a shiny or polished surface, the ray bounces back.
- When light travels through a fine droplet of water or a prism, a rainbow forms.
- Light rays contain colour. These colours are red, orange, yellow, green, blue, indigo and violet. Light’s primary colours are red, green and blue (RGB).
- Each wavelength of light is smaller than your hair.
- The longest wavelength, red, has the least energy while the shortest wavelength, violet, has the most energy.
- Light rays bounce off colours of its same colour type, while other light rays are absorbed when they touch a colour that is not its same colour type.

This black resource found in the Earth is very interesting so I’ve got 10 facts about crude oil.
- Crude oil seeps to the surface of the Earth and gathers in pits.
- Crude oil is naturally formed by squeezing and heating up the remains of animals and tiny sea creatures into a liquid.
- Crude oil is usually only found where there are layers of sedimentary rocks since these rocks have been formed like crude oil.
- To collect the crude oil, an oil driller would use a large drill to dig oil wells.
- Upon the collection of the crude oil, it is necessary to take all the water and oxygen out of it.
- Crude oil is stored in a tank with a bobbing lid, to stop any gases that could damage or even make the crude oil explode upon contact.
- To make crude oil usable, you must make it float better, make the oil burn better, make it not dangerous and remove the bad smell.
- The Middle East contains the most crude oil in the world.
- Crude oil can be found at sea so floating cranes are needed at deep areas.
- Crude oil contains carbon and hydrogen, hydrocarbon.

Tornadoes are very destructive winds that cause heaps of damage! Here are ten more facts about tornadoes.
- About 1,200 tornadoes are seen every year in the USA.
- The winds at the bottom of a tornado spins faster than the winds at the top.
- Tornadoes have never been spotted in Antarctica.
- Tornadoes form when a downdraft of moist and cool air mixes with an updraft of warm air.
- An average tornado only travels a few miles before it dies out.
- The wind speed inside a tornado is about 110 mph/117 km (per hour).
- A tornado’s colour changes, depending where you view it or what the tornado sucks up. This means a tornado could be white, red, blue, brown, grey, orange, yellow and even invisible.
- Tornadoes may not always be visible. If a tornado is visible, the tornado would have low air pressure produced by high wind speeds that mixes the humid air into clouds.
- Tornadoes are most common in Spring and least common in Winter. This is because Spring produces stronger winds while Winter produces the weakest.
- There are many types of tornadoes including waterspouts, dust devils, snow devils, fire wheels and the typical cyclone.
