1 Did you know... Kids ask questions about Light and Sound

2 How many different tones does sound have? * When you are singing the same note, you can change the volume,so the wave will change. Higher waves are louder, close together waves have a higher pitch. High pitch instruments ranking 1st. Piano 2nd. Glockenspiel 3rd. Piccolo 4th. Harp 5th. Violin 6th. Flute 7th. Clarinet 8th. Oboe 9th. Viola Low pitch instruments Ranking 1st. Tinpani 2nd. Contra Bazoon 3rd. Saxophone 4th. Double Bass 5th. Tuba 6th. Tronbone 7th. Bazoon 8th. Heckelphone 9th. Horn 10th. English Horn Did you know that the faster the waves wobble, the higher sound it will be. So the slower the waves wobble, the lower sound it will be. 10th. Trumpet

3 How many kinds of light are there? There is many kinds of light and there is Gamma ray light:the light that lots of energy travel right through us like human or animal X-Ray:Enough energy to travel through considerable thickness of material. Only some material can stop it infrared light:this light of heat visible light:light that human and most animal can see, has all of the colors in it white light: the light that bends the light and separates white light into different color. ultraviolet light: sunlight contains UV rays small amount of UV good nout large cause skin cancer &bad eyes microwaves:shorter than the radio waves radio waves:are use for electronic such as TV, Radio Did you know that the animal like bird turtle or fish can see the world with so different color with what we are looking.

4 Why isn't sound warm or cold? Feelings Sound makes you feel things. When you hear the sound your brain says something and you have a feeling. Energy Sound waves produces the heat, but not so much. When sound travels the particle move but, not very fast. Warm - nature, smooth, soft, Tuba, Cello, Oboe, Timpani, Double Bass Cold - metal, straight, hard, Violines, Hieknote, Flute, piccolo, Triangle, Glockenspiel, fingers on a blackboard Did you know... An orchestra can heat a cup of coffee, if you wait a while

5 How do light bulbs work? Humphry Davy (1778~1829) was the inventor who invented light bulbs for the first time. 60 years after Humphry Davy's death, Thomas Edison, came out with a great idea to make the light bulb stronger. There is no air in a light bulb, because if there was air, the wire will burn away. If you put in the argon gas, the wire will be very hot and produces light. If you connect the screw thread to a battery, the electricity from it, goes up through the wires and to the filament, and that's how light bulb can glow. Did you know you may think Thomas Edison was the inventor of light bulbs, but Humphry Davy was the real inventor who invented it. Electricity is based on the light of a light bulb. bulb glass Atoms are tiny collections of electricity, which we call protons, neutrons and electrons leg support wire Humphry Davy's first light bulb *filament glass bead screw thread cap Filament is the important part, because electricity goes through the wire(filament), the filament gets hot and makes it glow

6 Why can't we hear sound without air? Sound cannot travel without air, also we can't hear sound without air and ears. Did you know...if you cover your ears, you will almost hear nothing because the air won't go through to your ears!

7 Can Sound go through Walls? Sounds can go through vibration and dry walls. Walls that Did you know that in space there's no sounds. The most important thing on Earth is air. But sound waves can also go through solid materials. Sound Waves Water Sounds are shapeless like water, it doesn't have a form but molds itself to the thing it is in. Sounds passes on energy from one molecule to another molecule in any materials. Sound does travel faster in solids than in liquids, also faster in liquids than in air. We can hear through solids, but not very well. It doesn't have anything to do with the speed of the sound in the material.

8 What is the difference between light waves and sound waves? Sound If you make a high sound, the waves are close together Sound waves are invisible if you make a low sound, the waves are far away Sound is a type of waves, like a ripple in a pond Similarities They both are waves. light and sound bounces off and something can stop them. Differences Light When something blocks the light it makes a shadow We need light to live We need light to see for example coal there are visible light waves but there isn't visible sound waves. They can go through something. sound vibrates to make us hear, light bounces off and needs color to see Did you know If you take a paper and put a magnifyin g glass and the sun will make the make a hole the the paper and it will have Sound waves light waves

9 Why do bugs like light? Bugs like light. Why I'll tell you! (in an easy way) Introduction; So, First of all bugs need light. Why? They need to navigate where they're going by light. Bugs uses light to navigate where they're going so sometimes bugs bump into light which is moon, stars, and Light Bulb. What happens next? They burn. 1) Safety Bugs think Light are safe so, they Fly into the Light. 2) Navigation Bugs uses light to navigate They will know where to go. Did you know...but not all bugs are attracted to light, for example Cockroaches and earthworms are afraid of light. This is an Bug Zapper. Is attracts bugs. The Bug Zapper has Blue light so bugs go near the light, And BUZZ gone. By Meu

10 What can stop sound and what can sound go through? Sound uses air to move around, so to stop sound, you need walls that don't have any holes. To stop a wall from vibrating, it needs a lot of mass. Air has a little mass, so it vibrates easily letting sound travel through it but all the mass in the air grows more so if someone is shouting in the distance, the sound has to pass lots of mass in the way so it gets quieter and quieter. Did you know... The first soundproof room was built in the 1970's! Roxul insulation Wall mechanism

11 How can some animals hear sound better than humans? Elephants can hear better than humans because their large ears have large hearing canals Bats ears are super sensitive Bats, dolphins, and whales are some of the animals that use echolocation. The animals that use it are the best hearing creatures A sound wave's height is determined by the volume. The louder the volume, the higher the wave. The lower the volume, the lower the wave If the periods are close together, then it is a high frequency wave and/or has high sound. If the periods are far apart, then it is a low frequency wave and/or has low sound. Bugs Humans Animals that use Echolocation Dogs Did you know... Low What Animals can Hear What Frequency High A dog whistle seems to make no noise, but really, since dogs hear a much higher frequency than us, it is making a really high noise,but we can't hear it!

12 How does sound travel under water? The sound travels in the waves. Sound wave travels through air and solids (Metal pipes that can carry sound waves in long distances. Also peoples voice travels through the air. The sound in underwater travels faster than the sound in the air. Solid is very hard firm object that takes space. Sound is vibration. Sound travels in through water like when they travel in air. Sound travels in mechanical waves. (Mechanical waves mean are disturbance that moves and transports energy from the one place to another place through the medium.) In sound disturbance is a vibration object. Medium can be any series of interconnected and interactive particles That means sound can travel through gasses and liquids and also solids. Sound can go through water even when you say "Hi!". Underwater you are producing air bubbles that make sound. Whales Communicating Whales There are many types of whales. For example, Killer whales, Beluga whales, etc. Killer whales clicks to talk. Beluga whales hum and communicate. Whales talk in low voices. But Beluga whales have high voices. Did you know that when whales howl the sound waves go across the sea 10,000 kilometers.
