Properties of sound.

Hello world this is my properties of the sound unit,

I hope you enjoy it!

Properties of Sound I

In class, we cut a small hole in two cups And stuck a string in the hole. Then we had One person on one And another on the other side. But….. it didn’t work!

Properties of Sound II

We did another experiment, which was… putting our ears to our desks and where hitting them with our fists and it was cool I Guess. But wait that’s Not it! There is more we also did it with other things all the way from a door to ollies head!

(notes his head sounded hollow)

Properties of Sound III

Now for the coolest one…

We used sound tuners and did super fun things! first, we hit our desks at the same time then we hit whatever we want!

After that the teacher wanted us to settle down and then told us to stop then she gave us a cup of water and we hit our desks with the tuner and dipped it in the cup and…

It like made a big splash.

Properties of Sound IV

This is the second coolest one so we used the cup from before then added some foil over the top, then put sand and hit our desks, and then… the sand exploded kind of maybe like uh…..

now for the last one we got papers of an ear then we put clay and wrote in a box what part of the ear the clay is in!

I hope you enjoyed It so… Yeah………….

Wait… oh yeah

Artificial sources of light versus natural sources

We/my class sorted out manmade sources of light versus natural sources.

down here is manmade sorces of light, and below it, is natural.

Artificial sources of light: glowsticks, fireworks, lightbulbs, candles, oil lamp.

Natural sources of light: fireflies sunlight glow worms.

 

 

 

Objects that emit light, Objects that reflect light

This time we sorted out objects that emit light and one that reflect light.

These are the ones we sorted.!

Light emitters: HDTV, candle, sunlight, moon, star.

Light reflectors: table, water bottle, bowling shoes.

also here a random fact luminous means something that emits light and non-luminous means a random object that doesn’t

Experiment 1:   In the first experiment we lined up cards with holes in the middle except for one in the back because that

one had a target on it but we shined a flashlight at the cards and hoped it hit it, and sure enough it went through!

 

 

 

 

Experiment 2:What makes a good reflector?

I did an experiment about reflecting a flashlight at different things such as glass, tinfoil, crumpled tinfoil, black paper,

white paper, and green paper.

the best reflector was crumpled tinfoil and the worst was

black paper.
