Hello there i want to tell you about an experiment that i did about minerals rocks and the earth. I took a cookie one hard and one soft and used toothpicks to dig into the cookie and take out the chocolate chips. Sort of like the chocolate chips were a diamond and i was a geologist.

 

What is a geologist?

A geologist is a person who studies minerals rocks and the earth. A geologist takes chunks of a wall or cave and studies the rocks they took to see if they are valuable or not. or a new type.

 

What types of rock are there.

There are 3 types of rock. sedimentary metamorphic and igneous. Sedimentary is a soft rock that eventually hardens into a rock. Sedimentary is made up of many small rocks. Metamorphic is a rock that is below the ground and is made from earth’s heat which gets formed from the pressure and heat. Igneous rocks are made from a volcano made lava and it hardened which made a rock. if the lava hardens with air bubbles and that makes holes in the rock. There are 2 types of igneous rocks.

I want to tell you about my sound unit I’m learning. Sound is a travelling wave which is an oscillation of pressure transmitted through a solid or liquid or gas composed of frequencies within the range of a level of sufficiently strong to be heard or the sensation stimulated in organs of hearing by such vibrations.

Can you tell me a fact about sound and the speed of it.

Fact Sound travels a lot slower than light if it’s in air or water. light travels 186,000 miles a second while sound travels at 770 miles an hour.

What are the properties of sound? and how sound travels.

sound is an energy we can hear. sound is associated with vibrations. when something vibrates it moves back and forth quickly. properties of sound. Property.1 sound can be reflected meaning it CAN bounce off things. Property.2 sound can be absorbed meaning it does NOT bounce off things. Property.3 The sound can be modified meaning the pitch and loudness is changed. Property.4 sound is caused by vibrations.

What is a pitch?

A pitch is how high or low a sound can be. a firework would make a high pitch sound, a low pitch sound could be a big drum. A pitch is measured in hertz one hertz means that one sound wave will hit your ear every second. Humans could hear from 20 to 20000 hertz.
