Rocks
The uses of rock
What is counter tops, buildings, tools, monuments, and pottery?
I left some water sitting in the sun for 3 hours. If I put a thermometer in it, and had you guess the temperature, what question would you want to ask before guessing the correct temperature of my water?
40o F or 75o F
Did you have ice in the water?
If yes- 45o
If no- 75o
The tool used to measure temperature.
What is a thermometer.
A scientist who studies rocks and minerals to learn more about the history of Earth.
What is geologist?
Rocks are made up of _____ or more minerals.
What are two?
I am a geologist. I often study the texture of rocks. What questions to I ask about the rocks to figure out the texture?
Is it rough or smooth?
Heat is a property of minerals.
True or False
False
An object that allows heat to pass through it very easily.
Conductor
(Metals are conductors)
Material found in nature that may be made up of one or more minerals, clay, sand or fossils.
What is rock?
The type of rocks all over our playground.
What is granite?
I am counting how many colors and crystal formations I see in my rock. Why am I doing this?
To see how many minerals are in your rock.
I put on a fluffy jacket in the winter time.
Explain the heat source and how the heat is moving in this situation.
My body is the heat source.
The heat moves from my body through the jacket, to the cold outside. The jacket slows down the escape of the heat though.
Styrofoam is an example of this because it slows down the movement of heat.
An insulator
The softest mineral.
What is talc?
Stone Mountain is this type of rock?
What is granite?
If I scratch the mineral with this item, I know it must be really soft like talc.
My fingernail.
Which was does heat mostly move?
A. From Warm.....to.....Cold objects
B. From Cold.....to .......Warm objects.
A. Always from Warm object ......to cold object
or from Warm place to a cold place.
What 2 questions would you ask me if I told you I had found some good materials for keeping the inside of a dog house cool in the Georgia hot summer?
A Variety of questions are possible but here are some examples:
Are the materials insulators? Is it wood? Is it white?Does it have Styrofoam? Does it slow down the movement of heat energy?
I have a 10 rating on the Moh's scale, I reflect light, I am shiny, I have a smooth surface, I mostly have a CLEAR color.
What mineral am I?????
Diamond
If I want to find out a mineral's luster I would ask this.
Is it shiny or dull?
A tool used to get a close up look at rocks and minerals during class experiments.
What is a hand lense, or magnifying glass?
I put my hot soup in two different cups. It started at 400 Celsius. The soup in cup A was 32o degrees Celsius after 30 minutes. The soup in cup B was 38o Celsius after 30 minutes. I now know that the material used to make cup B was a good______. (Answer Why for extra points.)
Insulator
Because it kept the soup warm. the temperature only dropped by 2 degrees.

Insulator
Because if it had been a good insulator the temperature of the soup would not have dropped so much. (From 40o-32o)
I am a 1 on the Moh's scale.
I am usually white.
You can scratch me with your fingernail.
What mineral could I be?
Talc
This mineral is about a 1.5 on the Moh's Hardness Scale and you use it every day in school.
What is graphite?
