Activity! Using the Digital Balance.
Zero a 100 milliliter graduated cylinder. Place 50 milliliters of water in the container and weigh it. How much did it weigh? Place 50 more milliliters in? How much does it weigh? Copyright © 2010 Ryan P. Murphy

Special Relationships
1 cubic meter of water has a mass of one ton, thus… 1 liter of water weighs 1 kilogram. 1 milliliter of water is one cubic centimeter. 1 1 1 Copyright © 2010 Ryan P. Murphy

These are one ton bags of grain.

Metric Ton of Coal

Metric Ton: A cubic meter filled with water or 1,000 kilograms.

Two ways to find the volume of an object
Regularly shaped: use the formula (ex. V=LxWxH) Irregularly shaped: water displacement method The amount of change in the water level is the objects volume; usually in ml Copyright © 2010 Ryan P. Murphy

Density: How much mass is contained in a given volume. We use grams/cm3
(grams per cubic centimeter) Copyright © 2010 Ryan P. Murphy

D = ------------- = grams/cm3 Volume
Density: How much mass is contained in a given volume. We use grams/cm3 (grams per cubic centimeter) Density = Mass divided by volume Mass D = = grams/cm3 Volume Copyright © 2010 Ryan P. Murphy

Which one will sink in water?
Yoshi .75 g/cm3 Donkey Kong. .5 g/cm3 Mario .8 g/cm3 Goomba 1.3 g/cm3

An object will float in water.
Density of less than one = float. Density of more than one = sink. Copyright © 2010 Ryan P. Murphy

New Area of Focus: Temperature.

Temperature: The degree of hotness or coldness of a body or environment.
Corresponds to its molecular activity. Copyright © 2010 Ryan P. Murphy

Which of the pictures below represents hot and cold on a molecular level?

Measured in degrees Celsius.

When it’s hot, the liquid inside the thermometer will expand and rise in the tube.

When it’s hot, the liquid inside the thermometer will expand and rise in the tube.
The opposite happens when it is cold.

Kelvin Scale: Zero Kelvin is absolute zero where molecular motion stops. That is the coldest something can be. (Never been reached.) Water freezes at K; water boils at K. K = C ° Copyright © 2010 Ryan P. Murphy

Molecular motion stops at zero degrees K.

Activity! Red Light, Green Light. Except it’s Zero K, Warm Again.

Activity (Optional) Red Light Green Light

Activity (Optional) Red Light Green Light Zero K Warm Again

Activity (Optional) Red Light Green Light Warm Again Again

Students line up in a safe place. Teacher creates finish line When teachers spins and says Zero K you must freeze / stop. When teacher says Warm Again and spins you may try and advance to the finish.

We won’t use the mole very much in this unit
We won’t use the mole very much in this unit. You will use it later in your science education.

“I’ll be seeing you again, ha, ha, ha.”
We won’t use the mole very much in middle school. You will use it when you take Chemistry in High School. “I’ll be seeing you again, ha, ha, ha.”
