What is temperature?
Temperature describes the degree of agitation of the particles of a substance. This means how fast they are moving as well as how many collisions are being made.
What is a hypothesis?
It is a prediction about the lab's result that is made before you conduct the procedure.
The ________________ of the Earth around the Sun and the angle of the Earth's axis is why we have seasons.

How do you test the volume of a regular solid in the shape of a cube?
Measure the length, width and height with a ruler.
Use the formula L x W x H
What is the first phase of the moon following a new moon?
Waxing crescent
Is pure water a good conductor of electricity? In your answer describe the definition of a conductor.
No, pure water is not a good conductor of electricity.
However, many sources of water on Earth have other substances dissolved within them which can make them conductors of electricity.

1. Place the empty weigh tray on the scale.
2. Press "zero" to account for the mass of the tray.
3. Add the powder to the weighing tray.
4. Record the mass.
Why does the South Pole never experience daylight on June 21st?
On June 21st it is one of the two solstices, which is when the Earth is tilted the farthest away from the Sun in one of the hemispheres. In June, the Southern Hemisphere is angled away and the South Pole would never be able to rotate into the area of the Earth experiencing daylight due to the angle of the Earth's rotation and the Earth's location relative to the Sun.

Mr. Twomey is given a beaker of an unknown substance. Describe 3 properties that Mr. Twomey could test for that would help determine the identity of the substance.
You need to test for characteristic properties, which are ones that help you determine the identity of the substance.
Melting Point, Boiling Point, pH, density, electrical conductivity, thermal conductivity would all be good choices.
Mass, volume, temperature, etc. would not tell you the identity of the substance.
How do you determine the volume of a small irregular solid.
1. Fill up a graduated cylinder with water and record the volume.
2. Drop the irregular solid into the graduated cylinder.
3. Record the new volume of the water.
4. Determine the difference between the original volume and the new volume, and record as the volume of the water displaced.
5. Convert between mL and cm3 as the object is a solid, and record the volume.
