What is the difference between weather and climate?
Weather happens a particular time and place. Changes day-to-day.
Climate is the average weather conditions of a particular region.
What tools would you use for mass, relative density, magnetism, and temperature?
Mass: Scale
Relative density: Beaker of water

A solution is a special kind of mixture where one substance dissolves evenly into another. Cannot be easily separated.
A mixture is two or more different things that are physically combined. Can be easily separated.
Explain the different forces.
Gravity: A force that attracts two objects to each other.
Magnetism: A force that pulls Metals toward a magnet.
Friction: A force that slows or stops motion when objects rub together.
Push: A force to move something AWAY.
Pull: A force to move something TOWARD YOU.
In most of the United States, including Texas, how does the length of daytime change from winter to spring?
A. Daylight will decrease from the winter months through the spring months.
B. Daylight will increase from the winter months through the spring months.
C. Daylight remains the same from the winter months through the spring months.
D. Daylight will increase and decrease slightly from the winter months through the spring months.
B. Daylight will increase from the winter months through the spring months.
Evaporation, Condensation, Precipitation.
Evaporation: When water changes from a liquid to a gas by the suns heat.
Condensation: When water vapor changes from a gas to a liquid as it cools (forms clouds).
Precipitation: Water that falls to earth (Rain, snow, sleet, hail).
Which set of items is most likely magnetic?

B. paperclip, toothpick
C. crayon, penny, toothpick
D. metal spoon, paperclip
D. Metal spoon, Paperclip
Which statement is true about the wood pieces in the soil?
A. The wood pieces are more dense than water. Therefore, the wood pieces float on top of the water.
B. The wood pieces are less dense than water. Therefore, the wood pieces float on top of the water.
C. The water is the same density as the wood pieces. Therefore, the wood pieces float on top of the water.
D. The water is less dense than wood pieces. Therefore, the wood pieces float on top of the water.
B. The wood pieces are less dense than water. Therefore, the wood pieces float on top of the water.
Is it easier to slide on ice or carpet? Why?
Friction is a force that slows things down when two surfaces rub against each other.
- Ice is very smooth, so it has low friction. That means there’s not much resistance, so you can slide easily.
- Carpet is rough, so it has high friction. It “grips” your feet or objects more, making it harder to slide.
Why does the moon appear to change during the month?
A. Because the clouds in the sky hide the moon from Earth.
B. Because the sun blocks the moon from Earth.
C. Because the moon moves farther away from Earth.
D. Because the moon reflects sunlight as it rotates around Earth.
D. Because the moon reflects sunlight as it rotates around Earth.
Which sentence desribes climate? Select two.
A. It rained 5 millimeters last night in New York.
B. A jacket is usually needed in January.
C. The wind is blowing at 10 mph from the north.
D. Florida has very long, warm summers.
E. It is cold and rainy this morning in Houston, Texas.
B. A jacket is usually needed in January.
D. Florida has very long, warm summers.
Explain each physical property.
State of matter: Solid, liquid and gas
Relative density: More density (Sink) or Less density (float)
Temperature: Hot or cold something is.
Magnetism: If something is attracted to a magnet.
Mass: Total amount of matter in an object.
