What are the three states of matter, then say what they are called for water.
Gas, liquid, and solid
Water vapor, water, and ice

Two factors that can weaken a magnet's pull is barriers and distance. Describe those factors with two examples.
A barrier is something between the magnet and iron, like paper.
Distance is how far away the magnet is from the metal object it is trying to attract.

Water is made of tiny particles. For each state of matter, they move at a different speed.
For the three states of matter, list how fast the particles are moving from the slowest to the fastest.
Solid- the particles are very close together; they are still moving, but stay in the same spot.
Water- farther apart than a solid; move around more and slide over each other
Gas- very far apart and move quickly in all directions.

If I went to Mars, which would change: my WEIGHT or MASS
My weight would change because it is how much I weight compared to the gravitational pull.
My mass does not change.

Use the 7 physical properties used to describe a kiwi you are about to eat.
Hardness, color, size, taste, texture, odor, shape.
The student will describe a kiwi

Where does this magnet attract the MOST amount of metal, and where does it attract the LEAST amount of metal?
The ends of the poles are going to have the strongest magnetic field, and it grows weaker as it goes toward the middle.

When heat is added to water or a liquid, the particles speed up. Once they speed up enough, it becomes WATER VAPOR. What is this process called when liquid become gas?
Evaporation happens, and the water vapor goes up into the clouds.

Density is the amount of ________ in a certain ________ of a substance.
Mass, volume

How can I measure the volume of an orange by placing it in a beaker with water in it?
You record how much water is in the beaker BEFORE the orange- then when you place the orange in the water, you record the new volume of the water with the orange.

How can a scientist make a piece of metal into an electromagnet?
By connecting it to a battery and running electricity through it with wires.

Let's say you are walking with a friend and it begins to rain. He turns to you and says,
"Look- evaporation is happening because the gas has turned to liquid, which falls down from the clouds in the form of rain."
How is he wrong?
It is not evaporation, but condensation

I have a rubix cube that is 4 inches high, 4 inches long, and 4 inches wide.
Find the volume of the rubix cube.
height x length x width = volume
4 x 4 x 4 = 64 cubic inches

You are hiking in the woods and pull out your compass. The compass needle points to North- why does this happen?
This happens because the needle is attracted to the magnetic pole near the Earth's geographic North Pole.

Starting with freezing, describe the change of state for water as it goes through the four states.
1. Freezing- water freezes into ice
2. Melting- ice melts into water
3. Evaporation- water becomes water vapor
4. Condensation- water vapor becomes condensation (rain, snow, sleet)

You are a scientist studying two different rocks.
One rock has particles that are not tightly packed together. The second rock is very firm and its particles are very close together.
Which is more dense?
The second rock!
