Anita had a nail, a pencil, a rubber eraser, a paper clip, and a plastic ruler. She tied a piece of string around each object and used tape to suspend each one from the edge of a table so it could swing freely. Then she brought a horseshoe magnet slowly toward each object and observed what happened. She wrote her observations down and started weighing each object. What question did Anita want to answer with her experiment?
What types of materials are attracted to magnets?
Why does a magnet attract certain materials but not others?
Does an object's mass affect whether it is attracted to a magnet?
How can a magnet's strength be increased or decreased?
Which of the following methods is BEST for separating a mixture composed of pieces of sawdust and sand?
using filter paper.
stirring the mixture with a spoon.
removing each substance by hand.
pouring the mixture in a water filled container.
Which containers are an example of a mixture where the physical properties have been modified (completely dissolved)?
Container A, only
Containers A and C
Container D, only
Containers B and D
Simone was helping her father at work. Her task is to separate gravel and sand. The best way for Simone to separate the gravel and sand without using her hands would be –

1. What happens when a small amount of salt and talcum powder mixes with water?
The salt disappears and no longer exists.
The salt mixes with the talcum to create slime.

A chemist added a burst of carbon dioxide gas to a cup of lime water and quickly put a lid on the cup. What happened when the carbon dioxide gas was added to the lime water?
The carbon dioxide dissolved, and the lime water became a lime-tasting soda.
The carbon dioxide turned into a liquid, and the volume of the lime water decreased.
The carbon dioxide sank to the bottom of the cup.
The carbon dioxide floated on top of the water.
Why were these substances placed into these groups?
One group is man-made; the other is natural.
One group conducts electricity; the other insulates.
One group is permanent; the other cycles through nature.
One group is inexpensive; the other is costly.

Point X
Point Y
Point Z
Raphaela is making chocolate milk for her and Shannon. Shannon mentions she drinks her milk with honey instead of milk. What would be the BEST explanation as to why Shannon won't be able to separate the chocolate from the milk?
Why wouldn't someone like chocolate milk?
Because chocolate milk is a solution.
Because chocolate is unable to dissolve in anything other than water.
Because milk is the solute.
These are the correct ways to separate each mixture.
True
False
In a lab, a student added 30 g of solids W, X, Y, and Z to four different glass containers. Each glass container held 200 mL of warm water. The student stirred each mixture for 10 minutes after adding each solid, made an observation, then allowed the mixture to sit undisturbed for 10 minutes. The student's observations are shown in the table. Based on the student's observation, which solid was most likely Kool-aid?
Solid Y
Solid W
Solid X
Solid Z
Four small metal cylinders were filled with boiling water and placed into different containers. The containers were all the same size and shape but were made of different materials. A thermometer was placed in a small opening at the top of each cylinder so that the temperature of the water could be recorded. Results were recorded in the table above. Which container most likely be the best conductor?
Container 1
Container 2
Container 3
Container 4
