Gravity
This force pulls all objects toward Earth.
gravity
Materials like copper and aluminum are good electrical ________
conductors
A mixture can be separated because does not create a new _____________.
Substance
This force slows down objects when they rub against a surface.
friction
This type of mixture lets you still see all the parts, like fruit salad or cereal.
mixture
When you drop a pencil, it falls to the floor because this force acts on it.
gravity
Materials like rubber and plastic are electrical ________ because electricity cannot flow through them easily.
insulators
Trail mix is an example of this because you can still see and separate the parts.
A ball rolls farther on tile than on carpet because carpet has more of this force.
friction
When you stir sand into water, it does NOT dissolve. This means it is a ___________.
mixture
Gravity affects objects by pulling them in this direction
downward/toward Earth's center
This part of a wire keeps us safe because it is an insulator.
rubber or plastic
When a solid dissolves in a liquid and forms a clear, even mixture, it is called a ________.
When you slide a book across the table, friction makes the book do this
slow down or stop
A solution is created when a solid does this completely into a liquid.
dissolves
When does gravity act on objects
ALL THE TIME
Metal lets heat and electricity pass through easily, which means it is this.
conductor
A mix of salt and water is called a ____________.
solution
This surface would create the least friction: ice, carpet, or gravel?
ice
Name one way to separate a mixture.
sorting/picking them out by hand
If you throw a ball upward, gravity makes it do this after it reaches its highest point.
fall back down
Explain why a metal pot has a rubber or plastic handle.
the handle is an insulator so you don’t burn your hand
Describe one way to separate a mixture of sand and water.
filter
Runners wear rubber-soled shoes because friction helps them do this while they run.
not slip
You can separate a mixture of iron filings and sand using this tool because iron is magnetic.
