More dense objects:
Sink
Float
Less dense objects:
Sink
Float
How can we determine whether an object is more dense or less dense?
By comparing the object’s mass to its volume
By checking the object’s color and shape.
By observing if the object sinks or floats in water.
Which example best shows solubility?
Sugar disappearing when stirred into water
A piece of wood floating on the surface of a lake
Sand sinking to the bottom of a glass of water
If a substance is soluble, what does that mean?
It can dissolve in a liquid
It always floats on water
It changes its color when mixed
Which pair shows the best example of an insulator and a conductor?
Rubber gloves and a copper wire
Paper and plastic spoon
Glass and wooden stick
Which statement correctly compares conductors and insulators?
Insulators allow heat or electricity to pass through easily, while conductors block it.
Both conductors and insulators prevent heat and electricity from moving.
Conductors allow heat or electricity to pass through easily, while insulators do not.
Which situation shows the difference between a conductor and an insulator?
A glass of water freezing into ice in the freezer
A metal pan getting hot on the stove while the plastic handle stays cool
A wooden desk staying solid while pencils roll across it
Which item is the best example of a conductor?
A copper wire carrying electricity
A wooden ruler used for measuring
A rubber eraser on the end of a pencil
This is an aluminum washer. Is it less dense or more dense?
Less dense
More dense
Depends
More or less dense?
Less dense
More dense
Less dense or more dense?
Less dense
More dense
A student stirs sugar into a glass of water until the sugar completely disappears.
Which statement best describes what happened?
A mixture was formed because the sugar and water can still be separated with a filter.
A solution was formed because the sugar dissolved evenly in the water.
A mixture was formed because both sugar and water kept their original properties.
A solution was formed because the sugar turned into a new substance.
A student has a cup of salt water and a cup of sand mixed with iron nails.
Which method would best separate each mixture?
Use a filter to remove the salt from the salt water and a magnet to separate the sand from the nails.
Pour the salt water through a sieve and use tweezers to remove the nails from the sand.
Evaporate the water to leave the salt behind and use a magnet to separate the sand from the nails.
A student mixes rice and marbles in a bowl. They want to separate the two materials.
Which method would be the most effective?
Use a sieve to separate the rice from the marbles.
Use evaporation to remove the rice.
Use a magnet to pull out the rice.
Dissolve the marbles in water and filter them out.
