Students performed experiments with three beakers of salt water:
• They placed the first beaker over a magnet.
• They poured the contents of the second beaker through a funnel lined with a coffee filter.
• They heated the third beaker on a hot plate.
Which of the following should the students AVOID while doing these activities?
Read through the steps of the experiment and understand them.
Tell the teacher if a beaker accidentally breaks.
Pull the electrical plug of the hot plate out by pulling on the cord.
Clean up your work area and wash your hands.

Some students were studying the properties of water. A beaker containing 150 mL of water was placed on one hot plate. A second beaker containing 300 mL of water was placed on another hot plate. At the same time, both hot plates were switched on at the same setting. After 12 minutes, both beakers had boiling water in them. Which of the following will be the same for both beakers?
The temperature at which the water boils.
The time it takes for the water to boil.
The volume of water left in the beakers.
The water will physically change from a liquid to a solid.

Bar magnets attract iron.
The S poles of two bar magnets will repel each other.
Look at the picture of the electromagnet. Which of the following is true about electromagnets?
Wrapping the wire around the nail more times will make the electromagnet stronger.
