How are magnets used in our everyday lives to solve a problem?
All of the problems listed can be solved with a magnet. When we want to display a picture or holiday card, we can use a magnet on the refrigerator. The freezer door is sealed shut and keeps our food cold when the magnets within are close to each other, and the attraction keeps it closed. If a mixture is presented with metallic objects within the magnet can be used to separate those items based on their magnetic properties. These are simple problems and have a simple solution, magnets!

All of these answer choices are problems that people may be faced with every day, and only one can be solved with a magnet, "Randi dropped paperclips in her water bottle and needs to remove them.". This problem would be solved by putting a magnet near or in the bottle, and the metallic paperclips would be attracted to the magnet, and Randi could pull them out.

A hiker is lost in the woods and needs to get something from his pack to help him find his way back to the campsite.
Which magnetic item could help him solve this problem?
A hiker is lost in the woods and needs to get something from his pack to help him find his way back to the campsite.
Which magnetic item could help him solve this problem?
A magnetic item in his backpack that could help him find his way back to the campsite would be the compass. The other things are helpful during hiking but do not use magnets and would not help him find his way back to camp. A compass uses the Earth's natural magnetic field to point towards the North Pole for people to use as a guide for direction.

What problem is this junkyard magnet solving?
What problem is this junkyard magnet solving?
Junkyard magnets were an ingenious invention that solved a daily problem for the workers. Instead of breaking their backs lifting heavy materials, they were able to steer the magnet, and it could do all the lifting for them. A driver can control the magnet and move cars, scrap metal, and old appliances in seconds. Not only does this save the workers from lifting heavy things, but it speeds up the job too!

Mrs. Addly wants to display her students' work on the metal door for other classes to see. She hangs up the work and uses magnets to keep it in place. Mrs. Addly solved a simple problem using a magnet.

This statement is true. Mrs. Addly did solve a simple problem by using a magnet. Her door was made of metal, so using something like thumbtacks would not work for hanging the students' work. A magnet would be strong enough to keep the papers up and on display, for all to see.

Nadine has a crane with a big magnet. She lowers the crane's magnet over a pile of garbage. Which object(s) are strongly attracted to the magnet?

Magnets attract objects made of certain materials. Objects that are strongly attracted to magnets will stick to them. The plastic fork, sock, and paper plate will not stick to the attraction. These objects are not strongly attracted to the magnet. The metal spoon will stick to the magnet. This object is strongly attracted to the magnet.

Based on the table, which statement(s) is true?
All of the answer choices are correct because they accurately state a fact about magnetic materials. Iron and steel are both magnetic materials and would be attracted to a strong magnet. Plastic, aluminum cans, and cotton are all materials that would not be attracted to a magnet.

Which problem could be solved by using magnets?
The best use for magnets to solve a problem would be securing a broken freezer door. If a magnet is attached to both sides (the door the frame of the freezer) with the opposite sides facing each other, they will be attracted and stick together. Magnets would not keep a dog out of a garden, would not work as a lightbulb, and magnets will not be attracted to a wooden table.

The iron pipe will be strongly attracted to the magnet because it has magnetic properties. Iron is a magnetic metal, so it would be drawn and stick to the magnet. Copper, plastic, and wood are not magnetic and would not be attracted to the magnet.

What could this junkyard magnet pick up that humans can't?
What could this junkyard magnet pick up that humans can't?
Steel objects will be strongly attracted to the junkyard magnet, whereas aluminum, wood, and plastic will not. The magnet will only attract objects with magnetic properties, and of this list, steel is the only object that it would pick up. Steel can be very heavy, and humans cannot easily pick up a large piece by themselves.
