Magnetism Basics
This is the force that a magnet exerts on certain metals without touching them.
What is magnetic force?
Gravity acts on all objects, causing them to do this when dropped.
What is fall (or accelerate downward)?
In an experiment, you guess what might happen based on what you know. This is called a [blank].
What is a hypothesis?
This is an example of a non-contact force that pulls objects toward the Earth.
What is gravity?
Rubbing a magnet on a metal object for several minutes will likely cause the object to become this.
What is magnetized?
Magnets have two of these, one labeled "N" and the other labeled "S."
What are poles?
The force of gravity pulls objects toward this part of the Earth.
What is the center of the Earth?
At the end of an experiment, you should explain what happened and what your data means. This is called [blank].
What is drawing a conclusion?
This force can push or pull an object without touching it and is responsible for magnets sticking to the fridge.
What is magnetic force?
If you bring the north pole of one magnet near the south pole of another magnet, they will [blank].
What is attract?
As the distance between a magnet and a metal object decrease, the strength of the magnetism will [blank].
What is increase?
On the Moon, gravity is only about one-sixth as strong as Earth's. This is why astronauts on the Moon appear to do this.
What is jump higher (or move with less effort)?
To make sure your data is reliable, it's important to do this many times.
What is repeat the experiment?
In a game of tug-of-war, the force you use to move the rope toward you is an example of this kind of force.
What is a pulling force?
When you bring two north poles of magnets close together, they will [blank].
What is repel?
Magnets are used in this common object to help it stick to metal surfaces.
What is a refrigerator or whiteboard magnet?
Gravity is responsible for keeping this planet and all other planets in orbit around the Sun.
What is Earth (or the Solar System)?
In an experiment, you need to measure things like temperature or time. What do you need to use to do this correctly?
What are tools (like a thermometer or stopwatch)?
Non-contact forces, like gravity or magnetism, work by pulling or pushing objects without this.
What is touching?
A compass needle always points in this direction due to the Earth's magnetic field.
What is North?
If you move a magnet away from a metal object, this happens to the magnetic force.
What is it gets weaker?
This effect of gravity causes objects to fall at the same rate, regardless of their [blank], when dropped from the same height.
What is weight or mass?
You can calculate the [blank] after repeating an experiment multiple times to this help make your data more reliable.
What is average?
When you use your hands to move a box across the floor, you are applying a force that makes the box move away from you.
What is a push force?
This term describes the region around a magnet where its magnetic force can be felt.
What is the magnetic field?
