Paragraph: (Science-textbook/science-g4-62.txt)
Sent 1: It is not enough to describe some objects by their location.
Sent 2: We may also need to know its direction.
Sent 3: For example, a wind blows a storm over your school.
Sent 4: Where is that storm coming from?
Sent 5: Where is it going?
Sent 6: How can we describe a direction?
Sent 7: The most common way is by using a compass.
Sent 8: A compass is a device with a floating needle (Figure 2.1).
Sent 9: The needle is a small magnet.
Sent 10: The needle aligns itself with the Earth's magnetic field.
Sent 11: The compass needle always points to magnetic north.
Sent 12: If you have a compass and you find north.
Sent 13: You can then know any other direction.
Sent 14: See the directions, such as east, south, west, etc., on a compass rose.
Sent 15: The Earth has two poles.
Sent 16: It has a magnetic north pole.
Sent 17: It also has a geographic north pole.
Sent 18: These two poles are close to each other but not the exact same place.

Question: What are the earth's two poles? (false/additional)

Question: What is the floating needle in a compass made of and which way does it point? (false/additional)

The needle is a small magnet. The needle aligns itself with the Earth's magnetic field.
it's a magnet it always points south
It's a magnet and it always points to the south pole
a metal rod that moves with you
It's a copper rod and points to the geographic north pole
it is a small radio and it points to eaths south.

Question: What two poles are close to each other? (false/challenge)

Magnetic north pole and geographic north pole.
Geographic North pole and magnetic south pole
South pole and North pole
east pole and west pole
north and east

Question: What device has a needle that is a small magnet? (false/challenge)

A compass.
radio
map

Question: What does a compass align itself with? (false/challenge)

The compass needle always points to magnetic north.
Earth's magnetic field.
The compass needle always points to magnetic south.

Question: What might be some characteristics of a storm that we would want to be known? (false/additional)

The storm's direction; where is that storm coming from and where is it going.
the direction of the storm.
where its coming from and going
the face of storm.
The gravity inside the storm

Question: How does a compass work? (false/additional)

A compass has a floating needle, which is a small magnet that aligns itself with the Earth's magnetic field and always points to magnetic north.
a magnet shows north by being aligned with earths magnetic field
The compass needle always points to magnetic north.
The compass needle always points to geographic north.
magic
The compass needle always points to magnetic east

Question: What poles does the Earth have? (false/additional)

The Earth has a magnetic east pole and a geographic west pole.
South Pole and North Pole
east pole and west pole.

Question: What is the most common way to determine direction? (false/additional)

Question: What is a compass? (false/additional)

A compass is a device with a floating needle that is magnetic.
a magnet that shows north
a device with a floating needle
a rod that shows every direction
it is a radio
it is a phone app
it is a website

Question: How does the compass work? (false/challenge)

The magnetic north pole will pull the magnet needle causing it to point north.
by always pointing to magnetic north.
needle points to north
The needle aligns with the position of north
by always pointing to magnetic east.
a rod shows each direction

Question: How can we tell where east, west, and south are with a compass? (false/additional)

are relative to the position of north
based on where north is, which is what the magnet points to
Once the magnet points north we then can read the face of the compass where east, west and south are marked.
the rod shows each direction
west is left
compass always points to east and we can point to other directions.
east is left

Question: What are the two north poles and are they in the same spot? (false/additional)

There is a magnetic and geographic north pole that are very close to each other but not in the same exact spot.
magnetic and geographic north and not the same spot
east pole and west pole and they are on same spot.
north and south and yes the same spot

Question: Why might it be helpful to know direction of a moving object, such as a storm, in addition to its location? (false/additional)

Knowing an object's direction can tell you where it is coming from and where it is going.
so that we can chase it with our car.
research purposes
to assess the depth of the damage.
To find the north pole

Question: What is an instrument used for describing direction? (false/challenge)

A compass.
radio
A phone
A smartphone

Question: What does the magnet in a compass point toward? (false/additional)

Magnetic north.
Geographic north
magnetic south.
both of the north poles

Question: Being able to find north allows you to do what? (false/additional)

to find the other directions.
Find McDonalds
to find the restaurant.
