Question 23

What is the tool we’ll use to find information of an area you are researching?

Answer 23

• field guide

Question 24

What is a hand lens and how do we use it in science?

Answer 24

A hand lens is a magnifying glass, a portable tool for examinating things. It makes things look larger, but not as much as a microscope does.

Question 25

What is a microscope?

Answer 25

A microscope uses a series of lenses that make objects appear larger. You can adjust the position of the lenses to change the amount you magnify the object.

Question 26

What is a stop watch?

Answer 26

A stopwatch is a watch with a hand that can be stopped or started. It is used for timing experiments.

Question 27

What is a metric ruler?

Answer 27

A metric ruler or meterstick is used to measure length. A meterstick is one meter long. The stick is divided into centimeters and millimeters.

Question 28

What is a graduated cylinders?

Answer 28

Graduated cylinders and beakers can be used to measure volume, or the amount of space an object takes up.

Question 29

What is a camera?

Answer 29

Cameras can be used to take pictures of objects. Pictures help you record and compare objects and observe changes.

Question 30

What is a thermometer?

Answer 30

A thermometer is used to measure the temperature of an object. The liquid (mercury) in the thermometer expands when both get warmer and contracts when both cool. This causes the liquid to move up and down the temperature scale. In the Celsius scale, 0° represents the freezing point of water, and 100° represents the boiling point of water.

Question 31

What is a balance?

Answer 31

A balance is used to measure mass. To find the mass of an object, add standard masses to the pan opposite the pan holding the object. When the two pans are at the same level, the sum of the standard masses equals the mass of the object.
