Science Quiz Questions

You will need to know the answers to the following questions: 

1. What is the definition of matter?

Matter is defined as, anything that has mass and occupies volume/space.

2. What is mass?  Does a substance’s mass ever change?
The mass of an object is a measure of the amount of matter in the object. An object’s mass never changes it, it stays constant everywhere in the universe.

3. What is the formula for calculating the volume of a rectangular solid? 

The formula for calculating the volume of a rectangular solid is this: Volume=length X width X height

4. How is it possible to measure the volume of an irregular solid?

It is possible to measure the volume of an irregular solid if you measure it by the water displacement method.  

Steps:

1. When measuring by displacement you fill a graduated cylinder with water until it is half full.  

2. You record the volume of water in the cylinder or container

3. Carefully add the solid and make sure it is completely submerged in the water.

4. Record the volume of the water plus the solid.  

5. Calculate the volume of the solid by this formula:

volume of solid = volume of water plus solid-volume of water

(You will not need to memorize the steps for the quiz, but it is good to understand them.)

5. What is an everyday situation in which measuring mass and volume is important?

An everyday situation in which measuring mass and volume something like measuring ingredients for baking, as baking requires precise measurement.  Volume is important when courier companies ship boxes and parcels to calculate shipping charges.
