How To Draw A Line Graph; How To Design A Fair Test; The Impact Of Materials On The Environment

Question 1

What is a graph?

Answer 1

A drawing that shows information in a way that makes it easier to understand

Question 2

Why are graphs useful?

Answer 2

They make it easier to interpret the information and see if there are any patterns in the information

Question 3

Define independent variable.

Answer 3

Variable that is not affected by other variables, for example, time

Question 4

Define dependent variable.

Answer 4

Variable that changes according to the independent variable, for example, the size of a growing plant will depend on hpw much time has passed

Question 5

In a line graph which axes is horizontal? (Going sideways)

Answer 5

The x axes

Question 6

In a line graph which axes is vertical? (Upright)

Answer 6

The y axes

Question 7

Which axes is the independent variable and which is the dependent variable?

Answer 7

The y axes is the dependent variable
The x axes is the independent variable

Question 8

What is a fair test?

Answer 8

Test in which the conditions are the same for all the different objects or cases you are going to test

Question 9

Define factor.

Answer 9

One of the different conditions in your test, for example, temperature, time, weight, strength, colour are all factors that could affect the results

Question 10

Manufacturing processes use energy and often cause pollution. For example…

Answer 10

Mining uses a lot of energy, that can cause environmental damage. When we dispose of metal goods like old washing machines or cars they cause pollution.

Fuels are usually obtained from oil. Extracting oil from the ground causes huge pollution problems. When we burn feuls, we release gases that are very harmful to the environment.

Once we have finished with things, we usually dispose of them. The disposal landfill sites are full of plastic that cannot be recycled
