what is a graph?

How do you check your results

what are variables?
The elements that change in an experiment are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types.

to represent our results and see if there are any anomalies in our results so if there is, we can redo our practical
what is a conclusion?
a summary of an experiment
what is the 5th step in the scientific method?
collect data
how can variables change a practical result
Researchers often manipulate or measure independent and dependent variables in studies to test cause-and-effect relationships.
What variables go on the x and y axis
x: independent variable y: dependent variable
why are conclusions useful
to show a reader how a practical went.
why do we need to do a risk assessment in an investigation?
to make sure it's safe
what is the DV in the time taken for a toy car to go down a ramp with weights?
time taken for the car to go down (s)
how many types of graphs are there?
how can conclusions benefit a practical?
It can tell someone what happened in a practical and how it went
A conclusion is a call to action and brings a written composition to a logical close.
