Lab Safety
The whole time an experiment is going on
When should we wear goggles in science?
Open the collar all the way
How do we get a roaring flame on a bunsen burner?
Labels and units
Apart from a scale, what does each axis of a graph need?
It describes what we are trying to find out, and includes both the independent and dependent variables
What is the 'aim' in a scientific report?
Under the desks
Where must chairs and bags be when an experiment is going on?
A heatproof mat
What should we always place under a bunsen burner?
If one of the variables consists of words/categories
When would we use a bar graph?
Describing what you learned from the results of your experiment
What does it mean to draw a conclusion?
It might burn/catch fire
Why must long hair be tied back when doing experiments/why must paper be kept away from bunsen burners?
Because it measures more accurately
Why do we measure the volume of liquid using a measuring cylinder instead of a beaker?
Chemistry and Physics
In which sciences would we use scatter graphs?
The dependent variable
What is the variable that we measure in an experiment?
Because it will stay hot for a long time
Why shouldn't we touch a metal tripod after heating a liquid in a beaker?
To separate a solid from a liquid
What would we use a funnel and filter paper for?
If the trend in your data slows down, or the last few points are the same
When would we need a curved line of best fit?
To ensure experimental results are valid
Why do we have control variables/why are there some things we must keep the same in an experiment?
