BTEC Applied Science Unit 2, Assignment C
(FULL ASSIGNMENT)
What is a hypothesis? - answer-An Idea that you can test using practical
experiments
What are the Key features of a good hypothesis? - answer-A good Hypothesis
must:
Be able to be tested scientifically
Relate one dependent variable to on independent variable
What is a Null Hypothesis? - answer-States that there is no relationship or
causality, for example, no relation between the temperature and the rate of
reaction.
What is a Hazard? - answer-When the equipment or substance can cause
harm, for example a hot plate or hydrochloric acid
What is a risk? - answer-The harm that the hazard could cause and the
chances of it happening, for example the risk of using a hot plate is getting
burnt.
,What is the independent variable? - answer-The variables you change during
an investigation.
What is the Dependent variable? - answer-The variables you are investigating
and measure during an investigation.
What does qualitative data refer to? - answer-It refers to the appearance or
value of something, such as the colour observed or whether the bubbles are
produced.
What does Quantitative data refer to? - answer-It refers to numerical
measurements made, such as the volumes and times measured.
What is SOP? - answer-The Standard Operating Procedure. This is an
established procedure or method used to carry out a routine activity. It
ensures consistent results every time.
What are some examples of SOPs? - answer-Titration, Handling of chemicals,
disposal of waste, qualitative analytical tests, preparing solutions
What are risk assessments? - answer-It identifies hazards, evaluates the risks
associated with those hazards and it determines ways to eliminate or control
those risks.
, What is the control variable? - answer-The variables you keep constant
during an investigation.
What should a method be? - answer-A step-by-step set of instructions, Be
logically ordered, allows you to take sensible measurements, and allows you
to test your hypothesis.
When planning your method what do you need to make sure? - answer-That it
will procedure a range of results, reliable results, precise results, and accurate
results.
What is the accuracy? - answer-How close is the data to the true value? Errors
due to the equipment could make the results less.
What is the reliability? - answer-How trustworthy the data is. It is usually
ensured by repeating the readings to identify any anomalous results.
What is precision? - answer-How close the repeat readings are to each other. It
can be improved by using measuring equipment that measure to more decimal
places.
What is an enzyme? - answer-A protein molecule that acts as a catalyst in a
biochemical reaction.
What do three amino acids form? - answer-A tripeptide
