QUESTIONS AND ANSWERS
What is a hypothesis? - correct answer- An Idea that you can
test using practical experiments
What are the Key features of a good hypothesis? - correct
answer- A good Hypothesis must:
Be able to be tested scientifically
Relate one dependent variable to on independent variable
What is a Null Hypothesis? - correct answer- States that there
is no relationship or causality, for example, no relation between
the temperature and the rate of reaction.
What does qualitative data refer to? - correct 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? - correct answer- It refers
to numerical measurements made, such as the volumes and
times measured.

What is SOP? - correct 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? - correct answer- Titration,
Handling of chemicals, disposal of waste, qualitative analytical
tests, preparing solutions
What are risk assessments? - correct answer- It identifies
hazards, evaluates the risks associated with those hazards and
it determines ways to eliminate or control those risks.
What is a Hazard? - correct answer- When the equipment or
substance can cause harm, for example a hot plate or
hydrochloric acid
What is a risk? - correct 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? - correct answer- The
variables you change during an investigation.
What is the Dependent variable? - correct answer- The
variables you are investigating and measure during an
investigation.
What is the control variable? - correct answer- The variables
you keep constant during an investigation.
What should a method be? - correct 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? -
correct answer- That it will procedure a range of results, reliable
results, precise results, and accurate results.
What are some types of data? - correct answer- The data can
be continuous such as the age of plant ir number of plants.
Some data can be a mixture of numbers and names such as
the number of different types of plants found in a garden.
