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.
What data is normally displayed on a bar chart? - CORRECT ANSWER✔✨-Continuous data. You need
to make sure its a smooth curve of best fit, and that the curve goes through or near most of the points.
What are bar charts used for? - CORRECT ANSWER✔✨-They are used for discrete data but can be
used to compare different sets of data.
