If my Bunsen burner air hole is closed what kind of flame will I have?

• Safety flame

• Roaring flame

• Luminous flame

• Non-luminous flame

Why should you not heat things using the safety flame?

• They become sooty (carbon deposits)

• They heat too quickly and can cause burns

• They produce harmful gases

• They are difficult to control

For gently heating, which Bunsen burner flame should I use?

• Normal blue

• Safety flame

• Luminous yellow

• Roaring blue

If my Bunsen burner air hole is open what kind of flame will I have?

• Roaring

• Blue

• Yellow

• Flickering

When lighting a Bunsen burner, which position should my air hole be in?

• Open

• Closed

• Partially Open

• Blocked

Draw a tripod

• A three-legged stand used to support a camera or other equipment

• A two-legged stand for holding a microphone

• A four-legged table for dining

• A single pole used for camping

What kind of data is numeric and can have any value within a range e.g. height?

• Discrete data

• Nominal data

• Continuous data

• Ordinal data

Which axis on a graph is the independent variable normally plotted on?

• Y-axis

• Z-axis

• X-axis

• T-axis

True/False - a line of best fit should go from point to point

• True - a line of best fit should connect all points directly.

• False - the line should be smooth and go through as many points as possible.

• True - a line of best fit is a straight line connecting the first and last points.

• False - the line should only touch the highest and lowest points.

The variable we change is known as....

• Dependent variable

• Independent variable

• Controlled variable

• Extraneous variable
