Bunsen Burner

James, Abigail, and Grace are having a debate in their science class. They are discussing why press studs are used in a lab coat. Can you help them settle this?

• They believe that press studs are unlikely to fall off

• They think it makes it easy to remove your lab coat quickly if there is a hazard

• They argue that press studs are cheaper to produce than buttons

• They suggest that press studs improve the look of the lab coat

Abigail, Samuel, and Elijah are in a science lab, experimenting with a bunsen burner. They discovered that they can adjust the heat on the bunsen burner by turning the what?

Kai, Elijah, and Arjun are having a science experiment. They need to use a bunsen burner. What should they put under the bunsen burner before they start?

• heat proof mat

• gauze mat

• tripod

• peg

Ava, Aiden, and Isla are in a science lab. They are about to perform an experiment that requires the use of gas. When should they turn on the gas?

• As soon as they enter the lab

• Before they light the match

• After they have lit the match and are holding it above the barrel

• At the end of the prac

Imagine Benjamin and Kai are in a science lab, ready to light up the bunsen burner for an exciting experiment. Zoe asks, 'What should they do with the airhole before lighting the bunsen burner?'

• Open it

• Close it

Nora, Anika, and Elijah are in Science class and are experimenting with the bunsen burner. Nora wonders, 'If we close the airhole, what colour will the flame be?'

• blue

• yellow

• red

• purple

Zoe, Aria, and William are having a debate. Zoe says the yellow flame is the safety flame because it's easier to see and less hot than the blue. Aria thinks it's because it's easier to see and more hot than the blue. Who do you think is correct?

• Zoe's argument: It is easier to see and less hot than the blue

• Aria's argument: It is easier to see and more hot than the blue

James and Avery are having a debate. James thinks the blue flame is for safety, but Avery believes it's for heating. William, on the other hand, thinks it's for cooling. Who is correct?

• James, because the blue flame is the safety flame

• Avery, because the blue flame is the heating flame

• William, because the blue flame is the cooling flame

• None of them, because the blue flame is the "no heat" flame

Imagine Avery, James, and Arjun are in a science lab. They are experimenting with heating elements and suddenly they divert their attention away from what they are heating. What should they do next?

• Close the airhole, so the yellow safety flame reappears

• Open the airhole

• Ensure the flame is blue

• Nothing - it will be fine

Lily, Hannah, and Samuel are in the science lab. They've just finished an experiment and it's time to clean up. How should they turn off the bunsen burner?

• Turn off the gas

• Unplug it from the wall

• Blow it out like a birthday candle

• Just walk away and let it burn
