Equipment used to heat things in science.

Hot, clean flame used for heating, produced when the collar is open and more air/oxygen is added, dangerous as it cannot be seen easily.

Orange-coloured flame produced when collar is closed and less air/oxygen, cooler and dirtier than the blue flame, easier to see so safer.

Small metal collar turned to change from orange to blue flame, does not get hot.

Science

In the Solutions unit, pupils will build on their understanding of the states of matter to learn about mixtures, solutions, and dissolving in terms of the particle model.

In Y4 of primary science, pupils learnt about ‘solids, liquids and gases’ and changes of state.

Fill in the blank: A {{}} is used to light a Bunsen burner.

Flame pointing downwards a little and shielded with the other hand

It should never be carried around the lab

Check the collar is in the closed position and the gas tap is off.

Use the nearest lit Bunsen burner to light the end of a splint. 

Walk to your unlit Bunsen burner at a safe speed.

Place your splint near the chimney. Your Bunsen should light an orange flame

Turn the collar to open the air hole to get a blue flame.

Arrange the following actions in the correct order when lighting a Bunsen burner.

Match each of the coloured flames to how open/closed the collar needs to be.
