Which one is for "outstanding" grading (grade 4) in the rubrics?

• The group presented the firework with scientific words and explained them well, so that everyone could understand everything.

• The group spoke with perfect English with native-level pronunciation

• The group presented some information in the PPT, but it is not easy to understand or read what is written.

• The group presented an organized speech, where one person was speaking and the other one helping with the PPT.

An example of oxidizer (releasing oxygen for better combustion) could be:

• ethanol

• charcoal

• iron

• potassium nitrate NaO3

In the oral presentation, for an outstanding grading, the PPT should...

• Have beautiful drawings on it

• be well organized, clear to read and without long sentences to read

• Have a lot of long sentences to show all the information

• Have a lot of complicated information to show that it is complicated science

The best way to improve your English for the oral presentation is...

• to let the best speaker of the group speak all the time

• Practise many times the presentation together with your group

• Practise by yourself and do the whole presentation alone

• Record your presentation at home and show it in class

What improvement could be brought to these classes on Fireworks chemistry?

• There should be more explosions and less colors.

• The students should make a real firework in class.

• The teacher should buy a real huge fireworks and show it as an example
