Advanced lesson plan (B2 and above): Is fire a solid, a liquid or a gas? -  BUY ME A COFFEE if you like my FREE ESL content

Remember the last time you sat around a camp fire. Did you wonder what caused that crackling sound? Or why the flames were thin on top and fat at the bottom? Normally, we are too busy chatting, laughing and toasting marshmallows to care. 

In this B2+ worksheet, students will 

• Study a video about the science of campfires;
• Learn fire-related idioms; 
• Do a short exercise about quantifiers (much, many, a lot of, a few); 
• Find the correct punchlines for pun-ny jokes about fire;

Lesson objectives:

1) To find two nouns and three adjectives from a vocabulary list that do NOT describe a photo of a burning forest.

2) To complete a short exercise about quantifiers (i.e. much, many, a lot of, a few).

3) To understand nuance and puns with three fire-related jokes about a hipster, Google and a fire in a shoe factory.

4) To explain the science of campfires and the factors that affect their colour, ferocity and shape using a Ted-Ed video.

5) To expand the students' repertoire of idioms, matching six fire-related idioms/phrasal verbs with their definitions. 

6) To practise reading comprehension by studying an article about "spontaneous human combustion". Is it pseudoscience? Or is it a well-documented and very real phenomenon, as the author Charles Dickens and even some modern scientists argue?
