Subject: Chemistry Duration: 45 min
Unit: Changes Date: 12th July 2014
Topic: Chemistry of fire works
CURRICULAR STATEMENT
Through experiment, observation and discussion pupil understatnds about fire work
CONTENT ANALYSIS
Term: Fire works
Facts:
 Gun powder is the mixturemade by mixing potassium diamide, powdered sulphite and carbon
powder
 Burning of gun powder is a fast process and a lots of gases are formed
CONCEPT
Chemicals added with the gun powder to give beautiful colours to the flame. Salts of different metals ae
added for this purpose
Learning outcome:
Pupil enable to develop
 Factual knowledge on th topic, the chemistry of fire works
a) Facts and terms mentioned in the content analysis
b) Recognising different concepts related to fire works
 Conceptual knowledge about the chemistry of fire works
a) Recalling changes
b) Recognising diffrent concepts related to fire works
 Procedural knowledge about the chemistry of fire works
a) Executing practical application about fire works
 Meta cognitive knowledge about the chemistry of fire works

2. Find out the colour of the flame if we add
a) Lithium
b) Strontium
c) Potassium
3. How varoius colours are given to the fire works?
Follow up Acitivity
Prepare a short note about the chemistry of fire works
Self reflection
This topic was done in the IT labby presenting slides about the chemistry of fire works. Pupils enjoyed
this portionand I showed a small video about the fire works. By showing different pictures of fire worksI
catogorised the salts and colour to the flame. So it was easy for me to convince the topic through slide
presentation
