The document outlines a chemistry lesson plan about fireworks taught by Nithya S Nair to an 8th standard class of 42 students. The 45 minute lesson introduces the topic of firework chemistry through a PowerPoint presentation and video. It explains that gunpowder is a mixture of potassium nitrate, sulfur, and carbon that burns fast to produce gases. Different metal salts are added to gunpowder to produce various colored flames. Through activities and questions, students learn about the chemicals in gunpowder and how different metal salts produce different flame colors.

Name of the teacher: Nithya S Nair Std: VIII Name of the School: GHSS Pallimon Strength: 42 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 a) Executing practical works as per instructions Positive attitudes towards the chemistry of fire works
Different process skills like ACTIVITY 1 After giving a short introduction about chemistry of fire wroks, teacher shows power point presentation ACTIVITY 2 After the presentation teacher shows a video which shows fire works http://youtu.be/CNjggrxUQ78 ACTIVITY 3 After showing the video teacher shows a table Salt Colour Image Barium Light green Calcium Brick red Copper Blue Potassium Lilac Sodium Golden yellow Strontium Crimson red
Lithium Violet Review Questions: 1. What are the chemicals used to make a gun powder ? 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
