2. LESSON PLAN ON
Subject- Physical Science Grade- VIII Topic- Archimedes Principle Duration- 1 hrs.

3. Teaching Points: Upward thrust of fluid Concept of Buoyancy
Floating of an object
Upward thrust of fluid
Concept of Buoyancy
Condition for Floating
Archimedes Principle

4. Learning Objectives: Immersion & Floatation of different objects.
Upward thrust experienced by an object
Real life experience of Buoyancy
Condition of Floatation
Archimedes Principle

5. ICT TOOLS USED: World wide web (internet navigation) Video clips
Digital concept mapping
You-tubes
Wall wisher

6. Learning Strategy: 5E’S Learning Model
E1 Engagement Phase E2 Exploration Phase E3 Explanation Phase E4 Elaboration Phase E5 Evaluation Phase

7. Engagement Phase:Situation-1
View the video clip of Floating of Titanic
View the video clip of Sinking of Titanic
View the video clip of Floating a Cauldron

8. Questions to Students:
In video clip the Floating of Titanic, how a large and weighty ship like Titanic can float on sea?
In the video clip of the Sinking of Titanic, what happened to the ship and why?
In the video clip of the Floating of Cauldron, how a cauldron can float but a small piece of Iron can not.

9. Students Observation:
Every object can not float
While floating object experiences an upward thrust i.e. Buoyancy.
Floating is possible only when buoyancy is greater than or equal to the weight of the object.
Buoyancy is the property of fluid.
While an object is emerged into the fluid it experiences an apparent loss of weight.
Apparent loss of weight of an object is equal to the weight of fluid replaced.

10. Situation-2
Teacher will post on wall wisher about the floatation & emersion of different objects that is used in real life situation & working principle of submarine.
Collaborative digital concept map on natural rules of floatation.
Students may be explored to observe the following images of the famous historical perspective & the situation of “Eureka…Eureka” & experimental setup for verification of Archimedes Principle.

11. Concept Mapping-1: Submarine

12. Concept Mapping-2:Golden Crown

13. Concept Mapping-3:Eureka…

14. Questions to Students:
Why some objects can float but some can’t?
In case of floatation what is the relation between apparent loss of weight of an object and the weight of fluid displaced by the object ?
Is Buoyancy applicable for the air also?
Why animal can float and human is to learn floating?

15. Students Observation:
Object for which the weight of displaced fluid is greater than or equal to its true weight can float only, Others can not.
In case of floatation, apparent loss of weight of an object is equal to the weight of fluid displaced.
Buoyancy is also applicable for air.
 Buoyancy is different for different fluid.

17. Archimedes Principle
An object, immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. This became known as Archimede's principle.
The weight of the displaced fluid can be found mathematically. The fluid displaced has a weight W = mg. The mass can now be expressed in terms of the density and its volume, m = dv. Hence, W = dvg.

19. Explanation Phase:
The teacher will be explaining those concepts/ ideas in this lesson depends on students misconceptions/ alternative conception arises during the engagement and the exploration phases.

20. Elaboration Phase:
In this topic students may be assigned on the following tasks and may be allowed for optimum use of different tools of ICT.
Conduct a survey for floating of same object in different fluids through the internet search.
Solve different types of numerical problems based on Archenemies Principle.

21. Evaluation Phase:
Evaluation, the fifth ‘E’ is an ongoing diagnostic process
Some of the ICT tools that assist in this diagnostic process are: e- portfolio, digital mapping, web quest and assignment etc.
