Topic- Archimedes Principle

Duration- 1 hrs.

Teaching Points:

Floating of an object

Upward thrust of fluid

Concept of Buoyancy

Condition for Floating

Archimedes Principle

Learning Objectives:

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

World wide web (internet navigation) Video clips Digital concept mapping You-tubes Wall wisher

Learning Strategy: 5E’S Learning Model

E1 Engagement Phase

E2 Exploration Phase

E3 Explanation Phase

E4 Elaboration Phase

E5 Evaluation Phase

Engagement Phase:Situation-1

View the video clip of Floating of Titanic www.youtube.com/watch?v=5OJz78huz78

View the video clip of Sinking of Titanic www.youtube.com/watch?v=1avWJELB9Ek

View the video clip of Floating a Cauldron www.youtube.com/watch?v=lK4fWfZknBY

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.

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.

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.

Concept Mapping-1: Submarine

Concept Mapping-2:Golden Crown

Concept Mapping-3:Eureka…

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?

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.

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.

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.

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.

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.
