INDUCTIVE THINKING MODEL

Name of the school :                                        STANDARD :❾ Name of the teacher: Fareeda Beegum .R.S     DATE : Subject: Physics Unit : Fluid Topic :Viscosity

Name of the concept: Viscosity

Objectives:

· Pupils develop observation skills.

· Identification of different types of viscous liquids.

· Generalization about the property of viscous liquids.

· Pupils develop hypothesizing predictive result.

PHASE :1 Data Categorizations :

T: What is the common property of water, acid, honey, etc?

S: They are all liquids.

T: Can you name some of the liquids that we use in our daily life?

S: Yes. Coconut oil, ghee, shampoo, nail polish, spirit, viniger, well water, petrol etc.

T: Can you group examples and name according to their similarity?

GROUP A	GROUP B
Castor oil Coconut oil Ghee Shampoo Nail polish	Well water Spirit Viniger River water petrol

PHASE: 2 Interpretation of data :

T: Let me analyze each group of examples and know more about them.What is the peculiarity of liquids in group A?

S: They all are liquids.

T: Anything else.

S: They flow very slowly.

T: YES. You are right.They are called viscous liquids.what about group B?

S: Group B flow faster.

T: Yes. They are called mobile liquids. Can you identify the property of viscous liquids?

S: No teacher.

T: Yes. It is called viscosity. it is the property of liquids which opposes the relative motion between

Different layers of liquids. Thus viscous liquids have high viscosity and mobile liquids have low viscosity.

PHASE: 3 Application of generalization:

T: Now I will give you examples of different types of liquids .you must name its name its type. Dettol.

S: mobile liquids.

T: Why it is a mobile liquid?

S: It is because it got low viscosity.

T: Yes .now Starch.

S: It is viscous liquid.

T: Why it is a viscous liquid ?

S: It is because it got low Viscosity.

T: Yes. Tar.

S: viscous liquid.

T: Lemon water.

S: mobile liquid.

T: Yes. Viscosity is the property of liquids, which opposes the relative motion between

Different layers of liquids.Liquids having high viscosity are called viscous Liquids.

           Liquids having low viscosity are called mobile Liquids.
