Learning Objective

2.3 Understanding Inertia

Learning Outcomes

A student is able to:

• explain what inertia is

• relate mass to inertia

• give examples of situations involving inertia

• suggest ways to reduce the negative side effects of inertia.

Solve problems on linear motion with uniform acceleration using

v=u+at

s=ut+ 1

v2=u2+2as

Materials and Apparatus

Hacksaw blade, plasticine balls, G-clamp and stopwatch

Procedure

1. Teacher asks about the inertia to the students.

2. Then, the teacher introduce the topic of the day to the students showing a powerpoint

presentation, for around 25 minutes.

3. Students were divided into 5 groups, each group with 7 students.

4. Each group was given 0.05kg plasticine ball and they fixed it to one end of the

hacksaw blade while other end of the hacksaw blade was clamped to the leg of a table.

5. Students displaced the free end of the hacksaw blade horizontally to one side of the

table and released so that it oscillates.

6. Then, students recorded the time taken for 10 complete oscillations,t1, using a

stopwatch and they repeated the step to obtain the time for 10 complete oscillations for

the seond time,t2. The average value of t1 and t2 is calculated as t.

7. Students determine the oscillation period, T, using T = t

8. Students repeated steps 1,2and 3 using plasticine with masses 0.10kg, 0.15kg and

0.20 kg.

9. Then, the results were prented by the students to the class.

Conclusion

All the total 35 students achived the learning objective. Students are able to

explain what inertia is

• relate mass to inertia

• give examples of situations involving inertia

• suggest ways to reduce the negative side effects of inertia.

Learning Objective

2.1 Analysing electric fields and charge flow

Learning Outcomes

A student is able to :

state the relationship between electron flow and electric current.

define an electric current

describe an electric filed.

sketch electric filed lines showing the direction of the field.

describe the effect of an electric filed on charge.

.

Materials

Cooking oil, talcum powder

Apparatus

Extra High Tension ( E.H.T. ) power supply ( 0 - 5kV ), electrodes with different shapes

( pointed electrode and plane electrode ), a petri dish, connecting wires

Procedure

1. Teacher ask the student what is the relationship between electric field and charge flow.

2. Teacher tells that topic of the day is analysing electric field and charge flow by

showing a powerpoint presentation.

3. Teacher divides the students into 5 groups, with 7 students ina group.

4. Each group were given the materials and apparatus.

5. Teacher set up the apparatus for each group.

6. Then the E.H.T. power supply is switched on and the voltage to 4 kV is adjusted.

7. Then, the movement of talcum powder and the field patterns was oberved by the

students.

8. Students repeat the steps 1 to 3 using the electrodes.

9. Finally every group present their result to the class.

10. Students also recall the activity carried out using a Van De Graff generator to show the

relationship between electric charge and current flow.

I – current

Q - charge

T - time

Conclusion

All the total 35 students achived the learning objective. Students are able to
