Physics team at kibasila sec school made an animation on the Hooke's law of Elasticity. These teachers have never used a computer before for teaching purposes. This lesson is a result of a two days workshop and collaboration in design teams

1. VERIFICATION OF ELASTIC MATERIALS

3. DIAGRAMS Bench Bench Retort stand Retort stand Scale pan Spiral Spring Meter ruler pointer 50g 100g 200g 350g 100cm 1cm

5. TABLE OF VALUES Mass(g) Length(L) Extension(cm) (L-Lo) 50 100 150 200 250 300

7. DURING THE EXPERIMENT Bench Bench Retort stand Retort stand Spiral Spring Meter ruler pointer 60g 61g 62g 63g 64g 65g 66g 67g 100g 150g 200g 250g 300g 350g pointer pointer pointer 50g

10. Table values The original length L o = 61cm AIM ;-To find the relationship between mass and extension of a material Mass, m (g) 50 150 200 250 300 350 Pointer reading, (cm) 62.6 64.0 65.0 66.3 67.5 Extension e=(S-S o ) cm 1.6 3.0 4.0 5.3 6.5

11. A graph of mass (gm) against extension (cm) Scale:- VS 1cm represents 50gm HS 1cm represents 0.5cm 50 100 100 150 200 0 250 300 350 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0 7.5 8.0 * * * * * * Change in mass (gm) Change in extension (cm)

12. 4. From the graph the calculated slope is:- s=change in mass (gm) change in extension (cm) s=350-150 6.5-1.5 s=200 5.0 s=40gm/cm
