INSTRUCTIONAL PROCEDURES

PERIOD 1-2

PRESENTATION	TEACHER’S ACTIVITY	STUDENT’S ACTIVITY
STEP 1 INTRODUCTION	The teacher reviews the previous lesson on the Young Modulus	Students pay attention
STEP 2 EXPLANATION	He lists the materials needed and outlines the procedures for the experiment	Students pay attention and participates
STEP 3 DEMONSTRATION	He carries out the experiment and states the observations	Students pay attention and participate

NOTE

MATERIALS REQUIRED -

A spring, a measuring ruler and weights(2kg, 5kg, 8kg and 10kg).

PROCEDURE -

1. Hang a spring from a horizontal metal rod.
2. Attach a mass hanger directly to the bottom of the hanging spring and record the position of the bottom of the mass hanger relative to a meter stick.
3. Hang a weight from the spring and wait for it to come to rest.
4. Record the final position of the mass hanger.
5. Calculate increase in length and and note in the "Observation Table".
6. Repeat the above steps with different weights.
7. Plot a graph with your readings. Force applied (mass X gravity) vs Increase in length (Initial length - Final Length).
