Elasticity Part 2, From Prob.-Based Learning to Project-Based Learning

.......... continued..

Previously in Part One, Student are given a  Problem-Based Learning  (Oh Poor Chicken!) for them to work on it, discuss, cooperate and collaborate in groups to find an open ended answer or solution.

Students are required to present their findings in a form of paper presentation and a product; which is a catapult itself.

A catapult / slingshot assigned  to each groups

    Problem-Based to Project-Based Learning

Problem-BL : Solve a specific problem
Project-BL   : Build a model based on the project

Awww yess... dont ever think  that school girls are obedient all the time. For those who did complete their task, there n then the are instructed by the teacher to produce the product with materials they can find around the school

Experimenting, measure the extension of the rubber  when given certain Force acting on it. Data is tabulated in a table.

Let them play for a while and find the longest distance the pebble can fly with 3 trials.
Aim: To relate the value of k to the distance of pebble.

The materials for the experiment. Mythbuster!

Plotting graph of F against x to find k and later.... find Energy of the rubber. (Area under graph)
