Lesson Plan

Who can tell me what a fulcrum point is?

(A fulcrum point is a point or support on which a lever pivots)

Can anyone give me an example?

(A balance, a seesaw...)

Today we are going to balance two objects on a fulcrum point.

Objectives (learning)

The student should be able to balance a spoon and a fork attached to a match on the edge of a cup.

Objectives (teaching)

Students will be engaged in the activity using the materials.

Every student will get the chance to try to balance the objects.

Pre-test

(1 minute)    

Each one of you will have a fork a spoon and a match.

Try to find a way to balance it on the edge of the cup.

Participatory learning

(4 minutes)

Let us try to do it together. We hold a spoon in one hand and the fork in another by their handle.

(I will identify the concave part of the spoon and the inner and outer prongs of the fork to the students).

Now, we insert the middle two prongs of the fork under the concave portion of the spoon and press firmly.

The spoon and the fork should make a V shape like this. We turn the V shape in a way that the open side is towards us.

Now, we insert the bottom of match at the bottom of the fork between the first and the second prong. The match should be facing you.

We hold the other end of the match and try to balance it on the edge of the cup. It works, yippee!!

Post-test

(2 minutes)

Now, let us take the parts apart and let me watch you do it on your own.

Summary

(1 minutes)

Can anyone give me more examples about fulcrum points and balancing object?

What can we conclude from that?
