This document provides instructions for building three DIY projects: a dynamo, motor, and lie detector. For the dynamo, children can learn about generating electricity from kinetic energy using a pinion gear and rotor to control light intensity. For the motor, the document explains how motors work everywhere from fans to cars, and allows learning what parts are required to build one. The lie detector project teaches about measuring physiological signals like pulse and skin conductivity to detect deception.

13. Do It Yourself (DIY)

14. It is designed to produce electrical energy
from mechanical energy. Children learn
the benefits of kinetic energy as instead
of battery a dynamo is producing voltage.
This kit includes pinion and gear i.e., a
rotating wheel with cut teeth which
mesh with another toothed part to
transmit the power The speed of the
rotor controls the intensity of the light.
The kit is useful to learn how the
electricity is generated.
Learn how Dynamo works, and the
name of the parts required to build a
Dynamo (Build Your Own Dynamo)

15. Build Your Own Motor.
Motor is everywhere. In a fan there is a
motor, in a car there is a motor, in an electric
razor there is a motor.
But how it works?
What are the parts required to build a motor?
Do It yourself (DIY)
MOTOR
Know about the relationship between electricity and
magnetism. Learn how the interaction of electricity and
magnetism can convert electrical energy to rotational
mechanical energy. Know about the basic structures and the
working principles of a motor.
