                     In this activity, You will build a giant wheel using bricks and a DC motor. When
                     the motor is powered by a battery, it spins the wheel, making it move just like
                     a real giant Ferris wheel! The wheel will keep rotating until the motor is turned

                     off. This activity helps you understand how motors create movement and how
                     machines work to make objects spin.

                     Concepts

                        • Movement and Motors: You will learn how a DC motor helps things move.

                        Just like the motor in a toy car, the motor in this activity turns the giant
                        wheel. This introduces the idea of how machines use energy (from a battery)
                        to move objects.

                        • Building Structures: By using bricks to create the wheel, You will also learn

                        about construction and balance. The bricks are like the building blocks used
                        in real-life machines and structures.

                        • Electric Circuits: The motor works when the battery powers it. This helps
                        You understand the concept of a simple electric circuit, where the battery
                        provides energy to the motor to make the wheel spin.

                     Observations

                     During the Giant Wheel activity, you will observe how the wheel spins when the

                     motor is turned on. You will notice that the speed of the wheel is controlled by
                     the motor. As you build and test your wheel, you will see how:

                        • The motor makes the wheel rotate.

                        •  The wheel continues spinning as long as the motor is powered by the battery.
                     This activity allows you to explore how motors work and how moving parts in

                     machines are connected to create movement, just like in a real amusement
                     park ride! It also introduces them to how electricity is used to power machines.

                     Creating a Swing

                     Repetitive motion is when an object moves in the same way over and over again,

                     creating a pattern of motion. This type of movement is common in everyday life
                     and is important in many machines and natural processes.

                                                                               Building and Moving Simple Robots  25
