Build a Brushbot

Project Objective

The primary goal of creating a Brushbot is to introduce children to the basic principles of engineering and robotics in an engaging, hands-on manner. This project aims to spark curiosity about how everyday items can be transformed into simple machines and how these machines can be programmed to perform tasks. By building a Brushbot, kids learn about circuitry, electromechanical, and the use of vibrational energy to propel motion.

How to Build a Brushbot?

1. Materials Needed:

• A small, headless toothbrush (or just the head of a toothbrush)
• A coin cell battery (3V)
• A pager motor or any small vibration motor
• Double-sided tape or hot glue
• Optional: pipe cleaners, googly eyes, and other decorations

2. Assembly Steps:

• Begin by attaching the pager motor to the top side of the toothbrush head using double-sided tape or a small amount of hot glue. Ensure the motor’s wires are facing outward.
• Next, attach one side of the coin cell battery to the top of the motor using double-sided tape, making sure one of the motor wires contacts the top side of the battery.
• Use another piece of tape to secure the second motor wire to the bottom of the battery, completing the circuit. The motor should start to vibrate, causing the toothbrush head to move.
• If desired, use pipe cleaners, googly eyes, and other materials to decorate your Brushbot and give it personality.

Make a Paper Speaker

Project Objective

This project aims to introduce kids to the fundamentals of sound and how vibrations can create audible waves. By creating a simple speaker using basic household materials, children will learn about the principles of electromagnetism and the relationship between electricity and magnetism.

How to Make a Paper Speaker?

1. Materials Needed:

• A paper or plastic cup
• A coil of copper wire (at least 20 feet)
• Strong magnets (at least two)
• Tape or glue
• An audio source (e.g., phone, laptop, MP3 player)

2. Assembly Steps:

• Begin by creating a small hole in the bottom centre of the cup.
• Thread one end of the copper wire through the hole, leaving a small amount sticking out on either side.
• Use tape or glue to secure the magnets to the sides of the cup directly below the hole. The magnets should be placed vertically with their north and south poles facing each other.
• Wrap the remaining wire around the cup tightly in a spiral pattern, ensuring it stays close to the surface of the cup.
• Connect the exposed ends of the wire to the audio source, and test your paper speaker by playing music or sound effects.

Design a Paper Tower

Project Objective

This project introduces kids to structural engineering and how different shapes, materials, and techniques can affect a building’s strength and stability. By designing their paper tower, children will learn about the forces of tension and compression and the importance of a sturdy base.

How to Design a Paper Tower?

1. Materials Needed:

• Sheets of paper
• Tape or glue

2. Assembly Steps:

• Begin by folding one sheet of paper into a long, thin strip. This will be used as your tower’s base.
• Start building your paper tower by placing the folded strip in an “X” shape on a flat surface.
• Attach additional sheets of paper to the corners of the “X,” creating a pyramid-like structure. Use tape or glue to connect the documents and ensure they are tightly secured.
• Continue adding layers to your tower, alternating between horizontal and vertical orientations. Make sure to connect each new layer to the previous one securely.
• Test your tower’s stability by placing small objects on it, such as coins or paper clips. See how high you can build your tower without it collapsing!

Create a Leak-Proof Boat

Project Objective

This project aims to introduce kids to buoyancy and how it can help objects float on water. By creating a leak-proof boat, children will explore different materials and their properties while learning about engineering design principles.

How to Create a Leak-Proof Boat?
