Build a CONNETIX Pulley Machine

By Sarah Shan

Pulleys are fascinating tools that have been used for centuries to make heavy lifting easier. In this blog, we’ll explore how pulleys work, their role in ancient engineering marvels, and their modern-day applications. From the construction of the pyramids to everyday mechanisms like elevators, pulleys demonstrate the power of simple machines in overcoming gravity.

Previously, we delved into the ingenious methods used by the Ancient Egyptians, including simple machines like the pulley—a grooved wheel and rope system that reduces the effort needed to lift heavy loads. By combining multiple pulleys, engineers could minimise the force required, transforming complex tasks into manageable ones.

Today, pulleys remain essential in various industries, from construction to transportation. They operate using kinetic energy, whether pulled by a person or powered by a motor, to lift objects upward with ease.

Building a pulley machine with CONNETIX is a creative and hands-on way for kids to learn about these principles. This activity not only introduces the concepts of effort, load and kinetic energy but also fosters problem-solving and engineering skills in a fun and engaging manner. Let’s get started!

Resources Needed:

Base plate or 12 square tiles
9 Ball run tiles
3 Sraight ball run chutes
4 X 4-Square Rectangle tiles or equivalent in squares
33 Square tiles
Cardboard tube
String
Cup/container
Tape

STEP 1

Build a base level. We used a base plate with rectangles and individual tiles to create a wall and make a tray to catch and contain the rice.

STEP 2

Build the towers. We built five tiles high above the base level. We created a ball run chute down one side with a chute horizontally leaving the bottom of the tower. The other tower was left empty. The top inner tiles on both sides and the outer side of the tower without a chute needs to be a ball run tile with a hole to hold the spool.

STEP 3

Fit the spool. This is to fit the cardboard tube between the two towers, leaving one end out far enough that it can be turned.

STEP 4

Attach a container to the tube using string and tape. The length of string needs to be long enough to travel the distance from the tube to the base tray. Thread the tube through the looped string and tape string to the tube.

STEP 5

Add material. Pour your material into the base form and you are ready to test out your CONNETIX pulley.

STEP 6

Explore! Turn the tube to make the container travel up and down. We filled the container with rice before raising it to the top of the tower to pour it into the ball run chute.

Pulleys offer an excellent opportunity for children to explore the principles of physics while engaging in hands-on learning. By experimenting with different types of pulleys, they can discover how these systems reduce the effort needed to lift or move heavy objects.

Even better, working with pulleys helps develop critical skills like problem-solving and critical thinking. Kids must determine the best way to position the pulley, calculate the force required to move an object, and estimate the movement needed to achieve their goals.

Furthermore, pulleys encourage collaboration; when children work together to build and operate pulley systems, they practice communication and teamwork—essential skills for success in any group activity.

Pulleys in Everyday Life: More Than Just Play!

Pulleys aren’t just a fun way to explore physics—they’re everywhere in our daily lives! These simple machines help make lifting and moving objects easier by redirecting force. You can find pulleys in action in:

Elevators – Using pulley systems to move people and goods between floors.
Cargo lifts – Hoisting heavy items to higher levels with ease.
Wells – Raising buckets of water using a rope and wheel.
Exercise equipment – Creating resistance in cable machines for strength training.

Beyond these everyday examples, engineers harness the power of pulleys in cranes, motors and various tools that shape the modern world. By playing with pulleys, children can develop a hands-on understanding of these essential mechanics, inspiring future problem-solving and innovation!

While pulleys often work behind the scenes, hidden inside machinery, their impact is felt everywhere. By building and experimenting with pulleys using CONNETIX, children not only learn about this essential simple machine but also gain valuable skills that apply far beyond playtime.
