Join Lebo and Sipho on an educational adventure as they discover the hidden physics in their everyday world. Through clever problem-solving and simple machines, these two friends show young readers how science can turn a giant obstacle into a brilliant discovery. It is a perfect blend of friendship and foundational engineering concepts for curious minds.
Lebo and Sipho were walking home from school when they found a huge rock blocking the pathway. Lebo smiled, remembering their science lesson, while Sipho wondered how they could ever move such a heavy object.
Lebo knelt down and drew a simple diagram in the soft sand with a twig to explain the secret of the lever. He showed Sipho that they needed a pivot point called a fulcrum, a heavy load to move, and the effort of their own strength.
Lebo found a sturdy wooden branch and placed it over a small, sharp rock to create a first-class lever. As he pushed down with all his might on one end, the giant boulder on the other side slowly began to rise.
A long, straight wooden bar is balanced perfectly on a small triangular stone placed right in the middle. A heavy round stone sits on the left side of the bar, while a glowing energy pulse on the right side indicates where the force is applied.
Later that day, Sipho helped his mother by pushing a wheelbarrow filled to the brim with heavy, colorful vegetables. Lebo pointed out that the wheelbarrow is a second-class lever because the heavy load rests in the middle of the frame.
An illustration shows a long beam with a wheel acting as a pivot point at the very front end. A large, heavy crate sits in the middle of the beam, and an upward lifting force is shown at the handles on the opposite end.
At the local park, Lebo used a pair of long metal tongs to carefully pick up pieces of litter from the grass. He explained to Sipho that tongs are third-class levers where the effort is applied in the middle to give them more precision.
This illustration shows a tool with a hinge at one end acting as the pivot point and a small object being held at the very tip. The squeezing force is applied directly to the center of the tool's handles to show how the mechanism works.
The two friends sat together on a park bench, looking at all the tools around them like fishing rods and nutcrackers. Lebo explained that every lever has a special job, whether it is making a load feel lighter or giving someone more control over a task.
Sipho and Lebo stood proudly on the now-clear path, feeling like true heroes of science. They realized that levers are everywhere in their daily lives, helping them solve problems and move the world one pivot at a time.

SECTION B: NARRATIVE ARTEFACT ON LEVERS (20 MARKS) Title: “The Lever Heroes: Lebo and Sipho’s Big Discovery” Page 1: Introduction (Story Begins) Lebo and Sipho were walking home from school when they found a huge rock blocking the pathway. “Oh no! How are we going to move this?” Sipho asked. Lebo smiled. “Remember what we learned in class today? We can use a lever!” “A lever?” Sipho asked, confused. “Yes,” said Lebo. “A lever is a simple machine that helps us lift or move heavy objects more easily using a bar and a pivot point.” Page 2: What is a Lever? (Concept Explanation) Lebo drew a diagram in the sand and explained: “A lever has three important parts: The Fulcrum – the point where the lever pivots The Load – the object being moved The Effort – the force you apply Levers help us by giving us something called mechanical advantage, which means we can use less effort to move a heavy load.” Page 3: First-Class Lever (Story + Example) Lebo placed a stick over a small rock. “Look, Sipho! The rock underneath is the fulcrum, the big rock is the load, and when I push down, that’s the effort.” Sipho watched as the rock lifted. “That’s amazing!” “This is called a first-class lever,” Lebo explained. “The fulcrum is in the middle.” Example in real life: Seesaw, crowbar Page 4: First-Class Lever Diagram (You must draw this in Canva) 👉 Draw and label clearly: A straight bar Fulcrum in the middle Effort on one side Load on the other side Labels: Fulcrum (middle), Effort (one side), Load (other side) Page 5: Second-Class Lever (Story + Example) Later, Sipho helped his mother carry vegetables using a wheelbarrow. “Hey Lebo!” Sipho shouted. “Is this also a lever?” “Yes!” Lebo replied. “This is a second-class lever. The load is in the middle.” “So that’s why it feels easier to carry heavy things!” Example in real life: Wheelbarrow, bottle opener Page 6: Second-Class Lever Diagram 👉 Draw and label: Fulcrum at one end Load in the middle Effort at the other end Labels: Fulcrum → Load → Effort Page 7: Third-Class Lever (Story + Example) At the park, Lebo picked up litter using tongs. Sipho asked, “Is that also a lever?” “Yes,” Lebo said. “This is a third-class lever. The effort is in the middle.” “But it feels harder!” “That’s because this type gives more control and movement, not force.” Example in real life: Tweezers, fishing rod, human arm Page 8: Third-Class Lever Diagram 👉 Draw and label: Fulcrum at one end Effort in the middle Load at the other end Labels: Fulcrum → Effort → Load Page 9: Mechanical Advantage Explanation Lebo explained: “Mechanical advantage means a machine makes work easier. First-class levers can change direction Second-class levers make lifting easier Third-class levers help with speed and control That’s why different levers are used for different jobs!” Page 10: Conclusion (Story Ending) Sipho smiled. “Wow, levers are everywhere!” “Yes,” Lebo said proudly. “We use them every day without even noticing.” From that day on, Sipho and Lebo became known as the Lever Heroes, always using science to solve problems!
