    In ancient architecture, tools like inclined planes, levers, and pulleys played a vital role. Workers used inclined planes to roll heavy stone blocks upward, pulleys to lift these blocks, and levers for precise placement during temple construction. These simple machines minimized physical effort and enhanced efficiency, making it possible to create massive structures like pyramids and stone temples with limited technology but exceptional engineering skills.

  2. Start by stacking 5–6 ice cream sticks and securing them with rubber bands on both ends. Next, bind two additional sticks at one end to act as the base. Position the stacked set between the two base sticks. Attach an ice cream spoon to the top stick using a rubber band to act as a lever. The catapulRead more

    Start by stacking 5–6 ice cream sticks and securing them with rubber bands on both ends. Next, bind two additional sticks at one end to act as the base. Position the stacked set between the two base sticks. Attach an ice cream spoon to the top stick using a rubber band to act as a lever. The catapult is now ready to launch small objects like paper balls.

  3. To create a robotic arm, pierce the center of ice cream sticks and connect them with toothpicks, allowing flexibility. Add glue for stability at joints. Repeat this process to assemble multiple connected sticks. Attach bottle caps to the ends of the first set for gripping objects. Ensure smooth moveRead more

    To create a robotic arm, pierce the center of ice cream sticks and connect them with toothpicks, allowing flexibility. Add glue for stability at joints. Repeat this process to assemble multiple connected sticks. Attach bottle caps to the ends of the first set for gripping objects. Ensure smooth movement by aligning the sticks properly. The robotic arm simulates a mechanical tool, offering a simple and functional model of a robotic mechanism.

  4. A propeller boat works by spinning paddles attached to a rotating axle, creating thrust in water. To make one, first, paste ice cream sticks in a boat-like structure and make holes to insert axles. Attach bottle caps with slits as paddles to the axles. Secure a rubber band to the boat’s tip and axleRead more

    A propeller boat works by spinning paddles attached to a rotating axle, creating thrust in water. To make one, first, paste ice cream sticks in a boat-like structure and make holes to insert axles. Attach bottle caps with slits as paddles to the axles. Secure a rubber band to the boat’s tip and axle for propulsion. Wind the rubber band, release it, and watch the boat move in water.

  5. The wheel and axle system reduces friction, allowing smoother movement for loads. To make a rubber band car, create a frame using clothes clips. Attach bottle caps as wheels using chopsticks and glue. Secure a rubber band between the back wheels and frame for propulsion. Wind the rubber band and relRead more

    The wheel and axle system reduces friction, allowing smoother movement for loads. To make a rubber band car, create a frame using clothes clips. Attach bottle caps as wheels using chopsticks and glue. Secure a rubber band between the back wheels and frame for propulsion. Wind the rubber band and release it to power the car forward. This simple mechanism demonstrates the practical application of the wheel-and-axle principle.
