Engineering is not just about building machines or designing skyscrapers; it’s a gateway to creativity, problem-solving, and innovation. By introducing children to engaging engineering activities early on, parents and educators can foster a love for STEM (Science, Technology, Engineering, and Mathematics) that will serve them throughout their lives. At The Kids Point, we believe in nurturing young minds by providing exciting, hands-on opportunities to explore engineering concepts while having fun.
Below, we’ve compiled a list of exciting engineering activities that use simple materials and are perfect for sparking creativity in kids of all ages. These projects encourage children to think critically, solve problems, and innovate, all while enjoying the process of building and experimenting.
Build a Marble Run Maze

- Marbles or small balls
Instructions:
- Cut and arrange the cardboard tubes to create a maze.
- Tape or glue the tubes to the cardboard base at various angles to guide the marble’s path.
- Challenge kids to modify their maze to slow the marble down or make it go faster.
Learning Outcome: Children will learn how angles and friction affect the speed and direction of a moving object.
Design a Popsicle Stick Bridge
Objective: Explore structural design and weight distribution.
Materials:
- Popsicle sticks
- Glue or a hot glue gun (with adult supervision)
- Weights (e.g., books or small objects)
Instructions:
- Encourage kids to design a bridge using popsicle sticks.
- Test the strength of their bridge by gradually adding weights.
- Discuss how different designs affect the bridge’s ability to hold weight.
Learning Outcome: Kids will understand the importance of stable foundations and weight distribution in engineering.
Create a Rubber Band-Powered Boat
Objective: Demonstrate propulsion and buoyancy.
Materials:
- Plastic containers or small boxes
- Rubber bands
- Popsicle sticks
- Tape or glue
Instructions:
- Attach a rubber band to a popsicle stick and secure it to the back of the container.
- Wind the rubber band and release it in water to watch the boat move.
- Experiment with different designs to improve speed and stability.
Learning Outcome: This activity introduces kids to the concepts of propulsion and energy transfer.
Construct a Balloon-Powered Car
Objective: Teach about energy conversion and aerodynamics.
Materials:
- Cardboard or plastic for the car body
- Straws

Instructions:
- Build a car using cardboard as the base and bottle caps for wheels.
- Attach a balloon to a straw, securing it to the car.
- Blow up the balloon and let it go, watching the car move.
Learning Outcome: Kids learn about kinetic energy and the role of air pressure in motion.
Build a Catapult
Objective: Introduce principles of force, energy, and trajectory.
Materials:
- Popsicle sticks
- Rubber bands
- Plastic spoon
- Small objects (e.g., pom-poms or marshmallows)
Instructions:
- Assemble a simple catapult using popsicle sticks and rubber bands.
- Attach the plastic spoon as the launching mechanism.
- Test the catapult by launching small objects and measuring their distance.
Learning Outcome: This activity highlights the relationship between force, energy, and distance.
Design a Paper Roller Coaster
Objective: Teach about kinetic and potential energy.
Materials:
- Cardstock or thick paper
- Tape or glue
- Scissors
- Marbles
Instructions:
- Use cardstock to build ramps, loops, and funnels.
- Assemble these components into a roller coaster structure.
- Test how marbles move through the roller coaster, modifying it for smoother rides or faster speeds.
Learning Outcome: Children will learn about energy conversion and the effect of gravity and friction.
Create a Pulley System
Objective: Demonstrate the concept of mechanical advantage.
Materials:
- String
- Spools or small wheels
- A sturdy structure to attach the pulley (e.g., a chair or doorknob)
- Small weights
Instructions:
- Create a simple pulley system using spools and string.
- Use the pulley to lift various weights.
- Experiment with adding multiple pulleys to see how they affect the effort required.
Learning Outcome: Kids will understand how pulleys reduce the effort needed to lift heavy objects.
Design a Water Filtration System
Objective: Teach about filtration and environmental engineering.
Materials:
- Plastic bottles
- Sand, gravel, and activated charcoal
- Coffee filters
- Dirty water (e.g., water mixed with soil)
Instructions:
- Cut the bottom off a plastic bottle.
- Layer sand, gravel, and activated charcoal inside the bottle.
- Pour dirty water through the filtration system and observe the results.
Learning Outcome: Children will learn how filtration systems work and why clean water is essential.
Build a Wind Turbine
Objective: Introduce renewable energy concepts.
Materials:
- Paper or cardstock
- Pencils
- Straws
- Tape
- Small motor (optional)
Instructions:
- Create blades from paper or cardstock.
- Attach the blades to a pencil or straw to form a wind turbine.
- Use a fan or blow air to spin the blades.
- Connect the turbine to a small motor to generate electricity (optional).
Learning Outcome: Kids will understand how wind energy is harnessed and converted into electricity.
Construct a Hydraulic Arm
Objective: Demonstrate hydraulic principles and mechanical movement.
Materials:
- Syringes
- Plastic tubing
- Cardboard
- Tape or glue
Instructions:
- Assemble syringes and tubing to create a hydraulic system.
- Use the hydraulic system to control a cardboard arm.
- Test the arm by picking up small objects.
Learning Outcome: Children will learn about hydraulics and their applications in machinery.
Tips for Parents and Educators
- Encourage Exploration: Let children experiment and learn through trial and error.
- Foster Teamwork: Promote collaboration when working on group projects.
- Ask Questions: Guide learning by asking open-ended questions about their designs and results.
