This LEGO STEM Challenge is a fun and unique activity for kids. With just legos and water, kids will have a blast making a boat that floats and carries things!
- Total Time5 + play time
Materials
● LEGO bricks (a mix of sizes and shapes)
● A large bin or container filled with water
● Small objects to use as “cargo” (e.g., coins, buttons, glass pebbles, etc)
● Towels for drying off
Instructions
1. Build: Kids design and build their own boats using LEGO pieces. Encourage different shapes and structures.
2. Float Test: Place the boats in the water to see if they float. If not, they can rebuild and try again!
3. Cargo Challenge: Once the boats float, add small “cargo” items one by one to see how much each boat can hold before it sinks.
4. Experiment: Let kids modify their boats. Maybe making them smaller, wider, longer, heavier, or lighter. Then compare results.
