Pludo STEM Winnowing Kit – DIY Wind Grain Machine for Kids 8–11 | Grade 3–5
Spark curiosity about renewable energy with the Pludo STEM Winnowing Kit – DIY Wind Grain Machine for Kids 8–11 | Grade 3–5. This interactive kit helps children understand how wind energy can be converted into motion as they build and test their own mini wind-powered machine.
Designed to make science engaging and hands-on, this DIY Kit encourages creativity, logical thinking, and problem-solving through fun experiments. Perfect for home learning or school activities, it’s a thoughtful addition to any collection of educational toys, helping kids explore real-world concepts through play.
Winnowing Kit Functionality Overview:
- A traditional farm tool used to separate impurities, chaff, and lightweight grains from rice and other crops.
- Also known as a wind grain car, winnowing machine, or windmill.
- A trapezoidal hopper at the top is used to feed grains into the machine.
- Different outlets are provided for clean rice, fine rice, shrunken grains, and chaff.
- A large circular chamber contains an impeller that generates airflow.
- A hand-operated rocker handle rotates the impeller through an iron shaft.
- Faster rotation of the impeller produces stronger wind, while slower rotation generates weaker airflow.
- The airflow carries lighter impurities and chaff away, while heavier grains fall into separate collection areas.
- Feeding hopper, impeller, rocker handle, bellows, grain leakage hopper, air outlet, and discharge funnels.
- One of the most sophisticated and widely used traditional agricultural tools in rural China.
- Efficient grain cleaning, simple manual operation, durable construction, and no electricity required.
