The gravity-powered generator model demonstrates how gravitational potential energy can be converted into electrical energy.
A weight is lifted to a certain height and then allowed to fall, pulling a string connected to a pulley.
The pulley rotates a small motor, which can act as a generator to produce electricity.
This project helps students understand energy conversion and the working principle of a simple generator.
It is an educational model that demonstrates renewable energy concepts, although continuous electricity generation requires the weight to be lifted again.

NEEM WOOD

3D Geometry Shapes – Neem Wood is a handmade educational model created using natural neem wood.
It represents common 3D shapes such as cube, cuboid, cylinder, cone, sphere, and square pyramid.
Each shape is clearly displayed with its corresponding name for easy identification.
The model helps students understand three-dimensional shapes and their physical properties through hands-on learning.
I made this model to make geometry learning simple, practical, and visually interesting.

This working science model demonstrates an Automatic Water Dispenser designed for touch less and efficient liquid dispensing.
Built on a wooden base board, it uses a white PVC pipe frame and clear vinyl tubing connected to a water reservoir container.
It features an IR sensor / relay module setup powered by a battery to detect objects placed on the red landing plate automatically.
When a glass or hand is detected under the spout, the circuit triggers a mini DC submersible pump inside the bucket to draw water.
It serves as an ideal hands-on STEM school exhibition model to demonstrate automation, sensor technology, and water conservation
