Archimedes’ Screw Model STEM Lab Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12515
Introduce students to the engineering marvels of antiquity and the physics of fluid mechanics with the Archimedes’ Screw Model STEM Lab by Educational Instrument India. As one of the earliest recorded positive displacement pumps, invented by Archimedes of Syracuse in the 3rd century BCE, this apparatus provides a dynamic, hands-on demonstration of how rotational energy can overcome gravity to lift liquids or granular solids.
This high-quality STEM lab model is meticulously tailored for primary science classrooms, secondary physics labs, and historical engineering workshops. By transforming rotational kinetic energy into the potential energy of water students gain an intuitive grasp of mechanical advantage, work, energy transformation, and the design principles behind modern agricultural and waste management systems.
Key Features & Benefits
High-Transparency Design: Features a crystal-clear outer cylinder that allows students to observe the internal helical flighting in real time, tracking the movement of water or beads as they ascend.
Ergonomic, Low-Friction Hand Crank: Outfitted with an ultra-smooth manual turning crank handle, making it easy for students of all ages to achieve stable, consistent rotational speed.
Dual-Purpose Media Kit: Optimized to lift both liquids (colored water) and small particulates (plastic beads, peas, or sand), illustrating the versatile applications of actual industrial screw conveyers.
Complete STEM Learning Module: Comes with a lower feed reservoir, an upper discharge catch basin, and a comprehensive experiment guide designed to promote inquiry-based scientific exploration.

How to Use It: Step-by-Step Guide
Follow these foundational steps to demonstrate fluid transport efficiency using the Archimedes' Screw model:
Assemble the Lab Station: Place the heavy structural base on a stable, flat surface. Position the lower reservoir at the bottom and fill it with colored water or small plastic beads.
Set the Angle of Inclination: Secure the screw cylinder onto the support mounts. Start with an optimal angle of inclination of around relative to the horizontal table surface.
Position the Catch Basin: Place the empty discharge collection cup directly under the upper outlet nozzle of the tube.
Operate the Crank Handle: Rotate the hand crank in a steady clockwise direction. Watch closely as the bottom tip of the helical screw scoops up small pockets of water or beads during each revolution.
Observe the Trapped Pockets: Point out to students how the media stays trapped within the moving pockets formed by the helix and the tube wall, moving upward without sliding backwards.
Experiment with Variables: * Increase the angle of inclination past and observe how the screw fails to lift water due to the pocket boundaries overflowing back into lower tiers.
Calculate the volumetric flow rate by tracking how many revolutions it takes to fill the upper catch basin to a 100 mL mark.
Frequently Asked Questions (FAQs)
Q1: How does an Archimedes' Screw lift water against gravity?
The Archimedes' Screw turns a vertical lifting task into a continuous series of gentle ramps (inclined planes) wrapped around a central shaft. As the screw rotates, it creates moving pockets of air and water. Each pocket moves up the line because the bottom of each turn moves upward relative to the liquid inside it, pushing the liquid along until it discharges at the top.
Q2: What is the ideal angle of operation for this model?
For maximum efficiency, the angle of inclination of the main axis must be lower than the pitch angle of the internal screw blades. Generally, an operating angle between and yields the highest volumetric output in this lab kit.
Q3: Are Archimedes' Screws still used in the real world?
Absolutely. While ancient civilizations used them primarily for crop irrigation and draining bilge water from ships, modern engineers use giant Archimedes' screws for wastewater treatment plants, lifting fish safely over dams, and running reverse-hydroelectric plants to generate clean energy from flowing water.
Q4: How should the apparatus be maintained?
After working with liquids, always run clean, fresh water through the tube to wash out any residual dyes. Dry the components completely before storage to prevent water spots and biofilm formation inside the clear acrylic chamber
