5 New Experiments Add to PraxiLabs Library

PraxiLabs library has grown again this term, with five new experiments now ready to use across three physics, biology, and chemistry. Each addition is built to fit directly into an existing course, giving instructors another way to cover core concepts hands-on, without needing extra lab time, equipment, or budget.

Physics: Electricity and Mechanics

• Parallel Plate Capacitor: Students adjust plate separation, plate area, voltage, and dielectric material to see how each factor changes capacitance and charge storage, linking the numbers directly back to Gauss’s Law.
• Equipotential and Field Mapper: An interactive way to plot equipotential lines around different charge setups, helping students build intuition for how electric fields behave near conductors.
• Projectile Motion: Students calculate initial velocity two different ways, reinforcing how horizontal and vertical motion combine to shape a projectile’s path.

Biology: Lab Foundation

• Introduction to Microscopes: A guided walkthrough of microscope types, correct handling of a compound light microscope, wet mount slide prep, and observing cheek cells at different magnifications, including immersion oil technique for high-power viewing.

Chemistry: Electrochemistry

• Standard Electrode Potential of Silver: Students build a galvanic cell with a standard calomel reference electrode, measure the cell potential, and work out the standard electrode potential of silver, turning a topic often left to theory into a measurable result.
