In this experiment, we explored how electric potential changes with distance from a point electrode in water, mapping equipotential lines to reveal the geometry of the electric field.

This experiment builds a small thermoelectric generator using a Peltier module to show how temperature differences can be converted into electricity, highlighting the Seebeck effect, performance limits, and applications from waste heat recovery to space exploration.

This experiment investigates how temperature affects the activity of amylase in breaking down starch, showing that enzyme efficiency peaks at 40℃ and decreases at lower or higher temperatures due to reduced molecular motion or denaturation.

This experiment investigates how different pH levels affect the activity of catalase in yeast by observing the movement of yeast beads in hydrogen peroxide. By tracking bead motion as oxygen is released, students can visualize enzyme activity and better understand how pH influences biochemical reactions.

This experiment explores how different body positions—standing, sitting, lying down, kneeling, and standing on one leg—affect systolic blood pressure recovery after exercise, revealing how posture influences cardiovascular homeostasis.
