The year ended with Light Phenomena . alex darkened the room to study reflection and refraction . Using a glass prism and a ray box, he watched light bend as it entered the glass—the same principle that makes a straw look broken in a glass of water. For his final lab, he measured the focal length of a lens , moving a screen until a candle flame suddenly snapped into sharp, upside-down focus.

Measuring current and voltage, and calculating the resistance of a conductor.

As the snow fell outside, the class moved to Electrical Phenomena . Alex felt like an engineer as he assembled his first circuit using a battery, a bulb, and a switch. He learned to use an Ammeter and a Voltmeter , realizing that current is like water flow while voltage is the pressure pushing it. He spent one afternoon proving Ohm's Law , adjusting a rheostat and watching the needle dance across the scale, confirming that as resistance goes up, the current fades.
