Laboratornye Po Fizike 8 Klass Korshak Savchenko Liashenko Page

Alex’s year began with Thermal Phenomena . In the first lab, he carefully measured the cooling of water over time, plotting a graph that looked like a gentle slide. Later, he used a calorimeter to find the specific heat capacity of a metal cylinder. He dropped the hot metal into cool water, watching the thermometer climb as the two reached "thermal equilibrium"—the perfect balance of energy exchange.

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. Key Lab Topics covered in the Korshak textbook: Alex’s year began with Thermal Phenomena

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. He dropped the hot metal into cool water,
