⚗️ Chemical Reactions Lab
Add chemicals to the beaker and observe reactions! Learn about acids, bases, indicators and gas evolution.
🌡️ Temperature: 25°C
Add chemicals to begin an experiment!
Did you know? The pH scale goes from 0 (very acidic) to 14 (very alkaline). pH 7 is neutral (pure water). Litmus turns red in acid and blue in base — just like magic!
🔭 Pendulum Simulation
Adjust length, mass and gravity to see how a pendulum behaves. Verify Galileo's discovery that period depends only on length!
Formula: T = 2π√(L/g) — Period depends only on length (L) and gravity (g), not mass! This was discovered by Galileo Galilei around 1602.
🧪 pH Meter Simulator
Test common substances and learn where they fall on the pH scale!
Select a substance to test!
Remember: 0–6 = Acidic (sour/reactive), 7 = Neutral (pure water), 8–14 = Alkaline/Basic (soapy). Your stomach has pH ~1.5 to help digest food!
⚡ Ohm's Law Explorer
Adjust voltage and resistance to see how current changes. V = IR is Ohm's Law!
Ohm's Law: V = I × R → I = V/R V = Voltage (Volts), I = Current (Amperes), R = Resistance (Ohms) Doubling voltage doubles current. Doubling resistance halves current.
