Matter's Fingerprints

βš–οΈ We have a mystery piece of metal! Weigh its mass on a scale and measure its volume in water to find its density, then check the table to discover what it is. Interestingly, a piece twice as large has the exact same density because density depends on the material, not the amount! 🌑️ Boiling points work the same way. Doubling the amount doubles the boiling time, but the boiling temperature stays at 78Β°C. Higher heat only makes it boil faster without changing the temperature. πŸ“‹ Finally, let's read the table! Knowing melting and boiling points tells us whether a substance is solid, liquid, or gas at any temperature. At -50Β°C, ethanol is liquid while water is frozen solid. Made with code β€” remix it to add your own substances!

About this app

This interactive educational tool helps middle school students explore physical properties that identify substances, known as chemical fingerprints. Users can measure density using virtual scales and water displacement, observe boiling points under different volume and flame conditions, and inspect states of matter across various temperatures. The app demonstrates that intrinsic properties like density and boiling point remain constant regardless of sample size or heating power.

Use cases

  • Middle school students studying physical properties and characteristic traits of matter
  • Science teachers looking for interactive lab simulations on density and phase changes
  • Self-learners practicing how to determine states of matter using melting and boiling point tables

Features

  • Virtual balance and water displacement tools to calculate density from mass and volume
  • Interactive heating simulation to test how sample volume and flame intensity affect boiling points
  • State-of-matter table exploring solids, liquids, and gases at custom temperatures
  • Step-by-step guided problem scenarios with immediate feedback
  • Sound effects and multilingual interface options
