  1. Icy Hot Lab Phase Changes of Matter (Physical Science)

  2. Pre Lab Discussion • The arrangement of atoms in the three states of matter are drawn as particle diagrams. • The 3 parts of particle diagrams represent 3 of our vocabulary words • n (the number of particles)= mass (g) • The box= volume (mL) • Arrows (vectors)= temperature (C)

  3. Solid • Close together • Motion= vibrate

  4. Liquid • Spread apart enough to slide • Motion= flow in one direction

  5. Vapor (gas) • Very spread out • Motion= chaotic, going everywhere

  6. Purpose To determine the graphical relationship between time (min) and temperature (°C) for water. -What will happen to the temperature as the water is heated? Drawa prediction of how your graph will look, include labels and units. Prediction

  7. Materials (designate jobs for each group member) • Ice • Beaker • Thermometer probe (or alcohol thermometer) • LabQuest(LoggerPro3 software) • Ring stand • Clamp • Hot plate (or Bunsen burner) • Stirring rod

  8. Data • Create a data table that has enough rows to write 50 time trials and 3 columns (probably will need 2 pages)

  9. Conclusion questions • Sketch the graph from Logger Pro, connect the dots. Heating Curve
