Icy Hot Lab
Phase Changes of Matter
(Physical Science)
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)
• Solid
• Close together
• Motion= vibrate
• Liquid
• Spread apart enough to slide
• Motion= flow in one direction
• Vapor (gas)
• Very spread out
• Motion= chaotic, going everywhere
Purpose
To determine the graphical relationship between
time (min) and temperature (°C) for water.
Prediction
-What will happen to the temperature as the
water is heated?
Draw a prediction of how your graph will
look, include labels and units.

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

(# all the way to 25min)
Temperature Observations

(°C)
Conclusion questions
• Sketch the graph from Logger Pro, connect the
dots.
