Answer 1

Matching
For questions 22–31, Place the letter of the term that best matches the situation.

Terms:
A. Variables
B. Analysis
C. Experimental group (warmer or colder than body temperature)
D. Conclusion
E. Data collected
F. Controlled conditions
G. Preliminary observation
H. Control (closest to body temperature)
I. Hypothesis
J. Question

22. Materials feel warm or cool to the touch
23. Wood
24. Metal, Styrofoam
25. Will different surfaces affect the melting rate of an ice cube?
26. Different counter surfaces
27. If an ice cube is placed on the surface of each material, then the material that feels warmest will melt the ice cube the fastest.
28. Measurement of melting time
29. The material that felt the coolest melted the ice the fastest.
30. Same sized ice cubes, flat surfaced materials and equal mass
31. The materials tested were at room temperature. Since body temperature was warmer than the room temperature, heat will be lost to the material in direct relationship to its density. Styrofoam, as the least dense, felt closer to body temperature and didn't lose much heat. However, it was the best insulator and maintained the ice cube the longest.
