Unit 1 Vocabulary

3. Scale – Y. A temperature scale where 0°C is the freezing point of water and 100°C is the boiling point.
5. – C. The force of gravity acting on an object's mass.
7. – O. A testable prediction or educated guess.
10. – M. Information gathered using the senses.
11. – D. The ability to do work or cause change.
14. – U. How close repeated measurements are to each other.
15. – T. How close a measured value is to the actual or true value.
16. – V. Mass per unit volume of a substance (e.g., g/cm³).
19. Error – R. Error that consistently skews results in the same direction; due to flawed equipment or procedure.
21. – B. The amount of matter in an object; does not change with location.

1. Method – L. A systematic approach used in scientific study involving observation, experimentation, and analysis.
2. – H. Something that has magnitude, size, or amount and can be measured.
4. Observation – J. Descriptions using characteristics but not numbers (e.g., color, smell).
6. – N. A logical interpretation based on prior knowledge and experience.
8. – W. A measure of the average kinetic energy of particles in a substance.
9. – Q. Collected measurements and observations used for analysis.
12. – P. A summary of what you have learned from an experiment.
13. Energy – F. Stored energy based on position or condition.
17. Scale – X. A temperature scale that starts at absolute zero (e.g., Kelvin).
18. Observation – K. Observations that include measurements or numbers.
20. Error – Z. The difference between a measured value and the accepted value, expressed as a percentage of the accepted value.
