Physical Science Study Guide for Trimester One Final
1. Name the three types of graphs most commonly used in science. In which situation do you use each one?
2. What makes up the building blocks of all matter?
3. What are the steps of the scientific method? Describe what happens in each one.
4. What are the most important lab safety procedures?
5. How do you convert numbers into scientific notation?
6. Convert measures from one unit to another (kilo, hecto, deka, ___, deci, centi, milli).
7. What is the difference between being precise and being accurate?
8. Demonstrate a relationship between a manipulative variable and a responding variable on a graph.
9. How are scientists who speak different languages able to communicate with each other?
10. What is a pure substance? Examples?
11. What are substances called that are made up of only one type of atom?
12. What is a material containing elements in a fixed proportion is called?
13. What is the difference between homogeneous mixtures and heterogeneous mixtures? Identify some examples of each.
14. What is the difference between the mixtures classified as solutions, suspensions or colloids?
15. Which substance has a melting point of 0ºC and a boiling point of 100ºC?
16. What are the five properties of metals (multiple chapters)?
17. Describe how force being exerted over difference surface areas changes.
18. Define the terms temperature, pressure, volume, and mass and describe how they affect each other.
19. Describe the different phase changes: sublimation, deposition, vaporization, sublimation, and melting.
20. What is the difference between endothermic change and exothermic change (multiple chapters)?
21. What are the charges of each subatomic particle (protons, neutrons and electrons)?
22. Define the terms atomic number and atomic mass and discuss them in detail. Be sure to connect what you know to patterns in the periodic table.
23. Explain what an isotope of an element is and how it related to an elements atomic mass number.
24. Explain why we frequently use Bohr’s model (how it’s structured).
25. Explain what Mendeleev contributed to chemistry and how he arranged the elements (different from how the table is arranged today).
26. Explain the basic patterns in the periodic table (periods versus groups).
27. Which elements are the most reactive (think in terms of two groups, not one)?
28. Discuss valence electrons in detail (what are they, how do they behave, and how do they relate to the periodic table).
29. Describe ionic bonding and identify ionic bonds.
30. Define covalent bonding (molecular bonding) and explain the function of polar and nonpolar covalent bonds .
31. How is bonding related to chemical reactions?
32. What is the difference between chemical reactants and products, and how are they are involved in synthesis, decomposition and replacement?
33. What is the difference between subscripts and coefficients (know what they “do to” atoms not just what they are)?
34. What do the prefixes “di” and “tri” indicate in molecules?
35. What are alloys and how are their properties different from that of metals?
36. Give examples of chemical equation that are balanced.
37. What affects reaction rates?
38. Which three things are needed to maintain a fire and what happens without just one of them?
