CSET Subject 2: Science

Subjects : cset, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. 1. neutral charge 2. located in the nucleus 3. mass is 1 AMU






2. An isotope created in the earth's atmosphere by cosmic rays. All living things absorb carbon 14. When they die absorption stops and the organism's existing C14 begins to radioactively decay back to C12.






3. Caused by the Earth's tilt on its axis. As it revolves arond the Sun - the tilt causes each hemisphere to receive more direct exposure at certain times in its orbit.






4. A material that can be separated by physical means into two or more substances.






5. Occurs when light returns after bouncing off an object.






6. Both members of a symbiotic relationship benefit

11. Occurs when light is bent while passing from one medium into another.






12. One member benefits - the other is unaffected.






13. Calories






14. A bond formed when atoms share one or more of their valence electrons.






15. The number of protons a particular type of atom has. The atomic number defines the type of element.

31. 1. by row 2. atomic number and mass increase as you move left to right and top to bottom






32. Subatomic particles including: 1. protons 2. neutrons 3. electrons






33. Is the particular wavelength of light we observe that is not absorbed by an object.






34. When the Moon and the Sun are in alignment we get more extreme tides.






35. Protects and supports the cell

42. States that all of the Earth's continents at one time were joined as a single 'super - continent' called Pangaea. Over time - the continents drifted apart.






43. The measure of the kinetic energy in a substance's molecules. Simply - temperature is atomic motion.
