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. temperature (think movement) 2. pressure






2. Illustrates the relationship between absolute magnitude - luminosity - classification and effective temperature of stars.






3. 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.






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






5. That space and time are relative - not absolute concepts






6. Is a substance composed of two or more elements






7. Describes speed and direction






8. Protects and supports the cell






9. 1. producer 2. primary consumer 3. secondary consumer 4. tertiary consumer 5. decomposer






10. This is the motion of objects emitting or reflecting sound waves changing their frequency.






11. 1. the more massive either or both bodies are - the greater the gravitational force between them. 2. the further apart two bodies are - the lesser the gravitational force between them.






12. Energy changes forms but is not created or destroyed.






13. Is something that starts a chemical reaction - such as a spark.






14. Thin - flexible barrier around a cell; regulates what enters and leaves the cell






15. Plants response to light






16. Stored energy






17. Is an object's rate of motion = Distance/Time






18. One member benefits - the other is unaffected.






19. A group which resembles the experimental group in all other ways - but on which the hypothesis is not tested. In some clinical trials the control group is given a placebo.






20. A bond in which on atom loses an electron to form a positive ion and the other gains an electron to form a negative ion - creating an electrostatic force which holds them together.






21. The Moon and the Sun are on opposite sides of the Earth.






22. Energy in motion






23. The time required by half the atoms of a particular substance to disintegrate






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






25. Occurs when heat is transmitted in the form of electromagnetic waves.






26. Angiosperms






27. For every action there is an equal and opposite reaction.






28. Calories

32. Begin as huge clouds of dust and other particles called nebulas.






33. Phase where spindle grows and which cuts the cell






34. The quantity of substance






35. 1. gravity 2. magnetism 3. friction (think of a falling sheet of paper vs. a falling book)






36. 1. puzzle piece argument 2. sea floor spreading 3. fossil records






37. The types of organisms an ecosystem can support is primarily determined by the amount of...






38. Control center of the cell






39. Are caused by the gravitational pull of the Moon and the Sun on the Earth.






40. Is a substance that cannot be separated into simpler substances by chemical means






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






42. A group of subjects upon which a hypothesis is tested.






43. 1. homeostasis 2. organization 3. metabolism 4. growth 5. adaptation 6. response to stimuli 7. reproduction






44. An ion






45. That matter cannot be created or destroyed; it simply changes form.






46. 1. inner core 2. outer core 3. mantle 4. crust






47. 1. hair 2. warm - blooded 3. live birth 4. nurses their young
