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. Spiral disk with several long arms.






2. 1. State the problem. 2. Form a hypothesis. 3. Observe and experiment. 4. Interpret the data. 5. Draw conclusions.






3. An atom that has a different number of neutrons than its normal amount.






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






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

8. 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.






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






10. Occurs when heat is transferred due to fast moving atoms and molecules colliding with slower ones in a neighboring region.

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






17. Are huge clusters of billions of stars






18. Matter and energy have the properties of both particles and waves






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






20. Stored energy






21. Is the smallest unit of an element that still has the properties of that element.






22. One member benefits - the other is unaffected.






23. The quantity of substance






24. When the Moon or the Sun are pulling at perpendicular angles we get less extreme tides.






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






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






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






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






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






30. Stores food and other materials needed by the cell






31. 1. mutualism 2. parasitism 3. commensalism






32. Plants response to light






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






34. Is a method of separating ions within a substance by passing electrical current through the substance






35. 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.






36. An object in motion stays in motion along a straight path unless acted upon by a net external force.






37. 1. temperature (think movement) 2. pressure






38. 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.






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






40. 1. convergent 2. divergent 3. transform






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

45. Protects and supports the cell






46. 1. solid 2. liquid 3. gas






47. 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.
