2. Negatively charged particle with extremely small mass found in the space around the nucleus of atoms.

3. What are electrons?

4. The subatomic particles that have a positive electrical charge and are found in the nucleus.

5. What are protons?

6. A neutral subatomic particle in an atom’s nucleus that has a mass nearly equal to that of a proton.

7. What is a neutron?

8. Division of an atom’s nucleus into two or more fragments resulting in a release of neutrons and energy.

9. What is fission?

10. The process in which atomic nuclei with small masses are combined to form a nucleus with a larger mass.

11. What is fission?

12. It includes gamma rays, X-rays, ultra-violet, visible light and microwaves.

13. What is electromagnetic radiation?

14. It is a way to estimate the age of a fossil based on the remaining amount of Carbon-14

15. What is Carbon Dating?

16. It is caused by the natural heating of Earth’s surface by certain atmospheric gases which helps keep Earth warm enough to sustain life.

17. What is the greenhouse effect?

18. It is a geological explanation for the movement of continents over Earth’s thick, liquid interior

19. What is plate tectonics?

20. It is the ancient landmass made up of all the continents that began to break apart about 200 million years ago.

21. What is Pangea?

22. It is the central membrane- bound organelle that manages cellular functions and contains DNA

23. What is the nucleus?

24. They are organelles containing chlorophyll that capture energy from the sun to convert carbon dioxide and water into simple sugars.

25. What are chloroplasts?

26. The process by which autotrophs such as algae and plants trap energy from sunlight.

27. What is photosynthesis?

28. They are the cell structures in the nucleus that carry the genetic material that is copied and passed on from generation to generation.

29. What are chromosomes?

30. Organelles in eukaryotic cells that transform energy stored in food molecules into ATP.

31. What are mitochondria?

32. The leading theory about the formation of the universe which states that the universe was created about 15 billion years ago after a huge explosion.

33. What is the Big Bang Theory?

34. It is a massive group of stars, gas, and dust held together in space by gravity. Ours is the Milky Way.

35. What is a galaxy?

36. It is a rocky remnant of the early solar system found mostly between the orbits of Mars and Jupiter.

37. What is an asteroid?

38. It produces a streak of light when a meteroid falls toward Earth and burns up in Earth’s atmosphere.

39. What is a meteor?

40. A meteroid that does not completely burn up in Earth’s atmosphere and strikes Earth’s surface, sometimes causing an impact crater.

41. What is a meteorite?

42. The energy of an object due to its motion.

43. What is kinetic energy?

44. It is stored energy resulting from the position of an object.

45. What is potential energy?

46. It is the force of attraction for all objects that depends on their masses and the distance between them.

47. What is gravity?

48. It is a complex macromolecule such as RNA or DNA that stores genetic information in cells in the form of a code.

49. What is Nucleic Acid?

50. A structure, behavior, or internal process that enables an organism to respond to stimuli and better survive in an environment.

51. What is an adaptation?
