1. A tool used to observe very small objects and organisms Hand lens

2. Metric Ruler or Meter Stick A tool used to measure the length of an object or the distance an object may have traveled. Units = meters, centimeters, or millimeters

3. Microscope An instrument for observing objects too small to be seen with a hand lens

4. Thermometer A tool for measuring temperature Units = Celsius

5. Graduated Cylinder A tool for measuring the volume of liquid Units = milliliter (ml)

6. Beaker A tool for measuring the volume of liquid Units = milliliter (ml)

7. Goggles A tool for protecting eyes during a Science experiment

8. Apron An apron is used to protect your body and clothes during a Science experiment

9. Balance It is used to measure the mass of an object. Unit = Grams

10. Compass A tool that shows the direction that one is going

11. Magnet A tool that can attract metal, such as iron or steel

12. Hot plate A device used to heat up liquids or solutions in a Science classroom.

13. Timer A tool used to measure intervals of time. Units = seconds, minutes, or hours

14. Gloves These go on your hands to protect them when you are handling chemicals or touching hot objects.

15. Extinguisher Fire Tool used for putting out small fires

16. Hazard A source of danger

17. Precaution A measure taken beforehand to prevent harm

18. Tongs A tool used in Science to hold onto hot objects while they are heated.

19. Experiment A procedure carried out under controlled conditions in order to discover something or to test a hypothesis.

20. Hypothesis An educated guess about how an experiment will turn out. A hypothesis can be proven right or wrong through an experiment.

21. Data A collection of facts or numbers gathered during an experiment. Usually arranged in a chart or data table.

22. Graph A picture used to represent the data collected during an experiment. There are many types: • Pictographs • Bar graphs • Circle graphs • Line graphs This is a bar graph.

23. Scientific Model A visual representation of Science concepts All models have limitations, this means they are not 100% correct as the real concept they are representing.

24. Conclusion A closing statement based upon the data collected during an experiment. Usually the hypothesis is stated to see if it was right or wrong in the conclusion.

25. Experimental Trials Scientists repeat their experiments many times to make sure the results are valid and reliable.

26. Recycle Reprocessing of materials, such as, plastic, glass, metal, & paper so they can be reused.

27. Conservation The protection, preservation, and wise use of natural resources.

28. Matter Anything that takes up space (volume) and has mass.

29. Mass The measure of the amount of matter in an object. Units: • Grams • Milligrams • kilograms

30. Volume How much space something takes up

31. Solid Phase or State of matter that has a definite shape and a definite volume

32. Liquid Phase or State of matter that does NOT have a definite shape, but has a definite volume.

33. Gas Phase or State of matter that does not have a definite shape or a definite volume.

34. Melting Point The temperature at which a substance changes from its solid state into its liquid state.

35. Freezing Point The temperature at which a substance changes from a liquid to a solid.

36. Boiling Point The particular temperature when a substance changes from a liquid to a gas.

37. Evaporation A liquid changes phase into a gas. Opposite of Condensation.

38. Condensation A gas changes phases and turns into a liquid. Opposite of Evaporation.

39. Physical Properties Characteristics of matter that can be observed or measured without chemically changing the substance into something new. Examples: • Magnetism • Color • Density • Texture • Buoyancy

40. Conduction The passing of heat or electricity through a material while the material itself stays in place. Examples: • Steel • Iron

41. Insulation Material energy (heat or electricity) cannot easily pass through. Examples: • Plastic • Cloth • Rubber • Wood

42. Solution A mixture of substances that are blended so completely that the mixture looks the same everywhere. Example: Sugar water Sugar is dissolved in the water.

43. Dissolve The process of going into a solution. It becomes disintegrated.

44. Mixture A combination of two or more substances that can keep their own properties and can beseparated again

45. Electrical Energy Otherwise known as Electricity. Flowing of electrons through a circuit to produce a charge.

46. Open Circuit Contacts, switches or similar devices are not connected thus preventing the flow of electrical current.

47. Closed Circuit An electric circuit providing an uninterrupted, endless path for the flow of current.

48. Electromagnet Wire coil around a metal core (usually an iron nail) that acts like a magnet when an electric current flows through it

49. Solar Energy Energy from the Sun. Can be used to make electricity.

50. Light Energy A form of energy that travels in waves and can move through empty space where there is no air.
