- 46. A disturbance that transfers energy from place to place
- 47. The transfer of energy by electromagnetic waves.
- 48. A measure of the average kinetic energy of the particles in an object.
- 49. The Factors that are intentionally kept the same in an experiment . The scientist makes sure they do not change.
- 50. Scientific information acquired by observation or experimentation.
- 51. A material that does not transfer thermal energy easily - it resists the gain or loss of temperature.
- 52. The transfer of thermal energy by the circulation or movement of a liquid or gas.
- 53. Using your 5 senses to recognize the environment around you.
- 54. An observation made by counting or by using tools like thermometers or rulers that result in numerical data.
- 55. A fake or false science that makes claims based on little or no scientific evidence.
