Give 2 examples of where this “Wasted” energy went from the sand/bottle experiment AND EXPLAIN.

51. # 1 What are the 6 types of energy? Give me an example of each to show you understand each one……if details are needed, be sure you include them!!!!!

52. # 1 Answer See Foldable and/or J# 16 on www.mrs-twedt.com www.mrs-twedt.com

53. # 1 Explain, using our experiment with Beakers A (big), B (medium), and C (small), why Goldilocks and the 3 bears is scientifically inaccurate.

54. # 1 Answer Explain, using our experiment with Beakers A (big), B (medium), and C (small), why Goldilocks and the 3 bears is scientifically inaccurate. Beaker A was the hottest…and remained the hottest (like Papa Bear’s bowl) because it was the largest amount of the substance, The heat (Thermal Energy) that it took in (it took in the most), transfers back into the atmosphere (cooling) over the longest amount of time….because it is the largest. Beaker C was the coolest. It was the smallest (like Baby Bear’s bowl), so therefore it loses its heat the fastest. This contradicts the story where Baby Bear’s is just right. Beaker B was in the middle of the two temperatures because it is in the middle in size as well. This contradicts the story where Mama Bear’s is too cold. This is not possible. The smallest amount of mass will always cool the fastest because it contains the LEAST amount of matter AND therefore, the least amount of energy. –Think Hot Cocoa Pot vs. small mug
