# 3 A ball was launched 4 times from 3 different thicknesses rubber bands. The distance the ball traveled was measured each time. The average of the trials are shown. What is the Test Variable? What is the Outcome Variable? Rubber band launching balls Thickness of Rubber band Avg of 4 trials (avg. distance traveled in cm) Thin75 Medium94 Thick113

# 3 Answer A ball was launched 4 times from 3 different thicknesses rubber bands. The distance the ball traveled was measured each time. The averages for the trials are shown. What is the Test Variable? THICKNESS OF RB What is the Outcome Variable? DISTANCE TRAVELED Rubber band launching balls Thickness of Rubber band Avg. of 4 trials (avg. distance traveled in cm) Thin75 Medium94 Thick113

# 4 Which would be a good conclusion for the data and why? Also tell me why NOT the other two. a.The thick rubber band worked the best because it could get the best grip on the ball. b.My purpose is to see if the thickness of a rubber band (RB) is related to how far a ball can launch from that elastic interaction. I thought that if the thickness of the RB was increased, then the distance the ball would travel would increase. This was supported because as you can see, with the thickest RB, the ball traveled an average of 113 cm. This confirms the relationship between the thickness of the RB and the distance traveled. c.My purpose is to see if the thickness of a rubber band (RB) is related to how far a ball can launch from that elastic interaction. I thought that if the thickness of the RB was increased, then the distance the ball would travel would increase because the elastic interaction would act as a force propelling the ball. This was supported because as you can see, with the thickest RB, the ball traveled an average of 113 cm. With the Medium RB, it only traveled an average 94 cm, and with the Thin RB, the ball only traveled an average of 75 cm. This confirms the relationship between the thickness of the RB and the distance traveled.

# 4 Answer Which would be a good conclusion for the data and why? Also tell me why NOT the other two. a.Opinion b.Hypothesis doesn’t have a BECAUSE and it doesn’t Contain ALL data. c.Has a purpose, restated hypothesis (that is correctly written), says it was supported and includes data for ALL trials, and the relationship is addressed. It is also NOT an opinion.

# 5 What do all 6 types of Energy have in common?

# 5 Answer What do all 6 types of Energy have in common? They all can be transformed into each other AND all 6 Cannot be created NOR Destroyed (Law of Conservation of Energy…..KNOW THIS!!!)

# 6 The law of conservation of energy also states that when energy is transforms/converted, the amount of “useful” energy decreases in the process. Give 2 examples of where this “Wasted” energy went from the sand/bottle experiment. EXPLAIN

# 6 Answer The law of conservation of energy also states that when energy is transforms/converted, the amount of “useful” energy decreases in the process. Give 2 examples of where this “Wasted” energy went from the sand/bottle experiment AND EXPLAIN. Energy went to: The bottle (absorbed the Thermal from the sand AND from you) The air (the shaking caused vibrations which transformed into sound) Back to you (also Thermal from the sand and bottle)

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

# 1 Answer Explain, using our experiment with Beakers A (big), B (medium), and C (small), why Goldilocks and the 3 bears is scientifically inaccurate. The temperature of the beakers (average kinetic energy in the molecules) SHOULD have been the same at the start! Beaker A was the hottest…and remained the hottest (like Papa Bear’s bowl) because it was the largest amount of the substance, therefore the most amount of Thermal Energy (total kinetic energy)….so it had the most to lose. Heat was transferred out of this beaker the slowest. 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 when looking at the amount of heat transferred out of the beaker. This is because it is in the middle in size (amt of matter) 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 Tea Pot vs. small mug *Know Thermal vs. Temperature vs. Heat!!!
