Longitudinal waves move through different materials at different rates. Their rate depends partly on whether the material is in a liquid, solid, or gaseous state. Certain states of matter allow longitudinal waves to pass through more quickly than others.
List the states of matter according to their wave transmission rates, from slowest to fastest? **Think about what longitudinal waves travel through…

List the states of matter according to their wave transmission rates, from slowest to fastest? This is SOUND! *a medium is needed…where is the medium closest together, so easiest to transfer energy?

Why is it that when watching something, like a baseball game, you can see the batter hit the ball before you actually hear the crack of the bat?
Because light travels faster than sound! You SEEING something is visible electromagnetic energy!

# 3 Answer A ball was launched 4
times from 3 different sized rubber bands. The distance the ball traveled was measured each time. The best values of each trial are shown.
What is the Test Variable? WIDTH OF RB What is the Outcome Variable? DISTANCE TRAVELED
Rubber band launching balls
Width of Rubber band
B.V. of 4 trials (avg. distance traveled in cm)
Thin 75
Medium 94
Thick 113
# 4Which 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. The Thick rubber band allowed the ball to travel the
farthest. As you can see, with it, the ball traveled 113 cm. With the Medium RB, it didn’t travel far.
c. The Thick rubber band allowed the ball to travel the farthest. As you can see, with it, 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.
# 4 AnswerWhich 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. Opinionb. The Thick rubber band allowed the ball to travel the
farthest. As you can see, with it, the ball traveled 113 cm. With the Medium RB, it didn’t travel far. Doesn’t Contain ALL data.
c. The Thick rubber band allowed the ball to travel the farthest. As you can see, with it, 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. CONTAINS ALL DATA AND IS NOT AN OPINION.

# 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)

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