Final Jeopardy
2
1 - 100

• What is the Law of Conservation of Energy?

• Energy can neither be created nor destroyed (it
  can only be transferred or transformed).

3
1 - 200

• Explain what happens when you open the door to a
  freezer or refrigerator.

• Thermal energy from outside is transferred to the
  inside of the refrigerator, raising the internal
  temperature.

4
1 - 300

• Define kinetic energy. Give 3 types of kinetic
  energy and an example of each.

• Kinetic energy is energy of motion.Motion,
  sound, light, thermal, electric current

5
1 - 400

• Define potential energy. Give 3 different types
  of potential energy and an example of each.

• Potential energy is stored energy.Chemical,
  elastic, electric static, nuclear, gravitational

6
1 - 500

• List the 6 simple machines and give an example of
  each.

• Lever inclined planeWedge pulleyScrew whee
  l and axle

7
2 - 100

• What is the acceleration of an object
  experiencing balanced forces? (need units!)

• 0 m/s2

8
2 - 200

• An object travels 65 m in 5 seconds. What is its
  speed?

• Speed distance/timespeed 65 m/ 5s ? 13
  m/s

9

• What are Newtons 3 laws of motion?

• 1 inertia2 Fma3 action-reaction pairs

10
2 - 400

• Kevin pushes Bill on a swing with 200 N of force.
  Bill moves 5 m. How much work did Kevin do?

• W Fdw 1,000 J

11
2 - 500

• What is the efficiency of a hammer that does 15 J
  of work on a nail after I apply 30 J of work?
  Why is efficiency never 100?

• Efficiency (output work/input work) x
  100Efficiency 50Efficiency is never 100
  due to friction.

12
3 - 100

• What causes seasons? What causes day and night?
  What causes a year?

• Earths tiltEarths rotationEarths revolution

13
3 - 200

• What is the relationship between mass, distance,
  and gravity? Be specific.

• More mass more gravityMore distance less
  gravity

14
3 - 300

• Outside the solar system, is there gravitational
  pull from the Sun? Explain.

• Yes. Gravity never disappears, it just gets very
  very small as you increase distance.

15
3 - 400

• What is a solstice and an equinox?

• Summer solstice is longest day of the year,
  winter solstice is shortest. Fall and spring
  equinoxes each have about 12h/12h day/night. June
  21, Dec. 21. Sept. 21, March 21

16
3 - 500

• Explain how your shadow would change over the
  course of a day (from sunrise to sunset) and WHY
  this happens.

• From sunrise until about noon, your shadow is
  gradually getting smaller because the appears to
  move from east to west across the sky, caused by
  earths rotation creating a larger solar angle.
  The sun is highest around noon. From noon to
  sunset, your shadow gradually gets larger as the
  sun sets in the west, creating a smaller solar
  angle.

17
4 - 100

• Bioengineers often design prototypes. Define
  BOTH bioengineer AND prototype.

• Bioengineers use science, technology and math in
  order to solve everyday/medical problems.A
  prototype is the first model of a product.

18
4 - 200

• Give 3 possible causes for the extinction of a
  species.

• Over-predation/hunting, invasive species, loss of
  habitat, loss of food sources, disease,
  catastrophic events, human activity leading to
  pollution

19
4 - 300

• List 3 pieces of evidence that support evolution.

• DNA, fossil/skeleton records, and similarities in
  physical traits

20
4 - 400

• What are 3 trade-offs to bringing back an extinct
  species?

• Cost, time, potential to spread diseases, may
  interrupt food chain/ecosystem

21
4 - 500

• Explain how a mutation can lead to evolution of
  an entire species.

• If mutation is favorable, it will be passed on
  through generations. Natural selection says that
  organisms with traits making them more fit to an
  environment will survive long enough to reproduce
  and pass on those traits to their offspring.

22
5 - 100

• What are the units for force, work, and power?

• Newtons, Joules, Watts

23
5 - 200

• Joey wants to know how music affects plant
  growth. He exposes 3 identical plants to either
  rap, classical, or rock music for 2 weeks and
  measures their growth. What control can Joey use?

• Joey can get another plant and expose it to no
  music for 2 weeks.

24
5 - 300

• Joey wants to know how music affects plant
  growth. He exposes 3 identical plants to either
  rap, classical, or rock music for 2 weeks and
  measures their growth. What are the IV and DV in
  his experiment?

• IV music type DV plant height

25
5 - 400

• Joey wants to know how music affects plant
  growth. He exposes 3 identical plants to either
  rap, classical, or rock music for 2 weeks and
  measures their growth. What is a possible
  hypothesis for Joeys experiment?

• If a plant is exposed to classical music then it
  will have the most growth because classical music
  promotes plant growth.

26
5 - 500

• What is the difference between qualitative and
  quantitative observations? Give one qualitative
  and one quantitative observation about your shoe.

• Qualitative descriptions Quantitative
  numbers/measurementMy shoe is black.My shoe is
  a size 9.5.
