Use the G.U.E.S.S. method to answer the following question: What is the current produced by a voltage of 240 V through a resistance of 0.2 ohms?
G: V = 240V and R = 20ohms
U: I (Current) = ?
E: I = V/R
S: I = 240V / 0.2 ohms
S: I = 1200A
Therefore, the current is 1200A.
Draw a Solar Eclipse and Lunar Eclipse.
Solar Eclipse: Sun - Moon - Earth
Lunar Eclipse: Sun - Earth - Moon
What is the name of the type of watershed that has high levels of nutrients and low levels of oxygen?
(Extra 100 points if you are able to explain the process that led to this type of watershed)

Use the G.U.E.S.S. method to answer the following question: What is the percent efficiency of a motor that produces 4730 J of mechanical energy, while using 6520 J of electrical energy? (Round to the nearest whole percent).
G: Energy In = 6520J and Energy Out = 4730J
U: Percent Efficiency = ?
E: Percent Efficiency = Energy Out / Energy In x 100%
S: Percent Efficiency = 4730J / 6520J x 100%
S: Percent Efficiency = 73%
Therefore, the motor is 73% efficient.
Distinguish between the following celestial objects:
1) Planet vs. Dwarf Planet
2) Asteroid vs. Meteoroid vs. Comet
1) Planet - spherical, orbits the Sun, and dominates its orbit
Dwarf Planet - spherical, orbits the Sun, but DOES NOT dominate its orbit
2) Asteroid - piece of rock and metal, mostly in the Asteroid Belt
Meteoroid - piece of rock and metal (smaller than asteroid)
Comet - piece of rock and ice, orbits around the Sun
H.I.P.P.O refers to various threats to biodiversity. What does each stand for?
Habitat Loss, Invasive Species, Pollution, Population, Overexploitation
Which element is in Group 2, Period 3 on the Periodic Table?
How many Valence Electrons does this element have?
(Extra 100 points if you can tell me 1 physical property and 1 chemical property of this element)
Magnesium (Mg) - 2 valence electrons
Use the G.U.E.S.S. method to answer the following question: How much does it cost to operate a 4300 W cooker if it is used 1 hour each day for a week, and the cost of electricity is 5.7 cents/kW-h?
G: Power = 4300 W (4.3 kW)
Time = 1 hour each day for a week (7 hours)
Cost of Electricity = 5.7 cents/kW-h
U: Cost to Operate = ?
E: Cost to Operate = Power x Time x Cost of Electricity
S: Cost to Operate = 4.3kW x 7 hours x 5.7cents/kW-h
S: Cost to Operate = 171.57 cents = $1.72
Therefore, it would cost $1.72 to operate a 4300 W cooker if used 1 hour each day for a week.
