Stuff you learn in school
At what temperature does water boil?
100oC
Plants perform this reaction to obtain its food.
Photosynthesis
You put a flaming match in carbon dioxide. What happens next?
The flame goes out
What causes a ball to accelerate down a hill?
Gravity
A trend of weather over a long period of time is called:
Climate
What organ digests food?
The stomach
Any living thing is called:
an organism
Name the first element of the periodic table.
Hydrogen
Einstein stated that light rays can be bent from gravity, which leads to gravitational lensing. This theory is called:
Theory of General Relativity
Which type of clouds bring rain, but no storms?
Stratus
What is a biotic factor?
Something that is living or was at once living
Name the chemical equation for photosynthesis. (in words)
water + carbon dioxide --> glucose + oxygen
A student accidentally drank dihydrogen monoxide. What should he do?
Nothing. It's just water.
What is the difference between speed and velocity?
Speed is distance over time, while velocity is displacement over time. Displacement is the shortest distance between two points.
You take a bottle of water out of the freezer. The bottle isn't leaking, but there is still water outside of the bottle. Why?
The cold temperature condenses the water molecules in the air.
When the temperature gets too hot, corals die in a process called:
bleaching
Water may evaporate from a plant's leaves. This process is called:
Evapotranspiration
B, C, N, O, ? - Fill in the missing letter.
F (these are elements 5, 6, 7, 8, and 9 respectively on the periodic table).
Galaxies appear redder when they move away from us. Similarily, a car's horn seems to decrease in pitch as it moves away from us. This is called the:
Doppler Effect
Magnesium metal reacts with hydrochloric acid to form magnesium chloride and hydrogen gas. What kind of reaction is this?
Single displacement
Name all steps of the scientific method.
Ask a question.
Form a hypothesis.
Perform an experiment.
Record observations.
Analyze data.
Draw a conclusion.
Traits inherited from dominant or recessive genes are called:
alleles
What is the Bronsted-Lowry Theory?
An acid will donate a proton in water, while a base would receive protons in water.
Imagine that you are in a free-falling elevator. You decide to jump right before it hits the ground so you will remain unaffected when the elevator hits the ground. Does this strategy actually work? Explain.
No, because you are falling with the elevator. If you somehow managed to jump, it would just lower your speed by a little bit before you accelerate back to the speed at which you are falling at.
Helium gas does not combine to form He2 molecules, but they sometimes still attract each other. This is due to:
London dispersion forces
