•Chlorine is a gas located in group 17 on the periodic table. It is so unstable and reactive, that it can only exist as a molecule in pairs (Cl2) or in compounds with other elements (like NaCl – salt). Fluorine and bromine are also in group 17 on the periodic table. What would you predict to be the properties of fluorine and bromine to be?
A.They would be non-reactive solids
B.They would both be highly reactive gases that exist only in pairs or in compounds
C.Fluorine would be a highly reactive gas, but bromine would be a stable solid
D.It is impossible to tell based on this information
B: They would both be highly reactive gases that exist only in pairs or in compounds

•Giselle decided to observe the birds that came to her yard at the same time everyday for a week. After two days, she decided to put a bird bath in her yard. Her observations are shown in the table. What is the best inference about bird behavior that she can make based on her observations?
A.The presence of a bird bath had no affect on the number of birds in her yard.
B.The increasing numbers of birds AFTER the addition of the bird bath indicates that birds have a learned trait (behavior) to seek out water.
C.Birds have a natural dislike of water and prefer very dry areas
D.Birds would have preferred having a bird feeder rather than a bird bath
B.The increasing numbers of birds AFTER the addition of the bird bath indicates that birds have a learned trait (behavior) to seek out water.

•We are doing an experiment to see how changing the ramp height affects the distance that a toy car can travel. We will be using 2 ramp heights, letting the car travel down the ramp, then measuring how far it went. The procedure says to do 5 replicates (repeat the trial) 5 times for each ramp height.
Why do we need to do so many replicates?
A.It is clearly a misprint and we only need to do it once for each ramp height
B.Lots of things are changing at the same time, so we need to do it many times to account for all the variables
C.We are supposed to use 5 different cars at each ramp height so we need to do it 5 times each
D.Doing multiple replicates allows us to find an average value for the data, which will give us more information than just one observation at each height
D: Doing multiple replicates allows us to find an average value for the data, which will give us more information than just one observation at each height
