What are the AAAS Benchmarks?
Project 2061 has a set of science content benchmarks that are
generally aligned with the AAAS National Science Ed. Standards.

Where can I find information on what type of graph to use when?
You might look in the 6th and 7th grade math books. You should
know that, in general, to show change over time, you want a line
plot, with time on the horizontal (X) axis.) A bar graph is used to
compare quantities. The key thing with the graphs is that you
know what a complete graph looks like, so you can spot errors in
the ones they may show you. For example, are both the axes
clearly labelled, with units and what the units are showing (eg,
"volume of liquid, in ml"). Does the graph have a title? Is there a
key? Can you tell which line or bar is which? Are the axes
marked off in regular increments (2, 4, 6, 8) or has the student
simply put his data points onto the axis? If it is a line graph are
the points connected?
