When the National Academy of Sciences published a guide on teaching evolution last month, it was no accident, then, that it also focused on what teachers should know and explain to students about the nature of science.	If an accident happens during a science experiment, the first thing a student should do is report to the teacher.	neutral	an accident<>happens<>during a science experiment$$$the first thing<>should do<>a student$$$the first thing a student should do<>is<>report to the teacher

Latent heat flux is the energy removed from or delivered to the snowpack which accompanies the mass transfers of evaporation, sublimation, or condensation.

When the jet stream dips to the south in the Northern Hemisphere, it creates a trough of low pressure, allowing cold polar air masses to invade the United States.	The best explanation for how air masses move across the united states is that the prevailing westerlies move air masses from west to east across the united states but may be deflected by the jet stream.	neutral	air masses<>move<>across the united states$$$the prevailing westerlies<>may be deflected<>by the jet stream$$$The best explanation for how air masses move across the united states<>is<>that the prevailing westerlies move air masses from west to east across the united states but may be deflected by the jet stream$$$the prevailing westerlies<>move<>air masses<>from west<>to east<>across the united states
