I did a science fair project involving placing butterfly larvae in different rooms with different temperatures to see which ones developed faster. My hypothesis, which was proven, basically stated that the larvae in the warm room would grow faster than all the other groups. Now i have to make a null hypothesis....Would exactly would that say? Like...there will be no difference or something? Thanks...

In statistics, null hypothesis is basically the status quo. So the null hypothesis would be that the larvae grow at the same rate in the warmer room and in the control room.
Cool experiment, good luck with your science fair =]

Amy and Justcurious are correct, so award them 10 points. In a scientific experiment, your aim is to see if you can DISPROVE the null hypothesis. If the null hypothesis were true, what would you see? If you conclude that you disprove the null hypothesis, how different would your result have to be? It may be that you cannot disprove the null hypothesis if you find, "Hey! A lot of butterflies here! A lot more over there! Who knows?" Statistical analysis.

just say something to the effect that larvae in cooler climates tend to grow at the same pace as those in warmer climates. Based on your data you would have to reject that.
