I don't think getting another tech level will make one of your villagers a Master Scientist, but it might help them succeed in researching more often, so they get to that level faster.

If you have no problem feeding everyone (i.e. you don't have to forage for mushrooms while you're waiting for the crops to come in), then Science 2 is a good idea. But if you are are at all worried about food, I would get Farming 3 and then the Science tech.

But that's just my opinion
