Remember to always have a print rich environment. In my science center I always have words that go with the theme and also books that go with the theme. I also have a class journal and pencils in the science center where the children can add their observations.
I do the same with the math center. I keep a math class journal and lots of math books. They then go in and add their own notes in there for all to see.
This is a way to get them to write and to know that writing has meaning.
