Use observations to describe patterns of what plants and animals (including humans) need to survive. This will be a clear example of what plants vs animals need to survive that also provides the students with visuals.
This anchor chart would be a great way to integrate science into reading. This chart would be an easy way for students to look at insects and see what they are, can, and have. They could then use these things to write about an insect.
This chart would be a great tool when trying to identify where the animal lives. To make this more useful and grade appropriate, students could include facts and major Texas bodies of water on the back!
