2.  Put science to the test! Observation is a large part of science. Bring in fresh materials: rocks, shells, feathers, plants, etc. and allow students to make observations. I am thinking in my fourth grade room this semester I am going to set up one easy science experiment a week and allow students to observe. We take for granted they know what happens when a glass of water is left out for a week or a plant is not given water. Set it up and allow them to document the changes.
