This unit is a great guide through the new Ohio Revised Standards which shifted some of the matter to third grade and left fourth grade with several standards to cover and build upon.
In this unit, I have included a pre-test/formative assessment (this assesses what they would have learned in third grade and what they will learn in fourth grade), I CAN statements, Vocab list and student vocab cards, vocab game ideas, experiment ideas aligned with EACH I CAN statement, a lab report for experiments, and a final assessment with answer key.
I did not include any reading passages (although I make a few suggestions throughout) because the information for this unit can be easily found in most science texts or on ReadWorks.org
Enjoy - I hope this at least helps you structure your unit!!
