Science Puzzlers, Twisters, and Teasers: The History of Life on Earth

A somewhat amusing assignment, this worksheet lists statements that an ancient organism may have made and asks learners to determine what geologic era that each may have lived in. It uses witty word puzzles and fill-in-the-blank-style questions to query learners on the history of life on Earth. You could use this as a homework assignment with middle school earth scientists, but make sure to work through it first so that you will have an answer key prepared.
