What kind of effects do humans have on their environment? Review key anthropogenic vocabulary with a fill-in-the-blank handout. You may wish to use this as an ongoing glossary, review before a test, or even create a crossword puzzle or Wheel of Fortune game using these words. With a blank for each letter, the handout will help ensure kids are spelling terms correctly, and they even get the first letter to help jog their memories. Not using all of this verbiage in your class? No worries; you can modify the document to work for your class.
