Earth Science Word Search


Earth Science Word Search is a word search puzzle using glossary terms associated with the Earth Sciences. The Earth Sciences include the study of meteorology, geology, and astronomy.

 

Earth Science Word SearchThe words can be found running left/right, up/down and diagonally within the array of letters. This activity can be a fun way to introduce many of the terms a student will encounter in an Earth Science class. Clicking the image will show a full-sized version of the puzzle optimized to fit on a single sheet of paper. Alternatively, a PDF version can be downloaded for better quality and easier printing.

If you have trouble finding a few of the words, feel free to take a peek at the solved word search (or you could download the solved PDF).
