Engage your older elementary students with this multimedia look at the moon and its influence on the tides. There is text that explains the concepts of apogee and perigee, many pictures of phases of the moon and tides in many different locales, and a multiple-choice quiz to check comprehension. The site also offers the choice of listening to the text being read, and the ability to print out the information. A great way to supplement your science curriculum.
