Tracking the Summer Solstice

Try this small experiment to observe how the Sun reaches a higher point in the sky as the summer solstice approaches. Just follow these steps:

1. Starting today at 12 noon*, measure the length of a shadow cast by a fixed object (like a flagpole).
2. At noon tomorrow, measure the same shadow again.
3. Continue to measure the shadow each day at noon (weather and weekend interruptions are okay) for a couple of weeks.
4. Are your measurements the same each day or do they differ?
5. If the shadow is shorter each day, does that mean that the Sun is higher in the sky or lower?

*Be sure to make your measurements carefully at the same time each day. 12 noon is best, but other times will work.

      11/1/07 School Library Journal
      Featuring a new author and a colorful redesign, these volumes expertly update Larry Dane Brimner's 1998 editions, and also add a title that looks past Pluto into the Kuiper Belt, the Oort Cloud, and the search for extrasolar planets. Each one matches a clearly reasoned, matter-of-fact text to plenty of small but sharply reproduced color photos and pages of new or restated facts, and rounded off with multimedia lists of audience-appropriate further resources. Despite minor bobbles (for instance, Landau assigns the space probe New Horizons different speeds in Pluto and Beyond Pluto), these remain the gold standard for post-picture-book nonfiction, and should be first purchases for any library that serves fledgling readers.
