state standard: 3.1.1
This is an activity that has a lot of depth to it. This is a good opportunity to establish groups that have a variety of ability levels in it. It may be an actiity that couldbe done as a whole class activity. Vibrations and how sounds are transmitted and heard is something that students are fascinated by.
Since you're using a third grade standard (and most of the standards dealing with sound are third grade standards), I would also tag this as a "grade 3" activity and also tag with "sound" and "physical science"
Extensions: Connect Earth Science with Art/Social Studies - Ancient Cultures.
Adaptations: Gifted students can research an ancient culture and how they made horizon calendars prior to making their own calendar. ESL & Special Ed students can use pictures to illustrate their calendar and work in small groups. ESL can listen to audio books on topic.
Keep a Horizon Calendar - Earth Science
Many cultures used the rising and setting sun to create calendars. Observe the setting sun once a week for as long as you can to come up with your own calendar.
Supplies: 11 X 17 inch piece of white paper, pencil, compass, watch, and clear view of the western horizon (where the sun sets)
