7th Grade
Ancient astronomers and the calendar.
Today we defined the day, the month and the year in terms of the movement of the Earth, Sun and Moon then we discussed and then viewed a video on how the Anasazi used buildings and windows as calendars. We also read page 6-7 in our astronomy book and then discussed why early civilizations needed astronomy.
For next class we need to research an ancient astronomy site of our choosing (like Stonehenge, the Great Pyramids, etc), then bring in craft supplies. We will build a model of our site in our next class session.
8th Grade

We finished our presentations on radioactivity then worked on an activity that explored half life. This was the last activity for our Interactions of Matter book. We will start on Minerals with our next class.
