This was one of our recent science experiments. We're studying the digestive system in Apologia Human Anatomy and Physiology. The clay in this experiment represented poop (Yes. I said "poop.") and the nylon stocking represented our intestines. Norah had to work the clay through the stocking just like our smooth muscles in the intestines have to work poop out of our bodies. Gross? Yes indeed. But, it was also a very effective demonstration of what goes on inside us.

"...the child should have a set time everyday to read for fun. Begin with half an hour for first graders, and build up to an hour of reading time daily... This is an important part of the child's education: it improves his reading skills, teaches him the habit of sitting still with a book, and reminds him that reading is fun... free reading ought to be spent on literature at or slightly below the child's present reading level so that he can simply enjoy himself. The easier reading will help him increase his speed." The Well Trained Mind: The Guide to Classical Education at Home by Jessie Wise and Susan Wise Bauer

Andrew Peterson's Songs That Celebrate Marriage and Family

We were willing to stand at the back, but we were able to find space on a bench at the back of the hall.

I know it is a problem that I need to work on if for no other reason than for the sake of my poor husband and daughters who have to hear the same albums everyday for a year. No, really. A year. At least. I have been giving myself permission to buy new music for this reason. So I came home that evening or maybe it was the next day and I purchased three of hi

Astronomer Shoe Boxes for Challenge B

  Avril finished her astronomer shoeboxes for Challenge B.   The Challenge B students have all done research and projects on astronomers throughout this first semester.  Now, students choose two (or more) astronomers in secret and provide clues to the astronomers' identities in their shoeboxes.   For instance, if an astronomer made telescopes, sang opera, played piano, discovered binary stars or Uranus, studied eclipses, lived in a simple, log cabin, or made a map of Washington D.C., you might include some of those items to your shoe boxes as hints.  Student bring in their shoeboxes, and classmates get a chance to guess who the astronomers are based on what's inside the boxes.  Can you guess who Avril's astronomers are based on the pictures above?  Hint: Her two boxes actually represent three astronomers total.
