A friend emailed me this link about icebergs/glaciers the same day someone asked me how to homeschool on the cheap.
Perfect timing.
What Kathy sent me is a perfect example of a free science lesson. Use your imagination and you can come up with many more.
First, adapt for the age of your children.
Look up the terms iceberg, glacier and glacier calving in the dictionary. If you don't have a dictionary, use one of the many online ones.
Read this background about the video:
On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland . The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest below water.
Watch the video--warning--it has one word in it so you might want to preview or leave the sound off. The video is here. http://www.youtube.com/embed/hC3VTgIPoGU?rel=0
Discuss the video.
Do a simple experiment with ice and water--put ice cubes into a clear glass bowl of water and observe. How much of the ice is above the water surface? How much ice is below the water surface??
Make your own earth out of dirt and sand on a box flat. Add a large chunk of ice, and tilt it to a slight angle. Watch what happens as it moves across the earth.
Then, check out some of the free websites about glaciers for worksheets and such. Google and you can find more..

You can also take the terms you learned and make them spelling words for the week. Also use one of the free crossword puzzle makers online to use the words in a crossword puzzle.
There you go. A free science lesson.
