Monday is MUD DAY! Come prepared for your Winogradsky Column construction! I have some spoons, a couple of bowls, measuring spoons, etc, but other items are gratefully accepted. Wear something you can get dirty. I have some gloves, but if anyone has extras, I would love to have some, too!
I will bring some hardboiled egg yolks and I will round up some chalk for the calcium. Some students have asked about bringing in extra ingredients (charcoal briquette, sawdust, etc.) You'll have to send those items.
These columns will be studied throughout the school year. We've got some really creative and funny "pseudoscience" articles on the laptops. These will be presented on Thursday of next week! For more ideas for the column, go to http://serc.carleton.edu/microbelife/topics/special_collections/winogradsky.html for some additional ideas!
Don't forget your time capsules! They are due Tuesday, 9/21!
Enjoy your weekend!
