CRHS Science


Welcome To Red Wolf Country!

Welcome to the 2011-2012 school year! In the navigation tab to the left, you will find links to the various classes that I teach. Each page will have a unit guide for topics, homework, assignments due, and posted project and test dates. Remember, some quizzes may be announced while others may not be. Be prepared at times! The classroom is located on the second floor in room B202.

Throughout the school year, the science department is in need of certain supplies. These are listed below. If you are able to provide us with any of these items, it is most appreciated. We use the consumables below for various labs and activities throughout the year.

Links for Grocery Cards to benefit CRHS!

Harris Teeter: Our number is 5131. You may link your VIC card for the school year by giving this number to the cashier one time. Or cut and paste the link below to go to the online registration page.

The Weaver Street Market program is a bit different from these others. You purchase a gift card for a certain amount (say $50, $100, etc) and give our number, 224, to link the card at purchase. THIS IS NOT THE SAME AS THE CO OP NUMBER!! Use the gift card to pay for groceries or to eat at Panzanella's Restaurant in Carrboro. Each quarter, CRHS PTSO will get 5% of sales paid for with these gift cards. Once you use up that card you can recharge it.
