I have 20+ copies of these workbooks from a public school that could be used for a co-op or group. They are 68 pages divided into 4 units: Energy and People Power; Using the Energy of Flowing Water; Catching the Wind's Energy; Using the Energy of Sunlight. Junior high/high school level. None of the books have been written in and are in excellent condition. I will trade 2 books for 1 buddy credit or 3 for 1 buddy credit if 6, 9, 12, etc., are ordered. |

You need to post bookshelf promos and deals in the sticky thread, not here in the regular forum. Thank you. |
