In order for us to make our ecocolumns, we will need about 105 2-liter bottles. Please make sure the bottles are straight-sided (not the curved sides.) The bottles must be clear, not green. Please rinse the bottles with warm WATER only. If you use soap, the live specimens may be harmed. PLEASE allow the bottles to dry thoroughly before bringing to school. Stale soft drink smell is not pleasant! So, if you are celebrating while watching the Super Bowl this Sunday, PLEASE save those bottles and bring them in by next Tuesday. At this point, I have enough bottles for ONE per class, while the preference is to do one per lab group. Please let me know if you have any questions.
