Carolina Tips - February 2009  | Carolina Biological Supply Company | |  | |  |  | Compost Tea
Middle School
Submitted by Patricia Richard, Locke Middle School, Billerica, MA
Here’s a quick, hands-on project for your next Earth Day Celebration or Sustainability Fair. Have your students make compost tea, a nontoxic alternative to chemical-based plant food and insecticide, by doing the following: | | | 1. | Wrap a half gal of compost securely in cheesecloth. | | 2. | Place it in a 5-gal bucket filled with 2 gal of water that has been aerated with an aquarium pump for one hour to remove chlorine. | | 3. | Add a half ounce of unsulfured molasses to the water. | | 4. | Run the aquarium pump for several hours and then immediately pour the tea into small spray bottles. Label the bottles and add a warning that this “tea” is for application to plants and soil only; it’s not for drinking! |
During your Earth Day Celebration, allow students to spray the tea directly on plant leaves or to apply it to the soil in the school garden. At your Sustainability Fair, students can give sample bottles of the tea to attendees.

Sheep organs are a great way for students to study mammalian anatomical structures and to compare the form and function of major organs.

For decades, Carolina has been well-known for high-quality preserved specimens for dissection. But did you know that we also offer a variety of alternatives to specimen dissection? Learn about Plastomounts and why they are an effective alternative to dissection.
