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.

Exploring
Sheep Organs
Sheep organs are a great way for students to study mammalian anatomical
structures and to compare the form and function of major organs. Article
includes labeled drawings and step-by-step directions for dissecting the
sheep brain, eye, and heart. |
Animal
Dissection--There Is No Substitute, but There Are Alternatives
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.
