The JKHA fourth grade students welcomed a group of wiggly guests to their worm bins in science. Acting as a group of investigators, they are setting up a worm compost bin and maintaining the bin. As a part of the adventure, the students are learning about vermicomposting, the environment required for worms to live, the time needed for vermicomposting to occur and how the worms convert food waste into nutrient-rich fertilizer. They will also get to observe the worms and study their growth and population over a period of time. Students will harvest the worm bin over a period of months and will be using it to manure the JKHA herb garden. The fourth grade students recently invited in JKHA sixth grade students to show them what they have been working on.
