• Access to the internet for research
• Printable worksheets (to be created by the teacher)
• Art supplies (colored pencils, markers, paper) for creative activities

Before starting the lesson, ensure that the student has a quiet space to work and access to a computer or tablet for research. Prepare printable worksheets that include fun facts and questions about New Zealand leeches.

Activities

1. Research and Presentation

   The student will conduct research on New Zealand leeches using the internet. They will gather information about their habitat, diet, and role in the ecosystem. After this, the student will create a short presentation (3-5 minutes) to share their findings with a family member or friend.

2. Creative Drawing

   Using art supplies, the student will create a drawing of a New Zealand leech in its natural habitat. They can include details such as plants, water, and other animals. This activity encourages creativity while reinforcing what they learned about the leech's environment.

3. Fun Facts Worksheet
