• Grade level: Middle Elementary

• Subject Area: Science

Brief Description

    Students conduct background research on the decomposition process, soil composition, and the life cycle using the resources provided for directed Internet searches.
Objectives

• Students will conduct research using Internet resources to enhance their understanding of the life cycle, soil composition, and the decomposition process.
• Students will work in collaborative groups to select a topic for investigation and to conduct Internet research.

Materials and Resources Needed

Internet resources: Refer to the list below of resources on worms, gardening, and soil to help students get started on their research.
Activity Description

• Have collaborative groups of students discuss a topic of interest for investigation that is related to the worm bin and plant growing lessons, as well as to humans' place in the life cycle. Possible topics may include soil erosion, the growth and distribution of crops on a farm, vegetarianism, a particular plant of interest.

• Consult the list of resources provided and then have groups of students conduct Internet searches to collect information on their selected topic. Discuss appropriate Internet behavior and etiquette. Students may need assistance in learning to use the Internet.

• Students collaborate over email with the partner groups arranged in Lesson 2. They may choose to send questions over email to experts in the area they have chosen to explore.

• Have students consider their place in the life cycle. Discuss with them in the whole group the effects of human activity on the lives of other organisms.
