Teaching Decomposing through Engaging Activities

Activity 1: Nature Scavenger Hunt
Take students outside for a nature scavenger hunt, encouraging them to collect various natural materials like leaves, twigs, and stones. Once back in the classroom, have the students choose one item from their collection to decompose, both in a physical sense and in relation to a larger topic. For example, if a student picks a leaf, they can discuss how it breaks down into nutrients for the soil, and illustrate the food web that depends on this process. This activity not only introduces the concept of decomposition but also fosters a connection to the natural ecosystem.

Activity 2: The Decomposition Timeline
In this classroom activity, provide students with images or samples of different organic materials, such as fruit peels, paper, and wood. Ask them to research and create a timeline illustrating the decomposition process for each item. Students can present their timelines, highlighting factors that affect decomposition, such as moisture, temperature, and the presence of microorganisms. This activity reinforces essential concepts about the natural recycling process and allows students to visualise the passage of time involved in breaking down materials.
