Hands on Worms

*Grade: 6 (5-7)

Time Required

45 minutes

Group Size

Approximately 20 (entire class works together).  Portions involve groups of two for "pair and share" discussions.

Cost Per Group

Three remote temperature displays @ ~$25

Three compost temperature loggers @ ~$100

Assumes access to a computer and the data logging software (comes with loggers)

Total ~$375

*Summary

This sustainability activity focuses on designing and kicking off the experiment to determine which composting design or designs offer the best composting environment.   Students will learn about instrumentation, measurements, experimental design and controls, and will gather data in order to evaluate several alternative composting designs and determine which designs are most effective.  Students will get to work with temperature sensors, data loggers, and measuring devices during the analysis and conduct a variety of engineering-related analysis skills such as data gathering, filtering and graphical analysis.  Issues associated with data quality and controls will be discussed along with the hands on activities.

*Engineering Connection

Engineers help address sustainability issues and work in a variety of ways to support the three Rs+C: Reduce, Reuse, Recycle and Composting. Engineers are crucial to designing waste reduction and waste management systems that are as effective, efficient, and cost-effective as possible.  Comprehensive waste management systems are likely to include composting as a way to take our biodegradable kitchen and plant waste and turn it into useful products such as natural fertilizer.  This activity focuses on the issues and tools associated with gathering data for a long-term experiment and preparing to use the information appropriately to evaluate experimental results.

Each group needs:

*Introduction / Motivation

This activity provides the students with a chance to compare the difficulties and challenges of "old-fashioned" manual recording with automatic data recording with sensors and loggers. Students explore factors affecting their data and work through the process of selecting and configuring appropriate equipment.

Vocabulary / Definitions

Word

Definition

Compost

Both the organic material that has been decomposed and recycled and the act of creating the system to intentionally recycle materials and create useful soil.

Data Logger

A device for recording information over time.
