Lamotte's Topsoil Tour
Preface
The goal of the Topsoil Tour is for students to examine, discover,
and compare the physical and chemical properties of soil.
Real Science
The procedres used in the Topsoil Tour are simplified, but similar
to those used by soil scientists throughout the world. Tell your students
that they are scientists while on the Tour. The Tour introduces the underlying
scientific principles of soil science while stimulating curiosity and enthusiasm
by involving students in hands-on investigation of their own soil samples.
Your students will become familiar with the chemical concepts of:
- Dissolving
- Concentration
- Reaction
- Extraction
- Dilution
Active participation in this project involves the processes of:
- Observing
- Communicating
- Comparing
- Measuring
- Organizing & Classifying
- Relating
- Analyzing & Summarizing
- Applying
Safety
The TesTab reagents used in the Topsoil Tour are designed with safety
in mind. The single-unit, foil packaged TesTabs are easy to distribute and
dispense. The single-test packaging minimizes the amount of material ever
in the hands of an individual student. Store TesTabs in a safe place and
only hand them out when ready for immediate use.
Outline
This outline divides the Topsoil Tour into seven units. The activities
in each unit introduce new skills and reinforce the skills learned in the
previous unit. The test procedures include "waiting time" that can be used
to reinforce the short lessons and games included in the Tour.
