What do I do in this protocol?
This protocol measures the amount of water in soil using a simple procedure.
In this process you will:
1) Identify a site.
2) Collect wet soil. Dry it under a heat lamp. Measure weight of dry soil.
3) Collect standardized samples for soil density comparison.
4) Submit your data to GLOBE.gov.
What do I need to participate?
Some scientific equipment: A gram scale, graduated cylinder, heat lamp, and a can or ring: You can buy the standard instruments in a kit here. Youth groups or individual youth participants can apply to receive a free set here.
Miscellaneous household items: Ziploc bags, a garden trowel, a ruler, sharpie pens, paper, and pencil to record data along the way.
Time: Collecting a sample is quick and easy, but it takes a couple days for a sample to dry. You will have to be able to check on the sample from time to time to find when it is dry, then record a measurement.
A computer or phone: You will data using the same data form for trowel samples and can samples. You will need access to the internet to do that. [Make the form a bookmark so you can return easily!] Not sure what the difference is between the sample types? Watch the training video to learn more.
