For two months, members of our team have been teaching students at Seattle's William Grose Center to develop a local microgreens production facility. One of the exercises was to produce a crop in a small container. The adjacent image shows Keyshawn's results.
The seeds were sown and kept in darkness for three days before exposure to sunlight. The result after seven days total was as shown.
Other students with other varieties but under the same regimen had different results. A report on those results and how they can be the basis of a bit of surreptitious STEM learning will be published here soon.
