Today, a one-sentence lab: How does the moisture sensor indicate soil moisture to us?
This lab went so well! Kids learned how to hook up the sensors to multimeters following the Vegetronix Techno-Gardner video (scroll a bit), how to add water in a measured fashion, and how to account for our soil samples absorbing water kinda slowly.
More on this lab on my full-length blog.
