They look good enough to drink.  Milk chocolaty brown with a foam top.

Sorry.

It’s a half full jar of soil sample, topped with water and a drop of dish detergent.  The particles disperse in the liquid and settle.  We will measure the total height and then the height of each layer:  sand, silt and clay.  The percentage of each will determine, quantitatively, what the soil texture is.  We can compare this to the texture determined from the texture-by-feel analysis of a few weeks ago.  Quantitative and qualitative analysis of the same sample:  Will the findings agree?

While we worked on that, David and Steve set up temperature probes in the soil outside.  We have probes located at 36″, 24″, 12″, 6″ and in the outside air.  The probes are hooked up to a little computer, connected to the ethernet.  That means the temperatures will feed out all day and all night, whether we are in school or not.  We can look at the temperature readings at this website: https://cosm.com/feeds/97558
