We talked about the importance of soil and created a vermicompost (worm compost) bin.  

Learn about how this rich compost helps plants and find instructions HERE

and HERE.

 

We discussed soil pH and learned how to take soil samples for testing.  We tested our samples using a pH kit and again using red cabbage.

We also looked at soil porosity, comparing drainage for clay, soil, and sand  Learn more HERE   and HERE about why soil porosity is important to plants.

We wrapped up by planting the seeds that we started last week.  We’ll study them, take measurements, and make observations over the next 4 weeks.
