Water and Corn at Variety Boys and Girls Club

March 23, 2017

Today we learned about different ways to water our plants. We reviewed how water is used in our garden via drip irrigation. Then we brainstormed how we might water our plants if we didn’t have such a useful irrigation system. Hand watering with a watering can? Relying on the rain? Then I showed the club members an Olla. I explained how it worked and how it encourages plants to put down deep roots, which helps the plants still get water even when the top few inches of the soil are dry. We filled up the Olla as we talked and watched how it changed colors slightly as it went from wet to dry. The club members were amazed when they felt the Olla was cool to the touch. One club member was late to class and when I asked if someone could explain what we were discussing, a member immediately got up and starting explaining like a pro!

It was awesome.

Then we learned about the evolution of corn! I brought in images that compared teosinte to what we know now as corn. The kids glued them into their garden notebooks as I explained how previous human cultures had used selective breeding to change the plant. Not all plants are exactly alike, so humans would take seed from plants that had the characteristics that they wanted, larger kernels, more rows of kernels, and then planted those the following year. After many, many years of doing this, teosinte became corn.

Then we planted some corn in our garden…we can’t wait to see it grow!
