Around here it is common to send your kids to a few summer camps. They are typically week-long sessions of day camp programs with varying themes.
I was really pleased to see bits of green inspiration in their experiences.
One camp which my kids attended was a science and art program. I knew the kids were going to learn about building a water system, but was kind of amazed at the enthusiasm for (and retention of) the curriculum. My 7 year-old was telling me about how we need to catch rain water from our roof and even drew me a diagram of how we could!
He also made a fun water filter experiment with 3 increasing levels of filtration.
My 5 year-old made a model of a "green cabin"—with insulation and solar heating.
They also attended another camp which I knew would be more obviously eco-focused since it is a farm-based program. The kids help with all the farm jobs and at the end of the week they host a farmers market. What I didn't expect and was excited to see was that the camp shirts were from an organic cotton company and produced in the US.
It's nice to find inspiration in unexpected places.
