Camp participants assemble solar models.

Participants had many different models to choose from and experiment with.

This model is solar-powered but does not use electricity.

A participant collects a water sample at the stormwater wetland.

After a water sample is collected, the container is sealed so it can be analyzed in a safer, more convenient or (on rainy days) drier location .

Water is poured into a vial for testing.

Some tests require adding multiple chemicals to a sample to indirectly measure a parameter of interest (this process is called 'titration'). Here, one chemical is extracted from a storage jar.

Here, that chemical is added to the water sample.

Finally, a second chemical is added to the mixture. When enough of this second chemical has been added, the mixture will change color. The amount of that second chemical that was added reveals the concentration of the parameter of interest (which otherwise could not be inexpensively measured in the field).

Participants begin working on their green-space design projects

Participants continue to make progress on their projects.
