This is what I did. I did four days of camp one for each topic. I supplemented the activities with games, snacks and playtime. We did the whole summer camp in our local park with teenage and adult volunteers for help and supervision.
This curriculum would work great if broken up to work as part of an after school program or club. It could be broken up in many ways. For example over 4 weeks, three times a week or over twelve weeks, once a week. This could be run by a teacher, after-school helper, or volunteer from the community.
Teachers could use one or all of these activities to teach environmental science to their classes. Getting students doing hands-on science outdoors is so important and it has proved to be way more effective in changing ecological behavior than indoor environmental science. Many of these activities would make excellent supplements to environmental science lessons.
Many of these activities are fairly cheap and easy to do at home with kids. They are a great way to engage kids in science in a fun way at home or with friends.
As a Girl Scout myself, I think it is so important for troop leaders to engage girls in fun science as well as engage them in community issues like protecting the environment. Many of these activities would be easy to do during a meeting. They are fun and provide girls with scientific knowledge they can use to advocate for the environment.
During summer camp we put sidewalk chalk with environmental messages all along the walkway to our local beach. The kids loved drawing with chalk and felt great about the idea of every person walking to the beach seeing and reading their messages.
Food has a large environmental impact. Take the opportunity to discuss food waste, the impact of food production, and the types of foods that are more and less environmentally friendly (vegetarian vs meat eaters, land use, etc.).
During camp we played lots of camp games including many versions of tag, zoo, and categories ("this is a game of concentration, no mistakes or hesitations..."). A couple other fun camp games/ ice breakers that were new to the kids were:
This book is a fun read that's all about protecting the environment. Kids are interested in the story and learn the important message Dr. Seuss has to share.
During camp we walked down to the beach so the kids could collect their own shells for the ocean acidification activity, but any hiking or walking in nature is fun and reminds kids what we have to be grateful for and protect.
During camp, we did a student lead discussion on ways to protect the environment at the end of each day.

I had students complete this on the first day of camp and at the end of the last day of camp to measure how much they learned.

I based these questions off of the discussions we had during camp and used it as a follow-up survey about a month after the camp was over. It asks for responses from both the students and the parents of kids and measures the broader impact of the curriculum.
