We ran a Go Green night last march & it was a big hit. Our suggestion would be to not over do it with activities because 1/its hard to get people to volunteer to man them all and 2/its just not necessary. just pick a few from the kit and maybe one of your own. We got recycled materials donated froma nearby co and restaurant and had a recycled crafts activity in our art room - it was awesome and families loved it.
We are still in the planning phase... I would love to hear what sort of recycled products were donated from companies and restaurants for the craft projects.
We were initially thinking of having those that come BRING a recycled project that they did at home... but I am starting to think that we could have families make their project or "garbage pal" as a family and display on tables in the the hall for a week or so.
Also, since you are still in the planning phases could you start a recycled materials drive with in your school now? You could either collect through the classrooms or perhaps have a general bin in your lobby?
We're combining our art night w/Green this year. Still in the planning phases (will happen around Earth Day) but thinking: decorating reusble grocery bags (hopeuflly donated by our local Safeway), large styrofoam/trash sculptures, making it a zero (or super low) trash event and earth/green skits and songs by the differnt grades. Looking into also adding a plant or seed sale as a fundraising component.
Rather than ask Safeway to donate bags--they then become waste all over again--start collecting your own. Our school is currently collecting grocery bags and other resin class 2 & 4 plastics in a competition with two other schools to win a bench donated/made by TREX, the company than makes composite plastic decking. Since Sept. we've collected over 13,000 pieces. Just think of what they would've looked like blowing through the woods, floating in the creeks, and not decomposing in the landfill.
We're also involved with TerraCycle.net and their website and FB page have great ideas and photos of what to do with recycled materials. Good luck:-)
