Can you give me some ideas for a project for kids 7-12 yrs old? This 'workshop' will be 1-2 hrs long, 6-12 kids inside a greenhouse on tables. I need to use fairly inexpensive materials. Have available all kinds of plants-greenhouse and nursery. Past projects have included: moss garden, herbs, built a birdhouse.

You might also build a mason bee house (to attract pollinators to the garden) or a bird nester (which provides materials for birds to build their nests): http://www.nwf.org/Get-Outside/Outdoor-Activities/Garden-for-Wildlife/Gardening-Tips/Build-a-Bee-House.aspx?CFID=28625570&CFTOKEN=64ada46852abd4d-4CFC037F-5056-A868-A085CD4C912568A8
