A note about materials: I tried to limit these projects to ones that won't require a lot of supplies & resources---simple fun. However, for many of them you will need a journal----you can create your own out of a brown paper bag and the instructions are here (pdf). For all of them, you will need your imaginations!
It's time for a picnic! But where is your traveling family (the "________walds") going today? Choose a location and have a picnic. What is the weather like there? What are you eating? While setting out your blanket, what do you see all around you? What does it smell like? Someone approaches, what language do they speak? Write it all down in your travel log and after your picnic conduct a little research and find out the real answers to your questions. How close were you in your original answers? Would you want to visit this place?
