To start off our Around the world studies this year, ds and I decided we'd like to make 3D maps of each continent as we "travel" there.
Question: What's the best "stuff" to make them out of so that they will be durable, show some topography, and we can stick pins in them? I have never worked with sculpy or salt dough but they seem like the top contenders,(though will sculpy give me the "relief" effects I need?) but I am clueless, so please let me know what works best for these types of things.
If I use salt dough (or whatever else) what should I use for the base so that we can keep them for a long period (I am thinking of keeping them as Montessori-type activities for dd later).I would like each one to be approximately notebook sized.
Any advice appreciated!

Oh, and recipes would be great, too, for the salt dough, if that is what I need to use. There are so many out there I don't know which one is best, having not tried any of them before.

Basic Salt Dough

1 cup flour
1/2 cup salt
1/2 cup water

Add additional flour or water till consistancy of playdough. Paint with acrylic or poster paints.

Personally, the most impressive map I ever made was of Korea and made out of that winterizing expando foam you spray out of cans to fill cracks around windows, ykwim? It can be carved after dry. Then colored in layers and layers of spray paint. No worries about bugs later eating your hard work, either!

If you didn't want to save the map, try cookie maps instead and decorate with frosting and candies - yum!

We made a relief map of Israel with Crayola Model Magic. It is lightweight and easy to form and we did stick pins in it and it worked great. I collected some old frames from garage sales and made the map inside of it with a stiff cardboard backing. I ended up gluing it on when it dried to make it stick better as I started with it on the glass part first....seeing that I had no clue how it would turn out when I started...LOl...it worked great! nice thing was, I could hang it on the wall when not in use! I found a relief map on the internet and tried to form the map as best as I could with creative input from the kids....it was fun!

I hope this helps!

We've used salt dough, but we've also used "minty cheese" dough using a recipe in the History Links Egypt unit. You use cream cheese, powdered sugar, and a few drops of peppermint extract. It's like those mints made for weddings. Then you divide it and color it with food coloring if you want. We did yellow for the desert, green for the fertile strip along the Nile, and blue for the desert. Then we covered it in plastic wrap and the kids "ate Egypt" over the course of several days. Not very nutrious, I admit!

Theresa,
We use Science Smart for alot of our science projects. It's a book you may want to consider owning . In it, they recommend clay as one option for making a topographic map. They also have instructions for making landform pop-up books that are awesome. Definitely one of my favorite resources.
