Need a source of low-cost journals or other nature journaling supplies for your classroom? Here are a few resources I have found. Please add your own suggestions in the comment section.
Sketch For Schools Journals. Spiral bound customizable journals. I recommend the intermediate weight textured paper. You can add your school logo or other custom page to the front (though this does add cost). This might be a good place to print the naturalist tools sheet (ruler, protractor, and other tools).
Other Nature Journaling Materials
Large Drawstring Backpacks. Buy these in bulk for price discounts. Every student can customize and carry their own journal kit. The brightly colored drawstring bags run when wet so go for the white-beige bags. Sold by the dozen. Two versions: low-cost ($1.75 each), more durable ($2.25 each).
Non-photo Blue Prismacolor® Col-Erase® Pencils. Box Of 12 ($9.49)
Magnifying Glass (be sure to tie a string through the end so students can hang them around their necks.)
