There is a lot you can do with materials you have at home and what you can readily find outdoors. However, there are times when just the right tool, book, curriculum or example can be important and helpful.
Below are a few companies and their websites that carry lots of educational materials of all kinds. I suggest you check them out just to see what is available.

At Home Science Tools, we share a commitment with families seeking effective ways to teach science at home. We have been providing affordable curriculum and lab products to help families teach and learn science for 11 years.
From unit studies on Astronomy to detailed high school Physics textbooks, we have curriculum available for all grade levels and learning styles. For elementary grades, our number one science curriculum recommendation is Bob Jones University Press. The extensive scope and sequence of this curriculum is designed to give students a great foundation for more complicated high school level science courses.
We highly recommend Apologia curriculum for teaching high school science. Apologia offers courses in General Science, Physical Science, Biology, Chemistry, and Physics, as well as four advanced courses and three elementary courses! Our Apologia curriculum is discounted 30%!
Finding the right hands-on materials for your science curriculum can be intimidating and time-consuming. To make teaching science easier for you, we have developed unique Science Kits that provide all the materials you need in one convenient package. Each kit contains all those hard-to-find items from preserved specimens to labware. We have kits available for each science course published by Apologia, Alpha Omega, A Beka, Bob Jones, Castle Heights, Christian Light and Switched-on-Schoolhouse. Each kit is discounted 10% off our low everyday prices!

Environmental Science Education Products
Forestry Suppliers Inc.
While this retailer is specifically directed to the wildland management professional, there are a lot of tools and training items that teachers might find useful. They are a bit on the spendy side at times, but perhaps you can use them to find items that you would like and then buy a similar item elsewhere cheaper.
