Product Description
Free standard shipping - Get perfect samples no matter what type of soil youre collecting. Teachers Joseph Cirillo and Bruce Rowland have come up with this practical. feature-filled device with ease-of-use being the keyword. The easy to use boring handle can be easily removed and replaced by a special extractor unit. Then, simply turn the extractor handle to easily and neatly remove your soil plug intact. The unit also features a depth measurement scale (up to 8 inches) so that you can easily collect multiple plugs from uniform depths for comparison. The unit is even easy to clean - simply use the boring handle and/or a stiff bristled brush. How easy is that? Grades 5-10. Includes: completely assembled sampler device, soil collection bags and labels for a class of 30, and a teachers guide complete with background information, suggested activities and reproducible student worksheets.
