Crawling Farming Tractor Kit (Mechanics Laboratory)
Build 20 different battery-powered tractor models with this unique S.T.E.M. kit. While the illustrated instruction book only shows how to build one model, there is a downloadable app which includes instructions and digital animations of how to build the rest of the models. This kit includes 250 pieces to build and rebuild. Once the featured models have been built, use creativity to design new tractors. Use trial and error to discover what pieces and features work best for your creation. The tractors are powered by a battery pack which requires four 1.5 V AA batteries (not included). The downloadable app is compatible with Android™, Apple®, and Amazon®. ~ Brianna
These kits provide incredible insight into the world of physics and engineering-and fun! Each box highlights different vehicle designs, ranging from single-prop seaplane to combine harvesters. These exciting builds also offer great learning experiences in pulley, lever, and gearing fundamentals! Once finished, these very detailed models include functioning mechanisms such as transmissions, differentials, propellers, and steering systems! Each kit provides very helpful building instructions.
