This kit from K’NEX Education will help kids get started building the models in “Teaching Physics With TOYS EASYGuide Edition.” The benefits of using K’NEX Education Kits are that they’re a fun and economical alternative to single-use equipment. The kit includes a plastic storage case with moveable dividers and transparent locking lid. Additional pieces used in the EASYGuide Edition (as noted on the companion CD-ROM) can come from any K’NEX set or can be ordered as an add-on pack.
