We're thinking about adding pneumatics this year, and our team was wondering what Lego kits we need to have to facilitate this. I see the "Mechanisms Pneumatics Add-On Set" #W979641 (see https://www.legoeducation.com/store/detail.aspx?KeyWords=pne umatics&by=20&ID=1572&c=0&t=0&l=0 or http://tinyurl.com/4amaj8). The verbiage on that item says that this kit "Requires Mechanisms Set (979632)". Is this really true? We already have the NXT and RCX kits, along with a large selection of other Lego pieces. Do we really need the Mechanisms set? Or is that just for people (teachers) who don't have additional pieces in their classroom and need pieces (gears, etc.) to have the pneumatics drive. (As an aside, I can't find on the Lego Education web site where the description lists the pieces in the kit. It is very annoying to buy a collection of pieces without knowing exactly what pieces are in the collection.) Thanks for any help you can provide. ______________________________________________________________ To UNSUBSCRIBE or CHANGE YOUR SETTINGS, please visit https://listserv.jmu.edu/archives/vadcfll-l.html and select "Join or leave the list".
