Robots vs. Aliens works for 2 reasons: 1) everyone has an opinion on this debate and 2) the kids decide who wins. I patterned the idea after the Shark vs. Train Story Action Pod I made, but fleshed it out into a 30-45 min program
(I feel the need to stress that if you're going to try elementary outreach, in order to get teacher buy-in you're going to have to be able to promise 30 min door-to-door. That way you can be in and out in that magical time period between lunch and math, or during lunch and recess, or after Special Areas but before the bell, when the teacher actually has the time to do a fun activity. If you happen to be scheduled on a Friday with no spelling test, however, for instance, you may be able to stretch it out to 45. Have a craft or game ready if you get that extra time.)
