Keep interesting gadgets on your desk and around your classroom and create a stimulating atmosphere to set the tone for learning! I found this unusual fake butterfly in a jar this summer for my desk. It's attached to a very thin wire which is battery-operated (the battery is under the lid to the jar). The wire simulates incredibly realistic movements of a real butterfly caught in a jar. Here it is:
Yesterday a few of my students noticed this, and before long I had a crowd gathered around my desk. Several students wanted to know where I had bought it and how much it cost, because they wanted to buy one for their bedrooms. But the best reward of all for me was seeing a group of football players hunched over the jar, saying "That's awesome!" I'm glad I bought it...it was worth it :).
