1. Physics – Review Linear Motion It’s time to play… Physics Jeopardy

2. Rules for the Game When it is your team’s turn, select a category and an amount. After Mr. Dillon has finished asking the question, any team may buzz in. If you buzz in early, you will not be called on. If the team that buzzes in answers correctly, they get those points and choose the next category. If the team answers incorrectly, they lose the points. Mr. Dillon will then re-read the question so the other teams can have a chance to answer. A team is NOT obligated to answer if they do not want to. There will be a Final Jeopardy question at the end of the game where teams can wager the points they have earned. Any questions?
