Jeopardy Physical Science Review for Chapter 11 and 12 Test

Rules• We will divide into 4 groups, each group needs to elect

a spokesperson. Every one needs to be actively seeking for the answer, but the spokesperson will write down the correct answer on the whiteboard.• There are 10 categories, with each category having 5

questions. They increase in difficulty by the numbers.• We will rotate among the 4 teams, each team can

select their category, if you get a question wrong, then the next team in line can answer the question.• The winning team will receive a prize.
