The goal is to guess what the hidden technology is by using Yes or No questions. One student volunteer gets to see the technology and then answers questions the other students ask. Three student volunteers write down the questions that are asked and the Yes or No response. The teacher will tell which volunteer to write down each question. Yes or No question each round.
Teams huddle to agree on a team question.
If they cannot agree, they lose their turn. Listen to the answers to every question in order to ask better questions. After the team asks a question, if they believe they know what the technology is, they may guess, but wild guesses will just slow down the game. The questioning continues around and around the classroom until someone guesses correctly, or you hit 20 questions.
