How to Play Science Trivia

The great thing about trivia is that it is a very flexible activity, so it can easily fit your group of players! You can make it simple by just reading the questions on the cards and having anyone answer. You can also make it more complex by setting up a whole competition.

To create a more complex game setup, you could designate a time/scorekeeper and a card reader. Then you can divide the group up into as many teams as needed. The card reader reads a card and the first team to buzz in now has a chance to answer the question. If the answer is incorrect, the other team has an opportunity to steal the question and answer it. You can play until a certain number of points has been reached, or you can set an overall time limit.

You can easily adjust the rules of the game to fit your needs!

Why Play Science Trivia?

While playing this trivia game, your kids will be learning without even realizing it! They are practicing skills like:

Reinforcing new vocabulary
Memorization
Learning new facts

Trivia is great on the go game! You can play while on car rides, at home for family game nights, at school, and more!

I especially love that this game does not require much setup or clean-up. While trivia is a great family activity to connect with each other, the kids can get the game going themselves. This gives me time to get other things on my to-do list done.
