Play Science Password!

What You Need:

  • Index cards
  • Pen
  • Paper
  • Science textbook
  • Timer

What You Do:

  1. Use the science password word bank (below) and index cards to create playing cards for the game. On each index card write the word, definition, and words that you cannot say, all on the same side of the card. These are the playing cards you will use when it is your turn to read.
  2. Have your child create 15 similar playing cards using the index cards and his science textbook. Have him use the glossary and write one word with its definition on each playing card, then challenge him to write two logical words he cannot say when reading that term. These will be the playing cards he will use when it is his turn to read.
  3. Shuffle each of your “decks” and let the game begin! Set the timer for 30 seconds. First you pick a card from your pile. Try to get your child to guess the science term. However, you may not simply read the definition, say the word(s) itself, OR say either of the words in the “Do Not Say…” column (no fair changing the tense or form of the word!). See if he can guess the word before the 30 seconds are up. If he guesses correctly before the time is up, he gets 1 point. If you use one of the “Do Not Say…” words or the word itself while trying to get your child to say the correct word, you loose 1 point.
Example Card:
Word: friction
Definition: resistive force that opposes motion between objects
Do Not Say: force, opposes
Example Play:
You could say: slows things down, occurs between car tires and the road, using the breaks to stop a car takes advantage of this concept, there is less of this when you ice skate then when you walk on pavement, air resistance is a type of this, etc.
  1. Swap. Now it is your child’s turn to try to get you to guess one of the words from the playing cards he created. The same rules apply as stated in Step 3. Keep track of the score on the paper.
  2. Continue play until either one player reaches 10 points or there are no cards left. The player to reach 10 points first or with the greater number of points when the cards are gone wins!
