Title: Scientific Explanations
When you get your textbook…
• In pen on the inside front cover write
10-(your student ID number).
• Sign sheet with name and student ID
number
• Check your left and right hand neighbor
to make sure they have done the same
*This book can stay at home and you may
use a class copy in class
Hypothesis Card Game
• Procedures:
–Each pair or group of 3 will get two
different decks of cards (red and blue).
–You may discard any kings, queens or
jokers; you will not need them. Jacks will
equal 0, and aces 1.
–Decide who will be the “SCIENTIST” and
who will be “NATURE.” You will change
roles as you play one hand as each role.
Scientists and Nature’s Roles
• “NATURE” obtain a “NATURE’S LAW” card from
Ms. Lavelle.
– Do NOT show the “SCIENTIST” the card and NEVER
tell the “’SCIENTIST” what the “NATURE’S LAW” card
says. Even after the game is over!
– Be sure you understand the pattern before you start
playing cards! The pattern on the card may have
something to do with numbers, colors, odds or evens.
• “SCIENTISTS” try to figure out the pattern by
playing cards and then seeing how “NATURE”
responds.
Playing the Game
• “SCIENTIST”
– Play any card from their deck.
– HINT: Play your cards in an organized fashion so that the
pattern will be easier to see.
• “NATURE”
– Play the first card that follows the “NATURE’S LAW.”
– You may replay a card from the table if you run out of
cards that fit the pattern.
– If you cannot play a card that fits the law you should play
a card face down to indicate “NO DATA.”
– Remember, you are unfeeling and should not hint or help
the “SCIENTIST” out, and never tells “NATURE’S LAW!”
• Continue playing cards until the “SCIENTIST” feels
they have discovered the pattern.
Testing your theories
• Scientists
– When you think they have discovered a pattern,
write an understandable, concise theory .
– Test the theory by laying out three more cards and
hypothesizing what “NATURE” will play
– If the three hypotheses are correct, the
“SCIENTIST” has a valid theory. If incorrect,
continue playing cards until a new theory is
discovered!
• Nature
– Remember nature never tells for sure. Tell the
scientists whether their hypotheses are correct but
not whether their theory is correct. Keep a poker
face 
Ending the Game
Once a valid theory is established, “NATURE”
should return the “NATURE’S LAW” card to the
teacher without showing or telling the
“SCIENTIST” what it says! The players should
then switch roles.

Reminders….
• Jacks equal 0, and aces equal 1. All other cards
equal their face value.
• Play the first card that follows the “NATURE’S LAW.”
• You may replay a card from the table if you run out
of cards that fit the pattern.
• If you cannot play a card that fits the law you
should play a card face down to indicate “NO DATA.”
• Just like in science, Nature never tells!
Binder Set-Up
• First Divider: “CATALYSTS”
Objectives and assignment sections must be completed.
• Second Divider: “NOTES” –Must have table of contents
This is the only way that notes are graded and are a large
part of the notebook grade, so be sure to keep up with
your notes even when absent from class. notes assigned
for homework, MUST be stamped!
• Third Divider: “ASSIGNMENTS” -Must have table of
contents
Labs DO NOT go in this section. It will count as a Lab
grade and remain in your Lab notebook.
• Fourth Divider: “EXAMS and QUIZZES”- Must have
table of contents
