Experimental design
Observation
• Observation – A process that helps gain
information. Sight, smell, touch, taste, hearing
– Example related to the game• There are 6 total pieces used in the game. Three are one
pattern, three are a different pattern.
– Example unrelated to the game• I came home from school, my house smelled good.
Inference
• Inference- Being able to make a conclusion
based on evidence. An educated guess based
on what is observed. An assumption.
– Example related to the game• Since the pattern of G’s pieces match the side pattern,
that is where G starts.
– Example unrelated to the game• House smells good; mom is cooking.
Hypothesis
• Hypothesis- A proposed explanation for an
observation. An idea that is testable.
• Example related to the game– If P moves all pieces off of the board before G, then
player P wins.
• Example unrelated to the game– If it smells good in the house, then my mom must
be cooking.
Conclusion
• What you came down to when relating back to
hypothesis. You make a conclusion after
observing your data. 2 outcomes!
• Hypothesis was true
• Hypothesis was false
– Example related to the game• My hypothesis was correct, the first player to move all
pieces off the board wins the game.
– Example unrelated to the game• My hypothesis was incorrect, my mom is not home so
she can’t be cooking. (revise hypothesis) maybe smell is
coming from neighbor’s house.
Theory
• Set of related hypotheses are confirmed to be
true and are related to as facts. Theories can
explain a great amount of data in the natural
world.
• Highly tested
• “just a theory”
Exit slip
• What is the difference between a conclusion
and theory?
• In a single sentence, state your game findings
using 4 vocabulary words.
