LOOK THROUGH THE POWERPOINT AND ANSWER QUESTIONS 1 AND 2 IN YOUR JOURNAL.
1. WHAT HAVE WE LEARNED ABOUT OBSERVATIONS FROM THESE
SLIDES? Answer in your journal.
2. READ CONCLUSIONS ABOUT OBSERVATIONS JOT DOWN IDEAS THAT SEEM DIFFERENT AND LOOK UP ANY CHALLENGING
WORDS.
• OBSERVATIONS OF OPTICAL ILLUSIONS TEACH US THAT
INFORMATION IS NOT ALWAYS NOTICEABLE AT FIRST.
• AS HUMAN BEINGS, AND AS SCIENTISTS, WE MUST MAKE
QUANTITATIVE OBSERVATIONS SO THAT WE OBJECTIVELY
JUDGE AND PROTECT AGAINST THE TENDENCY TO SEE
ONLY WHAT WE EXPECT TO SEE.
• IN THIS WAY, WE MAKE OUR BEST EFFORT TO AVOID
SUBJECTIVITY.
• A LARGE SAMPLE BRINGS US CLOSER TO THE TRUTH.
