Essential question How do scientists investigate the natural world? 7

Who do you agree with?  Four students were having a discussion about how scientists do their work. This is what they said:  Antoine: “I think scientists just tryout different things until something works”.  Tamara: “I think there is a definite set of steps all scientists follow called the scientific method.”  Marcos: “I think scientists use different methods depending on their question.”  Avery: “I think scientists use different methods but they all involve doing experiments.”  Which student do you most agree with? ___________________  (Place your sticky circle on the front board above the student name to create a class graph and participate in class discussion.) 8

Essential question How do scientists investigate the natural world? 11

Science is Like a Puzzle  We often wonder if scientists are “wrong” because they can’t answer all the questions we might have to ask.  We know lots about the universe. But, we don’t know everything.  Does that mean that we can’t explain things based on what we do know now? 12

Science is Like a Puzzle  Just recently, the International Astronomical Union decided that Pluto was not a planet.  Does that mean that earlier astronomers were wrong?  What was the basis of the change? 13

Science is Like a Puzzle  This activity will take you through the steps of the scientific method and help you figure out how scientists make predictions and draw conclusions.  It will help you begin to think more like a scientist yourself. 14

If you give a student a cookie? 20

Invention!  Ruth Graves Wakefield invented chocolate chip cookies in 1930 when she ran the Toll House Inn in Whitman, Massachusetts.  At first Ruth did not mean to make chocolate chip cookies..  Ruth’s Inn was famous for her chocolate cookies.  One day, they sold so well that she was out of chocolate dough.  Then she thought to use broken-up bars of semi-sweet chocolate!  However, the chocolate did not melt and make the cookies chocolate. They were just in place and sweetened the dough!  The cookies were an ultimate success.  At first her new cookie invention was called the “Toll House Cookie.” 21

Qualitative vs. Quantitative Data Qualitative DataQuantitative Data  Overview: Deals with descriptions.  Data can be observed but not measured.  Colors, textures, smells, tastes, appearance, beauty, etc.  Qualitative → Quality  Overview: Deals with numbers.  Data which can be measured.  Length, height, area, volume, weight, speed, time, temperature, humidity, sound levels, cost, members, ages, etc.  Quantitative → Quantity 22

Definitions Qualitative Data  Deals with descriptions. Data is observed but not measured. Quantitative Data  Deals with numbers. Data which can be measured. 23
