EXPLORE Investigation Threading the Needle In Question: How do you define success in a scientific investigation?In Question: How do you define success in a scientific investigation? Purpose: Use terms “limits” & “diversity” correctly and construct & analyze data tablesPurpose: Use terms “limits” & “diversity” correctly and construct & analyze data tables Procedure: Through Questions:Procedure: Through Questions: Review How To #2 on pg 544 TQ#1: Read entire procedure & construct a team data table TQ#2: Perform procedure & record team data in lab book TQ#3: Analyze data according to Step #11 & record in lab book TQ#4: Record team data on class data table TQ#5: Review How To #3 pg 551 & construct a bar graph of class data

EXPLORE Investigation Threading the Needle Wrap Up:Wrap Up: OQ#1: Did you need to change your data table during activity? OQ#2: Did your data table make it easy or difficult to analyze data in Step #11? OQ#3: Describe the limits that influenced your ability to perform task successfully. OQ#4: How much diversity was there in your team’s results? OQ#5: Describe how closely your team’s results match results of other team’s in class.

EXPLORE Connections How Do You Spell Success In Question: Define how your team determined if you were successful in the Threading the Needle ActivityIn Question: Define how your team determined if you were successful in the Threading the Needle Activity Purpose: Develop a class definition of success when treading the needlePurpose: Develop a class definition of success when treading the needle Procedure: Through Question:Procedure: Through Question: Class Discussion: 1) Describe how team determined which members had most success on Star Tracers; 2) How many definitions of success in Star Tracers; 3) Describe team definitions of success in Threading the Needle; & 4) Are teams with most success better than other teams in class? TQ#1: Develop class definition of success in Threading the Needle Wrap Up: Out Question:Wrap Up: Out Question: OQ#1: Record class definition of success in Threading the Needle

EXPLAIN Investigation If at First You Don’t Succeed In Question: Why would you redo an experiment several times?In Question: Why would you redo an experiment several times? Purpose: Students will compare first set of data to new data and discuss why new data is more reliablePurpose: Students will compare first set of data to new data and discuss why new data is more reliable Procedure: Through Questions:Procedure: Through Questions: TQ#1: Review How To pg 540, Construct T-chart for Social Skill, discuss how to move quickly & quietly to groups, then fill in t-chart TQ#2: Construct a team data table similar to or same as you used in Threading the Needle Perform same procedure for Threading the Needle using the class definition of success TQ#3: Record new team data on class data table

EXPLAIN Investigation If at First You Don’t Succeed Procedure: Cont.Procedure: Cont. TQ#4: construct a new bar graph of new class data TQ#5: Compare old class graph to new class graph Wrap Up: Out Question:Wrap Up: Out Question: OQ#1: Did your number of successes change? If so explain why. OQ#2: List any new limits you think were due to the class definition of success. OQ#3: Describe differences between old & new class graphs. OQ#4: Decide which graph has more reliable information about class success. Explain your choice. OQ#5: List specific Strategies that your team will use to move into your group more quickly & quietly.
