DO NOW:daily grade: -6.3 cornell notes/VOC
WRAP UP:
DW: -6.3 Data Analysis assignmentEXT: -online practice quizzes 6.1/6.2 due: -6.1-6.2 QUIZ – Fri
-DRAW water molecule - LABEL pos/neg ends
AGENDA-DISCUSS enzyme lab-6.3 POGIL---------------------FAST PLANTS: water/observe
HANDOUTS:-6.3 POGIL-6.3 data analysis
COMPLETE / TURN IN:-BEFORE/AFTER SCHOOL:-DW check

EXPERIMENTAL GROUP: _________________________CONTROL GROUP: _________________________
-starch can be converted to sugar-enzymes speed up a chemical reaction
-enzyme [amylase] in saliva
-starch converted to sugar
-crackers-indicators-hot water bath
-chewed cracker exposed to amylase-cracker broken, not exposed to amylase
6.2 CRACKER ENZYME LAB
-starch positive
-NO sugar
-sugar positive
-NO sugar
6.2 CONCLUSION1- Does the crushed cracker starch? YES NO
EXPLAIN- 2- Does the crushed cracker contain sugar?
YES NOEXPLAIN-
3- Does the saliva in test tube #1 contain sugar?
YES NOEXPLAIN-
4- Does the chewed cracker in test tube #2 contain
sugar? YES NOEXPLAIN-
-iodine turned purplish black indicating starch
-does not turn red w/Benedict’s solution
-turns red when Benedict’s solution is added
-does NOT turn color with Benedict’s solution
6.2 CONCLUSION5- INDICATE: What effect did the saliva have on
the starch in the cracker? 6- PROPOSE what you think the addition of heat
(water bath) did to the reaction occurring in test tube #2-
7- HYPOTHESIZE: Would the reaction in test tube
#2 have occurred regardless of the addition of heat?
-converted starch to sugar
-sped up reaction
-yes, but slower
POGIL ROLESFACILITATOR-keeps team on task-assures all members participate/understand every question
*everyone on same question—everyone contributes—any Qs must be resolvedRECORDER-keeps a record of what team did-document team members’ participation-tallies each person inputSPOKESPERSON-represents conclusions held by team-presents to instructor--findings/conclusions-asks Mrs. S for clarification when neededSTRATEGY ANALYST-keeps log: -problem-solving strategies/methods -what team is doing well/needs improvement -insights/discoveries of course content -individual/team performance
