-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
