1 WED 11/12 wk-5 OBJECTIVE: 9-10 TOPIC –water molecules DO NOW:
daily grade: -6.3 cornell notes/VOC WRAP UP: DW: -6.3 Data Analysis assignment EXT: -online practice quizzes 6.1/6.2 due: -  QUIZ – Fri -DRAW water molecule - LABEL pos/neg ends -LIST properties of water HANDOUTS: -6.3 POGIL -6.3 data analysis COMPLETE / TURN IN: - BEFORE/AFTER SCHOOL: -DW check AGENDA -DISCUSS enzyme lab -6.3 POGIL -FAST PLANTS: water/observe

2 WATER MOLECULE

3 WATER MOLECULE

4 6.2 CRACKER ENZYME LAB BACKGROUND INFO - STARCH
-_________________________________________ IV-INDEPENDENT VARIABLE: __________________________________ DV-DEPENDENT VARIABLE: __________________________________ CONSTANTS: -____________________________ 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

5 6.2 CRACKER ENZYME LAB -starch positive -NO sugar -NO sugar
-sugar positive

6 6.2 CONCLUSION 1- Does the crushed cracker starch? YES NO EXPLAIN-
2- Does the crushed cracker contain sugar? YES NO 3- Does the saliva in test tube #1 contain sugar? YES NO 4- Does the chewed cracker in test tube #2 contain sugar? YES NO -iodine turned purplish black indicating starch -does NOT turn color with Benedict’s solution -does not turn red w/Benedict’s solution -turns red when Benedict’s solution is added

7 6.2 CONCLUSION 5- 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

8 POGIL ROLES -keeps team on task
FACILITATOR -keeps team on task -assures all members participate/understand every question *everyone on same question—everyone contributes—any Qs must be resolved RECORDER -keeps a record of what team did -document team members’ participation -tallies each person input SPOKESPERSON -represents conclusions held by team -presents to instructor--findings/conclusions -asks Mrs. S for clarification when needed STRATEGY ANALYST -keeps log: -problem-solving strategies/methods -what team is doing well/needs improvement -insights/discoveries of course content -individual/team performance

9 STEM CAREER PROJECT - STEM CAREER PROJECT – -on website [HONORS]
ppt TEMPLATE -FOLLOW slide order/requirements -due Nov 21 – print off ppt to hand in ppt THANK YOU NOTE guide/stationairy -write thank you note -put in stamped/addressed envelope -turn in wo/sealing envelope

10 CLASS REMINDERS  - STEM CAREER PROJECT – ppt TEMPLATE
-on website [HONORS] -FOLLOW slide order/requirements - READ/cornell notes circle VOC – underline definition cornell notes – read headings are left column headings - HIGHLIGHT key terms in VOC – SUPPORTING EVIDENCE Qs on EXAM
