2. AIM: How does photosynthesis occur
AIM: How does photosynthesis occur? OBJ: Given notes, 3 experiments and activity sheet SWBAT explain the process of photosynthesis in plants with 70% accuracy. DN: Seed Journal (~ 3 minutes); HW check- Photosynthesis & Light Booklet. College Style Lab Review Results: Elodea CO2 Test, Guess Which Gas, Light & Starch LAB WRITE-UP & ASTRACT FORM HW: Complete Photosynthesis in Plants Lab (due Monday). Work on Plant Activity Sheet, Plant Exam Oct 16.

3. Photosynthesis
For Elodea CO2 Test: Bromothymol Blue: Yellow indicates CO2 present For Guess Which Gas? Baking Soda + Water = CO2 GAS Liquids – more dense, sinks; Gas – less dense, rises For Light & Starch (letter E) Test: Note: iodine ─ dark leaf – starch (LIGHT) iodine ─ light leaf – NO starch (COVERED)

4. College Style Lab Report
Title: Photosynthesis in Plants Problem: How does photosynthesis occur? Hypothesis: ??? Materials: ????? Procedure: Explain 3 experiments, namely 1. Elodea CO2 Test (4 test tubes) 2. Guess Which Gas? (beaker, funnel, test tube) 3. Light & Starch Test (plant, letter “E”) Results: 1. What did you learn/discover? (Hint: used Bromothymol Blue for what? Blue color, Yellow color) (Hint: used Iodine for what? Dark color, Light color) 2. Answer all lab questions. Abstract Form: complete

5. MATERIALS:
Elodea CO2 Test:
Guess Which Gas:
Light & Starch “E”:

6. PROCEDURE (steps taken):
Elodea CO2 Test:
Guess Which Gas:
Light & Starch “E”:

7. RESULTS (learn/discover):
Elodea CO2 Test:
Guess Which Gas:
Light & Starch “E”:
Answer All Lab Questions.

8. DAY 1 (Light + CO2 in water)

9. DAY 2 Light, but what happened to the CO2?

10. Guess Which Gas?

11. Guess Which Gas?

12. Starch in Leaf Experiment

13. Light & Starch Experiment
RESULTS: Dark part of leaf = light present, starch produced Light part of leaf (covered) = No light, no starch CONCLUSION: Light required for photosynthesis Light required to produce starch (food)

14. ABSTRACT FORM State three science concepts that you learned based on this lab: WRONG STATEMENTS 1. I learned about mass and how to calculate mass. 2. I learned about volume and how to find volume. 3. I learned about density and how to calculate density. CORRECT STATEMENTS: 1. I learned that mass is the amount of matter (atoms) in a substance and it is measured using a balance (unit: grams). 2. I learned that volume is the space an object occupies and for cubic/ rectangular solids we use a ruler where V = LxWxH; for irregular objects (cork, pebble) we use a graduated cylinder (water displacement method) to find volume I learned that density is the amount of mass divided by the amount of volume; it represents the internal atomic arrangement of atoms in a substance
