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)

Starch in Leaf Experiment
![Page 13: Seed Journal DAY 6 water tray??? (~ 3 minutes) Cover your tray or will dry out at window Observations (see): color, new features, growth Measurements:](https://reader035.fdocuments.in/reader035/viewer/2022062519/5697bfa01a28abf838c95175/html5/thumbnails/13.jpg)
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)

ABSTRACT FORMState three science concepts that you learned based on this lab:
WRONG STATEMENTS1. 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.
3. 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
