Tuesday we continued with Photosynthesis and used our pop it bead models to work through the first stage of photosynthesis.
Here is a rundown of the days daily questions, notes and activities
Notes and pics of the activity:
This was an INCREDIBLY important step during photosynthesis for two reasons.
#1. It released the oxygen gas that we need to breathe.
#2. It helps to power the creation of ATP by adding a phosphate group on the ADP. This is going to help fuel the NEXT stage of photosynthesis.

Energy from the Sun - Causes electrons to get excited - Water that has entered via the roots.... Gets Split apart......(see next picture)
 |
| The Hydrogen ions are then pumped through different photosystems but what WE really care about is that each oxygen binds with one OTHER oxygen to create O2 (molecular oxygen that we breath) which is then released into the atmosphere) |
DURING this time - Two energy carriers are created. Remember.... Energy is STORED in chemical bonds and RELEASED when bonds are broken. We used out brightly colored beads to represent our energy molecules:
 |
| NADP and ADP are in the chloroplast already. |
 |
| Another Phosphate is Added to ADP to create ATP. |
 |
| A Hydrogen ion is added to NADP to create NADPH |
These two energy molecules are what will fuel that second state of photosynthesis.
Wednesday you went through the book and filled out a directed reading about the light dependent reactions.
