If the leaves are placed in a solution of sodium bicarbonate with four grams of baking soda, then the rate of photosynthesis will increase and the leaves will float faster. ]]> 2017-10-30 00:58:58 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201562770 Introduction 096965 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201567844 Our experiment brought up the question of whether adding nitrogen in the form of ammonia within Windex would speed up the rate of photosynthesis within our floating chads. The hypothesis we settled on was that yes the nitrogen will increase the rate of photosynthesis due to the fact that nitrogen is present in fertilizers meant to speed up growth.]]> 2017-10-30 01:30:54 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201567844 Procedure and Materials https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201570396 2017-10-30 01:46:43 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201570396 olagirl151 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201571549 2017-10-30 01:54:17 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201571549 olagirl151 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201571610 2017-10-30 01:54:40 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201571610 Graph 153766 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201578319 2017-10-30 02:42:35 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201578319 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201578611 2017-10-30 02:44:26 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201578611 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201579238 2017-10-30 02:49:11 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201579238 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201579328 2017-10-30 02:49:48 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201579328 Graph https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201579425 2017-10-30 02:50:48 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201579425 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201579700 2017-10-30 02:52:24 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201579700 Conclusion https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201581306 2017-10-30 03:05:27 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201581306 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201672557 2017-10-30 12:11:35 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201672557 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201672775 2017-10-30 12:12:12 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201672775 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201673133 2017-10-30 12:13:21 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201673133 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201674103 2017-10-30 12:15:59 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201674103 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201674236 2017-10-30 12:16:23 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201674236 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201674571 2017-10-30 12:17:15 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201674571 Conclusion https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201679622 I’m conclusion, at lower temperatures ( cold water ) the enzyme doesn’t have enough energy to meet many substrate molecules, so the reaction was slowed. On the other hand, when the temperature was greater ( warm water ) the particles in the reaction moved quicker and were able to collide more, therefore the rate of photosynthesis also rised]]> 2017-10-30 12:30:44 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201679622 Hypothesis https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201685621 The control group will have the most photosynthetic activity compared to the hot and cold water because it will have an optimal temperature. ]]> 2017-10-30 12:46:13 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201685621 Materials https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201687034    Materials

The warm and cold water could have become room temperature overtime which would effect the number of floating leaves, because the temperatures become more optimal over time. ]]> 2017-10-30 12:56:25 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201690302 Conclusion - Angel Lam https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201709552 Adding ammonia (windex) to our sodium bicarbonate solution showed that the rate of photosynthesis for the spinach leaves increased. Compared to the control group, the disks started floating faster than theirs, but in the end we had less disks float to the top. After 2 minutes, we had spinach disks start floating, while the control group’s spinach disks didn’t start floating until after 6 minutes. ]]> 2017-10-30 13:36:10 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201709552 Procedure 096965 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201756736 Materials: 
One hole puncher, 3 plant leafs, soap detergent, windex, one 300ml beaker, three 100ml beakers.
  1. Punch out 30 leaf dots making sure to not use the root of the leaf.
  2. Place ten leaf pieces in each syringe. 
  3. Create a solution of sodium bicarbonate with soap, water, one drop of windex in the 300ml beaker and add it to the three syringes.
  4. Remove oxygen from the syringes and create a vacuum within the syringe by using your finger to cover the syringe and then pull the plunger. Repeat this process until all leafs fall to the bottom of the syringe.
  5. After this place each set of leafs into their own solution of sodium bicarbonate in an 100ml beaker and place under light.
  6. Record how many leafs begin floating during one minute intervals.
  7. Compare your results to the control group.

The y-axis is time and the x-axis is the number of floating CHAD]]> 2017-10-31 02:36:26 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201993916 Hypothesis and Conclusion. 094904 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201994081 Our hypothesis is that the CHAD will take 7 minutes to begin floating when following the instructions of the lab. 
In the lab we discovered that the Chad began to float at 8 minutes instead. This change could have came from a user error or it is the average time for photosynthesis to begin again within the leaves. ]]> 2017-10-31 02:37:47 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201994081 Experimental Error 094904 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201994450 There could be evidence of an error because out of our three groups only one group did not float. In this experiment we could have encountered error when we were taking the gas out of the leaves earlier in the lab. At this point in time we could have taken too much carbon dioxide and did not leave enough for the one group of CHADS to begin photosynthesis again. ]]> 2017-10-31 02:40:32 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/201994450 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/202145898 2017-10-31 14:12:06 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/202145898 https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/202146285 2017-10-31 14:12:43 UTC https://padlet.com/katrina_pandya/qbit9ys8bgpq/wish/202146285
