Independent Variable: Temperature
Dependent Variable: Number of floating disks
Factors held constant:
- Time 
- Number of Leaves used
- Light Source

In the beakers, pour about 3 cm worth of bicarbonate solution and label 4 of them by the temperature (40º, 30º, 20º, 10º). The last 2 beakers will be used for the hot plate and ice bath
2.Grab the ice and make an ice bath and insert a beaker with the bicarbonate solution.
3. Turn on the hot plate and have it heat up, then put a beaker with bicarbonate solution.
4. Using the hole puncher, cut out 40 disks, 10 for each beaker.
5. Remove the plunger from the syringe and insert the 10 leaf disks into all of the syringes

On the contrary, however, those exposed to a warmer temperature had an increased rate of photosynthesis seeing as nearly all the disks in 40 degrees celsius floated. ]]> 2023-01-30 19:03:16 UTC https://padlet.com/dzamora3457/tire1xn1banyukem/wish/2461949035 dzamora3457 https://padlet.com/dzamora3457/tire1xn1banyukem/wish/2461969790
6. Put the syringes and pull in some solution. Have it reach more than the 5 mL mark and tap out the bubbles, then after tapping out the bubbles expel the extra solution until you have 5mL
7. Create a vacuum by using the opening of the syringe with your finger and pull back the plunger. Hold it for 10 seconds. With this you will see the air bubbles forming around the disks.
8. Agitate the syringe or invert the syringe while maintaining. Helps remove the air bubbles.

Release the plunder with the tip being upwards to see if it will sink. If it doesn’t , repeat the process again until all 10 of the disks sink.
10. Once it sinks, pour the disks and the solution into the beakers.
11. Carefully, add the hot bicarbonate solution to your beaker until the desired temperature is achieved( 40° C, 30°C)
Similarly add the cold Bicarbonate solution to a different beaker until it is 10°C
12. Place each beaker under its light source counting how many floating disks are in each after every minute for ten minutes.]]> 2023-01-30 19:27:28 UTC https://padlet.com/dzamora3457/tire1xn1banyukem/wish/2461984896 dzamora3457 https://padlet.com/dzamora3457/tire1xn1banyukem/wish/2462005326 This is due to the decrease in cellular activity in colder temperatures  this is due an increase of necessary kinetic energy for reactions like photosynthesis to occur. Some weakness in this experiment  would be the lack of multiple trials.]]> 2023-01-30 19:41:22 UTC https://padlet.com/dzamora3457/tire1xn1banyukem/wish/2462005326
