Photosynthesis is the process by which plants, algae, and certain bacteria use sunlight to convert carbon dioxide and water into glucose and oxygen. This process is essential for the survival of plants and is the primary source of energy for most living organisms. In this lab, we will be using floating discs to investigate the role of light in photosynthesis.

To begin the lab, you will need to gather a few materials, including a light source, floating discs, and a test tube. You will also need a steady hand and good eyesight to accurately measure and record your observations.

To set up the experiment, start by filling the test tube with water and adding a small amount of baking soda. This will create a basic solution, which is necessary for the floating discs to remain buoyant. Next, place the floating discs in the test tube and position the light source so that it is shining directly on the discs.

Once the experiment is set up, it is time to begin collecting data. Observe the floating discs over a period of time, taking note of any changes in color or movement. You may also want to measure the oxygen levels in the test tube using a dissolved oxygen meter.

As the light source shines on the floating discs, the chloroplasts within the discs will absorb the energy from the light and use it to power the process of photosynthesis. This will result in the production of glucose and oxygen, which will cause the discs to change color and move more actively within the test tube.

In conclusion, the floating discs photosynthesis lab is a simple and effective way to investigate the role of light in photosynthesis. By observing the changes in the floating discs over time, you can gain a better understanding of how plants and other photosynthesizing organisms use sunlight to produce energy.

Using a measuring cylinder, 50cm 3 of dilute acid X was poured into the conical flask. I hope I will be able to do the same for the next 5 subjects, which I will be writing in 2016. The technique to make a summary is really helpful. What is gas B? You may draw a diagram to help answer the question. Thank you to those wonderful teachers behind the screen, for providing your support with every step of the way, by putting together those intriguing presentations and videos. What I am grateful about is that this exercise has boosted his confidence to a level I had not seen before in the subjects that he took his revision in.

Thank you very much for helping me along the way and for creating an online revision course that I believe has helped countless numbers of students all around the world. SHAMINI DE SILVA UAE When I first saw the Physics and Chemistry courses on your website, I knew that this was my solution to all my doubts and problems in both the subjects. There are so many things I never knew and was being taught in the course. They're very professional in handling this. Finally, you could use an indicator like litmus paper, it will change to red with sulphuric acid, but there will be no change with sodium sulphate. My daughter Nawal Amir completed her english revision course with igcse center. Regards, Haneea Yasir UAE "Dear IGCSE Team, Thank you for all the help on this website and the revision classes.

Ur videos have helped me a lot and I realized all my mistakes and will try my best not to repeat them again. Louisa Wibisono Indonesia IGCSE Centre really opens my mind about the point to get full mark in the exam. You can use a metal carbonate in which carbon dioxide will be produced with sulphuric acid but there will be no change with sodium sulphate. . This wouldn't have been possible without your endless support. Thank you so much!! Outline a method you could use to show the presence of E110 in a food colouring. Two further tests are carried out and the following observations made.

The timer was started and the volume of gas collected in the measuring cylinder was measured every 30 seconds for three minutes. Thank you for all the motivation that you gave. My mock exam before was really poor. You can add a metal, in which hydrogen is produced with sulphuric acid, but no change in sodium sulphate. .

My son said it is so good, it has very good explanations in a way that he can understand. From the bottom of my heart, I am truly grateful. I would be more than happy to advice all my friends to look up your site and purchase your revision courses in order to help their children as well. If a current flows through the substance when it is molten or dissolved, it is an electrolyte. It was an easier way to learn English.

Advance planning and a workable schedule for the duration of the course made the target achievable in a very comfortable manner. Petronilla Switzerland Dear IGCSE Team, I am writing to sincerely express my gratitude for the wonderful job that you TEAM are doing to ensure OUR children perform well in their exams. E was an aluminium salt. Electrolysing aqueous solutions of ionic compounds can be more complicated than electrolysing molten compounds because the water molecules can provide hydrogen ions and hydroxide ions. Haneea Yasir Dear IGCSE Team, thank you for all the help on this website and the revision classes. I used all the techniques learnt in the course and can't stop congratulating the team.
