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.

Ur videos have helped me a lot and I realized all my mistakes and will try my best not to repeat them again. The gas is more dense than air. I wish best of luck to igcse team and a great lot of thanks to Leana especially. The teacher always motivates us to do better. Two further tests are carried out and the following observations made. If a current flows through the substance when it is molten or dissolved, it is an electrolyte.

Thank you so much!! Grades may say otherwise but for me that confidence has been instilled outside his usual classroom setting. Louisa Wibisono Indonesia IGCSE Centre really opens my mind about the point to get full mark in the exam. Thank you for giving me a higher level of confidence to do IGCSE! 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. At no point of time did he feel as if he was rushed, this is in addition to being in the school basketball team , keyboard player in the band and other extracurricular activities. Thank you for all the motivation that you gave. . E was an aluminium salt.
You may draw a diagram to help answer the question. 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. Mohamed Essam Egypt Dear IGCSE Centre, I would like to take this opportunity to express how grateful I feel for your support. Experiment 1 The apparatus was set up as shown in the diagram. Give a test for chlorine.
What is gas B? To test for conductivity, include a sample of the substance in a circuit that contains a source of direct current eg a cell or power pack and a bulb or an ammeter. Fatim Egypt Hello IGCSE Centre, I wanted to thank you from the core of my heart for not just supporting me, but also other students who are in need of these amazing classes!! I used all the techniques learnt in the course and can't stop congratulating the team. . There are three tests, you can use a metal carbonate in which carbon dioxide will be produced with sulphuric acid but there'd will be no change with sodium sulphate. While the program was intensive and focused on the finer aspects of language skills, I firmly believe that it has also taught him some very important life skills - the first and foremost being time management. Whether you get the metal or hydrogen during electrolysis depends on the position of the metal in the reactivity series: the metal will be produced if it is less reactive than hydrogen hydrogen will be produced if the metal is more reactive than hydrogen SEE REACTIVITY SERIES. This wouldn't have been possible without your endless support.
The timer was started and the volume of gas collected in the measuring cylinder was measured every 30 seconds for three minutes. How could you show that a solution of benzoic acid is a weak acid? Shamini Vinodya De Silva UAE Dear IGCSE Centre, I would like to take this opportunity to express how grateful I feel for your support. . My daughter Nawal Amir completed her english revision course with igcse center. . 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. 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.

I couldn't resist the urge to keep watching the videos all day long! Using a measuring cylinder, 50cm 3 of dilute acid X was poured into the conical flask. I will not hesitate to recommend these revision classes to my friends. Experiment 2 Experiment 1 was repeated using 50cm of dilute acid Y. Eagerly waiting for the results. There are so many things I never knew and was being taught in the course. . You can add a metal, in which hydrogen is produced with sulphuric acid, but no change in sodium sulphate.
Words cannot define how comprehensive. Thank you so much again. 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. Alvin Fujito Indonesia I thank IGCSE Centre for their assistance in my 2015 IGCSE exam. My son said it is so good, it has very good explanations in a way that he can understand.
Continue the good work, IGCSE Team. Outline a method you could use to show the presence of E110 in a food colouring. Best wishes, Vishal Varadraj UK Hi IGCSE Centre, I wanted to thank your team for all the advice they gave me including examiners tips and tricks. 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. I feel that I just aced the paper 2 English exam. You can add a metal, in which hydrogen is produced with sulphuric acid, but no change in sodium sulphate. To any parents considering registering their children for this revision, I can attest that this revision is worth it not only to make the children get good grades but to also re-assure them that they just need the confidence to believe in themselves.
Show clearly on the graph how you worked out your answer. 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. 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. To be an electrolyte, a substance must be able to conduct electricity. Thank you for all your help, surely and amazing website, would love to have a similar one for A levels.
It was an easier way to learn English. They're very professional in handling this. In terms of safety, explain why it is necessary to warm carefully. The solution was divided into four test-tubes and the following tests were carried out. I hope I will be able to do the same for the next 5 subjects, which I will be writing in 2016. Some of the observations are shown below. The technique to make a summary is really helpful.
