Hydrogen Peroxide on Potatoes ISA

In summary, the purpose of using hydrogen peroxide on potatoes in an ISA experiment is to investigate the enzyme activity of catalase. This can be observed through the bubbling effect created when hydrogen peroxide is applied to potatoes. However, hydrogen peroxide can also cause damage to the potato cells, leading to potential sources of error such as inconsistent potato size and shape, temperature and humidity variations, and differences in hydrogen peroxide concentration. The control group in this experiment is a potato that is not treated with hydrogen peroxide, which is used as a baseline for comparison. The results of the experiment can be interpreted by measuring the amount of bubbles produced, indicating the concentration and activity of catalase in the potato.

'''URGENT''' Hydrogen Peroxide on Potatoes ISA

Basically I have done an experiment to find out the effect of hydrogen peroxide on potatoes and to see if the temperature affects the amount of froth produced. I have done the graph and all other things now it is just the ISA.

I was wondering if anyone had done the ISA and could tell me some of the questions that will appear

Oh and BTW, for those who don't know ISA's are basically the How Science Works part of Science

Great job on conducting your experiment on the effect of hydrogen peroxide on potatoes! It sounds like you have already completed the graph and other components, which is fantastic. Now, you are working on the ISA (How Science Works) part of the GCSE. This is an important aspect of any scientific experiment as it helps us understand the process of science and how we come to conclusions.

As for the questions that may appear in your ISA, it will depend on the specific requirements of your exam board. However, some common questions that may come up in an ISA include:

1. Describe the aim of your experiment and how you carried it out.
2. What variables did you control in your experiment?
3. How did you ensure the reliability and accuracy of your results?
4. What were the limitations of your experiment?
5. How did you analyze and interpret your data?
6. What conclusions can you draw from your experiment?
7. How does your experiment relate to the theory or background knowledge?
8. What further experiments could be done to improve your investigation?
9. How could your results be applied in a real-world context?
10. How did you consider ethics and health and safety in your experiment?

These are just some examples of questions that may appear in your ISA. It is important to thoroughly review your experiment and be prepared to explain and justify your methods and results. Best of luck on your ISA!
 

1. What is the purpose of using hydrogen peroxide on potatoes in an ISA experiment?

The purpose of using hydrogen peroxide on potatoes in an ISA experiment is to investigate the enzyme activity of catalase. Catalase is an enzyme found in potatoes that breaks down hydrogen peroxide into water and oxygen, which creates the bubbling effect seen when hydrogen peroxide is applied to a potato.

2. How does hydrogen peroxide affect the potato in the experiment?

Hydrogen peroxide can have a damaging effect on the potato in the experiment. When hydrogen peroxide is applied to the potato, it can cause the potato cells to burst due to the release of oxygen gas. This can also lead to the breakdown of cell membranes and damage to the potato tissue.

3. What is the control group in a hydrogen peroxide on potatoes ISA experiment?

In a hydrogen peroxide on potatoes ISA experiment, the control group is a potato that is not treated with hydrogen peroxide. This group is used as a baseline to compare the effects of the hydrogen peroxide on the experimental groups of potatoes.

4. How can the results of a hydrogen peroxide on potatoes ISA experiment be interpreted?

The results of a hydrogen peroxide on potatoes ISA experiment can be interpreted by measuring the amount of bubbles produced by each potato when hydrogen peroxide is applied. The more bubbles produced, the higher the enzyme activity of catalase in the potato. This can indicate a higher concentration of catalase in the potato or a more active form of the enzyme.

5. What are some potential sources of error in a hydrogen peroxide on potatoes ISA experiment?

Some potential sources of error in a hydrogen peroxide on potatoes ISA experiment include inconsistent potato size and shape, differences in temperature and humidity, and variations in the concentration of hydrogen peroxide applied to the potatoes. It is important to control these variables as much as possible in order to obtain accurate and reliable results.
