Hydrogen Peroxide Experiment Analysis

The video tutorial guides viewers through a biology experiment that can be done at home. It begins with preparing a potato solution, followed by setting up the experiment using hydrogen peroxide and coffee filters. The experiment involves measuring the time it takes for a filter paper to sink and rise in the solution. Viewers are instructed to conduct multiple trials, dilute the hydrogen peroxide, and record their observations. The video emphasizes the importance of writing a procedure and analyzing data, while also encouraging viewers to adapt the experiment based on available equipment.

What is the first step in preparing the potato for the experiment?

• Mash the potato

• Boil the potato

• Peel the potato

• Cut the potato into pieces

Why is it important to use cold water when blending the potato?

• To make the solution thicker

• To keep the enzymes active

• To change the color of the solution

• To make the solution sweeter

What is used to filter the potato solution?

• A strainer

• A coffee filter

• A piece of cloth

• A paper towel

What is the purpose of using a stopwatch in the experiment?

• To measure the temperature

• To ensure the solution is cold

• To time the blending process

• To record the reaction time

What is the concentration of the hydrogen peroxide solution used initially?

• 4%

• 3%

• 2%

• 1%

What should be done if the paper does not sink in the solution?

• Add more water

• Use a different solution

• Try again with a new piece

• Increase the temperature

How many times should the experiment be repeated with the 3% hydrogen peroxide solution?

• 10 times

• 20 times

• 5 times

• 15 times

What is the final concentration of hydrogen peroxide to be tested?

• 1.0%

• 0.5%

• 1.5%

• 0.2%

What is the main focus of the experiment according to the instructor?

• Achieving a specific outcome

• Writing a detailed procedure

• Getting the fastest reaction time

• Using the latest equipment

What should be included in the write-up of the experiment?

• Only the results

• The instructor's comments

• The procedure and data analysis

• A list of materials
