No, I did not generate investigation questions to demonstrate that properties of substances are changed in a chemical reaction. However, here are some example investigation questions related to the elephant toothpaste experiment:
1. How does the concentration of hydrogen peroxide affect the volume of foam produced in the elephant toothpaste reaction?
2. Does the addition of a catalyst, such as yeast, affect the rate at which foam is produced in the elephant toothpaste reaction?
3. Can different types of soaps or detergents be used as substitutes for hydrogen peroxide in the elephant toothpaste reaction?
4. How does altering the temperature of the reaction mixture impact the height and duration of the foam produced in the elephant toothpaste reaction?
5. What happens to the pH level during the elephant toothpaste reaction, and how does this affect the properties of the resulting foam?
6. Can the elephant toothpaste reaction be reversed or undone by introducing a specific substance or condition?
These questions could be investigated through experimentation and data collection to determine how the properties of substances are changed in a chemical reaction, such as the formation of foam in the elephant toothpaste reaction.
