3. When you conducted the investigation, how did you collect appropriate data? elephant toothpaste

Answer 1

When conducting the investigation on elephant toothpaste, appropriate data can be collected through several methods.

Firstly, the materials and measurements used in the experiment can be noted down accurately. This includes recording the quantities of hydrogen peroxide, dish soap, and potassium iodide used, as well as any additional substances or variables that were introduced into the reaction.

Secondly, observations of the reaction can be made during the experiment. This involves noting down any changes in color, texture, or volume, as well as any other visual or sensory changes that occur throughout the reaction process.

Furthermore, video or photographic documentation can also be employed to capture the reaction in real-time or at different stages. This visual evidence can be used to provide a more accurate representation of the reaction and its characteristics.

Lastly, it is important to keep track of any data collected during the experiment, such as the time it takes for the reaction to occur, the height or volume of the foam produced, or any other measurable outcomes of the reaction. These quantitative data can be recorded using measuring tools, such as timers, rulers, or graduated cylinders.

By combining these methods, one can collect a range of appropriate data during the investigation on elephant toothpaste, allowing for a comprehensive analysis and understanding of the reaction.
