Variables (Independent, dependent, control, uncontrolled) (discuss) Likely impact upon the investigation How the variable will be changed/ measured/controlled Independent variable The temperatures [ 20℃ (control), 30℃, 40℃, 50℃, 60℃, and 70℃] Heating the green peas may allow the texture or color of increase in the colorimeter. The variety of temperatures will give us a view of the effectiveness on the green pease color. Dependent variable Colorimeter Colorimeter measures the amount of light transmitted through a wavelength. You put the grinded green peas into the colorimeter. The colorimeter measures the absorbance. Experimental Control: Colorimeter at 20℃ This variable will show us to what extent will the value’s differ …show more content…
Which can change the texture and appeal for the green peas. The amount of peas grinded and poured into colorimeter can have a certain effect on the value of the calorimeter. It will debunked the data and not prove the hypothesis. In the colorimeter we have the ability to control the amounts of wavelengths. Keeping it at different wavelengths will not only change the data’s value be able to assess the data if not using the same wavelengths. Water has a high specific heat capacity. Keeping it at the same amount for peas can allow us to hold in consistent amounts of heat to be able to get the right data. If the cover is not closed during process of finding the absorbance of the colorimeter, there will be light entering into the solution which can alter the data. Use a thermometer and affectively watch the temperature rising and decreasing. Asses the situation and effectively collect data. Pour in the same amount of peas for every trial. This will give us the reliable data on how temperature can affect the color of the peas not the concentration. Altering the wavelength capacity can change the data. Maintaining the wavelength not only keeps consistent data but allow us to analyze it for accurate
