Part III - Data collection using a Siectronhotometer (tise this tableifstudents Were unablc to complete the exercise on taking Abserhanseriadines nsing colored solutions)- This graph must be hand drawn. You have a set of food extracts (colored solutions) in front of you. Pick one of the food extracts, take the absorbance readings at different wavelengths, using the Spectrophotometer, and record the values in the chart below, Then, answer the questions below and plot a graph using this information, to complete the assignment in class or as homework. PICK ONLY ONE OF THE ABOVE: Extract you picked: Red water Write the absorbance values holmw
Student Activity Which extract did your groun select? Review the information about the spectrophotometer and your answers to the above questions. What do you think will happen when you measure the absorbance of the extract in the spectrophotometer? Your answer to this question should be testable and falsifiable. This is your hypothesis for this experiment. Hupotheris Data Collection When designing an experiment it is important to think about bow you will record the data you will be collecting. Often the data are recorded in a table and then presented in a graph. Graphs provide a compact method of synthesizing all of the data into a single image fhttp-//wwwiscsu. edulabwrite). Gribhing vour Resnlts a. What is the independent variab?e? it Does this ge on the X-axis or Y-axis? b. What is the dependent variable? i Does this go on the-X-axis of Y-axis? c. What kind of graph would be best to use? Circle one below. BAR GRAPH LINE GRAPH d. Explain your graph choice. e. Use the TAILS checklist and graph the data on the following page.

What color of light corresponds to the lowest amount of light absorbed? If the light is not being absorbed, what is happening to it? Explain the relationship between the color of a substance and the wavelengths of light the substance absorbs. Why do you think green plants are green? What wavelength of light is being reflected or transmitted?
