Include your hypothesis (constructed in Procedure Step 1) here. © 2013 eScience Labs, Inc. All Rights Reserved Does blue dye have more mass than red dye? 2.Was your hypothesis proven or disproven? Provide data-based evidence from your experiment to support your claim. Be sure to analyze the numbers you recorded to transform the information from data into results. ?????Yes, I do believe so, the blue dye travel much faster than the red dye in both liquids. In date collection it shows it moves at higher rate 3. Select an appropriate method to graphically display the data you recorded in Tables 6 and 8. Use a graphing or drawing program on your computer (e.g., Microsoft Drawing®, Microsoft Excel®, etc.) to accomplish this task. Be sure to include components such as a title, x and y axis labels, units, etc. Also, indicate which variable is the independent variable, and which is variable is the dependent variable. Include your graphs below. © 2013 eScience Labs, Inc. All Rights Reserved ????? 4. Which dye diffused the fastest in corn syrup? Which dye diffused the fastest in your chosen water? ?????Blue in the corn syrup. Red in the tap water 5. Does the rate of diffusion correspond with the molecular weight of the dye? ?????In blue I feel it did in syrup but the corn syrup is denser. However tap is a lighter substances and the red dye is lighter substance. So I think it depends on the density of the substances. 6. Does the rate of diffusion change over time? How might this affect your calculated diffusion rate compared to the actual diffusion rate? © 2013 eScience Labs, Inc. All Rights Reserved ??? Yes, as the (solution) reaches equilibrium the rate of diffusion decreases. ?? The greater the variance in concentration between two ranges, the greater the rate of diffusion 7. Describe why the medium the dyes diffuse through can affect the rate of diffusion. How does this relate to nutrient transport into cells? It is a progression, which involves movement of a substances from a region of it’s absorption to an area of it’s lower absorption. The additional absorption we can do the additional nutrients we can achieve. © 2013 eScience Labs, Inc. All Rights Reserved
