Physical properties of urine Color, Odor, and transparency Examine the urine specimen for color, odor, and transparency Record your observation Specific gravity Weigh a 100-mL graduated cylinder Fill the graduated cylinder with 50mL of urine sample and weigh. Get the weight of the urine by subtracting the weight of the empty graduated cylinder from the weight of the graduated cylinder with the urine sample Divide the weight of urine by volume. The value obtained will be your urine density. Assuming that the density of water is 1 g/mL, the density of the urine is equal to its specific gravity. pH Using a pH paper or a pH meter, determine the pH of the urine Properties Observation Color Odor Transparency Specific gravity pH What is the pH of normal urine? What is/are the reason for the observed pH of urine?

Help me create a digital dashboard for tracking "your life". Choose four areas you want to track and determine 3 ways in which you would measure each area. (ex. If you track eating habits, you might want to measure calories and place unacceptable levels in red and acceptable levels in green.) Then determine whether you can find any correlations among the areas in your life. It should simulate what your preferred dashboard will look like ( a good dashboard provides all required information at a quick glance).
