Observations and Measurements

During my time at IHOP I observed some very interesting things about todays society. Before I entered the establishment I noticed a happy family returning to their car. So I made the assumption that these observations would all be the same because of possibly of great service and environment. I was gravely mistaken. I walked into IHOP and was seated in a great spot to observe people. The situations I observed were; a group of 5 teenager girls, a old man by himself, and it seemed to be two female friends with their newborn babies. The first thing that I could connect perfectly with a theory was the Social-Conflict theory. The friends with the children were set off towards the corner, and hidden away from the rest of the restaurant. Several other families were in that general are also. I didn’t find that equal at all. They were secluded, as if only families with young children had to sit there. The body language of the waiter towards them was impatient; he kept on tapping his pen on his pad and sighing overdramatically. When the parents apologized to…

precision of freshwater partial pressure of CO2 (pCO2) estimates. To better understand observational uncertainty in CO2 flux from inland waters, here we conduct an analysis of historical observations and take new field observations at the North Temperate Lake Long Term Ecological Research (NTL LTER) site to quantify random errors in freshwater carbon system. We further estimate errors contribution to the precision of pCO2 derived from multiple carbonate equilibria and identify other sources of…

inventor puts one end of the straw into the tray of solution and blows through the other end for 5 seconds and the largest bubble is recorded with the rulers. The free floating test used a 80 ml beaker of solution, a straw, and a ruler. A inventor took the straw and put one end into the 80 ml of solution and capped the other end with their finger to capture the solution, and blew through the end that was capped by the finger. The free floating bubbles were allowed to descend to the ground where…

My group noticed that for Solution 1 the bubbles the were created were rather small and usually multiple were made. It was hard to make one large bubble and it usually lasted a short amount of time. The solution was also quite thin and sudzy. Solution 2 was a thin liquid and would also form multiple bubbles but there seemed to be an equal chance of making a small or large bubble. Solution 3 was a thick liquid and it usually made one large bubble but it was harder to blow a bubble. For Solution 4…

alternatives to restore oak savanna on the site. b) Specific Objectives i) Survey trees on the Grady tract. Identify them, record their location and measure DBH (diameter at breast high). Include any observations that could be considered important. ii) Measure percentage of canopy density in the Grady tract area. iii) Measure woody debris depth in the Grady tract area. iv) Create maps showing canopy cover, woody debris depth, and what species dominate the Grady Tract. 2. Personal Objectives a)…

requires the measurement of a quantity on the atomic and macroscopic scales with the same unit of the measurement. Robert Millikan, an American experimental physicist, measured the exact charge on an electron in early 1900s; this resulted the required measuring to become possible. The charge of a mole of electron is known as Faraday constant. (94,485.3383 coulombs per mole of electrons) Also the estimated value of the charge on an electron is e ≈ 1.6021766×10−19 C, which has been identified by…

then it will produce an accurate measurement. Materials: 1. Protractor 2. Ruler 3. Tape measure 4. Table or desk 5. Paper 6. Pencil 7. Masking tape Procedure: 1. Gather all of your materials 2. Clear off your table or desk 3. Place an object at one end of the desk (image A). Using masking tape, label this point C. 4. From the end of the desk opposite the object, estimate the distance to the object. Record your estimate 5. On the end opposite to the object, use masking tape and pencil to make…

After processing the data to find the mass of sodium bicarbonate as well as calculating the percent errors, standard deviation and etcetera, many trends and discussion topics arose and the data produced had small calculations. The percent error showed scattered results. When looking at the table, the percent errors can go from 7.05% to 200% and the reason for the extremely high percents were systematic errors made while measuring vinegar or other measurements. Two of the three deformities in…

Now move onto using 10mL volumetric pipette. Measure the temperature of the water again as before. In exact same way as before now pipette 10mL of water into 3 dry tubes and re-weight. Calculate the volume of water in each tube using 10mL volumetric pipette. Refer to practical – Chemistry Experiment 1 procedure by UniSA/Anthea Fudge, 2015, pages 149-158. Observations In this practical there are some thing happen which is after measuring the two sample my weight scale was not working.…

Office Spaces is updating their office chairs and have decided to alter the material and cross section of the arm supports. They have requested our assistance in evaluating several materials through experiments and simulations. The purpose of this experiment is to test these various materials and to recommend a material choice and cross section geometry that will minimize deflection of the arm supports. The following sections of this memorandum will detail several facets of the experiment.…
