Oct 10, 2012 · _________________________________ Signature Osmosis & Diffusion Post Lab Questions 1. Construct a xy scatter plot of the average percent change in mass for all of the class data in each solution. Your graph should only have six points. You do not need to add error bars nor do you need to add a trend line.
experiment date(s): 1 Experiment 1 - Density of Liquids and Solids Goal: To accurately determine the density of an unknown liquid and an unknown solid. Density = mass units are: g or g where 1 mL = 1 cm3 volume mL cm3 To properly measure density, we need a container whose volume is known to a high degree of accuracy.
Record the volume in Table 1. 14. Add one egg to each beaker and cover with foil. 15. Let the eggs sit for 24 hours. In the meantime, develop a hypothesis stating how you believe each egg will be affected by the solution in the beaker over the 24 hour period. Record your hypothesis in the Post-Lab Questions section. 16.
Step 1: Clearly state the scientific concept (PreLab question #1) and information about the scientific concept related specifically to this lab. Step 2: Write how achievement of the main objectives of the lab (PreLab questions #2, #3) helped you learn about the scientific concept of the lab.
In this experiment, two electrically connected payloads with a variety of plasma instruments measured effects associated with operation of a 1 keV, 40 mA electron gun and a 450-volt dc power supply. During electron beam operations, it was found that both mother and daughter payloads reached high positive potentials as a consequence of the ...
Post-Lab Questions Experiment 1: Waves 1. Describe how the speed of the waves were affected by changing the amplitude and frequency 1. Table 1: Slinky Measurements slinky Mass (kE Number of Length (m) Loops 2. 2. Compare the speed of the longitudinal waves to the speed of the transverse waves.
discussions. You should ask questions in or out of class. You should also try to participate in the actual lab work (and not simply allow your lab partners to do things for you). The more effort you put into the course work, the more you will learn. The class is an opportunity to learn valuable skills; take full advantage of it!
Experiment 1: Coding Post-Lab Questions 1. Using the red, blue, yellow and green beads, devise and lay out a three color code (or codon) for each of the following letters (codon). For example Z = green : red : green. ...
