Edgenuity Project: Tech Design Process STUDENT WORKSHEET

Total points will vary depending on whether the prototype/model was redesigned and retested.

Complete the worksheet as you go through the technological design process.

1. Describe the problem.
2. Record related information from your research. List the sources that you used. 3. Establish criteria, and list criteria in order of importance.
4. Identify possible solutions.
5. Draw prototypes/models in the space below when necessary.
6. Evaluate solutions using the criteria, and choose the best solution.
7. Explain tradeoffs you had to make, if any, to choose the best solution.
8. Record the results of the prototype/model test.
9. Draw the redesigned prototype/model in the space below.
10. Record the results of the test.

The particle in a two-dimensional well is a useful model for the motion of electrons around the indole ring (3), the conjugated cycle found in the side chain of tryptophan. we may regard indole as a rectangle with sides of length 280 pm and 450 pm, with 10 electrons in the conjugated p system. as in case study 9.1, we assume that in the ground state of the molecule each quantized level is occupied by two electrons. (a) calculate the energy of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels. 9.27 electrons around the porphine ring (4), the conjugated macrocycle that forms the structural basis of the heme group and the chlorophylls. we may treat the group as a circular ring of radius 440 pm, with 20 electrons in the conjugated system moving along the perimeter of the ring. as in exercise 9.26, assume that in the ground state of the molecule quantized each level is occupied by two electrons. (a) calculate the energy and angular momentum of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels.
