Learning Tasks: Complete these learning tasks using both the K’NEX Oscillating Fan SCE on the computer, the K’NEX model, and the K’NEX Interface. (Teacher Note: Encourage students to complete these learning tasks using the K’NEX Oscillating Fan SCE before they program the computer to operate the model with the K’NEX Computer Control Interface.) Program the Oscillating Fan model so that it will operate automatically to cool a room and keep people comfortable. 1. * Write a program that makes the model 3. * Edit the program so the LED shines green oscillate (slow the oscillation motor to 20% while the fan is spinning. power) as the blades spin when the push (Science and Technology) button is pressed. (Science and Technology) 2. * Edit the program to stop the fan when the push button is pressed a second time. Include a loop in the program so that the fan can be turned on and off over and over again. (Science and Technology)

Challenge Activities: As you move through the Challenge Activities listed below, you may have to change the location of some of the components or add additional components to the K’NEX Interface. Part of the learning process is understanding when, where and how to make those changes. 1. * Complete some research related to fans before continuing with the project. Use the following questions to guide your research and report all of your findings in your STEM Journal.

3. ** Determine the average number of times the blades turn in one minute. Express this number as a speed with proper units. Run four trials as you collect your data. Present your data in a table and calculate the average speed of the fan blades. (Science and Mathematics)

a. What is the purpose of a fan? b. What are the different parts of a fan?

4. ** Redesign the blades to move air as they spin. Cover the blades of the fan using paper and tape. Run the fan to see if you can feel air moving in front of the blades or behind the blades. If not, redesign the blades so that a breeze is produced in front of the blades as the fan runs. Experiment to see if further design changes will produce a stronger breeze. (Science, Technology, Engineering)

c. What are some of the different types of fans? d. Why do you feel cool when a fan blows air over your skin? (Teacher Note: Student performance on this Challenge Activity will be partially dependent on the grade and ability level of your students. Assess students accordingly.) (Science, Technology, and Engineering) 2. * Determine the speed of the K’NEX Oscillating Fan’s blades in revolutions per minute (rpm). In other words, how many times do the blades spin in one minute? (Science and Mathematics)

16

5. ** Change the gear ratio of the model and report the effect on the operation of the fan. Determine the gear ratio of the gear system on the fan. Switch the red and blue gears on the model. Does the fan operate differently when you run it after the blades have been changed? Describe the difference in operation. Determine the speed of the blades with the new gear configuration (four trials and a computed average). Is the fan now geared up or geared down? Support your answer with data from the experiment

you just completed and your findings in Challenge Activity number three (3) above. (Science, Technology, Engineering and Mathematics)

8. ** Prepare a bill for the cost of the project that will be given to the manufacturing company owners.

Second, include the cost of labor required to design and build the K’NEX Oscillating Fan. The fan project will require that two employees work for 24 hours each on the actual design of the fan. These designers each make $150 per hour. Two builders will construct the fan in three hours. The builders each make $28.00 per hour.

7. * Refer to the building instructions for the K’NEX Oscillating Fan and the Cost per Piece Chart provided by your teacher. Determine the cost of the materials that are used to build the K’NEX Oscillating Fan.

Third, include the cost of labor required to develop the software program that will operate the fan. One programmer will work for 10 hours to program the fan to operate efficiently and safely. The programmer makes $125.00 per hour.

a. Make a data chart for this activity in your STEM Journal and include all of your calculations b. Place your answer on the board in the spot indicated by your teacher. (Teacher Note: Set aside space on the white board or chalk board for each team to list their cost of materials so that the costs are visible to the entire class.).

Fourth, add up all of the costs associated with the project and include a profit for your company that is 35% higher than the total of the other four costs. Prepare a bill for the project that includes all of the costs with 35% added to each of the categories. (Teacher Note: This is an excellent opportunity for students to design a name and logo for their company. With those in hand, the students can prepare an official invoice to submit to their customer.) (Technology, Engineering, and Mathematics)

c. How do your results compare with other groups who have completed the challenge? If answers vary, devise and implement a plan to check your work. (Teacher Note: Provide time for the teams to compare their answers and to correct any differences. The Cost Per Piece Chart has been provided in an editable format allowing you to assign costs to the K’NEX pieces that are appropriate for the students you are working with. Use the same costs for all 5 lessons. This is an excellent project to complete with spreadsheet software if students have experience with spreadsheets. Students can design data charts, enter formulas, and compute both the cost per each type of piece and the total cost of the pieces used in the project. If the students designed a spreadsheet to compute the cost of materials in Lesson 2 they should be able to add a column to that spreadsheet to compute the material costs for the K’NEX Oscillating Fan.)
