6th Grade Engineering Technology

Homework


Rubric for technical drawing #2
Rubric for gear box #2

Mar 23-27: Reflection 6 due by first rotation next week. One reflection per partnership. Explain one or two problems you have encountered and how you solved them. Explain one thing that has gone well and how they have helped you with the project of making a gear box. Problems and solutions can include technical issues as well as teamwork issues. Final gear box and technical drawings are due by 3:20 on Thursday, April 2nd.

Mar 16-20: Reflection 5 due by first rotation next week. One reflection per partnership. Explain two or three problems you have encountered and how you solved them. Explain two or three things that have gone well and how they have helped you with the project of making a gear box. Problems and solutions can include technical issues as well as teamwork issues.

Mar 9-13: Reflection 4 due by first rotation next week. One reflection per partnership. Log into the wiki and post Reflection 4 about how your technical drawing went. Each person in the group needs to list at least two things they found challenging and how they overcame them. For example, finding the center of the circle that represented the gears may have been challenging for some students.

Note: All technical drawings of gears are due by 3:20 on Friday. If you take it from the classroom to finish, you must bring it back for credit.

Mar 2-6: Reflection 3 due at the end of the week (Friday at 3:20). You and your partner should brainstorm three different ways to observe/calculate/predict the mechanical advantage of speed you gain when using a gear box. This is NOT an internet research project. You may, however, talk with other groups.

Feb 23-27: This week we finished up our trial gear boxes with the following criteria:
  • Two differently sized gears in alignment
  • Each gear on an axle supported by bearings
  • Gears must mesh continuously and smoothly
  • Gears must rotate freely with the axle (one for one rotation)
  • Each gear must have a handle attached to it

  • By your first rotation next week, log into the wiki and post Reflection 2 about how your investigation has been going. Explain two or three problems you have encountered and how you solved them. Explain two or three things that have gone well and how they have helped you with the project of making a gear box. Problems and solutions can include technical issues as well as teamwork issues.

Feb 9-13: By your first rotation after the break, log into the wiki. Make a page under the appropriate class for yourself and your partner(s). Post a reflection about how your investigation has been going. Explain two or three problems you have encountered and how you solved them. Explain two or three things that have gone well and how they have helped you with the project of making a gear box. Problems and solutions can include technical issues as well as teamwork issues. Label this Reflection 1.

Jan 26-30: None
