ACTIVITY:
Mr. Tackett is out today after the robotics competition
Complete the assignment in Classroom, "Should I build useless things?"
HW:
ACTIVITY:
Discuss breadboarding presentation and the proper use of a multimeter, stripping wire, and making simple circuit connections.
HW:
Quiz on Series and Parallel Circuits(Ohm's Law and Kirchoff's Law) tomorrow.
ACTIVITY:
Quiz on Series and Parallel Circuits(Ohm's Law and Kirchoff's Law)
HW:
ACTIVITY:
If time, log in to your PLTW account and go to Activity 1.2.5 Mechanical System Efficiency VEX V5. Open the link to "Gearbox Motor Winch Construction Guide", and build the winch according to the instructions.
If time, begin the activity.
HW:
ACTIVITY:
Discuss Work, Energy, and Power presentation.
Log in to your PLTW account and go to Activity 1.2.5 Mechanical System Efficiency VEX V5. Open the link to "Gearbox Motor Winch Construction Guide", and build the winch according to the instructions.
Once your gearbox is fully assembled, begin the activity.
If time permits, modify your mechanical winch so that the weight is lifted with a simple gear train rather than a direct drive system. Perform the same tests, and compare the efficiency of the two systems.
Review Mechanical System Efficiency results and compare the two gear train systems.
HW:
Submit your completed activity sheet to Classroom
ACTIVITY:
In my absence, complete Activity 1.2.1 Energy Sources Presentation.
Review the attached Slides and then create a Slides presentation of your own about a type of energy source of your choosing. Review the document and following the instructions for what to include in your presentation.
HW:
Submit your completed activity sheet to Classroom
Activity:
Activity 1.2.5 Mechanical System Efficiency (SIM). Follow instructions in PLTW.
Review answers as a class once finished.
HW:
ACTIVITY:
Review Work, Energy, and Power presentation.

Activity:
Time for students to catch up on missed work.
HW:
Activity:
We'll use the same winch we built for Activity 1.2.5 for Activity 1.2.6 Maximizing Motor Power.
Log in to PLTW and begin Activity 1.2.6 Maximizing Motor Power. You will replace the gears in the winch with 2 large wheels as shown in the picture.
Complete procedures 1-9 to measure all the specs you need to characterize your motor.
HW:
Activity:
Review and wrap-up Activity 1.2.6 Maximizing Motor Power.
Review slides from Activity 1.2.6 Maximum Motor Power Presentation. Review how to calculate an ideal gear ratio that allows the motor to deliver max power.
Complete the Motor Power Spreadsheet to create your motors power curve. Enter the values you obtained for your motor into the yellow highlighted sections of the spreadsheet.
Finish testing your motor and answering all the questions in Activity 1.2.6 Maximizing Motor Power. Submit your completed worksheet, conclusion questions, and completed spreadsheet embedded in your Doc to Google Classroom.
Review Activity 1.3.1 Solar Hydrogen Fuel Cell System and build the Solar/Fuel Cell car build instructions.
For reference, Fuel Cell User Guide
HW:
ACTIVITY:
Review Fuel Cell User Guide. Show students how to connect solar/fuel cells in series and parallel.
Once students understand how to use the Fuel Cell and Solar Panel, begin designing and planning for the Solar/Fuel Cell Race Car Activity
