Activity:
Today should be the last day you work on your compound machine. Finalize the build and test your compound machines by measuring the force required to operate your machine and lift the weight. This data will be needed to determine your AMA.
HW:
Report for your Compound Machine is due Wednesday.
Activity:
Finalize your Compound Machines
Groups will present their compound machine by simply demonstrating the function of your machine. Be prepared to discuss the overall IMA, AMA, and Efficiency of your compound machine. You do NOT need to created a slides presentation, just make sure your IMA, AMA, and Efficiency values are calculated and ready to share with the class.
Disassemble your machine and return VEX parts to the cabinet.

HW:
ACTIVITY:
Discuss electric circuits using 1.2.3 Intro to Electricity Presentation
Begin Activity 1.2.3 Electrical Circuits – Simulation.
Take pictures of your circuit schematics and insert them into the document with your answers. Everyone must create their own copy. Put all answers in your notebook.
You can review the presentation under the resources entitled "Introduction to Electricity" to help you with some of the calculations.
Turn your work in to google classroom when finished.
HW:
ACTIVITY:
Review the simulation from yesterday and discuss the conclusions about how series and parallel circuits are the same/different. Demonstrate with the class the different simulation scenarios to ensure all understand.

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:
ACTIVITY:
If time permits, begin building your winch using the following the instructions in the activity to build the winch.
HW:
ACTIVITY:
Begin building your winch using the following the instructions in the activity to build the winch.
If time permits, begin Activity 1.2.5 Mechanical System Efficiency
HW:
Quiz on Series and Parallel Circuits(Ohm's Law and Kirchoff's Law) tomorrow.
ACTIVITY:
If time permits, modify your mechanical winch so that the weight is lifted with a compound gear train rather than a simple gear train. Perform the same tests, and compare the efficiency of the two systems. Activity 1.2.5 Mechanical System Efficiency.
Review Mechanical System Efficiency results and compare the two gear train systems.
HW:
Submit your completed activity sheet to Classroom
Activity:
Review Mechanical System Efficiency results and compare gear train vs chain and sprocket
Build the winch that we'll use for Activity 1.2.6 Maximizing Motor Power. Follow the build instructions in this document
Begin Activity 1.2.6 Maximizing Motor Power and build the structure shown in procedure 7. 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.
Review slides 9-14 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.
