We build Activity 1 of Section 2 during this session and also start a discussion on series and parallel circuits, which is a main them of Section 2.
In this session, we learn how batteries behave when placed in series and in parallel with each other.
Homework: Try Activities 2 and 3 on your own.
In this session, we learn more about batteries and then build Activities 4 and 5 as we learn about LEDs in series and parallel circuits.
Homework: Rebuild Activities 4 and 5 on your own.
In this session we learn more about working with wire and how circuits are protected by fuses and circuit breakers. We also cover more details regarding schematics.
We build the red light / green light game (Activity 6) during this session. We also discuss an introduction to electromagnetism.
We continue our discussion on coil kickback and learn how to protect components using a diode. We then begin a detailed discussion on resistors.
In this class, we learn more about resistors and how they behave in parallel and serial. We also built activities 6, 7, and 8.
In this class, we review the concepts of series and parallel resistors and then move on to capacitor in parallel. When then begin a discussion digging into more details on capacitors.
Homework: Build Activity 11, add more capacitors to Activities 10 & 11 and observe how long the LED remains lit after disconnecting the battery.
Also practice previous activities during the break.
In this class, we continue our discussion on capacitors. We then built Activity 12 and start our discussion on diodes.
Homework: Build Activity 11 (if you haven't already) Build Activity 12 by following the schematic (not the breadboard picture.)
In this class we learn about voltage drop and Kirchhoff's Voltage Law. We then learn more about diodes and LEDs.
This class provides a deep dive on Ohm's law and how to use it when deciding the value for current limiting resistors.
Homework: Build Activity 13 and complete problems in Activity 14.
In this class, we wrap up the discussion on Ohm's law and discuss the Activity 13 circuit. We then begin going through the Section 2 review quiz.
Homework: Complete the Section 2 review quiz, which is available with the buttons above the videos.
