Completed a virtual lab putting study to practice with a wave simulation. To conclude the lesson Anna started a virtual Escape Room which reinforced the concepts learned in the wave unit and applied crosscutting concepts from the SEPs.

Topics practiced in this session:
Wave characteristics, wave interference, standing waves, beats and interference of sound waves, & Doppler effect

Anna reviewed coursework from 5/10/21 and was introduced to a virtual circuits lab. The lab was shared via Google Docs. It covers and reinforces these learning goals: Part 1 - Comparing parallel and series circuits; Part 2 - A PhET simulation exploring circuit construction; Part 3 - Measuring current and voltage

We covered Ohm's Law and Kirchhoff's junction and loop rules. We also reviewed series/parallel circuits and resistors. Anna scored an 89% on the DC Circuits unit assessment.

I started the lesson with Anna by explaining the differences between series and parallel circuits and giving her the formulas for finding the total resistance in each type of circuit. I told her to view a video by Khan Academy on parallel circuits and then I showed her how to obtain the correct answers to several of the problems in her workbook. There was no assignment. This was my last class with Anna as I have limitations on my time that preclude my expanding my hours to meet her time requirements.

I started the lesson instructing Anna to watch a short Khan Academy video about the placement of ammeters and voltmeters on a circuit with resistors. I followed the video by asking her questions from p. 253 concerning placements of ammeters and voltmeters. I then asked her questions from p.254 through p.256 about voltage changes in series circuits. There was no assignment.

I worked with Anna to help her fully understand the relationships of the acceleration, velocity, and position vs time graphs. I then instructed her to watch a video about free body diagrams for forces such as the ones we have studied in this chapter dealing with electic forces. After that, I gave her a reading assignment and a written one on part A of p.245.

I reviewed with Anna the ratio of charges of two joined particles to obtain rotational equilibrium from a third charge. I also directed her to view two videos to explain charge quantization and how grains of pollen could have different repulsion forces. Lastly, we studied an acceleration vs time chart to find how charges move with electric repulsion. The homework was to construct two charts: velocity vs time and position vs time based on the chart on p. 243.

I worked with Anna to calculate the different charges on two point sources connected by a rigid, non-connecting rod. At the beginning of the class, I told her to view a video which developed Coulomb's equation and then I worked with her to analyze a diagram of three forces. The forces had to be in equilibrium in the scenario and so the farther point from a third point had to have a larger charge compared to the point closest to the third charge. At the end of the session, Anna was still developing her analysis of the diagram. I assigned her to study the scenario and try to develop answers to questions the activity asked.

I asked Anna a number of questions from her studies of forces on points in space. We used Coulombs law to discuss both quantitative and qualitative effects of charges in space on each other. We did problems involving both electromagnetic and gravitational forces in such a way as to show how both sets of laws use the inverse square of the distance between point sources. There was no assignment.
