HP Cycle 35

🟢 6: W 4/14, 🔵 8: Th 4/15 electroscope lab observations

Today, we will try to describe what is happening when we operate a gold leaf electroscope.

Watch the following video and record your observations on the Electrostatics Lab hand-out. See the example for #1 for how to record your observations. Upload pictures of your observations to ✅ GoFormative "LAB Electroscope".

If you finish early, start watching homework videos.

Homework: Submit your observations in ✅ GoFormative by Friday at 10pm. Please watch the following videos. Make a good effort to understand these videos.

🟩 6: Th 4/15, 🟦 8: F 4/16 charging

Today, please review the videos that had been posted previously about charging. (See previous post.) Today, you will visualize and draw where excess positive and negative charges appear while charging an object. If you finish early, move on to the next lesson.

Homework: Enter your answers in ✅ GoFormative "Electrostatics Charging Worksheet (PH)" by Sunday at 10pm.

💚 6: M 4/19, 💙 8: M 4/19 electroscope charges

Today, based on the what we've learned about charging in the last two classes, we will attempt to explain what is happening inside the electroscope during the Electrostatics Lab in ✅ GoFormative. Try to draw excess charge by drawing positive and negative signs in your Electrostatics Lab and annotate with new vocabulary. (Let's assume that plastic becomes negative and acetate becomes positive for uniformity.) For example, here's what I'd expect to see for number 1.

If there are no positive and negative signs, that does not mean that there aren't any positive or negative charges in that location (of course you know there will be protons and electrons there), but rather it just means that there are an equal number of those positive and negative charges. Add you charges and annotations to ✅ GoFormative "LAB Electroscope". Check the resource below for more explanations.
