Day Sixty One Overview

Day Sixty One Overview

- began class by asking the students to describe in their own words why a dryer sheet ends up stuck to the clothes in the laundry
- I then showed the students a demonstration where a used static electricity to make a balloon bend a stream of water without touching the stream of water
     - the students were asked to explain the demonstration using a picture
    - I made a model on the front board that the students were asked to check against theirs
    - most students needed to add electrons to their drawing
- I then played a short audio clip that explained why dryer sheets end up stuck to clothes instead of the clothes being stuck together
- I stressed to the students that opposite charges attract and like charges repel
- the students also visualized examples of the three ways that something can become charged
     - friction - when electrons are wiped from one object to another
     - conduction - when electrons move from one object to another through direct contact
     - induction - when electrons can arrange charges on another object without direct contact
