First Day of School
Electrolysis in the classroom
The Night Thoreau Spent in Jail
The first day of school can be a terrific challenge.
Establishing rapport is one of the initial goals. The following exercise facilitates the process:
Lesson Objectives:
- Students will get to know me
- Students will demonstrate their ability to reflect upon themselves
and their accomplishments by writing
on the very first day
- I will learn something interesting/memorable about my students
Grade level and subject area:
7-12/All
Activities and strategies:
- I introduce myself.
- I discuss some of my highs and lows (dreams and disappointments)
while referring to my posted copy of the sheet (see above).
- I ask students to think of some of their own disappointments and rewards and to
write them down on a sheet like the image above.
- Students look over their papers,
thinking of the stories behind each of the things they've written.
- I tell three stories of my own:
- a) (1-2 minutes) A story about something funny that happened to me.
- b) (15-30 seconds) A story about something I know nothing about. This
shows that we can't speak about something we don't know about.
- c) (1-2 minutes) I tell a story about something that happened when I was a child.
- Students write a story about a topic that they know well.

Electrolysis in the classroom

Lesson objective:
Students will be able to
demonstrate the process of electrolysis using common, household items.
Materials:
- 1 Nine-volt battery
- 1 Empty 35mm plastic film case with lid
- 1 Nine-volt battery clip with leads
- 2 Alligator clips attached to the leads
- 2 Small pencils with both ends sharpened
- 1 Acetate sheet, waxed paper, or petri dish
- 2 Drops of blue food coloring
Procedure:
- Place the 9-volt battery in the empty 35mm film case.
- Make two small holes in the lid of the case for the battery clip wires to go through.
- Connect the battery clip to the battery and replace the plastic lid.
- On an acetate sheet, piece of waxed paper, or petri dish, place several
drops of water (A petri dish filled with water works well, if
placed on an overhead projector. More students can observe).
- Connect the alligator clips to one end of each pencil. Make sure both ends of
the pencils are sharpened to a fine point.
- Place the other sharpened ends of the pencils in the water.
Bubbles of gas may come from the ends of the pencils in the water. These are
bubbles of oxygen gas and hydrogen gas.
- Place a sheet of white paper under the acetate sheet
- Place 20 drops of water on the acetate sheet. Dissolve several crystals of
table salt (sodium chloride) in the water. A toothpick may be used to mix the salt in the water.
- Place two drops of blue food coloring in the salt solution and mix.
- Place the two sharpened ends of the pencil in the solution.
- Gas bubbles form at
the end of one of the pencils which causes the blue food coloring to fade and
finally become colorless. This is chlorine gas. After a short period, one can
detect the aroma of the gas.
An electrolysis apparatus from a supply company may cost about
$100. It may require thirty volts of electricity and the students must watch
while the instructor performs the experiment. The procedure above is an inexpensive
way to show the process. The equipment costs about $1.35, and the students get to
do the work!

The Night Thoreau Spent in Jail
This multi-faceted activity examines the idea of civil disobedience and
the notion of personal responsibility vs. government control. Students of all
abilities, in grades 10-12, enjoy the readings and learn a lot from the projects.
The readings include The Night Thoreau Spent in Jail, a play by
Jerome Lawrence, an excerpt from Annie Dillard's
The Pilgrim of Tinker Creek, and a newspaper article about a local political
activist. Students also read the essay "On the Duty of Civil Disobedience" and
selections from Walden, both by Henry David Thoreau. The students learn
Thoreau's views on: education, conformity, the war with Mexico, slavery, the duty
of a citizen, nature and the environment; what the Walden experiment was, and why
he went there. They also reflect on the readings, write in journals, and share
their insights with classmates.
Over two nights, students read the play and then discuss it during class.
During the next few days, students read the related articles and excerpts.
Then, they explain the connections between these works and those of Thoreau, in a paper.
The major assignment for this unit is a collaborative effort in which small groups of
students prepare scripts for a trial of Thoreau. Each script must include roles for
the prosecutor, the defense attorney, the judge, Thoreau, and the witnesses. The
remaining class members serve as the jury. Students hand in the script and then
perform a play, based on the script. Historical accuracy and oral presentation
skills serve as the basis for student s evaluations.
In creating the script, students select one of three cases against Thoreau:
- Thoreau has been arrested and charged by the State of Massachusetts
for tax evasion. The state accuses him of failing to pay hi
s poll tax.
- Thoreau has been arrested and charged with violation of the Fugitive Slave
Law in the Henry Williams Case. Thoreau is accused of aiding and abetting Williams,
in the slave's attempted escape to Canada.
- Thoreau, school master in the Concord Public Schools is charged with
insubordination and violating the constitutional
separation of church and state by permitting his students to discuss theological
questions in his classes. The Concord Board of Education seeks Mr. Thoreau's dismissal.
Students like The Night Thoreau Spent in Jail because the issue of civil disobedience
is relevant to them. Also, in "On the Duty of Civil Disobedience" students like
Thoreau's display of compassion toward his cellmate and the assertive style of
Emerson's wife when she tells Emerson, in the student s own words,
"Take a chill pill and get real." This activity gives students a sense of this
historical period and shows them how the pressing issues that existed then, still
exist today.
