Each unit in this Hands-On / Virtual workshop ends with a discussion
page. The questions we ask here serve two important purposes.
First, they help your group reflect on the concepts that you have studied
in this unit, summarize what you have learned, and encourage you to connect
those concepts to other things you experience in the world. Secondly,
they are the means by which the remote instructors of the class get immediate
feedback on how much the group is thinking and learning. They are
the immediate unit assessment.
You are asked as a group to discuss at least 2 of the
following questions. We encourage you to discuss them all, but we
ask for an email commentary to only two of them. Before you start please
see this page for some guidance
on what types of discussion we are looking for. After you email your
discussion, you can expect (within a day or two)
an email from us commenting on
what you wrote.
Sometimes this commentary will ask for further discussion; sometimes
it will give examples of what other groups had to say. You should
always read these commentaries carefully, because they are intended
to guide you to a better understanding of the subject matter.
Here are some things to do to finish this section.
What question did you think of that could be studied, or observation could you make
that is interesting or unexpected? Send it to the
Question
board!
Discuss these questions with the people in your group.
Please
send us a discussion of these three questions. Don't forget to tell us the
group name.

not work, or causes the wrong email program to be started.

My friend Bob wants to remove the water from his boat
that splashed in when he hooked a fish. He has a hose which
he is considering using to siphon the water out. Unfortunately,
he doesn't know anything about siphons. Please explain how to
get the hose working as a siphon, and discuss the relative
merits of using a siphon versus bailing with his hat.
Filling a backyard swimming pool is a slow business! My neighbor Margie says you
should use the hose nozzle, set to make a jet of water that will reach all the
way across the back yard, because this will speed the process up. Louise says
this won't help at all. Please discuss Margie's idea, and explain who is right.
Explain what happens when you flush a toilet. We will assume
that the tank starts out filled, and not consider how it gets
refilled later. But we are interested in
all the things that happen to the water level in the bowl, and why
it goes "glurk!" at one point.
If there is something that you don't understand about flowing fluids,
Ask us!
This is the end of this unit.
