Build Your Own Planet
by Daniel D. Slosberg
This unit is about stars and planets, and especially about
planetary crusts, they makeup and transformation.
I started with two days on asterisms and how to read a star
chart which was done in conjunction with a Greek unit
the team was doing.
Then we spent three days researching planets to learn
about the planets, how to do research, and how to write
reports.
The plans for the rest of the unit involve learning about
density, learning about volcanism through comparison
with other planets, and a culminating report in which the
students build a planet of their own with its own
planetary crust and have to justify the decisions that they
made and how it works together.
Asterisms
The students studied Greek mythology for a few weeks in English and
that culminated in a Greek Day celebration of which this was a part.
I created a star chart for this using ArcView which I learned in my
Urban Planning class. This sub-unit consisted of several lessons:
• journal entries written by the students before each class period
• a lesson on how to read star charts
• a half page write-up on the myth behind an asterism they research
• a one page essay creating a myth for one or two asterisms that they
create themselves on a blank star chart and
• a star party in which to view the asterisms they learned about and
those they created.
Planetary Research
This was a few day sub-unit on what other planets are like. This subunit consisted of several lessons:
• journal entries written by the students before each class
• an interactive lecture which seems to just be pulling together the
students knowledge of Earth, but also goes through units and their
importance, how to do unit conversions, what I expect on
worksheets (i.e. change them if you don't like them!), and my
expectations in general
• a time for them to research their planets
• a GeoSafari game to keep them fresh on the relative positions of all
the planets as well as what a comet looks like, where the asteroid
belt is, and the sun and culminated in
• a jeopardy game for which they had to pool all their information
together in groups.
Funny Water
This is a five day sub-unit about density. It comes from my Science
Methods Standards book, pp150-3. It is important that the students
have a clear understanding of what density is to understand why
iron sinks to the center of the Earth and creates the Earth's magnetic
field, and why the plates don't sink, and another reason it makes
sense for glacier's to be on top of rock. This sub-unit consisted of
several lessons:
• Of course I will have a journal as I do for all my sub-units:
• Demonstration of Liquids of Differing Density
• Lab Comparing Liquids of Differing Density
• Lab Comparing Objects of Different Densities
• Lab Comparing Objects of the Same Density but Different Sizes and
• A Day to Finish Writing the Lab Report.
Researching a Crust
A good way for students to learn about volcanoes,
earthquakes, and glaciers, is to put them in
context with all the planets and moons in the
solar system. There are many parts to this two
week sub-unit as well.
• Journal
• Lectures on Volcanoes, Earthquakes, and
Glaciers and
• Research of a Planet or Moon of the Student’s
Choice.
Build Your Own World
This is the culminating part of the unit. Students
have learned about planetary crusts, how the
planets are internally and externally heated, and
how different layers work together. Now they
have to put all these concepts together and build
a planet, justify what sort of tectonics may be
there.
• There will be journals,
• And students will have to create their planets.
