How the Core Problem is Introduced? We have an open discussion on the first full day
about the core problem.
What would an announcement of the discovery of alien life include?
Students give examples.

Re-education We’ll spend a lot of time informing them away from
their initial ideas
“Why is it every UFO sighting begins with ‘So me and Roy was down in the bog, fishin’…’” --Woody Allen
If only we had large numbers of trained people, all over the world, watching the skies every night so they could make note of UFOs. Oh, wait, we do! They’re called Amateur Astronomers, and guess what? They never see UFOs.” Neil DeGrasse Tyson

How did the Physics & Astronomy Class Help the Campers Develop a Plausible Solution to the Core Problem?
ExxonMobil Bernard Harris Summer Science

We want the students to have the freedom to emphasize in their final project the aspects of the camp they find most interesting. This could be Physics & Astronomy, Rocketry, Biology, Robotics…

Goals of Physics & Astronomy Class:

Camp
•Develop a Cosmic Perspective.
•What exactly does the solar system
look like?
•What would a scale model look like?
•How do Rockets work (we cover
this in Engineering as well).
•What are Newton’s laws?

Side notes about the activity. Is this how you thought the relative sizes of the planets
looked?
In the context of this activity, what do you think about the energy problem we have?

A scale model of the solar system that incorporates relative distance We want to build a model of the solar
system that scales the distance between the planets rather than the relative sizes of the planets.
After setting up the model, campers get index cards telling the distance to a planet and we set up the solar system outside with students standing where the planets go.

On this scale the Earth is ¼ inch from the Earth and it took Apollo 11 4 days to cover the distance.
How long would it take to get to Saturn at a speed of 1000mph?
New Horizons is going 40,000mph

Sometimes we lay out this activity on a football field (if it is an evening activity), otherwise we do it outside the physics building.
How did Engineering Class help the campers develop a solution to the core problem?
In engineering the students built and launched rockets and learned about how they work.
They Built Paper rockets, straw rockets, and model rockets.
We studied rockets in physics and we saw real rocket parts (and scale models) at the Stafford Air and Space Center.

Assume a one pound payload has to be put into orbit at 100 miles above Earth’s surface .
The payload needs to be going very fast to stay in orbit
Assume one pound of fuel will make a one pound payload got “very fast.”
Assume it takes one pound of fuel to raise one pound of payload 10 miles
How many pounds of fuel do you need to start with?
Why do Rockets look the way they do?

Campers are required to build a robot that travels a certain distance then turn, then travel another distance then turn.
No practice runs are allowed, so the students have to measure the circumference of the wheels so they know how many rotations to have the wheels make.

Camps
• Using 20 assorted pieces
build any object.
• Write instructions on how
to build it.
• Hand the instructions to
another group.
• They have to build your
object without
seeing it
• Cost~$50
Paper Rockets Build a rocket out of one
sheet of paper, an index card, and scotch tape.
Launch the rocket using the homemade paper rocket launcher.
Explore the function of the parts of the rocket by modifying and retrying.
Cost ~$50 Bernard Harris - Exxon Mobile Summer Science

Straw Rockets Straw Rocket launcher
allows repeatable “thrust”
Allows angle adjustment.
Only supplies are straws, tape, and index cards.
Cost ~$170.
