Geology of the Earth and Planets 2002
An Activity rich exploration of planetary geology
With Paul Doherty, Modesto Tamez and John Lahr
Planets, orbits and rotation
Rectified Globe, Set up an earth globe with your location at top dead center and the north pole pointing to the north. The sunlight striking the globe is the same as the sunlight striking the earth.
The Annalemma, where the sun apears in the sky at noon each day.
The phases of the moon,
Dance of the Day and Year, act out the rotation and revolution of a planet.
Gravity Well, discover Kepler's laws in a gravity well.
Gravity Well explainer, feel the force versus distance in a gravity well model.
Gravitational Slingshot, A simple model
Earth Rotation, measure the length of a sidereal day.
Your weight on other worlds Explo website
freefall, punctured bottlemagnets repel on a stick
candle in a bottle
Playdough Moon, how big is the moon relative to earth?
Spin a koosh, planetary equatorial bulges
Planet shapes, the fundamental building blocks of planet shape.
Tide-o-matic, explore how tides are made.
Solar Thermal Measure the total energy output of the sun using a liquid crystal thermal postcard.
Solar Distance Measure the distance to the sun using a thermal postcard.
Solar Brightness Measure the brightness of the sun compared to a light bulb using a grease spot photometer.
How to safely view a partial solar eclipse
Montana squeeze box
Whose fault is it?
Tien's earthquake structure walls
Atmosphere and hydrosphere
Magnetic Atmosphere Model, stack magnets on a pencil to model the density of the atmosphere.
Boyle-ing water, boil water in a syringe by reducing pressure to Martian values.
Water Cycle Video, watch the video by Andre Zdravic and make a script for it.
Water Waves, measure them
Model of the earth's interior
egg/ clay model
Scale model of the earth. Eric.
Rotational angular momentum
Subway to subduction
PD magnet activities
Where's North?, hang magnets and they all hang in the same orientation.
Magnetic Poles, likes repel and unlikes attract, so why does the north pole of a magnet point north?
Magnetic Globe, explore the magnetic field of the earth.
Magnetic field of planets, images of planetary magnetic fields.
Magnetic Tape, use pieces of magnetic tape to model continental drift
Bits and bytes
magnetic sand in foam
Tien's clear can magnetization

Jello volcano: Will come from Modesto
Pillow lava chocolate: Wil come from Eric Muller
cooling fudge crystallization
polyurethane foam volcano
PD craters, drop steel ball bearings into salt to study impact craters.
Crater Illusion, change the lighting on a crater and make it look like a mound.
Icy bodies, use dry ice on warm water to make patterns like comets with tails.
Modesto's navigation brochure activity.
Coral's topographic mapping
Iron Science Teacher topographic map.
freefall balloon popper
Seeing IR with a digital camera
