On the fence
• What do you know?
THEMIS
• – Time History of Events and Macroscale Interactions during Substorms
• Video of THEMIS http://ds9.ssl.berkeley.edu/themis/flash.html
The Sun
• Electromagnetic Field
Mapping magnetic fields
• You should have:
• 1 large piece of paper
• 1 cow magnet
• 2-3 compasses
• Writing implement

Procedure

• Place the compass on the middle of the paper and trace around it. Draw a dot somewhere near the magnet and place the center of the compass over the dot.
Mapping magnetic fields

Procedure

• Place the compass on the middle of the paper and trace around it. Draw a dot somewhere near the magnet and place the center of the compass over the dot.
• Draw a dot at eh location of the arrow head of the compass needle
• Move the compass from the paper and draw lines connecting the dots with arrows indicating the direction that the compass points.
• Remove the compass from the paper and draw lines connecting the dots with arrows indicating the direction that the compass points.
• Continue steps b-d until the line meets the magnet or edge of the paper
• Pick another spot near the magnet and repeat the processes.

CLUSTer
• The four Cluster spacecraft are providing a detailed three-dimensional map of the magnetosphere, with surprising results
• http://sci.esa.int/science-e/www/area/index.cfm?fareaid=8
• How much do you get?
• On you paper number 1-5- skipping 2 lines between each.
• Observe each bag and write down your observations.
• Which bag has the lightest color beads?
• Which bag has the darkest color beads?
• Why do you think there is a difference?
• Looking at the bag with the sun glasses covering them and the regular glasses. What is the difference?
TIMED
• A Mission to Explore One of the Last Frontiers in Earth’ Atmosphere
• The TIMED (Thermosphere Ionosphere Mesosphere Energetics and Dynamics) mission is studying the influences of the Sun and humans on the least explored and understood region of Earth's atmosphere - the Mesosphere and Lower Thermosphere/Ionosphere (MLTI).

In our solar system
• Impact craters
• Cake Batter Lava
• Moon Phases
• Climate Cycles
• Let’s make a cloud.
• It’s Alive
Impact crater
• Look at the photographs of the Moon, how do you think the craters were formed?
• What do you think are factors that affect the appearance and size of craters and ejecta?
• What does this “lunar” surface look like before testing?
• Measure the mass of the first impactor and record it on your Data Chart.
• Drop impactor #1 from a height of 30 cm.
• Measure the diameter and depth of the resulting crater. Count the rays, measure, and determine the average length of all the rays.
• Record the information on the Data Chart and repeat the procedure varying the drop height as instructed on the Data Chart
Impact craters
• What does the data reveal about the relationship between crater size and velocity of impactor?
• What does the data reveal about the relationship between ejecta (ray) length and velocity of impactor?
• If the impactor were dropped from 6 meters, would the crater be larger or smaller? How much larger or smaller? (Note: the velocity of the impactor would be 1,084 cm/s)
Moon Phases - oreo
• Materials:
• 4 Oreos
• 1 plastic spoon
• 1 paper plate
• Oreo handout
• Make the Oreos look like the handout and place them on the paper plate.

AIM – aeronomy of Ice in the Mesosphere
• Exploring clouds at the edge of space

New Horizon
• New Horizons is on its way to Pluto, which it should reach it in 2015.
