Activity 1: If the cups are ranked from most Splenda to least
Splenda, cup “D” should be ranked second. Activity 2: When the
red lead is hooked to the top of the stiff wire, the compasses
should move to look like picture 2. However, many people’s stiff
wires became magnetized in transit and even with the current
flowing through the wire, the compasses looked like either
picture 1 or picture 4. With no technical problems such as that,
picture 2 would be the correct answer. Activity 3: This activity
had by far the most technical difficulties. If all the equipment
worked correctly, then when the magnet was dropped north side
first with the tube held vertically, then the red LED should
have lit up. However, more than one person had a malfunctioning
red LED and would have seen nothing. Activity 4: The 2nd and 3rd
set ups caused the pinwheel to spin counterclockwise when
looking down from the top. PhysicsQuest 2008 Winners Announced!
