Pipehenge

=**Welcome to Pipehenge**=

You may have noticed children climbing on a strange object on our playground. In addition to being the source of hours of fun, That strange object is also a scientific tool. Pipehenge is a tool that can help measurement daily, nightly and seasonal changes in our sky. Pipehenge Projects

 * Pipehenge Lesson #2: Using the Compass Points**


 * Learning Goals
 * Identify location and purpose of compass points
 * Use compass points to identify the location of various objects

• Compass points helps us identify:

• Identify the direction of each compass point: Compass Point Direction Blue Yellow Red Green

• Use the compass points to locate the following objects in relation to Pipehenge:

Pipehenge Lesson #3: Measuring Shadows


 * Learning Goals:
 * Understand that we see changes in our sky because of the earth’s rotation
 * Use pipehenge to monitor and measure shadows
 * Use measurements to make conclusions about changes in our sky

Background Information • What are shadows?

Questions • How will shadows change throughout the day?

Hypotheses • The direction of a shadow will change from _ __to__ _.

• The angle of the shadow will _ __as the day goes on.

• The length of a shadow will change from__ _ __to__ ___.

Collecting Data 8:00 10:00 12:00 2:00 Direction

Angle

Length

Results • As the day went on, the shadows moved from__

to __.

• As the day went on, the angle of the

shadow____.

• As the day went on, the length of the shadow__

_.

Conclusions • Direction and Angle- Since the shadows moved from

to ___, we can conclude that the

sun “moved” from__ __to__ __.

• Direction and Angle- Since the sun does not really move, we can

conclude that the earth is rotating from__ _

__to__ ___.

• Length- Since the length of the shadow__ ___,

then__ we can conclude that the sun

appeared__then__ ___in the sky.

• Since the sun does not really move, we can conclude that the

earth is__ __.
