Pipehenge: Poor Man’s Stonehenge

Description:  Pipehenge is a daytime astronomy device that can be used to determine patterns in the movement of our Sun and moon.  Pipehenge can be built using plastic pipes so that it is moveable or a permanent "climbable" structure.  According to the makers of this device, students can study astronomy during the day and internalize a model that they can use while observing the night sky.  Secondary students could build a device that could be used with elementary students in the same school district.
