This was the fifth annual Science Day at the University of Maine at Presque Isle.
Activities are open to the public.
A model of the solar system that will extend from Presque Isle to Houlton, a distance of about 40 miles, is being built. The Earth has been placed at Percy's Auto Sales, about 2 miles south of Presque Isle on the Houlton road. The model of Pluto will be at the Visitor's Center in Houlton. See The Northern Maine Solar System Model web site to check on the progress of the model.
