Question

match the tool to its primary purpose
armillary sphere
telescope
paper instruments
sextant
astrolabe
gnomon/sundial
manipulative paper models to visualize astronomy concepts
track distances between planets and stars along the ecliptic
to view objects in space
casts a shadow to calculate time
new - age - determines the angle between horizon and a celestial body
old - age - calculate altitude and navigating latitude

Explanation:

An armillary sphere is a model used to visualize astronomy concepts. A telescope is used to view objects in space. Paper instruments can be used as manipulative paper - models for visualization. A sextant determines the angle between horizon and a celestial body. An astrolabe was an old - age tool to calculate altitude and navigate latitude. A gnomon/sundial casts a shadow to calculate time.

Answer:

Armillary Sphere - manipulative paper models to visualize astronomy concepts
Telescope - to view objects in space
Paper Instruments - manipulative paper models to visualize astronomy concepts
Sextant - newer - age - determines the angle between horizon and a celestial body
Astrolabe - old - age - calculate altitude and navigating latitude
Gnomon/Sundial - casts a shadow to calculate time
