Parts of the building looked like a science laboratory while another looked more like a distant planet.
At Discovery School in Lancaster last week, more than 100 students tried their hand at various stations that made up Camp Invention.
The program, which fostered creative thinking through hands-on activities, was geared to rising first- through sixth-graders.
It started Monday and ran through Friday.
One room in the building was turned into "Planet Zak," where students had crash landed and had five days to get off.
