• Title: Is Radioactivity always harmful for humans?
• Description: This Inquiry Learning Space aims at understanding the different types of radioactivity particles and the basics about radioactivity decay. Factors that influence the radioactivity intensity (distance from radioactivity source, exposure time and presence of absorbers) will also be discussed. The Radioactivity Lab examines the intensity of radiation over distance, demonstrating the effects of the inverse square law. Students investigate the intensity of radiation being emitted from a radioactive Strontium-90 source, by setting distances at which a Geiger counter measures radiation, and collecting radioactive particle counts at each of these distances. A table holding the radioactive source is rotated until the source is aligned with a hole in a thick lead plate. The head holding the Geiger-Muller tube is moved to these distances from the radioactive source.

SCORM 1.2 SCORM 2004

A SCORM package is a collection of files which are packaged according to an agreed standard for learning objects. SCORM packages are zip files that can be integrated in any LMS (Learning Management System) that supports the standard (Moodle, Blackboard, …) and that can be used for presenting multimedia content and as assessment tools. Thus, you can integrate your Virtual Excursion in Moodle and other LMSs by downloading it as SCORM.
