II. SUMMATIVE ASSESSMENT - PERFORMANCE TASK (1 PRODUCT)
PERFORMANCE STANDARD:
The learners should be able to design using multimedia, demonstrations, or models, a
representation or simulation of the atomic structure of common radioactive isotopes.
SITUATION: The Philippine Nuclear Research Institute is holding a multimedia arts contest with
the theme “A Beaming Future with Radioactive Isotopes”. Your teacher asks you to present a
multimedia arts presentation featuring 5 radioactive isotopes, their uses, basic information such
as atomic number, number of protons, electrons, neutrons, and mass number.
GOAL: Create a multimedia arts presentation featuring 5 radioactive isotopes, their uses, basic
information such as atomic number, number of protons, electrons, neutrons, and mass number.
ROLE: You are one of the contestants.
AUDIENCE: Judges in the contest
STANDARDS: You are going to be assessed using the following criteria: content, focus,
organization, graphics/visual impact, uniqueness/creativity and timeliness.
