Life applicability
- Understanding radiation (medical X-rays, smoke detectors, radon in homes)
- why some materials are magnetic
- how screens (phones/TVs) work
Safety knowledge
- What radioactive symbols mean
- why you shouldn't open old electronics (CRT TVs, some clocks) that may contain radioactive materials
- safe distance from sources
Foundation for further study
How electrons behave; why atoms bond; basis for all other chemistry topics
Hands-on demo
Build a model atom using household objects (marbles, beans, or paper circles)
