Spangler Phenomenon - Black Light Secret Message Investigation

This Spangler Phenomenon lesson about analog and digital signals is crafted to include a video created by Steve Spangler exclusively for Kesler Science. The interactive investigation will keep your students on the edge of their seats and engage their analytical skills with this Really Big Question: How does the design of modern technology help it operate more reliably than older pieces of technology?

Science education gets an upgrade as Steve Spangler and Chris Kesler become a force of nature in this collaborative series. Created in the 5E framework, each lesson aligns to middle school NGSS physical science.

Spangler Phenomenon: Brain-bending Lessons to Engage Student Curiosity

Lesson: Black Light Secret Message

Standard: MSPS4-3: Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.

Learning Objective: How does the design of modern technology help it operate more reliably than older pieces of technology?

CCC/SEP: Structure and function; Obtaining, evaluating, communicating information

Lesson Contents:

In Part 1: Think Like a Scientist, students think and behave like real scientists and engineers as they analyze inspiring phenomenon related to analog and digital signals. They get inspired by a Steve Spangler video, Black Light Secret Message, and then students will create secret messages of their own.

In Part 2:  Study Like a Scientist, students gather facts from an engaging article that relates to analog and digital signals. You can also pause here to add other activities and experiments like Station Labs and Inquiry Labs to expand their experiences.

In Part 3: Work Like a Scientist, students reevaluate their conclusions after watching the exclusive Steve Spangler explanation video. They then engage in a writing, drawing, or building activity – or all three! – to demonstrate what they have learned about the essential question: How does the design of modern technology help it operate more reliably than older pieces of technology?

Each topic includes:

• Complete teacher directions with materials list, usage tips, learning objectives, and answer key
• Hand-outs for classroom use
• Two Steve Spangler videos to introduce and conclude the investigation
• Crisp, clear presentation slides in standard and digital interactive formats
• PowerPoints that can be uploaded cleanly to Google Slides
• Vimeo links to the videos to remove the concern over inappropriate ads and comments

Be on the lookout for more products in the future from this fantastic partnership between Kesler Science and Steve Spangler!
