What students do
- Sort ten real consumer items into need, want, or marketing-created want, and defend the manufactured-demand category
- Analyze three historic ad campaigns (Listerine's 1920s bad-breath pitch, De Beers's 1947 diamond ring, the 2023 Stanley cup) for which tactic each uses
- Decode a real ad for scarcity, FOMO, social proof, emotional appeal, manufactured insecurity, or lifestyle marketing
- Audit a recent personal purchase and name its opportunity cost alongside the tactics that drove it
What it covers
- The difference between a need, a want, and a want manufactured by advertising
- Six marketing tactics, from scarcity and FOMO to lifestyle marketing, and how to spot each one
- How Listerine, De Beers, and Stanley all manufactured demand for a product people didn't know they needed
- How to audit personal spending against the tactics that shaped it
Learning targets
- Define the difference between a NEED (something required for survival or basic well-being) and a WANT (a preference that improves life but is not required), and use the difference to classify real consumer items
- Name and explain at least FIVE marketing manipulation tactics - SCARCITY-AS-TACTIC, FOMO, SOCIAL PROOF, EMOTIONAL APPEAL, MANUFACTURED INSECURITY, and LIFESTYLE MARKETING - and identify them in real ad campaigns
- Explain MANUFACTURED DEMAND - how advertising creates 'needs' that did not exist before (deodorant, Listerine bad breath, bottled water, diamond engagement rings) - using concrete case-study evidence
- Apply needs-vs-wants thinking to your own consumption (TikTok ads, Stanley cups, sneaker drops, energy drinks) and write a recommendation memo that protects your money from manipulation
Peek inside
A NEED is
Required for SURVIVAL or basic well-being
Food, water, shelter, clothing, basic healthcare
If you skip it long enough, your life falls apart
Roughly the same across people and cultures
The Core Distinction
A NEED is required for or basic well-being.
Examples of needs: food, water, shelter, , and basic healthcare.
A WANT is a that improves life but is not required.
You would fine without a want - maybe just less happy.
SECTION 2
1. When a company creates demand through advertising for a product that did not solve a real problem people already had, economists call it .
Why this matters
Nobody needed a diamond ring until De Beers convinced a country otherwise in 1947, and nobody needed one specific water bottle until the same playbook worked again in 2023. A hundred-year-old ad campaign and a viral one from last year use identical tactics.
Advertising feels like something that only works on other people. Naming the exact tactic, scarcity, FOMO, social proof, that shaped something they bought closes that gap fast, and the audit ends on their own last purchase instead of Listerine or De Beers.
From one teacher to another
Kids get uncomfortable at the right moment in this one, since by the end of the Listerine and De Beers case studies, they start noticing manufactured insecurity in their own For You page. The Stanley cup case study lands hardest because it happened to them last year, not to a previous generation. I built the closing audit so the lesson doesn't end on a vague takeaway; it ends with them naming the opportunity cost of something they actually bought.

Activity (Student)
Maya Reyes has students annotate three real campaigns, the 1920s Listerine halitosis ads, the 1947 De Beers diamond slogan, and the 2023 Stanley Quencher TikTok drops, tagging the specific marketing tactic each one leans on.
-
Activity (Answer Key)
Answers trace Listerine's jump from $115,000 to $8 million a year, the diamond tradition De Beers built starting in 1947, and the Stanley Quencher's climb from $74 million to $750 million, naming manufactured demand as the thread.
-
Exit Ticket (Student)
Three questions identify which item is a genuine need instead of a marketing-created want, name the tactic behind inventing a dull-skin problem before selling the cure, and define what manufactured demand actually is. Two tactics behind a real purchase and its opportunity cost finish the response.
-
Exit Ticket (Answer Key)
Clean drinking water is the genuine need, manufactured insecurity names the dull-skin tactic, and company-created advertising is the source behind manufactured demand. Credit depends on two named tactics and a stated opportunity cost.

Guided Notes (Student)
Maslow's five levels separate what's required from what's just preferred, then three ad campaigns get retraced, an invented halitosis scare in the 1920s, a 1947 diamond slogan, and a water bottle's jump from $74 million in 2019 to $750 million in 2023.
-
Guided Notes (Teacher Key)
Six tactics get named and grounded in a real case apiece, a 1947 diamond slogan, a 1976 lifestyle campaign for bottled water, and a $40 bottle holding about $1 of tap water, then total U.S. ad spending at $390 billion a year.
-
Quiz (Student)
A countdown timer, a TikTok energy-drink post, and a beach road trip commercial each get matched to the tactic behind them, from scarcity and social proof to a plain emotional appeal.
-
Quiz (Answer Key)
The countdown timer gets marked as scarcity, the TikTok post as social proof, and the Listerine ad as manufactured insecurity and demand. Opportunity cost then gets defined as the term for a dollar spent one way instead of another.
-
Slides
Listerine's sales jump from $115,000 to $8 million a year after popularizing the obscure term halitosis is paired with the 2023 Stanley cup boom that turned $74 million into $750 million, the same manufactured demand playbook decades apart.
-
Teacher Guide
One scavenger hunt sends students logging every ad they see for 24 hours, tagging each with a tactic and tallying whether most hit 50 or 100 by the next class. The extension work traces Hallmark's 1910s greeting cards back to the campaign that invented the demand.

Teacher Presentation Notes
Perrier's 1976 campaign sold plain water as a lifestyle choice, right before the script tracks Stanley Quenchers from about $74 million in sales in 2019 to $750 million after a 2023 relaunch. A discussion prompt runs the math too: $2,000 a year over 50 years tops $100,000.
