Vector Projections and Components
Understanding how to project one vector onto another and decompose vectors into orthogonal components, with applications in physics.
Key Questions
- Explain the geometric interpretation of a vector projection.
- Analyze how vector projection can be used to find the component of a force in a specific direction.
- Construct the projection of one vector onto another and interpret its meaning.

About This Topic
This topic examines the role of money in American elections, focusing on the landmark Citizens United v. FEC decision. Students analyze the rise of PACs and Super PACs, the concept of 'corporate personhood,' and the debate over whether campaign contributions constitute protected free speech. They also explore the impact of the 'permanent campaign' on a legislator's ability to govern.
For seniors, this is a lesson in the intersection of economics and politics. It connects to the First Amendment and the 14th Amendment's Equal Protection Clause. This topic comes alive when students can physically model the patterns of campaign spending by 'buying' ads and influence in a simulated election cycle.
Active Learning Ideas
Simulation Game: The Campaign Budget
Students are given a fixed budget and must decide how to allocate funds: TV ads, social media, 'dark money' groups, or grassroots organizing. They must explain the 'ROI' (return on investment) for each choice in terms of votes.
Formal Debate: Is Money Speech?
Students debate the central question of Citizens United. One side argues that spending money to spread a message is a form of expression; the other argues that unlimited spending drowns out the voices of ordinary citizens.
Gallery Walk: The Ad Wars
Display various campaign ads (positive, negative, and 'issue' ads from Super PACs). Students rotate and identify who paid for the ad and what 'loophole' or rule allowed that specific type of spending.
Watch Out for These Misconceptions
Common MisconceptionSuper PACs can give money directly to candidates.
What to Teach Instead
Super PACs are 'independent expenditure' committees; they can spend unlimited money but cannot coordinate with the candidate's campaign. Peer-led 'Coordination Audits' help students see the (often blurry) line between independent and direct support.
Common MisconceptionThe Citizens United ruling was about individuals giving more money.
What to Teach Instead
It was primarily about *corporations* and *unions* being allowed to spend money from their general treasuries on political ads. Peer discussion about 'Corporate Personhood' helps clarify the legal logic used by the Court.
