# Timing Sheet (Ethereum Interactive Lecture, 90 minutes)

Owner: instructor
Format: lecture-first 60/30 with anchor demo and stragglers' protocol
Reference: ../../prd.json story D6, ../slides/ethereum_interactive_lecture.tex
Pre-class checklist: ../pre_class/checklist.md (encouraged, not required; lecture works without it)

| Minute | Block | Slide range | Activity | What slips first if late |
|--------|-------|-------------|----------|--------------------------|
| 00 to 02 | Room setup | n/a | Pre-load Remix in instructor browser, project on screen, confirm Etherscan opens | Skip room walk-around |
| 02 to 12 | Act 1: The shared doc | 1 to 5 | Title (1), not financial advice (2), Google Doc analogy (3 to 5) | Cut the second analogy example |
| 12 to 22 | Act 2: Identity to write | 6 to 9 | Accounts, public keys, signatures, TEST WALLET ONLY warning. Interactive: think-pair-share with written-card alternative on "what if anyone could pretend to be you?" | Cut think-pair-share, keep written card |
| 22 to 32 | Act 3: The cost of writing | 10 to 13 | Transactions, gas, real fee in dollars | Cut the dollar conversion exercise |
| 32 to 35 | Physical stretch break | 14 | 90-second stand-up-and-look-out-the-window slide | Skip if running early; never if running late |
| 35 to 38 | D11 Sepolia anchor demo | 15 to 16 | Instructor projects pre-recorded video of Sepolia HelloWorld deploy + Etherscan view. Live Sepolia view if available, otherwise screenshot. Source of truth is the recording in instructor_kit/sepolia_anchor_assets/. | Use screenshot only, skip live |
| 38 to 48 | Act 4: A doc cell that runs itself | 17 to 20 | Smart contracts, EVM, why deterministic. Where the Google-Doc analogy breaks (append-only, irreversibility). Interactive: on-chain treasure hunt of one historical mainnet tx (not the ENS first-reg, see slide 19 footnote for the chosen tx) | Cut treasure hunt, show screenshot only |
| 48 to 50 | Hard reset checkpoint | 21 | Instructor projects Remix on screen, announces "everyone follow along on screen now". Catches students who lost the thread. | This block is non-negotiable; protect it |
| 50 to 60 | Act 5 + 6 bridge: reading the doc, what we are about to build | 22 to 26 | Etherscan as a UI on the doc. Bridge: HelloWorld preview. | Compress into 5 minutes |
| 60 to 68 | Workshop step 1: open Remix, drop in HelloWorld.sol | n/a | Students open Remix in a fresh tab, paste the contract from the lab guide, read it line by line | TA walks the room |
| 68 to 76 | Workshop step 2: compile + deploy to Remix VM | n/a | In-browser chain. Read greeting via deployed-contract panel. | TA helps stragglers |
| 76 to 80 | Workshop step 3: optional Sepolia level-up | n/a | For students who arrived with funded MetaMask only. Everyone else moves to step 4. | Cut entirely if running late |
| 80 to 81 | Stragglers' protocol | n/a | TA pulls aside any student still without a deployed contract for a 5-min focused projector walkthrough. Rest of class proceeds. | Non-negotiable; protect it |
| 81 to 83 | Workshop step 4: instructor notebook demo | 27 | 2-minute "by the way you can also do this in Python" demo. Students do not execute. Notebook is take-home. | Cut to 30 seconds if late |
| 83 to 88 | Workshop step 5: 5-question post-quiz | 28 | Quiz on concepts (account, tx, contract, gas, EVM, Google-Doc analogy). Concept-based; non-deployers can score 100%. | Hand out as take-home if late |
| 88 to 90 | Close | 29 to 30 | Recap: what is shared, what is private, what to never do (test wallet warning, not financial advice). Pointer to take-home notebook. | Non-negotiable; protect it |

Total: 90 minutes exact.

## Hard reset at minute 50

If, at minute 50, more than 25% of students have not yet followed along (i.e. they are still on the slides without a Remix tab open), the instructor projects Remix on screen and announces verbatim: "Everyone follow along on screen now. We will rebuild together." The hard reset sacrifices Act 4 individual interaction but protects the workshop window.

## Stragglers' protocol at minute 80

At minute 80, the TA scans the room for any student still without a "Deployed Contract" panel visible in their Remix. Those students are pulled aside to a side projector for a 5-minute focused walkthrough. The remaining students proceed with steps 4 and 5. No student leaves without an artifact.

## Slip behavior summary

The schedule has 7 explicitly cuttable items totaling 11 minutes. The 90-minute budget can absorb up to 11 minutes of slippage before the close (minutes 88 to 90) is at risk. Beyond that, the post-quiz becomes take-home.
