The Learning Center

Material a teacher can use on Monday.

The teaching goal is not memorising names. It is learning to ask what the evidence is — a skill that transfers to every subject.

By level

K–5

One inventor, one problem, one object. Ask: what was hard before this existed?

6–8

Read a patent abstract together. Separate what it claims from what people say it claims.

9–12

Compare two sources that disagree. Assign an evidence level and defend it.

College

Trace an innovation lineage across a century and evaluate attribution.

Adult learners

Follow one everyday object back to its documentation.

Homeschool

Build a timeline from primary-source dates rather than summaries.

Primary-source exercise

  1. 1. Choose any record in the Patent Archive and note its number.
  2. 2. Look the number up in the patent office's public full-text database.
  3. 3. Read the claims. Write in one sentence what was actually claimed.
  4. 4. Compare that sentence with how the invention is described online.
  5. 5. Assign an evidence level and justify it in three sentences.
