Investigate the evidence.
Understand the choices.

Five ways to investigate history. Follow evidence, explore choices under pressure, decode stories and places, and practise checking what appears in your feed.

YOUR LEARNING LAB · 5 WAYS IN

History is not a feed. Learn to read what is behind it.

Open a case, follow a clue, compare records and build your own evidence-based explanation. You do not need to know everything before you start — curiosity is the first tool.

For teachers and learners. These activities use short, clearly labelled adaptations of information from historical sources and museum research. Adaptations are not presented as original quotations. The Holocaust was the systematic, state-sponsored persecution and murder of six million European Jews by Nazi Germany and its collaborators. Other groups were also persecuted and murdered. Treat testimony and historical records with care; do not rank suffering or judge people under coercion as if they had free choices.

The Evidence Desk

Historians do not ask only whether a source is “true” or “false”. They ask who made it, why it exists, what it can establish, what it leaves out, and how it fits with other evidence.

Your task: examine three historical source files. For each one, choose the strongest interpretation supported by the evidence.

5 investigations · approx. 15 minutes
Source file A · LawGermany · 15 September 1935

The Nuremberg Laws

Carefully adapted source summary — not a quotation

Two laws passed by Nazi Germany stripped Jews of full Reich citizenship and prohibited marriages between Jews and people classified as being of “German or related blood”. The laws made antisemitic racial ideology part of state law. The law text describes what the regime authorised and prohibited; by itself, it does not document every local act of enforcement or every person’s experience.

Source file B · DiaryŁódź ghetto · March 1942

A young diarist writes about hunger

Carefully adapted source summary — not a quotation

An anonymous girl diarist in the Łódź ghetto recorded severe shortages of food and the daily struggle to find something to eat. In a separate entry the next day, she described how a sunny day briefly lifted her mood, even while the ghetto fence made her feel trapped. These entries give evidence of one young person’s experience and of the coexistence of hardship, feeling, and ordinary daily observation.

“When it’s so cold, even my heart is heavy. There is nothing to cook today; …”

A photograph of deportation

Carefully adapted source summary — not a quotation

A USHMM collection entry identifies a photograph showing Jewish children being deported from the Łódź ghetto during the German authorities’ September 1942 roundup. Its caption supplies a place, date, historical event, and collection credit. The image is evidence, but the caption and related records are essential to identify the event responsibly; a photograph alone cannot tell us every person’s name, thoughts, or later fate.

Look closer: what does this photograph prove?

Start with what is visible. Then use the archive caption to separate observation from documented context and from claims the evidence cannot establish. The image is a historical document, not an invitation to guess what the people pictured were thinking or feeling.

Choices Under Pressure

This case study asks how we analyse decisions when power is radically unequal. The purpose is not to decide whether people in the ghetto made “good” or “bad” choices from a safe distance. It is to identify who held power, what options were constrained or removed, and whose perspectives are needed to understand an event.

5 case questions · approx. 15 minutes
Historical case fileŁódź ghetto · September 1942

German authorities demand deportations

Historical summary based on USHMM research

In early September 1942, German authorities ordered that 20,000 people be deported from the Łódź ghetto, including children, older people, and the sick. The German authorities held the decisive coercive power. Chaim Rumkowski, head of the Jewish Council, announced the demand to the ghetto population on 4 September. During the roundup, German SS and police forces carried out deportations; people who tried to hide or flee faced extreme danger, and more than 500 Jews were murdered during the operation.

The situation was shaped by German occupation, imprisonment, starvation, threats, and the removal of meaningful freedom. The role of the Jewish Council and Rumkowski has been debated, but analysis must begin with the coercive system imposed by the Nazi authorities and the fact that the people targeted were victims of persecution.

Source: USHMM, “‘Give Me Your Children’: Voices from the Lodz Ghetto”. Read the full account and further questions ↗

Before you begin: distinguish three things

  • Power: who created and enforced the threat?
  • Constraint: which options were blocked by violence, imprisonment, or the threat of collective punishment?
  • Perspective: whose testimony or records do we need before drawing a conclusion?
CASE QUESTION 1 OF 5Score: 0

Case study complete

Remember: analysing constrained decisions is not the same as blaming people who were persecuted. Historical responsibility depends on power, actions, intent, and context.

Discussion: how should historians write about constrained choices?

In pairs, discuss two questions. Try to support each point with a detail from the case file.

  1. Why is it misleading to describe the September 1942 roundup as a free choice made by the ghetto population?
  2. What additional sources would help us understand the event from the perspectives of parents, children, German officials, Jewish Council members, and people who tried to hide?
  3. How can a historian examine Rumkowski’s actions without ignoring the power of the German authorities or treating the Jewish population as a single voice?
A strong discussion answer:
  • names the German authorities’ power and coercion;
  • recognises that people in the ghetto did not have equal power or safe options;
  • does not treat the Jewish population as one uniform group;
  • distinguishes documented facts from interpretation and identifies evidence still needed.
Choices · The Bystander's Dilemma

When people witness injustice

The handbook asks learners to distinguish perpetrators, collaborators, bystanders and rescuers, and to examine the conditions that shaped people's responses. Fear, conformity, prejudice, self-interest, access to information and perceived risk may influence behaviour. Understanding these circumstances is not the same as excusing the consequences.

Which conclusion is most responsible?

You are studying a documented case in which a neighbour witnessed persecution but did not intervene. What should you investigate before reaching a conclusion?

Key concepts: bystander behaviour, diffusion of responsibility, conformity and moral responsibility. The historical case must be selected and documented by the teacher; do not invent a named example.

When prejudice becomes state policy

Historical summary — not a quotation from a propaganda poster

Nazi antisemitism did not consist only of insulting messages or individual prejudice. The regime used propaganda and racial stereotypes while also changing laws, excluding Jews from citizenship and public life, encouraging social exclusion, and using state institutions to enforce persecution. The 1935 Nuremberg Laws are one example of antisemitic ideology being turned into law.

Verification routine: pause → identify the original source → check date and context → compare independent reliable sources → decide whether sharing is useful and safe.

Apply the verification routine

Imagine a post claims that a historical photograph proves a dramatic event, but gives no date, location, photographer, or archive reference. Write down the first three checks you would make before sharing it.

Look for these steps:
  • find the original image or document and the holding institution;
  • check the caption, date, location, creator, and any later edits or reposts;
  • compare the claim with reliable, independent sources;
  • avoid reposting harmful or misleading material while checking.
The Power of Words · Standing Up Against Hate

Language analysis studio

The handbook examines how language can label, stereotype, exclude, persuade, dehumanise or protect. Sort the fictional examples below. They are deliberately neutral training examples and do not reproduce historical slurs.

“A few people missed the deadline because the instructions were unclear.” What kind of statement is this?

Now analyse a verified historical source selected by your teacher: Who created the message? Who was its audience? What emotions might it seek to evoke? Who is presented as “us” and who as “them”? What facts are omitted or distorted? Record the source's title, date, creator and institution before discussing it.

Letters Across Time · From Memory to Action

Write across time — with historical care

Use a documented testimony, diary or biography as the starting point for a reflective letter. Do not write in the voice of a real victim unless the task is explicitly a clearly labelled creative response, and never invent quotations or claim to know what a person would have wanted.

Choose one prompt:

  • Write a letter to a future student explaining why one particular source should be preserved and read carefully.
  • Write a letter to a museum or archive asking how it verifies, describes and preserves a testimony or object.
  • Write a letter to your local community proposing one practical way to preserve knowledge of Jewish life and the Holocaust.

From memory to action: make your proposal specific, realistic and connected to what you have learned. It might involve researching a local trace, improving the description of a memorial, sharing a verified archive resource, or challenging an unsupported claim responsibly.

Discussion: historical propaganda and today's information environment

  • What is the difference between a stereotype and a specific, verifiable claim?
  • Why is “everyone is sharing it” not evidence that a claim is true?
  • How can we compare propaganda techniques across time without claiming that every modern dispute is equivalent to the Holocaust?
Pathway · Stories

A Suitcase, a Photograph, a Name

Objects and photographs can open a route into an individual story, but they do not explain themselves. Work from observation to questions, then to facts confirmed by a reliable record. This follows the handbook's object-based inquiry lesson.

Object inquiry · 15–20 minutes
Investigation method

Look before you know

Choose a documented object or photograph from a museum or archive. Its record should identify provenance and connect it to a named person or clearly described historical context. Do not assume that an unprovenanced suitcase belonged to a particular victim.

  • Observe: material, condition, marks, visible names or dates, setting.
  • Ask / infer: who might have used it, how it travelled, what questions it raises. Label every inference as a hypothesis.
  • Confirm: details stated by the archive or biography. Mark unknown details as unknown.

Which statement is strongest?

You see a worn suitcase in a museum. Its record says it belonged to a named person who was deported in 1944. Which interpretation is best supported?

Behind Every Number Is a Story

The handbook asks students to read statistics alongside individual biographies or testimony. The figure of six million Jewish victims describes the scale of the Holocaust; an individual account helps investigate a particular life and experience. Neither type of evidence replaces the other.

  1. What question can a well-documented statistic answer?
  2. What can an individual biography or testimony help us understand that a total cannot?
  3. Why must one person's story not be presented as representative of every victim?

For classroom use, the teacher should select a verified statistic and a documented biography/testimony, cite both sources, and explain whether the number is an estimate or an exact count.

Make a museum label

Write a 100–150-word label connecting one documented object to its owner or historical context. Include at least two details supported by the source, one limitation, and the exact archive or museum reference. Never invent a quotation or present imaginative writing as testimony.

Listen · Oral history

One voice. One minute. Three questions.

Survivor testimony is a historical source: personal, situated and shaped by memory. Listen to a short excerpt in the archive, then return to the questions below. You do not need to listen to graphic or distressing material to complete this activity.

Stories · Children's Voices

“The Butterfly” — poetry, memory and Terezín

The handbook proposes an interdisciplinary study of Pavel Friedmann’s poem “The Butterfly” (1942), written in the context of the Terezín ghetto. Explore how literary images and contrasts can preserve a particular voice, while keeping the historical context and the limits of one poem in view.

Read and investigate: use a teacher-verified edition of the poem and a reliable historical source about Pavel Friedmann and Terezín. Do not reproduce an unverified text or treat a creative interpretation as a historical quotation.

  • What contrasts does the poem create between the world inside the ghetto and the world beyond it?
  • How does the butterfly function as an image or symbol? Which words support your interpretation?
  • What can a poem reveal about a writer’s expression and perspective, and what historical questions require other sources?
  • How does the historical context change the way you read the poem?

Which statement best describes the source?

A poem written by a prisoner in a ghetto is used in a lesson about the Holocaust. What is the most careful approach?

Creative response — clearly your own

Create a visual, sound-based or written response inspired by the poem’s themes. Label it as a contemporary response; do not imitate Friedmann’s voice or present new lines as his words.

Pathway · Memory

Memory Detectives

Investigate traces of Jewish life in a local community: street names, buildings, cemeteries, maps, photographs, museum collections and oral-history records. A trace raises questions; it does not automatically prove a conclusion.

Local-history inquiry · 15–20 minutes
Detective rules

Four questions for every trace

  1. What can I see or read directly?
  2. Who created this source, when, and for what purpose?
  3. What can I state with confidence, and what is only a hypothesis?
  4. What other source could confirm, complicate or challenge this finding?

Use three or four teacher-selected local sources. Record the title, creator or holding institution, date if known, and where it was found. If a date or creator is unknown, write “unknown” rather than guessing.

Detective challenge

A historical map shows a building on a street where Jewish residents once lived. What can you responsibly conclude from the map alone?

Monuments Speak · Why Do We Remember?

Memorials communicate through location, names, images, materials, inscriptions and the decisions of those who created them. They also leave things out. Examine a local or museum memorial using these prompts:

  • Who is commemorated, and who created the memorial?
  • When and where was it made? What historical context shaped it?
  • What does its design communicate? What is not represented?
  • How might different visitors interpret it?

Designing a Memorial

Create a proposal for a memorial that is historically grounded and respectful. Identify whom or what it commemorates; the evidence used; the location and reason for choosing it; the words or symbols included; accessibility for different visitors; and one limitation or difficult decision. Do not use suffering as decoration or invent names and personal histories.

Sources for further learning

Start with collections that provide context

Use these resources to explore original records, photographs, diaries, and testimony. Always read the archive caption and historical explanation alongside an item.

Evidence · If These Walls Could Speak

Read a building as a historical source

Architecture, photographs, objects and places can preserve traces of community life. They are “silent witnesses”: they prompt questions, but need to be read alongside documents, memoirs, laws, photographs and verified local history. The handbook’s worked example focuses on the Sofia Synagogue and the history of Bulgarian Jews during the Second World War; adapt the method to a documented local site.

  • Describe visible architectural or material details before interpreting them.
  • Check the building’s date, architect, purpose and changes over time using reliable records.
  • Compare the physical site with at least one contemporary photograph or written source.
  • Ask which histories are visible at the site and which require other records.

What can a photograph of a historic building establish?

You have one exterior photograph of a synagogue. Which statement is best supported?
