Epidemics and pandemics are the focus of this Grade 8 science worksheet, using the 1918 influenza pandemic to explore how infectious disease outbreaks affect communities differently. Students distinguish an epidemic from a pandemic, examine evidence of disease spread, and consider how living conditions, access to health care and public decisions can shape the consequences of an outbreak.

The reading passage connects scientific ideas with a historical account of community experience. It introduces the difference between an outbreak affecting a community or region and one spreading across countries or continents. Students encounter evidence such as case reports, dates and maps, then consider disruptions to work, school, travel and family care during the 1918 influenza pandemic.

Science meets historical evidence and community perspectives

A distinctive feature of this resource is its attention to how historical sources should be interpreted. The passage discusses Lheidli T’enneh woman Margaret Gagnon’s recollection, described by Mary-Ellen Kelm in “First Peoples Struggling to Survive,” published by Shared Histories Canada. It also notes that the Lheidli T’enneh were forcibly relocated to Shelley in 1911. Students are encouraged to recognize that one person’s account represents a particular perspective, rather than assuming that every community member experienced events in the same way.

This approach builds source-evaluation skills alongside science learning. Students consider who created a historical record, why it was created, whose experiences it represents and whether a conclusion is supported by the available evidence. They also examine why respectful study of disease outbreaks should consider social conditions and avoid blaming groups.

What students practise

• Multiple-choice questions address epidemic and pandemic definitions, evidence of disease spread, the 1918 influenza outbreak, community impacts and responsible interpretation of historical accounts.
• True-or-false questions reinforce geographic scale, social conditions, the limits of individual memories and historical source evaluation.
• Short-answer questions ask students to explain the difference between epidemics and pandemics, describe disruptions to community life and justify comparing historical records with community perspectives.
• A labelled diagram, categorizing activity and short note offer further opportunities to organize and communicate ideas about the topic.

Included with the worksheet

• The student worksheet with a topic-based reading passage and activities.
• A separate PDF answer key for checking student responses.
• Student Notes lines at the bottom of the worksheet.
• A Teacher Guide inside the answer key PDF, including Learning Objectives, Teaching Tips, Discussion Questions and Common Mistakes.

Classroom use

Use this Grade 8 infectious disease resource when teaching micro-organisms and their effects on human communities, introducing epidemic and pandemic vocabulary, or practising evidence-based explanations. It can support a reading-and-response lesson, guided discussion about historical sources, or review of how scientific evidence and social context contribute to an explanation of an outbreak.

By connecting disease terminology with documented community experiences, the worksheet gives students a concrete way to examine both the spread of infection and the wider consequences for people’s lives. The separate answer key and embedded teacher guidance support review and follow-up discussion without requiring a separate teacher guide file.
