Teaching collection
Classroom activities
Turn science questions into guided discussion, research and investigation with topic-based activities for middle and secondary classrooms.
A flexible starting point
Use an explainer to open an inquiry
These archived learning pages connect accessible science background with prompts that encourage students to ask questions, examine evidence and explain what they find.
What’s included
- Discussion questions
- Guided activities
- Knowledge checks
- Source-story context
Browse activities by subject
Some activities cross subject boundaries and therefore appear in more than one field. Review each archived page before assigning it and adapt the material to your learners.

How to use the archive
Plan a thoughtful lesson
The collection provides historical science context rather than a fixed curriculum. Educators should check current specialist sources where knowledge, policy or guidance August have changed.
Choose the core question
Select an activity that fits the scientific idea, student readiness and time available.
Review the archive page
Check vocabulary, references and conclusions before sharing the material with learners.
Add current evidence
Pair older background with recent, authoritative sources when the field has advanced.
Discuss uncertainty
Ask students what the evidence supports, what remains unclear and what could be tested next.
Curriculum connections
Explore broader collections organized for middle-grade and secondary science learning.
Science standards: Grades 5–8
Find archive topics connected with middle-grade science concepts and inquiry.
Science standards: Grades 9–12
Explore secondary-level connections across life, Earth and physical sciences.
Frequently asked questions
Are these complete lesson plans?
No. They are flexible archive resources with questions, activities and checks for understanding. Educators should supply lesson timing, assessment criteria and any required materials.
Which learners are these activities for?
The collection is most readily adapted for middle and secondary classrooms, but suitability depends on the topic, reading level and instructional goals.
Why do some activities appear under multiple subjects?
Many scientific questions are interdisciplinary. Tsunamis, for example, involve Earth processes as well as the physical behavior of waves.
Should archive material be checked against current research?
Yes. Use the pages for foundational concepts and historical context, then verify time-sensitive claims with recent authoritative sources.
Do the activities require laboratory equipment?
Requirements vary. Review the selected page in advance and substitute safe, accessible materials where appropriate.
Does Whyfiles provide individual teaching advice?
No. Educators remain responsible for age appropriateness, accessibility, supervision and compliance with their institution’s requirements.
