Support your IB Environmental Systems & Societies students in building strong, scientifically rigorous Internal Assessments with this fully developed lesson focused on designing valid investigations.

This engaging and highly practical lesson helps students move beyond simply choosing a topic and teaches them how to design a reliable, valid, and well-controlled ESS investigation.

Perfect for:

IB DP ESS teachers
IA support workshops
Year 12 ESS students beginning fieldwork planning
Revision of scientific methodology skills

What’s Included?
Full Lesson PowerPoint and worksheet actvity on recognising poor examples in methodology

A complete, ready-to-teach lesson covering:

  • Valid methodologies
  • Controls and controlled variables
  • Replication and repeated measurements
  • Reliability vs validity
  • Scientific rigor
  • Uncertainty in investigations
  • Refining methods

Interactive Student Activities
