Testing models with predictions
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will explore testing models with predictions through guided practice and application.
This lesson focuses on testing models with predictions. The scientific method provides a framework for systematic investigation and discovery.
Scientific models are representations of real phenomena that help us understand and make predictions. Models can be physical (3D molecules), mathematical (equations describing planetary motion), conceptual (diagrams of the water cycle), or computational (climate simulations). All models have limitations—they simplify reality, and features not represented accurately can lead to misinterpretations. The engineering design process applies scientific knowledge to create solutions to real problems: Define problem → Research → Brainstorm → Design → Build prototype → Test and evaluate → Redesign. Technology and science advance together—new tools (telescopes, microscopes, particle accelerators, satellites) enable new scientific discoveries, which in turn lead to new technologies. The iterative nature of both scientific inquiry and engineering design reflects how knowledge and capability grow through repeated cycles of testing and revision.
As you engage with this material, consider both the theoretical foundations and practical applications. Think critically about how this concept builds on prior knowledge and where you might apply it beyond the classroom.
Challenge yourself to go beyond memorization—seek to understand the "why" behind the processes and principles.
To examine systematically through observation and experiment
