MS-LS1-1 — Cells as the Basic Unit of Life
Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.
What students need to learn
Plan and conduct an investigation
CoreStudents must engage in a scientific investigation rather than only reading about cells. They gather observations or data that help answer the question of whether living things are made of cells.
Use evidence to support the claim
CoreThe standard emphasizes evidence-based reasoning. Students should use what they observe in specimens, images, or models to justify the conclusion that living things are composed of cells.
Understand that all living things are made of cells
FoundationalStudents learn the core idea of cell theory that cells are the basic unit of life. This includes recognizing that both simple and complex organisms are made of one or more cells.
Distinguish unicellular and multicellular organisms
CoreStudents should recognize that some organisms consist of a single cell, while others are made of many cells. This helps them understand biological diversity and different levels of organization in living things.
Recognize different numbers and types of cells
ExtensionMulticellular organisms contain many cells that can differ in structure and function. Students begin to see that specialized cell types contribute to how organisms survive and function.
I can investigate and use evidence to show that all living things are made of cells, either one cell or many different kinds of cells.
