7.3: Structures & Function of Life 3 Dimensions & Progressions

Unit 4

STANDARD ●​ 7.3.1 Plan and carry out an investigation that provides evidence that the basic structures of living things are cells . Emphasize that cells can form single-celled or multicellular organisms, and that multicellular organisms are made of different types of cells. (MS-LS1-1)

CONCEPTS

SKILLS

●​ Structure of living things ●​ Cells ●​ Single-celled or multicellular organisms

●​ Plan investigation ●​ Investigate ●​ Provide Evidence

LEARNING PROGRESSIONS

●​ All living things are made of cells ●​ Cells are the smallest unit that can be said to be alive ●​ Cells are too small to be seen by the eye ●​ Microscopes help us to see cells ●​ There are single-celled organisms, or organisms made up of many cells ●​ There are different types of cells

VOCABULARY ●​ Cell

●​ Protist ●​ Algae ●​ Magnify ●​ Microscope

●​ Nucleus ●​ Cell wall ●​ Cell membrane ●​ chloroplast

●​ Structure ●​ Multicellular ●​ Unicellular ●​ Organisms ●​ Bacteria

POSSIBLE PHENOMENA ●​ When viewed under a microscope a pinecone and a penny have very different microscopic structures. ●​ A sample of pond water has individual, moving organisms when viewed under a microscope. ●​ White blood cells can chase and consume/kill bacteria. END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS ●​ I can do an investigation to provide evidence that all living things are made of cells. ○​ Language Supports: ■​ Nouns to support skills (i.e. document, draw, details, sketch)

■​ Word to describe observations (rough, smooth, compared to, smaller than, larger than, etc.) ■​ Labeling and graphics (lines, arrows, labels, etc.)
