MS-LS1-1

SCUSD NGSS Curriculum Guide ==== **MS-LS1-1: Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.** [Clarification Statement: Emphasis is on developing evidence that living things are made of cells, distinguishing between living and non-living things, and understanding that living things may be made of one cell or many and varied cells.] ====

Science Background for the Teacher:
Microbiology, cell structure and function, subcellular organelles living vs. non-living

Key Vocabulary:

 * [key vocab term for this performance expectation] || [key vocab term for this performance expectation] || [key vocab term for this performance expectation] || [key vocab term for this performance expectation] ||
 * cells, cell wall, cell membrane || living vs. non living ||  ||   ||
 * abiotic vs biotic ||  ||   ||   ||

Possible Assessments (formative and/or summative):
Summative: microscope to determine single cell vs multi celled organism

Key Student Activity:
venn diagram: living vs. non living, superglue in a Petri dish needs of living things characteristics of living things (MERRR movement excretion growth and develop, response, reproduce microscopy: onion skin, cheek cells, prepared slides, Elodea, yeast, celery, pond water, rain water yeast experiments--CO2 production

Key Teacher Demo/Activity:
sand vs. sand plus yeast vs. sand plus baking soda

Common Student Misconceptions:
once living vs. living, seeds (dormant), egg, cut flowers materials that came from living things cell membrane vs. cell wall all living things are made of cells

Things to Avoid/Correct:
osmosis and diffusion
