Mississippi Science L.6.1

L.6.1 is a cluster heading. These are the individual standards under it.

• L.6.1.1

  Use argument supported by evidence in order to distinguish between living and non-living things, including viruses and bacteria.

• L.6.1.2

  Obtain and communicate evidence to support the cell theory.

• L.6.1.3

  Develop and use models to explain how specific cellular components (cell wall, cell membrane, nucleus, chloroplast, vacuole, and mitochondria) function together...

• L.6.1.4

  Compare and contrast different cells in order to classify them as a protist, fungus, plant, or animal.

• L.6.1.5

  Provide evidence that organisms are unicellular or multicellular.

• L.6.1.6

  Develop and use models to show relationships among the increasing complexity of multicellular organisms (cells, tissues, organs, organ systems, organisms) and h...

What Students Need to Do

Students use evidence to argue whether bacteria and viruses are living. They compare cells by their parts and show how those parts help organisms survive. They model how cells form tissues, organs, organ systems, and whole organisms.

02

What Mastery Looks Like

A student uses cell images to explain that living things are made of cells and can be single-celled or multicellular. They identify a bacterium by its lack of a nucleus and use cell parts to sort plant, animal, fungal, and protist cells. They can trace a skin cell through tissue, organ, and organ system.

03

Common Misconceptions

Students may call a virus a cell or think bacteria have nuclei. They may think every cell has chloroplasts, or that a tissue is one large cell.

04

How to Assess It

Show pictures of a bacterium, a virus, and a plant cell. Ask students which are cells, which are living, and what evidence supports each answer.

1. 01

   Have pairs build plant and bacterial cells from clay, labeling membranes, walls, and the plant cell's nucleus, chloroplasts, vacuole, and mitochondria.

2. 02

   Ask: Is a virus alive if it reproduces only inside a cell? Write a claim with two pieces of evidence.

3. 03

   Play a card match: pair membrane, wall, nucleus, chloroplast, vacuole, and mitochondrion cards with cards describing their jobs.

4. 04

   Draw a scraped knee and label skin cells, epithelial tissue, skin, the integumentary system, and the whole person.

• FB.3

  Students will demonstrate an understanding of how the structure of living organisms supports the essential functions of life.

• BIO.1A

  Students will demonstrate an understanding of the characteristics of life and biological organization.

• L.K.1A

  Students will demonstrate an understanding of living and non-living things.

• L.2.3B

  Students will demonstrate an understanding of the interdependence of living things.
