Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells. (MS-LS1-1)
Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function. (MS-LS1-2)
Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment. (MS-LS4-4)
Gather and synthesize information about technologies that have changed the way humans influence the inheritance of desired traits in organisms. (MS-LS4-5)
Concepts and Skills
* Power Standard Content
LS1.A: Structure and Function (Human Body Systems intro)
All living things are made up of cells, which is the smallest unit that can be said to be alive. An organism may consist of one single cell (unicellular) or many different numbers and types of cells (multicellular). (MS-LS1-1)
LS1.B: Growth and Development of Organisms
Plants reproduce in a variety of ways. Sometimes this reproduction depends on animal behavior and specialized plant and animal features. (Pollination) (MS-LS1-4)
LS1.C: Organization for Matter and Energy Flow in Organisms
Plants, algae (including photoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used immediately or stored for growth or later use. (Cellular Respiration & Photosynthesis) (MS-LS1-6)
LS1.B: Growth and Development of Organisms
Organisms reproduce, either sexually or asexually, and transfer their genetic information to their offspring. (secondary to MS-LS3-2)
LS3.A: Inheritance of Traits
Variations of inherited traits between parent and offspring arise from genetic differences that result from the subset of chromosomes (and therefore genes) inherited. (MS-LS3-2)
LS3.B: Variation of Traits
In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other. (MS-LS3-2)
LS4.B: Natural Selection
In artificial selection, humans have the capacity to influence certain characteristics of organisms by genetic engineering. One can choose desired parental traits determined by genes, which are then passed on to offspring. (MS-LS4-5)
Critical Language (Science & Engineering Practices)
A student in seventh grade can demonstrate the ability to apply and comprehend critical language by constructing a scientific explanation based on valid and reliable evidence obtained from sources (including students’ own experiments) about cell biology and genetics.

Structure and function
Living organisms are made out of cells and special structures are responsible for particular functions in organisms.
The body is a system of multiple interacting subsystems that form a hierarchy from cells to the body.
