HS-LS1-1

SCUSD NGSS Curriculum Guide ==== **HS-LS1-1: Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.** [//Assessment Boundary: Assessment does not include identification of specific cell or tissue types, whole body systems, specific protein structures and functions, or the biochemistry of protein synthesis//.] ====

Science Background for the Teacher:
Central Dogma/ DNA codons translate to amino acids, then the amino acids make proteins

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] ||
 * amino acids || proteins || bases: guanine cytosine, adenine, thymine, uracil || nucleus ||
 * DNA || codon || RNA ( messenger, transport, ribosomal) ||  ||

Possible Assessments (formative and/or summative):
[Description of assessment task]

Key Student Activity:
Pattern or sequences of the bases will determine the amino acid sequence of a protein cut and paste activities online internet activities

Key Teacher Demo/Activity:
how to use the codon coding sheet

Common Student Misconceptions:
role of proteins in life: all structure is protein DNA codes for proteins

Things to Avoid/Correct:
[Descriptions of imprecise language or other mistakes related to this topic that might have to be corrected at a higher grade band.]
