BHS Biology 5 E Lesson Design: DNA

ENGAGE    

Misconception Probe: "DNA, Genes, and Chromosomes"    -Four Corners    -Group Response

"What is a Chromosome" (video tour)    -Respond in science notebooks about changes between initial response and learning from web-tour 

EXPLORE    

DNA Extraction:     -Cheek cells    -Strawberries

Formative Assessment: Explain what they learned about DNA from extraction. Explain what was lacking in their knowledge from the extraction.

EXPLAIN    Students will manipulate DNA nucleotides to build

a DNA strand.

They will then compare their DNA strand with others in the classroom.

They will develop an explanation about the structure of DNA, as well as how differences in DNA may or may not lead to differences at the tissue, organismal level.

ELABORATE- Students will post by group what they think stem cells are and why they are important on wallwisher.com   

- Students will conduct very basic background research using google scholar to discover information about stem cells

- Students will be given 2 articles that are contradictory regarding usage/ethics of stem cells. They will individually reflect on the information that they have gathered and related that to the provided articles.  (This section is still *under construction*) 

EVALUATE    Students were given a pre-test at the beginning of the

unit. They will be given this same assessment.

The claim made in the explain portion will be evaluated using the claim, evidence, reasoning rubric.
