MIA Maritime Infusion Biology Lesson Plan # COURSE / Unit: 7 Nucleic Acids-Relatedness and Crime Solving in Maritime Industry BIOLOGY/Biochemistry TRAINING AREA (Title): Lesson Lesson Number: # Macromolecules-Nucleic Acids Rev. Date: By 8 Aug 2012 Gina Doney _______ 7 2 Classes Duration: Biology One at Maritime Industries Academy Author: Gina Doney Date: XX October XXXX LEARNING OBJECTIVES: CLG The student will be able to: Students will use the building blocks of nucleic acids in order to demonstrate the structure of a DNA molecule. (nucleotides are building blocks of nucleic acids - sugar, phosphate, & nitrogen bases; DNA is a double helix) **Assessment: Students answer questions about the structure of DNA at the end of class (from PRI) Students will use the structure and function of DNA molecules in order to solve a maritime industry crime. 3.1.1 The student will be able to describe the unique characteristics of chemical substances and macromolecules utilized by living systems CCSS WHST.11.1.a,e RST.11.2,11.7, 11.8 CFR / STCW (nucleic acids; nucleotides are building blocks - sugar, phosphate, & nitrogen bases; DNA is a double helix) TEACHING AIDS REQUIRED: A1. Projector A2. Large Presentation Screen A3. Videos / Multi Media – water videos A4. Presentation(s) / Power points A5. White or Blackboard or Flip Paper and Easel Add any other Aids required Here: Nucleic Acids STUDENT ASSIGNMENTS: 1. Students will take notes on nucleic acids 2. Students will practice drawing/modeling a nucleotide 3. Student will respond to an article on copper theft STUDENT ASSESSMENTS: 1. Students will be able to label a DNA molecule (nucleotide) retrieved from the biology HSA * STUDENT ACCOMMODATIONS MADE Notes Pages Extended time Reduced distractions from others Reduced distractions to others Checks for understanding BIBLIOGRAPHY / REFERENCES / WEB RESOURCES USED: 1. Copper thieves article from WJZ 13 1.0 Begin the Lesson Teacher Actions: Students Actions/Accommodations MIA Maritime Infusion Biology Lesson Plan # 7 Nucleic Acids-Relatedness and Crime Solving in Maritime Industry Rev. Date: By WARM UP PRETEST! Both DNA and RNA A. contain phosphate B. contain amino acids C. are a double helix D. are inorganic Pretest! Provide notes that DNA and RNA are both nucleic acids. They both carry genetic information and have a phosphate. ENGAGE: ENGAGE: Ask students about the pattern that has been made and ask students to “crack the code” something like the following: Ship- Apple Apple-ship School bus-teacher Teacher-school bus Etc… Students should identify that everywhere there is a ship there is an anchor and visa versa and everywhere there is a shell there is a fish and visa versa. This is the introduction into DNA. Ask students to make their own “code.” Ask students to make sure they have their books or a piece of paper for notes. Show movie at about 1:18-2:05 Ask the questions: What did the “code” look like in the video? Students should describe that it was a whole bunch of letters… Why is the DNA code called “universal?” Students should recall that DNA is the same “code” in all organisms. EXPLORE: EXPLORE: Students read Copper Thieves Targeting Unoccupied Homes… Begin discussion on using DNA in order to solve tough crimes. Discuss copper and other metals that are received and transported by the Port of Baltimore. What actions do they take to keep these items safe? DAY 2 EXPLAIN: Notes (powerpoint) DNA= DeoxyriboNucleic Acid. Nucleotides are the building blocks for DNA. Each nucleotide consists of a phosphate, a sugar and a base. [Draw a simple model on the board/PowerPoint for students to include in their notes using a circle, hexagon, and a rectangle to represent the three parts.] 4 bases, A= adenine, T= thymine, G= guanine, and C= cytosine [A, T, C, G] Complementary bases pair A T, C G (held together by hydrogen bonds) There are two strands for DNA and it is called a double helix. EXPLAIN: 8 Aug 2012 Gina Doney MIA Maritime Infusion Biology Lesson Plan # 7 Nucleic Acids-Relatedness and Crime Solving in Maritime Industry Rev. Date: By 8 Aug 2012 Gina Doney DRAW a picture of several nitrogen bases and have students make the pairs and label them Because of chemical charges, DNA looks like a twisted ladder with each base pair as one of the rungs. This shape is called a helix. [Draw a quick sketch]. Provide picture (from HSA) for students to put in their books/notes. EXTEND: Students practice using DNA to show both crime scene relations and relationships among species (marine species example involved.) Students will solve a mystery. EXTEND: EVALUATE: EVALUATE: HSA question with DNA picture (From PowerPoint) Students will label 1-4 WITHOUT using their notes. Extension:
