SC.16.5 - Explain the basic processes of transcription and translation, and how they result in the expression of genes.


Subject
Integrated Science 2
Theme
RNA: Transcription & Translation (Lesson 4)
Grade
10th
Duration of lesson
90 min.
Materials
-Handout from last class
-Bingo cards (with amino acids)
- Codon sequences (to draw from bingo)
-Markers
-Candy
-Pencil
-Smart board
Common Core Standard(s)
SC.16.5 - Explain the basic processes of transcription and translation, and how they result in the expression of genes.
Lesson/Instructional Objective(s)
After the review and RNA presentation, students will complete the Day 2 portion of the worksheet with 70% accuracy (21/30), by transcribe the DNA into RNA and then translate it into the proper letter (amino acid).
Hook/Anticipatory Set

(How will you motivate the students?)

-Students will be able to practice base pairing RNA on the smart board (via this animation).
-This animation allows students to physically move the correct base pair in place, and also shows how the RNA translates into amino acids.
Procedures


1)      Class will begin with teacher explaining if as a class we maintain positive attitudes and good efforts in the lesson we will get through the lesson and be able to play Codon Bingo. (1 min)
2)      The lesson will begin with a brief explanation of RNA and its role *cookbook analogy (5- 8 min.)
3)      The instructor will then display the transcription virtual manipulative (http://www.classzone.com/cz/books/bio_12_fl/resources/htmls/animated_biology/unit3/bio_ch08_0257_ab_protein.html) explain it, demonstrate it, then allow students to come up and practice. The instructor will also briefly explain how to read the codon chart and locate the correct letter. (15 min)
4)      After a student or two goes the class will be instructed to begin their DNA scavenger hunt. Students who are having trouble are welcome to keep practicing on the board until they get a hang of it. (40 min.)
5)      The rest of class we will be playing codon bingo. Instructor will call out a certain nucleotide sequence and in order to mark the correct space, students must be able to properly read the codon chart. (40+ min.)

*Filler: Codon Bingo is good practice and also is never ending.
Assessment of learning Outcomes

(This should have been identified in the objective.)

Test and quizzes are only one type of assessment and are not the best way to check for understanding.

(Unit plans should have an informal assessment)



-After the review and RNA presentation, students will complete the Day 2 portion of the worksheet with 70% accuracy (21/40), by transcribe the DNA into RNA and then translate it into the proper letter (amino acid).

-Students participation will be observed and documented (on smart board with the RNA manipulative as well as during codon bingo)



Closure

(How will you summarize what you have discussed?)
-Before starting codon bingo we will review the role of RNA as a group (cookbook analogy)

-Instructor will also give students insight to next lesson discussing how the RNA knows where to transcribe the DNA (promoters) and what happens when the code is copied incorrectly (mutations).

Accommodations and Modifications for
ELLs



Level 1-3
Translated text (run by para for accuracy), frequent parent contact, hands on activities, graphs, drawing figures, samples of completed work, groups work, virtual manipulative practice

Level 4-5
Frequent parent contact, hands on activities, graphs, drawing figures, samples of completed work, groups work, virtual manipulative practice
Accommodations and Modifications for
ESE


Can record lectures (with awareness of instructor), extra time of test, hands on activities, group work, Use charts, tables, and graphic organizers, skeleton notes, translating key concepts, virtual manipulative practice

-Large laminated codon chart(s)
-Enlarger handouts (text)
Extensions for Gifted Students
-Gifted students will be required to make their own scavenger hunt word, translate it into RNA then transcribe it into DNA (working backward).
*This can also be offered to every other student as extra credit.
