Guided Reading Short Sheet: pg. 320 – 321

Objective:1)TSW memorize the hierarchy of genetic material (nitrogen base pairs, DNA, genes, and chromosomes) through building a diagramming of the nucleus and its inner parts. (DOK 8-3d)

Materials: tape (5 pieces per student), scissors, cell/nucleus/chromosome/DNA strand/base pair cut outs, construction paper, overhead projector, transparency of DNA Hierarchy Diagram

Do Now: (5 min)

1. Which statement explains why the nucleus can be referred to as the brain of plant and animal cells?

  1. It releases energy to the cell.
  2. It controls the activities of the cell.
  3. It stores food, water, and wastes of the cell.
  4. It controls the materials that go into and out of the cell.

2. Why do children look like their parents? Answer in complete sentences.

Set: (5 min)

TTW tell the class that she is handing out the next set of directions for class on a half sheet, but, unfortunately, they are in the form of a code. Figure out the code, and follow the instructions. TTW watch as students figure out the code and hand out tickets for students who correctly decode it. TTW explain that this code acts just like your DNA. Your DNA is a code in your body that tells your body what to do, how to grow and how to look. Today, we are going to begin to learn about DNA and hereditary (the passing of genetic traits from parents to children). TTW state objectives.

Procedures:

  1. TTW remind students of Mr. Bolland’s lesson by saying “In Mr. Bolland’s lesson on ecosystems, you talked about hierarchies, what is a hierarchy?” (A: ordering system from smallest part to largest part). Hereditary material works the same way, it is ordered as big parts that are broken down into smaller parts. (1 min)
  2. TTW guide students through filling in the flow chart on the using the overhead. (5 min)
  3. TTW display model of the next activity: genetic materials hierarchy cut out. TTW instruct students that they will be cutting out a nucleus, chromosome, DNA strand, gene and a set of nitrogen base pairs. TSW then tape each part as flap on a “cell” in order from smallest to biggest so that when you lift the “nucleus” you see the “chromosome” inside. Then, when you lift the “chromosome” you see the DNA strand it is made out of and so on and so forth until you get to base pairs. (1 min)
  4. TTW distribute materials and go over sharing rules (2 min). **If there are not enough scissors for the entire, start half of the class on the reading questions, then trade.
  5. TSW complete cutout activity. TSW may color and decorate their genetic materials cut out when finished, so that it can be hung in the classroom. (15 min)

If students finish early:

  1. TTW pass out “Guided Reading Short Sheet” while instructing students to open their books to page 320. TTW give instructions for the sheets fill in answers as we read the text aloud. (1 min)
  2. TCW read pages 320 -321 aloud, stopping as needed for students to fill in answers to the short sheet. TTW not indicate where answers are, but will pause when more than half of the class is writing an answer. (6 min)
  3. TSW go back through the reading to answer questions on the “Guided Reading Short Sheet” that he/she missed and then go through answers as a class with a ticketmaster (3 min)

Closure: (6 min)

  1. TTW state the hierarchy of genetic material within the cell. TTW select students to fill in the blanks in the order of the DNA hierarchy as she says “The nucleus of a cell contains ______(chromosomes), the chromosomes contain ______(DNA strands), the DNA strands contain ______(genes), the genes are made of sequences of ______(nitrogen base pairs).
  2. TTW collect cut-outs materials and assignments.
  3. TTW preview next lesson.

Assessments:

Informal: TTW monitor (m) as students complete DNA hierarchy (c) diagram.

Formal: TTW collect and grade (m) the completed DNA hierarchy (c) cut-out activity and enter it as a daily grade in the gradebook (d).

Directions: Answer the following questions using complete sentences.

  1. What is hereditary material?
  1. What controls how offspring (children) will look?
  1. True or False. DNA is hereditary material.
  1. All of the information that is in your DNA is called ______.
  1. The order, or sequence, of DNA bases forms a ______. From this DNA ______,

the cells get ______.
