The assessment measures what is intended to
be measured in the content standard. Students could pass this task by truly
knowing and being able to do what is asked for in the content standard.
(The
rubric clearly relates to the specific content standard being covered and
includes all of the skills needed to complete a quality product) TEKS/Student
Expectations: Insert the TEKS the lesson is covering
TEKS Bio/IPC 2A:
Plan and implement investigative procedures including
asking questions, formulating testable hypotheses, and selecting equipment
and
technology.
TEKS Bio/IPC 2C: Organize, analyze, evaluate, make inferences, and predict
trends from data.
TEKS Bio/IPC 2D: Communicate valid conclusions.
TEKS Bio/IPC 3A: Analyze, review, and critique scientific explanations,
including hypotheses and theories, as to their strengths and weaknesses
using
scientific evidence and information.
The task asks
students to show their “know how” on something important and challenging,
not just their knowledge. (Students develop the focus of the task by
building on their own experiences to determine the problem and to look for
possible solutions.)
Essential Question/s or Engaging Questions As students
study about genetics, seen how genes determine traits, and how traits are
seen in our physical appearance they will begin formulating questions such
as: What are the chances of my future children having the familial trait?
How can I determine the probability that the next generation will have this
trait? What trends does my family history show? How can I track the
inheritance of a trait in my family? What are the moral and ethical
considerations of genetic planning?
Student
generated questions:
Use an on-line cat genetic
lab to gain familiarity of the reaction of gene traits.
Then construct their own
family pedigree based on one desired trait. Create a visual to be presented
to the class.
The
task is worthy of the time and effort required to complete it. (The
amount of time devoted to completing the task is very consistent with the
complexity of the task or the embedded content standards)
Time Frame: Ongoing
High Level Processes
The task requires complex thinking skills
(critical/ creative thinking, decision- making, problem solving).
(Students are operating at the synthesis/
evaluation levels involving one or more complex thinking strategies (e.g.,
problem-solving, decision-making, scientific inquiry) involving integrated
concepts and big ideas.)

List or describe activities that support the selected Bloom's
Level(s): 1. Knowledge and
comprehension - Introduction presentations and lectures on genetics.
2. Knowledge, comprehension, application, and analysis - Practice with
punnett square
3. Knowledge, comprehension, application, and analysis - Dominant Fly Lab.
Analyzed the genetic makeup of the chromosomes to construct a fly exhibiting
multiple traits.
4. Knowledge, comprehension, application, - Identify Dominant and Recessive
traits Quick Lab. Applying what they know about dominant and recessive
traits to determine their own genetic makeup.
5. Knowledge, comprehension, application, analysis, synthesis and evaluation
- Based upon learning over the course of this unit, students will be able to
construct their Familial History of a particular familial trait over 3
generations and hypothesize the probability that the 4th generations the
family trait. The students will justify their hypothesis with scientific
data.
6. Evaluation - Students will assess their peers presentations/pedigree
accuracy.

7. Evaluate the ethics of gene planning in humans.
Ethics and
Reproductive Issues: The Dilemma of Choice
The assessment is likely
to elicit consistent scores over time. The scores on the task will reflect
true achievement of the content standard not variance in testing conditions.
(The criteria are explained clearly with measurable
expectations. Criteria are consistent across all dimensions, and lend
themselves to self-monitoring)

Important Content
The
task incorporates the content standard and the big ideas and essential
concepts of the discipline. (The culminating task
is directly related to a well- defined and articulated set of content
standards and essential concepts.)
Concepts/Topics: The Students will
learn about Mendel and genetics. They will gain a knowledge of the
historical impact of his work, Study of dominance and recessive traits, how
to use and construct Punnett squares, monohybrid and dihybrid genetic
crosses.
Concepts: Dominant and Recessive traits, Pedigrees. Predictions of future
trends in familial traits.
Students
Evaluate the possibility of planning their future children's
characteristics.
Authenticity
The task reflects
what people might actually do in the real world- real life issues, themes,
problems. (The culminating task is relevant to students and
involves creating a product that has a purpose beyond the classroom that
directly impacts the students.)
Individuals are always curious about their traits and how they are
inherited, and what their future offspring will look like or what they will
inherit from them. In the culminating task they will be able to make these
determinations for themselves and prove to the class by constructing a
family pedigree.
The students will participate in the following activities prior to the
culminating task.
1. Two days of interactive PowerPoint lectures and video clips about
Mendel’s Genetics; Punnett Squares, pedigrees, monohybrid and Dihybrid
crosses.
2. Dominant Fly lab with interactive Smart board technology and handheld
activities that students will use to illustrate and demonstrate monohybrid
crosses.
Transgenic Fly Lab
3. Students will distinguish their own traits and compare and contrast with
lab partners.
4.
Students will perform an on line cat lab and evaluate the outcome of their
crosses.
5.
Students will evaluate the value of genetic counseling for humans.
Culminating Task.
Student will ultimately categorize their own traits and produce a visual aid
to exhibit their potential offspring’s physical characteristics. Student
will choose which trait to represent in family history. Trace its occurrence
and make a hypothesis about its inheritance to a future generation while
supporting their conclusion with scientific evidence. Student will also
choose format to design visual aide.
Clarity of Task and
Assessment Criteria
It
is clear from reading the task that the student will know exactly what they
are to do to complete it, including required products and scoring criteria.
(The
culminating task is clearly defined; the assessment criteria are given so
that students understand the expectation of excellence throughout the
process.)
Culminating
Performance Task: The students
will hypothesize the probability of their offspring receiving a chosen
family trait, based upon analysis or a student constructed familial
pedigree. They will design a visual representation that justifies their
conclusion as to the chances of four offspring receiving the specific trait.
Students will also evaluate the validity of their peers created visual
representations showing familial inheritance.
Technology Use
Technology (computers, handhelds, software applications, peripherals,
Internet) is used in a seamless fashion to promote student learning. (Technology
use is directly connected and needed for task completion involving a broad
variety of applications.)
Technology Applications /How is technology integrated into your lesson? Will use a
variety of applications such as but not limited to inspiration, PowerPoint,
word, excel, internet, to complete the activities and ultimately the
culminating task.
Instruction is tailored to the learning readiness, cultural background,
interests, talents, and learning profile of the students
(Differentiation is clearly
articulated and involves significant adjustments or alterations to the
culminating task and surrounding
activities based on the interests, readiness, and learner profiles of the
students.) Differentiation:
