2/18 PTC Lab

Teacher: Gainous

Unit/Session: Genetics (PTC Lab)

Date of Instruction:  2/18/22

Standard/s: 

S7L3. Obtain, evaluate, and communicate information to explain how organisms reproduce

either sexually or asexually and transfer genetic information to determine the traits of their

offspring.

1. Construct an explanation supported with scientific evidence of the role of genes and chromosomes in the process of inheriting a specific trait.

2. Develop and use a model to describe how asexual reproduction can result in offspring with identical genetic information while sexual reproduction results in genetic variation.

Learning Target/ Teaching Point:

I can explain how organisms reproduce and transfer genetic information. 

Success Criteria:

• Explain how genes and chromosomes determine inherited traits

• Know the father of genetics and his experiments

• Use a model to predict genetic variation of offspring

Opening (I Do)

An engaging process for lesson introduction that is specifically planned to encourage equitable and purposeful student participation. Describe the instructional process that will be used to introduce the lesson.

INTRODUCTION/CONNECTION: 

Science Starter 

DIRECT INSTRUCTION:

Today’s lesson will determine if a student is a taster or non taster using ptc paper. The teacher will introduce phenylthiocarbamide and explain that it is a chemical used to test for genetic traits. 

Work Period  (We Do, You Do)

Students learning by doing/demonstrating learning expectations.  Describe the instructional process that will be used to engage the students in the work period.

TKES 1, 2, 3, 4, 5, 7. 8,10

GUIDED PRACTICE: 

The class will answer the hypothesis question. “Will you be a taster or non taster?” As a class, students will place the paper on their tongue and will describe what it tastes like. Next, the class will create a bar graph analyzing the results of the class. 

INDEPENDENT/COLLABORATIVE PRACTICE/DIFFERENTIATION:

Students will answer the conclusion questions individually as a review of today’s lesson. 

Closing  (We Check)

Describe the instructional process that will be used to close the lesson and check for student understanding .
