This document outlines a 3-day 9th grade biology unit on Mendelian genetics. Each day focuses on a different genetics concept and mobile app. Day 1 covers Punnett squares and dominant/recessive traits using the Punnett Calc app. Day 2 addresses genetic disorders and gene screening using the Gene Screen app. Day 3 involves pedigrees, gene linkage, and practice questions using the Gene Tutor app. Across the 3 days, students work in pairs using mobile apps to reinforce concepts from direct instruction, then tweet summaries for assessment. A quiz will cover all unit topics.

1. Mendelian Genetics: 9th Grade High School Biology
Day 1
Headings Explanation
Georgia Standards SB2. Students will analyze how biological traits are passed on to successive generations.
Objective(s)
Learning Goal(s)
Understanding of the standards will be accomplished by each student that is able to:
a) explain the significance of Mendel’s experiments to the study of genetics
b) predict the possible offspring phenotypic and genotypic ratios from a cross using a Punnett square
Mobile App Used Punnett Calc ($0.99) https://itunes.apple.com/us/app/punnett-calc/id501273721?mt=8
Student Grouping Students will be grouped based upon the technology available. Students will be discretely placed with a
partner who has the required technology to use the Mobile Apps. (A survey from the beginning of the
semester asking about technology students have will be used to make groups). Students who have their own
devices will be paired up with students who do not have their own devices first, and then others will be placed
together accordingly and will be able to use the school provided technology.
Activities/Lesson  Direct instruction on heredity/inheritance, Mendel, dominant & recessive traits, genotypes &
phenotypes, and monohybrid punnett squares.
 The students will have their notes at hand while they access their Mobile App-Punnett Calc.
 Punnett Calc allows students to do many different types of calculations which we will use as a method
of double checking their answers. They will be doing the calculations with a partner on paper and use
the app in order to check their responses before moving on to the next set of punnett square crosses.
This not only saves me time by having to walk around and check all students answers, it will give them
a sense of independence and responsibility for learning how to cross them on their own.
 At the end of class, students will send in a tweet as the closure activity. (See below in assessment)
Instructional
Strategies
1. Students will have direct instruction for the notes at the beginning of class which will set up the
content for the app we will be using in this activity.
2. Students will send a Tweet to the group #Mrs_K_Bio_2222 at the end of class as a closure activity in
which students will summarize the key points they learned in this lesson. The next day we will open
with the responses from the tweets sent in.
Materials iPhones, iPads, or Laptops with iTunes installed

participation.

2. Mendelian Genetics: 9th Grade High School Biology
Day 2
Headings Explanation
Georgia Standards SB2. Students will analyze how biological traits are passed on to successive generations.
Objective(s)
Learning Goal(s)
Understanding of the standards will be accomplished by each student that is able to:
a) analyze genetic patterns to determine dominant or recessive inheritance patterns
b) summarize examples of dominant and recessive disorders
c) construct human pedigrees from genetic information
d) distinguish between various complex inheritance patterns
Mobile App Used 1. Gene Screen (Free) https://itunes.apple.com/au/app/gene-screen/id447754230?mt=8

together accordingly and will be able to use the school provided technology.
Activities/Lesson  At the beginning of class, students will be randomly placed into Buzz Groups and the tweets from the
day before will be projected on the screen. Students will have 2 minutes to review and discuss the
tweets from their peers as a review from the previous day’s lesson. Any questions or misunderstandings
can be cleared up during this time before moving on to the next lesson.
 Direct instruction on Genetic disorders will be given and students will read in the textbook about all of
the characteristics they need to know.
 The students will have their notes at hand while they access their Mobile App-Gene Screen.
 Using the Gene Screen App, students have the opportunity to how recessive genetic traits and diseases
are inherited and how certain diseases are more prevalent in different populations. Gene Screen also
provides information on some recessive genetic diseases and genetic screening programs.
 At the end of class, students will send in a tweet as the closure activity. (See below in assessment)
