Notes for Teachers

  • This lesson will take place over several classes following instructions of the standards and will serve as a summative assessment.
  • Students will work individually to collect data and create their monster.
  • Creativity and originality will be encouraged, while following the guidelines and specific genetic traits. There is not one correct look to the monster!

List of Materials

This list is not all inclusive, but rather suggested items that can be used- feel free to add/edit and create your own list of items.

  • Pape tubes (from toilet paper rolls or paper towel rolls)
  • Styrofoam or plastic cups- various sizes
  • Cardboard boxes- various sizes
  • Pipe cleaners
  • Craft sticks
  • Toothpicks
  • Rubber bands
  • Pom poms
  • Scissors
  • Paint
  • Straws
  • Googly eyes
  • Tape
  • Glue (various types of glue would work)
  • Other craft/building materials as needed

  • Student packets
  • 1 coin for each student
  • Writing utensils
  • Colors (markers, crayons, etc.)

Standards

Life Science:

8.L3U1.9 Construct an explanation of how genetic variations occur in offspring through the inheritance of traits or through mutations.

  • In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.

8.L4U1.11 Develop and use a model to explain how natural selection may lead to increases and decreases of specific traits in populations over time.

Core Idea:

L3: Genetic information is passed down from one generation of organisms to another.

Science and Engineering Practices:

● ask questions and define problems,

● develop and use models

● plan and carry out investigations

● analyze and interpret data

● use mathematics and computational thinking

● construct explanations and design solutions

● engage in argument from evidence

● obtain, evaluate, and communicate information

Crosscutting Concepts:

cause and effect

● structure and function

● systems and system models

● stability and change

● scale, proportion, and quantity

Objective(s):

Today the student will collect, analyze and interpret data.

Today the student will provide evidence of inherited traits from parents in offspring.

Today the student will construct a model to describe the outcome of sexual reproduction where two sets of parent traits will be used to determine the offspring’s phenotypes and display genetic variations.

Today the student will use and define vocabulary that include: genotype, phenotype, traits, offspring, dominant trait, and recessive trait.

Agenda

You will need approximately 90 minutes- this can be broken into two 45 minutes sections/classes if needed.

-Engage students with video- ask driving question/s and make connection to activity.

-Model the activity and collection of data. (demo the coin toss and recording of data)

-Discuss questions that students may have.

-Provide guidance on steps and make sure to address the “why”….”Why would you flip the coin two times?” the data represents the genetic material provided by each parent in sexual reproduction.

Intro/Driving Question/Opening

-What physical characteristics do you have that makes you different from your classmates? What about your siblings or family members?

-Think about your phenotypes (the traits we can see)…..

Watch the following video and think about how the monsters are different from one another….

Monsters Inc. ad clip: We scare because we care

Today you will go through 4 phases:

Engage: Watch the video

Collect Data: Coin toss/ record monster characteristic information.

Engineer: Start to create your monster based on the characteristics on your data sheet.

Reflect: Students will reflect on their monster’s inherited traits. They will create a diagram and label each phenotype and genotype. Students will also make a connection to inherited traits.

Hands-on Activity Instructions

  • Make a connection- Ask Students what they noticed about the video/monsters.
  • Students will work individually to gather their data by flipping a coin. Students will flip the coin twice to represent each parents' trait/genetic contribution that is passed to the offspring.
    • Make sure to have enough coins to give one to each student.

  • Monster Sketch
    • Students will use the handout to sketch their monster based on the data/traits that were recorded during the coin flips.
    • This is a good time to brainstorm what types of materials will be needed for the construction of the monster.

THIS A GOOD STOPPING POINT IF YOU ARE WORKING ON 45 MINUTE CLASSES.

  • Monster Construction:
    • Students can gather materials that you have supplied (or ones that you allowed them to bring from home)
    • Students should work on the construction of their monster at their own desk
    • You can walk through the class at this time to help students who are struggling and provide support if needed.
  • After students have finished the construction of their monster, they will draw another diagram that identifies the following:
    • Genotypes- write out each one/label
    • Phenotypes-Label all the traits
    • Label dominant and recessive traits
    • Answer critical thinking/reflection questions at the end of the sketch.

Assessment

  • Assessment: When evaluating or assessing engineering projects we should be looking at the process and the product. 
  • Process
    • Did the student follow the engineering design process by basing the design off the genetic data, developing prototypes/rough draft sketch, and reflection?
  • Product
    • Does the final product meet the requirements (can the correct phenotype bee seen, were genotypes listed in the reflection that match up with the design and data? while staying within constraints (time and materials provided)?
  • �This could be done with a rubric, a performance (students orally present the data and how it is displayed in the monster’s phenotype), an oral presentation or digital presentation (explaining their process and product), a visual product (a poster, video clip, etc).
  • Many of these ideas are outside the timeframe of a single day lesson so this is a good fit for a longer unit of study- you could even add time to the back end for the presentations and delivery.

Assessments:

  • Science and Engineering Practices
    • Double check the data collection- you could implement a peer check
    • Ensure correct data is displayed in the monster’s physical characteristics.
    • Engineer the final product based on your data collection.
    • Reflect on the practice and how your design applied to genetics and inherited traits through sexual reproduction.

  • Math and ELA
    • The students can do a wide variety of activities to make this interdisciplinary.
    • ELA inclusion is seen in the reflection write up at the end of the lessons.
    • Students can graph the data based on the whole group dominant and recessive traits, probability of the coin toss and what traits might be displayed and estimations.

Differentiation

Students who struggle with the data collection could be grouped together.

  • For my group of IEP students, I allowed for them to work as a groups for data collection, but then they each had the option to make their own monster.
  • My ARISE students were not able to do the data collection piece without the help of an aid- they had assistance with the data collection and then all helped to build one collective model for the group.

Remediation

Extension/Enrichment

An extension for this activity could be the oral presentation or the creation of digital presentations.

Utilization of technology in the form of PowerPoints, Google Slides, Stop Motion, and so many other formats for the students to showcase their design and their knowledge of the content.
