MS-LS4-4 Variation and Genetic Diversity Lab

Description

MS-LS4-4 Variation and Diversity Lab Preview

SNAPs Lab Stations Activities require students to use science, math, literacy, problem-solving and engineering skills. They are designed to enhance students’ understanding of scientific concepts and help students apply scientific ideas to the real world. Each station activity promotes skills so to develop students into proficient and competent scientific thinkers.

SNAPs lab activities have five components:
• Science Skills Station to develop science skill proficiency
• Narrative Station to build science literacy
• Assessment Station to evaluate learning and understanding
• Problem-Solving Station to foster engineering design
• Synthesis Station and Project to inspire higher-order learning

DIGITAL LABORATORY – DISTANCE LEARNING & DIGITAL CLASSROOMS
• This lab is offered in a digital format to support digital classrooms & distance learning.
• The digital lab activity is designed to work with Google Slides and Microsoft PowerPoint
• The digital lab activity CANNOT be edited. However:
– Students can manipulate text boxes
– Students can create tables, graphs and diagrams
– Students can insert images and drawings

GOOGLE FORM ASSESSMENT STATION
• The assessment station is offered as a self-grading Google Form.
• Questions are all short answer and are 100% editable.
• Suggestions for use are included in the download.

DISTANCE LEARNING COMPATIBILITY
SNAPs lab activities are rated for their ease with distance – independent learning. Refer to the preview for more information about how well this laboratory works in a fully digital classroom and with distance learning.

EDITABLE DOCUMENTS
This download includes an editable word document (docx file) of all lab components:
• Pre-Lab and Post-Lab Activities
• The Lab Overview
• Lab Station Activities and Questions
• Directed Synthesis Project (when applicable)

Important Notes:
• Diagrams, illustrations, tables and graphs essential to lab activities are included
• Illustrative clipart is NOT included
• Editable documents and rubrics are included with the FREE SNAPs Setup Guide

Editable files allow you to:
• Edit the scope of the activities so to suit your students’ needs
• Edit the materials required based on resource availability
• Create single-period “mini-labs” using activities at the individual skills stations

The activities at each station in this lab are detailed below.

Variation and Genetic Diversity Stations Lab Activity Learning Objectives
1. Identify sources of genetic variation.
2. Discuss the importance of genetic diversity in a species.
3. Conduct an investigation to study how genetic variation of traits in a population increases some individuals’ probability of surviving and reproducing in a specific environment.
4. Predict how changes in an environment can alter the probability that individuals of a population will survive and reproduce.
5. Use a computer model to explain the peppered moth phenomenon during the Industrial Revolution.

Science Skills Station
Students will conduct an investigation to study how genetic variation of traits (specifically, color) increases some individuals’ probability of surviving and reproducing while suppressing others’ probability of surviving and reproducing. Students will consider how environmental changes can alter the probability of surviving and reproducing. Students will tabulate and graph data to summarize the findings of the investigation.

Narrative Station
Students will read a passage about genetic variation and diversity. Students will also watch a video about processes and events that change the genetic variation and diversity of a population.

Assessment Station
At this station, students will answer questions about key terms and ideas relating to variation and genetic diversity. Students must employ lower, mid and higher order thinking skills to answer these questions.

Problem-Solving Station
Students will use a computer model to study thenatural selection of the peppered moths of the Industrial Revolution. Students will use the model to study how changes in the environment altered the probability of survival for two variations of moths (dark and light colored).

Synthesis Station
Students will compose a CER (claim-evidence-reasoning) report to summarize the lab. Students are provided the claim statement and must support the claim with observations, data and other information gathered in the lab. Students will explain how the evidence supports the claim using scientific reasoning.

Synthesis Project
Students will have a choice of 11 projects. Refer to the SNAPs Lab Stations Best Practices and Setup Guide for directions and suggestions on how to conduct the project.

This download includes:
• A pre-lab assignment and post-lab reflection
• Directions and questions for each lab station
• Student recording sheets
• Teacher Key

Additional Materials Required:
2 Computers or tablets
1 Set of colored pencils
Large red piece of paper or cardstock
Red, blue, green, white and yellow paper (2-3 pieces each)
5 Ziploc bags

LINKS TO VIDEOS
This laboratory requires internet to access videos. Videos are hosted on SafeShare.TV so to safely watch and share educational YouTube videos without ads, comments and other distractions. Shortened and full link(s) to SafeShare.TV included. Full link to original YouTube video(s) included.

NEXT GENERATION SCIENCE STANDARDS
This laboratory satisfies NGSS MS-LS4-4. It combines the three dimensions of science learning – science and engineering practices, disciplinary core ideas and crosscutting concepts – to meet the standard. This lab also makes interdisciplinary connections to STEM, Math CCSS and ELA CCSS to build the appropriate skills.
