Mutations and Genetic Changes - FREE Video Worksheet - Middle School Science

Why do some people have sickle cell disease while others have protection from malaria? How can the same type of genetic change be harmful, helpful, or have no effect at all? The answer lies in understanding mutations - changes to DNA that can alter proteins and affect how organisms function!

Standards:

NGSS: 

• MS-LS3-1

TEKS: 

• 8.13.B, BIO.7.B, BIO.7.C, BIO.10.D

⭐ What's Covered?:

✅ What mutations are and how they occur in DNA 
✅ How genes code for proteins and why proteins are essential 
✅ The connection between DNA changes, protein changes, and organism effects 
✅ Types of mutations: substitutions, insertions, and deletions 
✅ Why some mutations are harmful, some helpful, and many neutral 
✅ Real examples: sickle cell anemia, lactose tolerance, and beneficial mutations 
✅ How mutations drive evolution and create genetic diversity

What will the students be doing?

● Students will be given either a printed or digital handout to record answers on.

● Either individually or as a class watch the video

● Then, they will use the video and their own knowledge to answer the questions.

● Use questions to spark discussions and apply information beyond the page!
