By the end of this lesson, students will demonstrate how DNA is condensed (supercoiled) into structures called chromosomes by building a quick and simple chromosome model. This activity is great for teaching students about the levels of organization w/in genetic material. Using the model they built, students will differentiate between DNA, chromatin (upper grade levels), chromosomes, and genes. Students will use their model to identify a gene as a section of DNA that codes for a protein (trait).
This activity is...
- great for English Language Learners (ELL)
- quick and easy to make.
- hands-on and engaging
- easily modified up or down for middle or high school
- easy to follow with the step-by-step instructions/pictures provided
