What educators are saying

We don't cover this topic but I thought it would be a fun activity to use at the end of the year to introduce my students to the topic of DNA. They liked it.
I LOVE this resource! I use it each year without fail. The biggest thing I am thankful for is the ability to use it easily in the classroom as a normal task card activity. If we need to transfer to distance learning, I love that I am able to still use this resource very easily.

Description

So much fun! DNA fingerprinting & forensics simplified specifically for middle school!

Get this activity at a big discount in our DNA & Chromosomes BUNDLE!

In this activity, students will:

  1. Read a silly (not scary) murder mystery. The scene is set for students to figure out who killed Mr. Henry Lord Whippleton. There are two suspects... and one of their DNA fingerprints will match the DNA found at the crime scene!
  2. Get an introduction to DNA fingerprinting with a 1-page introduction and a tiny bit of practice.
  3. "Process" the two suspects' DNA (involving cutting and pasting paper DNA strips) to make a DNA fingerprint for each suspect.
  4. Compare the DNA fingerprints they have generated to the one found at the crime scene. Mystery solved!

Teacher Notes:

  • Generally, with time for introduction and discussion, this activity takes 2 class periods.
  • NGSS Science & Engineering Practice: Developing and using models
  • Please note: This resource is NOT editable.

Standards

NGSSMS-LS3-1
Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism. Emphasis is on conceptual understanding that changes in genetic material may result in making different proteins. Assessment does not include specific changes at the molecular level, mechanisms for protein synthesis, or specific types of mutations.
NGSSMS-LS3-2
Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation. Emphasis is on using models such as Punnett squares, diagrams, and simulations to describe the cause and effect relationship of gene transmission from parent(s) to offspring and resulting genetic variation.
