Plastic Egg Genetics

Easter-Eggs

It is that time of year again: time to ask everyone you know to save their plastic Easter eggs and that you will be more than happy to take them off their hands – once the kids have emptied out the goodies, of course! 

Below are some links to teachers who have used this lesson in the past:

  • University of Southern California (link)
  • Western Kentucky University (link)
  • Science Matters (link)
  • Homeschool Life Journal (link)
  • And a big thank you to Brent from Georgia who did a great job explaining how to set up and use this activity with your students, see his detailed video below.

Resources:

  • Original Lesson Plan (link)
  • Student Worksheet I created for the lesson plan (pdf)
    • NOTE: the colors in this activity represent Incomplete Dominance and their outcomes
    • Here is a nice review of the three different types of dominance from Khan Academy (video link)
    • For Dominant and Recessive Traits only, this lesson would have to be modified and use 1 whole egg for each parent, and the answers would NOT be inside the eggs:
      • Blue & Yellow only (BB, Bb = blue, bb = yellow)
        • Blue egg – 2 blue pieces
        • Blue egg – 1 blue piece, 1 yellow piece
        • Yellow egg – 2 yellow pieces
          • Open eggs for genotypes, then make punnett squares
      • Purple & Pink only  (PP, Pp = Purple, pp = pink)
  • BrainPOP Video: Heredity (free link)
  • BrainPOP Video: DNA (free link)

If you have used this lesson in the past, would love to hear how it went! If you wrote about it on your blog, I would love to add your link to the site as well!
