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)
- Blue & Yellow only (BB, Bb = blue, bb = yellow)

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!

Love this activity. I have used it for years with my 7th graders. He really get into determining what the offspring will be.
