Hi everyone,
I was at the super market today and saw the Easter displays, and it
reminded me of this lesson plan. The lesson is offically called "Plastic
Egg Genetics" and it is a great hands-on way to practice punnett squares
and to have student self check their results.
You will need a variety of plastic easter eggs, you can buy them in bulk
online, for example at http://www.orientaltrading.com/ or at most local
stores in smaller quantities, as well as plastic colored manipulatives
to place inside the eggs.
You will need to prepare 12 eggs per lab group, the color combinations
and their contents are described on the teacher page of the handout.
Once the students have filled in their genotypes and phenotypes, as well
as a punnett square, they open the egg to see if the plastic pieces
match the results that they came up with. I gave detailed directions as
well as an example for how to fill in the worksheet.
Here is a link to the student worksheet and teacher answer key (pdf):

Here is a decription and link to the original lesson:
"This is a small activity to do immediately following your introduction
to the concepts of dominance, recessiveness, related vocabulary and
Punnett Squares. It uses different colored halves of plastic eggs to
reinforce these concepts in a quick, fun and memorable way."

If you have used this lesson, drop me a line and let me know how it
went! I would love to hear from you!
Have a great week!
