ScienceSanner Snertal and Flirtal the Turtle
The purpose of this activity is to teach, and differentiate between, phenotype and genotype. Some other concepts introduced are: filling in and using Punnett Squares; the terms homozygous dominant, heterozygous, homozygous recessive; probabilities.
In this activity, students will: color turtles according to a description, identify the phenotypes of the turtles, use a chart to determine possible genotypes of the turtles, use Punnett Squares to cross the turtles, color the offspring according to random probabilities from the Punnett Squares.
I use Snertal and Flirtal the Turtle first, then I do Fish Eye Probabilities, then Bunny Rabbit Genetics.
