How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...

You may not know if that zebrafish in your fish tank is a model citizen—but it is definitely a model organism! What can we learn about ourselves from a tiny zebrafish? Discover more about the polygenic trait of skin color through a...

Genetic analysis has gone to the dogs! Learners use real DNA information collected from dog saliva to study the relationship between genotypes and phenotypes. They analyze alleles to determine correlations to coat color, length, and...

Four intriguing and scientific activities invite learners to explore the natural resources of their town. The activities cover concepts such as genetic traits, organizing species in a taxonomy, the differences between different species...
