In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

Can evolution repeat itself? Scholars analyze amino acid data in two separate populations of mice. They learn that evolution repeats itself, but natural selection prefers some mutations over others in different environments. Analysis...

While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

More than half the world's population eats rice as a daily staple ... imagine if that rice could prevent illness. Scientists genetically engineered rice to include vitamin A for just that purpose. However, room for debate still exists....

Ninth graders complete a monohybrid cross and a dihybrid cross. In this biology instructional activity, 9th graders predict the traits of offspring using the Punnett square. They differentiate recessive and dominant genes.

Many physicals include a blood glucose test, but what are doctors actually testing? Scholars graph and interpret blood glucose data, allowing them to observe the differences in lactase persistence and draw conclusions. They then connect...

Students read an article about how honeybee are sensitive to the electromagnetic fields generated by cellphones. For this ESL lesson, students work as partners to complete a table of information relating to the many bee species in...
