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...

The Hardy-Weinberg principle states that alleles and genotypes remain constant in the absence of evolutionary influences. Scholars complete a simple hands-on activity applying the Hardy-Weinberg principle to sample data. They observe how...

Students investigate Mendelian Genetics by studying the history of Mendel and what it was like to be a 19th century scientist. They read a pieces of fiction during this investigation.

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...

Take your biology class' understanding of biodiversity to a whole new level! Ecology scholars use data to calculate three different diversity indices based on the organisms in the Gorongosa National Park. The four-part activity uses an...

Students set up and run the experiments they designed in the activity, 'Population Growth in Yeasts,' using simple yeast-molasses cultures in test tubes. They demonstrate understanding that several environmental factors can contribute to...

Fourth graders represent a new predator on a population of colored worms. They mathematically determine the effect of the new predator on the survival and reproductive rates of the worms, simulating natural selection at work.

Students engage in a study of science and mathematics with the practice of creating graphs. A guest speaker comes to the class to share statistics from the community and the students are shown how he uses the coordinate system in the...

How quickly do animals evolve? Can comparing different samples of the same fossil answer timeline questions? Scholars use virtual labs to examine fossils and learn about stickleback evolution. They compare pelvic morphology in lakes...

Based off of the hit television show NUMB3RS, this lesson shows students the scientific reasoning behind the societal taboo of incest. Students complete a Punnett square to determine the chances of an offspring inheriting two recessive...
