Lactase Persistence: Evidence for Selection
What's the link between lactase persistence and dairy farming? Biology scholars analyze data to find evidence of the connection, then relate this to human adaptation. Working individually and in small groups, learners view short video...
Exploratorium
Persistence of Vision
Ahoy, matey! Peer through a special telescope to explore the persistence of vision. The telescope has only a thin strip with which to view the world, but as it scans the area, your eye and brain work together to create a complete...

Measuring the Vitamin C Content of Foods and Fruit Juices
Are you getting enough vitamin C? Young scientists determine the amount of vitamin C in fruit juice samples. They accomplish this task by adding DCPIP solution to the samples until the blue color of the DCPIP persists. Once this happens,...

The Making of the Fittest: Evolving Switches, Evolving Bodies
How did the stickleback fish, which was once ocean bound, evolve to be able to persist in freshwater lakes? Hear from the scientists who identified the genes and related switches that allowed these survivors to adapt. In addition to the...

Got Lactase? Blood Glucose Data Analysis
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...

Magic Wand
Pupils observe how an image falling on a CCD array is divided into individual pieces, by the property of persistance of vision.
Curated OER
Rainbow Spinner
In this rainbow spinner activity, students participate in making a rainbow spinner in order to investigate the splitting and mixing of light. Students study the theory of persistence of vision.

Got Lactase? The Co-Evolution of Genes and Culture
Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...
