The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture
Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...
Space Awareness
Britannia Rule the Waves
Could you determine longitude based on measuring time? Early explorers used a longitude clock to do just that. Scholars learn about early exploration and the importance of the invention of the clock. Then pupils build their own longitude...

Why Can’t I Eat This Fish?
Can turning on the television lead to toxins in the food supply? The lesson offers an opportunity for young scientists to complete guided research. A worksheet lists each question as well as the web page necessary to answer the question....
Curated OER
The Lighter Side of Color
Students explore light and color, including how colors are mixed to produce new colors, how light is filtered, and how light is reflected off of surfaces. They read materials provided, complete worksheets, and complete hands-on activities.
Curated OER
Taking Action
Students use the net they make to dip macroinvertebrates at or below the surface. The flat side of the net allows pressure on the substrate so that organisms do not escape under the net. Two students hold onto the handles and submerge...
