11c. The Inca Empire: Children of the Sun
Conditions of Use:
No Strings Attached
Rating

The Inca called their empire Tahuantinsuyu, or Land of the Four Quarters. It stretched 2,500 miles from Quito, Ecuador, to beyond Santiago, Chile. Within its domain were rich coastal settlements, high mountain valleys, rain-drenched tropical forests and the driest of deserts. The Inca controlled perhaps 10 million people, speaking a hundred different tongues. It was the largest empire on earth at the time. Yet when Pizarro executed its last emperor, Atahualpa, the Inca Empire was only 50 years old.

27a. The Crowning of King Cotton
Conditions of Use:
No Strings Attached
Rating

Removing seeds from newly picked cotton is not as simple as it sounds. Cotton is sticky when removed from the plant, and pulling the seeds from its grasp is difficult. Throughout the 1700s, cotton production was expensive because of the huge amount of labor necessary to remove the seeds. All was changed with the invention of the cotton gin. What once was painstakingly slow was now relatively fast. By the end of the 18th century, demand for cotton was increasing as power looms were able to turn out great quantities of cloth. With the cotton gin, southern cotton plantations could now supply the world's demand.

Topography - Design Challenge
Introduction - Expanded learning opportunities (ELOs) have the potential to be the great equalizer in American education. Regular participation in high quality before and afterschool learning, and enriching summer school programs have been shown to help low-income students succeed academically on par with their more affluent peers. These programs, characterized by strong school-community partnerships, can also help high-performing students stay engaged and achieve even greater levels of understanding. In short, high-quality ELOs are for everyone - and the benefits they create are critical to Nebraska's future economy. - Beyond School Bells I would like to thank Beyond School Bells as well as Nebraska Innovation Studio for providing me with the opportunity, resources, and encouragement to develop this program as an Innovation Fellow. Their willingness to give the intellectual and creative freedom to build upon my ideas and inspirations is what enabled this program to exist. I strongly believe that opportunities such as the Innovation Fellowship are planting the seeds for Nebraska's future. -Dana Hoppe, Program Creator

Concept and Purpose - Interdisciplinary Learning: This program is focused on developing fundamental STEM skills through interdisciplinary learning. The truth is that all areas of study overlap significantly in one way or another, and the cognitive skills that lead to success in one area surely extend to other areas. A recurring theme I have noticed through my personal experience of being and artist as well as a scientist is that I have heavily utilized my creative thinking abilities to solve challenging problems. Imagination and creativity, when combined with background knowledge and understanding, allow us to find solutions that often lie beyond the rigid structure often associated with mathematics and the sciences. Once we begin to see the overlap between these areas, we begin building bridges between them and new ideas and applications emerge from a formerly empty space. The concept of topography was always interesting to me. The strangeness of being able to discern the shape of the land simply from the distance between a hypnotizing assortment of lines on a flat piece of paper was immediately intriguing. How does this flat sheet of abstract shapes translate to the three-dimensional complexity of a mountain, a valley, or a bluff? Topography is the platform of this program because it is a very versatile concept and can be used to create art and models representing a diverse range of fields. The activities in this program focus on having the students follow processes often found in Computer Science. Every process they complete can be thought of as an algorithm, and when they repeat steps, it can be thought of as a loop. They are also recursively calling the same function on each resulting piece they create, mimicking the concept of dynamic programing. The permutation matrix activities will familiarize students with moving through the data in a matrix and adding data to stacks. While they are doing all of these activities, however, there will be no jargon they have to learn, and they will probably not even realize until they take their first Computer Science course that it is even related. To the students, they will simply be creating art in a new and interesting way.

5b. Indentured Servants
Conditions of Use:
No Strings Attached
Rating

The growth of tobacco, rice, and indigo and the plantation economy created a tremendous need for labor in Southern English America. Without the aid of modern machinery, human sweat and blood was necessary for the planting, cultivation, and harvesting of these cash crops. While slaves existed in the English colonies throughout the 1600s, indentured servitude was the method of choice employed by many planters before the 1680s. This system provided incentives for both the master and servant to increase the working population of the Chesapeake colonies.

5d. Debtors in Georgia
Conditions of Use:
No Strings Attached

The development of Georgia was unlike all the other British colonies. First of all, it was the last to be created. Georgia was founded in 1733, 126 years after Jamestown was successfully planted. England and Europe as a whole were in the midst of an intellectual revolution known as the Enlightenment. Enlightened thinkers championed the causes of liberty and progress. Many believed in the innate goodness of human beings. They asserted that even the worst elements of society might prosper if given the right set of circumstances. James Oglethorpe was such a thinker. He and a group of charitable investors asked King George for permission to create a utopian experiment for English citizens imprisoned for debt. England's prison population could be decreased, and thousands of individuals could be given a new chance at life. With these lofty goals, Georgia was created.

Acidic Oceans Prompt Evolution
Conditions of Use:

It's no secret that greenhouse gases warm the planet and that this has dire consequences for the environment whole islands swallowed up by rising seas, animal and plant species stressed by higher temperatures, and upsets in ecological interactions as populations move to cooler areas. However, carbon dioxide has another, less familiar environmental repercussion: making the Earth's oceans more acidic. Higher levels of carbon dioxide in the atmosphere mean that more carbon dioxide dissolves in the ocean. This dissolved carbon dioxide forms carbonic acid the same substance that helps give carbonated beverages their acidic kick. While this process isn't going to make the ocean fizzy anytime soon, it is introducing its own set of challenges for marine organisms like plankton and coral.

This lesson will tie into the Nebraska science standards below. Students will learn how to search Worldbook KIDS online to study different animals and plants, as a class and independently. With a teacher’s help, students will then learn about animal and plant adaptations that help them survive in their habitats in order to come up with a solution to a human problem. The standards in bold print are the ones that will be the classroom teacher’s focus, but the librarian’s goal will be to introduce students to Worldbook KIDS as a reference source.It can easily be adapted to be a whole unit. Please let me know if you would like to help/edit this lesson to enhance it!
