Students are given a history of electricity and its development into the modern age lifeline upon which we so depend. The methods of power generation are introduced, and further discussion of each technology's pros and cons follows.

Students will explore hybridization, selective breeding and genetic Physical Science through a jigsaw approach. Then they will go through a series of articles that help them formulate their own opinions about genetic manipulation. Lastly, they will debate the merits of genetic manipulation as a class.

Students will construct an argument based on evidence regarding their position on genetically modified organisms (GMOs). Students will conduct an inquiry investigation in Mendelian genetics using Wisconsin Fast Plants.

In this video collaboration from Khan Academy and 23andMe, you'll learn about the basics of cells, chromosomes, and the genes contained in your DNA.

In this video collaboration from Khan Academy and 23andMe, you'll learn about the variations in human DNA called SNPs, and how they can be used to understand relationships between people.

In this video collaboration from Khan Academy and 23andMe, you'll learn how your observable traits, or phenotypes, are the result of interactions between your genes and environment.

In this video collaboration from Khan Academy and 23andMe, you'll find out why women don't have a Y chromosome. Even with no Y, women can still learn about their paternal ancestry with genetic testing from services like 23andMe.

This lesson for English Language Learners (ELLs) introduces a famous Mongol warlord, Genghis Khan. In this lesson, learners will practice reading, listening, speaking and writing. All activities are automatically graded with feedback provided to the learner upon submission.

This resource contains 9 lessons to get Genius Hour off the ground in your classroom.

Students read "The Jolly Postman", in which a postman delivers letters to storybook characters. They explore different types of mail and categorize letters from the book and their own mail. Children find favorite words, phrases, and sentences from familiar stories. Working together, they combine their words and phrases to create a poem. The poem is then shared as performance poetry.

This is an activity about the periodic reversals of Earth's magnetic field. Learners will graph the frequency of magnetic pole reversals over the past 800,000 years and investigate answers to questions using the graphed data. This is Activity 8 in the Exploring Magnetism on Earth teachers guide.

This is an activity about the movement, or "wandering," of our Earth's magnetic poles. The learner will explore this concept by measuring and calculating the distance the Earth's north magnetic pole has moved over the past 400 years and calculating the rate at which the magnetic pole location has changed its position during that time. Finally, learners will use this information to extrapolate how the region for viewing aurorae may change over the next century at the present rate of polar wander. This is Activity 6 in the Exploring Magnetism on Earth teachers guide.

Mathematicians often argue that anything which can be represented numerically or algebraically can also be represented geometrically. This is perhaps true even to the extent that simple numeric calculations can be demonstrated geometrically. This example illustrates one such geometric process of addition. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

In the first part of this video, we review the idea of flat space and the Pythagorean theorem. The second part of the video reviews ideas from trigonometry including the unit circle, sine, cosine, and pi. We conclude with a proof of an angle-sum identity.
