Join us for the second video in our diversity series on Circle Time with Khan Academy Kids. Today, we welcome back Teacher Naomi and her son Noah who help explain the concepts of identity and race. Learn how scientists and society sometimes study and group people based on similarities. Then, listen to the difference between grouping in a good way (to build community) versus grouping in a bad way (racism). Getting to know people, rather than making judgments about skin color, is an important step in building a healthy community.

Continue the conversation with Caroline and Sophie as they talk about similarities and differences, like where they’re from, how they speak, and their family customs and traditions. Then read along to the story “Got to Be Me” by Cynthia Platt. Meet T-Rex the dinosaur who dared to be different. Finally, enjoy a diverse selection of artwork made by friends around the world!

This video is the second in a series that explains the values of diversity, race, and justice to young children. Our special guest, Naomi O’Brien, is a teacher, author, mother, and advocate for social justice. Learn more about Naomi at https://readlikearockstarteaching.com/.

The series is aligned with the guidelines for anti-bias education from the National Association for the Education of Young Children. NAEYC curriculum goals include helping to develop a child’s positive personal identity, empathy towards others, and the awareness of fairness.

We’d love to hear your child’s story. Send their pictures or drawings to our team at http://khan.co/KhanKids-SubmitYourArt. When we hear more stories, we have more to share and celebrate!

In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices.

In the Brønsted–Lowry definition of acids and bases, an acid is a proton (H⁺) donor, and a base is a proton acceptor. When a Brønsted-Lowry acid loses a proton, a conjugate base is formed. Similarly, when a Brønsted–Lowry base gains a proton, a conjugate acid is formed. A Brønsted–Lowry acid (or base) and its conjugate base (or acid) are known as a conjugate acid–base pair.
