This activity focuses on the use of graphene in organic fibers, and their applications in organic electronics, e-textiles and wearable technologies. Students learn about the properties of graphene—a unique form of carbon—and how graphene-based fibers are fabricated, how to measure resistance, how to calculate resistivity, and how a material changes its electrical properties. Students also learn about the importance of defining design parameters, which is an important concept in the engineering design process. Students create graphite-based fibers using sodium alginate as the medium and a calcium coagulation bath, which is similar to the way in which graphene-based fibers are created in engineering research laboratories. Students then determine the factors that contribute to resistivity and vary these parameters to optimize fiber resistivity.

En este nuevo vídeo para aprender español, veremos 1 día en la vida de nuestro superhéroe.

En esta clase aprenderemos como hacer un relato en primera persona, con nuestro superhéroe como protagonista.

El narrador en primera persona cuenta una historia desde el "yo" o "nosotros". Los verbos se conjugan en la primera persona gramatical, por ejemplo: " Me pongo los pantalones"

Nuestro superhéroe nos relata en primera persona un día de su vida y todas las acciones que realiza desde que se levanta.

Una buena oportunidad para aprender a relatar en primera persona, a conjugar los verbos y un montón de vocabulario del día a día.

Además nuestro superhéroe conversa un poco con su loro, lo que nos permitirá aprender un poco de diálogos y el nombre de algunas frutas.

Concluding a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate densities of several household liquids and compare them to the densities of irregularly shaped objects (as determined in Part 1). Then they create density columns with the three liquids and four solid items to test their calculations and predictions of the different densities. Once their density columns are complete, students determine the effect of adding detergent to the columns. After this activity, present the associated Density & Miscibility lesson for a discussion about why the column layers do not mix.

In this video I break down the growing synergy between AI and crypto, revealing why this might be the best time to explore AI-driven altcoin ecosystems—even if the market seems to be moving sideways. I’ll show you how these technologies share a “love it or hate it” energy, and why early adoption could lead to major opportunities. Plus, I’ll discuss what to watch out for: from spotting scam projects to understanding data ownership, decentralization, and scalability. Whether you’re an AI enthusiast, a crypto investor, or just tech-curious, this video gives you essential insights into the real-world use cases that are driving innovation. Remember, I’m not a financial advisor, so always do your own research before diving in.

Using paper, paper clips and tape, student teams design flying/falling devices to stay in the air as long as possible and land as close as possible to a given target. Student teams use the steps of the engineering design process to guide them through the initial conception, evaluation, testing and re-design stages. The activity culminates with a classroom competition and scoring to evaluate how each team's design performed.

The fastest animal in nature isn't what you think it is. It's way, way smaller than that. Nature's tiniest creatures warp the laws of physics, and they do it in ways that even human engineers would gawk at. Using the power of super slow-motion macro video, let's uncover the biological engineering that lets nature's fastest creatures do their zoomy thing.

En este nuevo vídeo para aprender español gratis, aprenderemos los diminutivos en español.

Los diminutivos son una forma de decir que algo es pequeño, por ejemplo, en lugar de decir que era "una plaza pequeña" puedes decir que era "una placita", lo que te ayudará a mejorar tu nivel de español y hablar como un nativo.

Este es el uso más común de los diminutivos, pero también se utilizan, en menor medida, para expresar cariño, como por ejemplo "iré a la fiesta con mi cariñito".

La forma más común del diminutivo es agregando "ito" o "ita" al final de la palabra (sufijo), como veremos en el vídeo.

Pero también hay otras formas de diminutivo, menos utilizadas, por ejemplo:

illo - illa:
¿Tienes un palillo para los dientes?
Pobrecilla, no vió que el piso estaba mojado

Otro uso común del diminutivo es para referirse o llamar a los niños pequeños, adicionando el "ito" o "ita" al final del nombre. Veremos también ejemplos de este uso en el vídeo.


Listado de diminutivos que veremos en el video con ejemplos:

00:00 Diminutivos en español
00:02 La casa – la casita
00:35 La oveja - la ovejita
01:20 El gato - el gatito
02:07 El árbol - el arbolito
03:03 La mesa – la mesita.
03:49 El caballo – el caballito.
04:24 El conejo – el conejito
04:57 El uso de diminutivos en los nombres propios
05:11¿Cómo se hace el diminutivo?
05:29 Pablo – Pablito.
05:52 Marta – Martita.
06:24 El pájaro – el pajarito.
06:50 La bolsa – la bolsita.

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. 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. Don't let these big words intimidate you. We're on this journey with you!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Students investigate the weather from a systems approach, learning how individual parts of a system work together to create a final product. They learn how a barometer works to measure the Earth's air pressure by building a model using simple materials. Students analyze the changes in barometer measurements over time and compare those to actual weather conditions. They learn how to use a barometer to understand air pressure and predict real-world weather changes.
