Accidentes y cómo llamar una ambulancia.

En este vídeo para aprender español veremos vocabulario sobre emergencias.

Reproduciremos un accidente ficticio y veremos la llamada a los servicios de emergencia y el típico diálogo con el operador del número de emergencias.

Un vídeo con vocabulario que puede serte muy útil algún día aunque esperamos que nunca lo necesitéis.

Juan tiene un accidente y es encontrado por su esposa inconsciente. María llama a los servicios de emergencia y tiene un diálogo con el operador.

Le pide que mantenga la calma y los datos necesarios para gestionar la emergencia. Además le dan instrucciones de lo que tiene que hacer con su marido hasta que llegue la ambulancia.

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

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.

This calculus video tutorial explains how to find the absolute maximum and minimum values of a function on a closed interval. Tto find the absolute extrema, you need to find the relative extrema by finding the first derivative of the function and the critical numbers. Plot the critical numbers on a number line to create sign chart. Using the sign chart and the first derivative test, determine what type of relative extrema is present - if it's a relative maximum or a relative minimum. Next, place the critical numbers and the endpoints of the closed interval into an x y data table and compare the y values. The absolute maximum contains highest y value and the absolute minimum has the lowest y value.

This acids and bases chemistry video tutorial provides a basic introduction into the calculation of the pH and pOH of a solution. This video explains how to the calculate the hydronium ion [H3O+] and the hydroxide ion [OH-] concentration given the pH or the pOH of the solution. This video contains the formulas and equations needed to calculate Ka and Kb using Kw as well as the pKa and pKb of acids and bases. This lesson contains plenty of examples and practice problems.

Lesson 36. Heavier and Lighter | Kindergarten Math | Math For Kids
TeCa creates online math courses for kids by grade level from K-5. All our math lessons are delivered through attractive videos, in which we extensively use visual images, graphics, animation and upbeat music to make kids excited about each and every lesson. We also have practice exercises for kids in each lesson to reinforce their understanding.
Our goal is to bring kids enjoyment in math learning, help them see the beauty of mathematics, and have a love for math from an early age. We believe teaching kids math in the right way gives them a head start in the subject, which is a strong foundation the development in other areas of education.
