Longitudinal waves are waves in which the displacement of the medium is in the same direction as, the direction of propagation or movement of the wave. In other words, the displacement of the medium is parallel to the propagation of the wave

Longitudinal waves are also called compressional or compression waves, because they produce compression and rarefaction when traveling.
I also cover compressions and rarefactions.

Violet is a young snake who likes to play with the other animals in the forest. But when spring arrives, her friends get very busy making presents for Mother's Day. Violet is glad everyone's working so hard, but what can she do for her own mother? Without arms or legs or teeth, she can't make gifts as the other animals can. Then Violet discovers that there is one thing she can do that's different-and comes up with the most original gift of all!

Imagine an ocean where water is constantly boiling, it’s boundless, there is no coast in sight. It stretches as far as the horizon, although this fact is evasive to the observer, because as far as the eye can see the horizon is constantly shrouded in dense fog. Thick clouds with not a chink between them hide a huge, but dim sun. Only negligible fluctuations in the level of light indicate transitions from nights to days and nights again. If it has stopped being pitch-dark and it’s deep grey all around you, it means sunrise. And deep down, under scores of kilometres of water, there lies a billion-ton core of scorching ice. This is what the unique and mysterious world of Gliese 1214 b must look like.

We’ve found a new planet, home to octillions of the most extreme beings living in the most absurd and deadly hellscape. In absolute darkness, crushed by the weight of mountains, starved of oxygen, cooked alive, bathed in acid, salt or radiation. And yet, they live for thousands, perhaps millions of years! It turns out, this planet is not in space – it is inside the crust of Earth!
This is the deep biosphere and we basically learned that it exists yesterday. Its volume is at least twice as large as all the Earth’s oceans, home to more microbes than the rest of the entire planet.Their total biomass is more than 20 times greater than all humans, livestock, and animal wildlife.
Let’s descend into this mad, deadly world where none of the rules we thought are mandatory for life apply.

Join us for a discussion about diverse learners in K-12 schools. Listen in as our Education Solution Specialist, Theresa Goodlett hosts a discussion with ESL teacher Erin Sivek from Milwaukee Public Schools regarding her English learning program and experiences at Milwaukee Academy of Chinese Language.

Erin will talk about her challenges and triumphs with her English learning program, including:

Classroom approach and strategies for English learners.
How EL students are assessed and how to respond to the needs of students.
The approach to blended learning in the classroom.
We will also be exploring Fuel Education’s supplemental blended instructional curriculum developed by their partner, Middlebury Interactive Languages, which allows students in grades 4–8 to learn the fundamentals of academic English while completing projects that relate to English language arts, social studies, mathematics, and science.

How to integrate Social Studies and English Language Arts
Welcome to the Arizona Department of Education’s video on integrating social studies and ELA. In 2018 the Arizona State Board of Education adopted new social studies standards and gave time recommendations for elementary classrooms. With the push for extended ELA and math time this leaves little extra time for social studies. This video will show ways in which you can integrate social studies with ELA to maximize student learning and meet the time recommendations.

Here is a sample lesson pan template at my TPT store https://www.teacherspayteacher....s.com/Product/Lesson

Lesson planning is broken down into twelve different components that all school administrators, and state quality assurance for school will require. Most of these components you will already have in your lesson plans. Some of the categories that are required for teachers to have in their lesson plans begin with having a title and date for all of the lesson plans that are being submitted. Other required components for a teacher's lesson are including differentiated instruction for students with disabilities, and ell students. it also should include technology standards, state standards and cross-curriculum standards when they apply to the lesson. This video is part of a teachings in education playlist designed to help educators answer some of the many questions that teachers have throughout the school year. Other videos include teacher interview questions, blooms taxonomy, formative assessment, positive behavior intervention and supports, school climate and school culture, special education background knowledge, and many more. Teachers looking to add a little bit more to their classroom lesson planning can find a lot and really improve their practice through these videos. Remember, lesson planning is one of the most important components of teachings, yet many teachers don't put enough time into planning their lessons.

Test for the 6th Grade Vocabulary part 3 word list in English. Definitions appear and are read aloud. Breaks in the video with a PAUSE button allow the student enough time to react to each definition. Kids will love the interesting format and the less stressful learning.

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

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.
