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.

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!

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.

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!

Pre-order our book YOU ARE AN ARTIST (which includes new assignments!) here: http://bit.ly/2kplj2h

Michelle Grabner is curator, critic, professor, and artist who works in multiple mediums, but much of her work centers around pattern and color. Her assignment asks you to recall an activity you may have done in kindergarten and explore it’s potential as a design project.

INSTRUCTIONS - PAPER WEAVINGS
1. Gather a sheet of paper to make cuts into
2. Gather other sheets of colored paper to cut into strips
3. Weave the strips into the base paper
4. Document your work and/pr your process. Upload using #theartassignment
5. Fame and glory (Your work might be in a future episode)

We then discuss Friedrich Froebel, the creator of kindergarten, that also utilized paper weavings in early childhood development.

There is some debate which should be taught first – UPPERCASE letters of lowercase letters. On the one hand, uppercase letters are easier to identify and draw. On the other hand, most of what is written is in lowercase.
Whichever order you choose, we have prepared this entertaining video for teaching uppercase letters. Cute animals, natural phenomena and your kids’ favorite foods will introduce letters to your little ones and help them learn their ABCs.
