Learn about all about fish in this video for kids! Fish are amazing water animals that are vertebrates (they have a spine) and have gills (which means they can breathe underwater!). This is going to be awesome!!


Special thanks to Chris 73 for the image of the gills. This image is freely available on Wikipedia.

Many of California’s K–12 students are English Learners. Some have been in US schools since kindergarten, while others are new to US schools and may be refugees or unaccompanied minors. Laura Hill, a senior research fellow at PPIC, and Megan Hopkins, an assistant professor of education studies at the University of California, San Diego, summarize new research on academic progress among English Learners in middle school and high school and the factors associated with their successes and struggles.

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.

For free. For everyone. Forever. #YouCanLearnAnything

This physics video tutorial explains the concept of sound waves and how shows you how to calculate the wavelength, frequency, and velocity of sound waves. It also shows you how to calculate sound intensity, intensity level in dB or decibels, beat frequency, and how to solve problems with open and closed organ pipes / tubes plus the doppler effect. This video contains the formulas and equations that you need for this chapter / topic as well as many examples and practice problems.

This Hubblecast Light highlights the exciting discovery of the first water detected on a potentially habitable planet. With data from the NASA/ESA Hubble Space Telescope, water vapour has been detected in the atmosphere of a super-Earth with habitable temperatures by University College Longon (UCL) researchers.
