So, what would happen if you dropped a hammer and a feather at the same time, from the same height? Well, the hammer would hit the ground first, right? But why? You might think it's because the hammer is heavier, or has more mass than the feather. But it's actually not because of that at all. In this episode of Crash Course Kids, Sabrina shows us that the rate at which things fall to Earth has to do with something called air resistance.

By tracing the movement of radiation released during an accident at the Chernobyl nuclear power plant, students see how air pollution, like particulate matter, can become a global issue.

This lesson provides teachers with support for using text-dependent questions to help students derive big ideas and key understandings while developing vocabulary from the series of poems, Danitra Brown Leaves Town. Danitra and Zuri are two city-girls and best friends, and Danitra goes away to her auntĺ䁥_s house for the summer. These poems tell a story about how the girls stayed in touch by writing letters to each other, and how they discovered that they could have fun apart from one another while still remaining friends.

The purpose of this task is to help students explore the meaning of fraction division and to connect it to what they know about whole-number division.

Ghyslain Raza, le « Star Wars Kid », sort du silence afin de réfléchir à notre soif de contenu et au droit à l’oubli à l’ère numérique.

Il existe une mini-leçon pour cette sélection qui se trouve sur ce site.

"Chaque année, l’École nationale de ballet du Canada charge un.e artiste canadien.ne d’élaborer une chorégraphie qui reflète un thème réfléchi.

Créée par Kimberley Cooper, Eugene Baffoe, Tracee Smith et Roger Sinha, la Chorégraphie Dansons Ensemble avec l’ÉNB de 2023 célèbre le pouvoir de la collaboration ainsi que la diversité et le dynamisme des artistes danseurs canadiens. La chorégraphie originale a été créée en 2017 dans le cadre d’un projet Signature pancanadien à l’occasion de Canada 150, et nous nous réjouissons de présenter, cette année, une nouvelle version de cette œuvre. Des vidéos incluant des instructions détaillées vous guident tout au long de la chorégraphie, que vous souhaitiez investir dans l’apprentissage et l’exécution de l’œuvre complète, ou que vous préfériez explorer seulement une petite partie du matériel.

La chorégraphie est créée en amont de la Journée Dansons ensemble de l’ÉNB, un événement festif national axé autour de la danse qui réunit des dizaines de milliers de personnes issues de communautés à travers le pays."

John Green teaches you about the so-called Dark Ages, which it turns out weren't as uniformly dark as you may have been led to believe. While Europe was indeed having some issues, many other parts of the world were thriving and relatively enlightened. John covers European Feudalism, the cultural blossoming of the Islamic world, and the scientific and artistic advances in China, all during these "Dark Ages." Along the way, John will raise questions about the validity of Europe's status as a continent, reveal the best and worst years of his life, and frankly state that science and religion were once able to coexist.

Propaganda! Misinformation! Disinformation! Today we’re talking about the dark – or, shall we say, darkER – side of media. Understanding these media bogeymen is essential to being a more media literate citizen.

Using two different coins and recording the results of both coins helps students dispel this initial misconception as they analyze the graph results. Class discussion should focus on analyzing the data to determine if the game is fair or not. Directions and gameboard are included in the download.

These activities support students as they conceptually develop a sense of how probability affects the outcome of games. Students will find that applying their knowledge of probability will help them win some of the games

During the last sunspot cycle between 1996-2008, over 21,000 flares and 13,000 clouds of plasma exploded from the Sun's magnetically active surface. These events create space weather. Students will learn more about space weather and how it affects Earth through reading a NASA press release and viewing a NASA eClips video segment. Then students will explore the statistics of various types of space weather storms by determining the mean, median and mode of a sample of storm events. This activity is part of the Space Math multimedia modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school textbooks. The modules cover specific math topics at multiple levels of difficulty with real-world data and use the 5E instructional sequence.

There are resources for two activities 1. Cryptograms: These puzzles are familiar sayings that have been encrypted. Use letter frequencies, letter patterns and your best analytical skills to decode these familiar puzzles that can be found in many puzzle magazines or online. 2. Crypto-lists: These lists were designed to introduce students to code-breaking. Each list contains words that relate to the topic. Use letter frequency and your best analytical skills to decode these lists. Remember that each list uses a different code to encrypt all of the words in that list. Hint: use tally marks to record frequency of each letter in the coded list, then use letter frequency information to break the code. Each activity includes an answer key.

"These three free digital courses introduce students to what data science is and why it matters. Through interactive exercises, students explore foundational data science knowledge, including collecting, visualizing, and understanding data. Data Science Foundations is the 101-course with two extension opportunities in the form of a Financial Wellness and Banking Fraud simulation."
Includes 3 courses:
*foundations
*financial wellness
*banking fraud

Today we’re going to talk about on how we organize the data we use on our devices. You might remember last episode we walked through some sorting algorithms, but skipped over how the information actually got there in the first place! And it is this ability to store and access information in a structured and meaningful way that is crucial to programming. From strings, pointers, and nodes, to heaps, trees, and stacks get ready for an ARRAY of new terminology and concepts.

This task asks the students to solve a real-world problem involving unit rates (data per unit time) using units that many teens and pre-teens have heard of but may not know the definition for. While the computations involved are not particularly complex, the units will be abstract for many students.

The first video in our database lesson, part of the Introduction to Computer series.
This video looks at the basics of databases. We define database, as well as key terms to know.

Database Management Systems is the software that allows us to create and use a database. This video looks at the DBMS, their functions, some examples of popular software solutions and a quick look at Structured Query Language (SQL)

The database management software is the program used to create and mange the database. The database model is the architecture the DBMS used to store objects within that database.

Our final database video. This one looks at some odds and ends. We examine: Data Warehouse, Data Mining, Big Data. I also talk about the ethics of data mining from the NSA and CDC, and how they are different.

We also give out top picks for the lesson.

On the leading edge of agricultural technology, young farmers are using data to minimize costs and improve yields while protecting their soil and water.
