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!

In this episode of Kids Teach, K12 CEO James Rhyu tees up with student, entrepreneur, and golf phenom Carter Bonas for some lessons on the green. While James improves his drive, they share insights about what drives each of them to excel. They talk about their shared passion for providing education solutions: James through his leadership role at K12, and Carter through his non-profit start-up, Spectrum Golf.

Through the course of their discussion, it’s clear that, despite Carter’s youth, his teaching is on par with the best! James also offers some executive mentorship in exchange.

This is just one example of how rewarding a knowledge exchange between learners of any age can be. Throughout the Kids Teach series, we’ll highlight talented students teaching adults some new skills. Follow along and learn with us!

The ocean is vital to our planet because it produces over half of the world's oxygen supply. It also absorbs 50 times more carbon that the atmosphere. We can also turn to the ocean for food, transportation, and recreation. In addition, the ocean helps regulate weather patterns, creates employment opportunities, and provides ingredients for medicines.

We hope you and your student(s) enjoyed learning about the world's beautiful ocean! If you want to learn even more, head over to our website and download one of our many lesson plans about the ocean, full of activities, worksheets, and more!

#ImportanceOfOceans

Student pairs design, build, and test model vehicles capable of rolling down a ramp and then coasting freely as far as possible. The challenge is to make the vehicles entirely out of dry pasta using only adhesive (such as hot glue) to hold the components together. Creativity is encouraged and different types of pasta are provided to support different functions such as round pasta for wheels and sheet pasta for the chassis. Students become familiar with the concepts of gravitational potential energy, kinetic energy and rolling resistance. Teams follow the steps of the engineering design process as they design, test and redesign their small-sized vehicles, working within the project's material constraints. The winner of the competitive final event is the pasta car that travels the longest distance beyond the bottom of the ramp.

NOTE: We would like to correct an error in this video. Birds do not get electrocuted when resting on power lines because there is no path to ground. Electricity has to flow from a place of high potential to low potential to electrocute. If a bird were to touch the line and some grounded metal of some kind, they could be shocked.

Hello Teachers and Parents! In this video we will learn all about electricity. Your student(s) will learn about lightning, power plants, Direct Current (DC) and Alternating Current (AC). We even talk about when electricity was discovered and go over topics like conductors and insulators. By the time you are done watching this video your child will have a much better understanding of what electricity is, where it comes from, and the amazing things it can do.

We know that electricity can be a tricky topic to cover so throughout the video we provide really good examples and break down the complex ideas. We also have a complete lesson plan full of worksheets and activities that will help your student practice what they are learning. You can download for free here: https://learnbright.org/lesson....s/science/electricit

In this video we will learn:
0:00 What is Electricity?
1:38 What is a Direct Current?
4:13 What is an Alternating Current?
5:55 How do Power Plants produce Electricity?
6:51 How do Magnets create Electricity?
7:33 What is Static Electricity?
8:35 What is a Conductor?
9:08 What is an Insulator?
10:21 When was Electricity Discovered?

If you've seen footage from the International Space Station or any of the space shuttle missions, you know that astronauts float around as they orbit the Earth. Why is that? Is it because the gravitational force on them is zero in space? (Or nearly zero?) The truth is that the strength of the gravitational attraction is only slightly less than it is on Earth's surface. So how are they able to float? Well, they aren't floating - they're falling, along with the space station. They don't crash into the Earth because they have a huge orbital velocity. So as they accelerate towards the Earth, the Earth curves away beneath them and they never get any closer. Since the astronauts have the same acceleration as the space station, they feel weightless. It's like being in a free-falling elevator (without the disastrous landing).

Welcome back to The Maths Guy

This is lesson 4 in our 10 part lesson series to teach you everything you need to know in Year 5 Maths.

This lesson focusses on Fractions. Fractions are an essential part of Year 5 maths and play an important part of the progress you'll make in year 5

We will begin by looking at equivalent fractions, then we will look at ordering and comparing fractions before converting back and forth from mixed number fractions to improper. Finally we will finish this lesson looking at how to add fractions which will include all the skills we had in this lesson.
