Niobium is element number 41. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.
Nitration of Benzene to form Nitrobenzene
Number 7 on the periodic table, Nitrogen is the most abundant element in Earth's atmosphere. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.
This is a step-by-step timetable for the Nobel Prize Lesson about a 2018 Nobel Prize. This lesson package consists of four parts: a slide show with a speaker’s manuscript for the teacher, a student worksheet, two short videos and this teacher’s guide. The lesson is designed to take 45 minutes.

We don't know much about Nobelium because it is does not occur naturally... But we know plenty about the famous scientist it is named after. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.
The video resource "Nomenclature - Crash Course Chemistry #44" is included in the "Chemistry" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.
The force that keeps a block of ice from falling towards the center of the earth
How the normal force changes when an elevator accelerates
Whether the normal force balances the force of gravity for a frozen sock or banana
Celestial navigation is the art and science of finding one's geographic position by means of astronomical observations, particularly by measuring altitudes of celestial objects sun, moon, planets or stars. This activity starts with a basic, but very important and useful, celestial measurement: measuring the altitude of Polaris (the North Star) or measuring the latitude.
Students create and use their own simple compasses, which are each made from a bowl of water, strong magnet, stick pin and Styrofoam peanuts. They learn how compasses work and about cardinal directions. They come to understand that the Earth's magnetic field has both horizontal and vertical components.
Students learn how engineers navigate satellites in orbit around the Earth and on their way to other planets in the solar system. In accompanying activities, they explore how ground-based tracking and onboard measurements are performed. Also provided is an overview of orbits and spacecraft trajectories from Earth to other planets, and how spacecraft are tracked from the ground using the Deep Space Network (DSN). DSN measurements are the primary means for navigating unmanned vehicles in space. Onboard spacecraft instruments might include optical sensors and an inertial measurement unit (IMU).
Students expand upon their understanding of simple machines with an introduction to compound machines. A compound machine a combination of two or more simple machines can affect work more than its individual components. Engineers who design compound machines aim to benefit society by lessening the amount of work that people exert for even common household tasks. This lesson encourages students to critically think about machine inventions and their role in our lives.

Paul Andersen explains how nuclear energy is released during fission of radioactive uranium. Light water reactors, nuclear waste, and nuclear accidents are also discussed along with the future of nuclear energy.
Nuclear Energy Explained: How does it work? Nuclear Energy is a controversial subject. The pro- and anti-nuclear lobbies fight furiously, and it's difficult to decide who is right. So we're trying to clear up the issue - in this video we discuss how we got to where we are today, as the basis for discussion. Next week we'll be looking at the arguments for and against nuclear power in detail. The video "Nuclear Energy Explained: How does it work? 1/3" is a resource included in the Physics topic made available from the Kurzgesagt open educational resource series.
Students learn about nuclear energy generation through a nuclear power plant virtual field trip that includes visiting four websites and watching a short video taken inside a nuclear power plant. They are guided by a handout that provides the URLs and questions to answer from their readings. They conclude with a class discussion to share their findings and reflections. It is recommended that students complete the associated activity, Chernobyl Empathy, before conducting this lesson; doing this assists students in gaining an understanding of how devastating nuclear meltdowns can be, which underscores the importance of careful engineering.
