We investigate the effect that unbalanced charge has on polar molecules. We rub a balloon against hair to build up a negative charge and then hold this near a stream of water and then a stream of treacle. They both bend towards the...

We use a Van de Graaff generator to investigate static electricity. The generator is turned on and we see a spark move between the two domes. We then place a wig on the main dome and see the hair rise as the charge builds and the hairs...

We use a disposable nappy to examine the superabsorbent properties of hydrogels. We add water to grains of hydrogel and watch them swell before adding salt to see the water escape. Chemistry - Chemical Industries - Learning Points....

Electrical polarity is the arrangement of positive and negative charge in an electrical circuit, or distribution of positive and negative charge in, for example, a chemical bond. A Twig Science Glossary Film. Key scientific terms defined...

Ever wondered how the motion of a conductor in a magnetic field generates voltage? We break it down with a real-world example of an airplane wing cruising through Earth's magnetic field. Don't worry; we keep it light and fun! Learn about...

In this video, you'll master bond dipoles in minutes – Chemistry Made Simple! 🌟 Dive into the fascinating world of bond dipoles and learn how to identify these crucial elements in various molecules. Understanding bond dipoles is...

The inductive effect can drastically alter how molecules behave in reactions. Electron-withdrawing groups can increase a molecule’s electrophilicity, making it more likely to accept electrons in a reaction. Conversely, electron-donating...

The inductive effect is all about how atoms in a molecule affect electron distribution. Electron-withdrawing groups, like halogens, pull electrons through sigma bonds, reducing electron density in adjacent atoms. Conversely,...

Nucleophiles, often referred to as "nucleus lovers," are chemical species that donate an electron pair to form a bond. They attack positively charged or electron-deficient atoms in a molecule, making them key agents in substitution and...

Explore the fascinating world of magnetic forces with Flipping Physics! In this engaging video, we delve into the right-hand rule, an essential tool to understand the direction of magnetic forces on moving charges. From positive charges...

Delve into the mass spectrometer, a crucial tool for understanding particles and their properties. Consisting of a velocity selector and a deflection chamber, it begins with charges entering the crossed fields of magnetic and electric...

Dr. Forrester defines static electricity by conducting a simple experiment using a balloon. She also identifies the two types of electricity by describing static electricity and current electricity.

This video explains how the different particles in an atom have charges, how the different particles affect the overall charges of an atom, and how atomic models are created.

The electric potential difference in a uniform electric field is derived and used to show lines of equal electric potential or equipotential lines. Equipotential lines and surfaces of point charges and dipoles are shown. The equation for...

We've all heard the terms acid and base. What do these mean? Don't just tell me about pH, silly. What structural detail makes a molecule an acid or a base? You don't know? Well, you'd better watch this then. You don't want to be...
