Lesson details
Key learning points
- JavaScript can be used to change HTML content and styles dynamically to make web pages interactive.
- The Document Object Model (DOM) allows JavaScript to access and modify web page elements.
- Event listeners detect user actions (such as clicks and key presses) and trigger JavaScript functions.
- Functions in JavaScript allow us to write reusable code that updates and responds to user interactions.
Keywords
JavaScript - a programming language used to add interactivity to web pages
DOM (Document Object Model) - a representation of a web page that JavaScript can use to access and change HTML elements
Event listener - a function that waits for a user action (such as a click) and then triggers a response
Common misconception
JavaScript changes the original HTML file.
JavaScript only changes what the user sees in the browser. It does not change the actual HTML file saved on your computer or server.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.

When programmers write code, they use a special tool called an IDE (Integrated Development Environment). In an IDE, different colours are used to help programmers understand the code:
- • Blue - numbers and boolean values
- • Green - strings
- • Purple - keywords
