8 Coding Project Ideas for High School students

As technology continues to reshape our world, it's natural to wonder about the origins of your favorite apps, websites, platforms, and technologies. In today's rapidly evolving tech landscape, the ability to code has risen as an indispensable skill, enabling anyone to transform their creative dreams into reality. This transformation finds its finest expression in coding projects — a conduit through which your previously acquired skills and knowledge seamlessly fuse into tangible, functional products! The coding projects in this article cater to a spectrum of skill levels, ensuring that both beginners and advanced have interesting projects to work on.

Beginners will find projects designed to introduce fundamental concepts, guiding them through the essentials of coding, logic, and algorithmic thinking, and as the difficulty increases, more and more concepts, technologies, and coding languages will come into play. For this article, any of these projects can be implemented across a variety of languages, but we suggest C and Python, on top of the other languages that are directly stated.

With that, here are 8 coding project ideas for high school students

1. Simple Calculator App (Beginner)

A classic beginner project,  you can test out your coding skills to build a terminal-based calculator app. The project consists of you creating a basic calculator application that can perform arithmetic operations like addition, subtraction, multiplication, and division. Taking on this helps you practice fundamental programming concepts, such as taking in user inputs and running it through your code. As a high school student, your aim should not be to complete projects for the sake of, such as this one, but also ensure that the project you take on is complete and gap-proof in every sense. Here are some markers of a complete project:

- Input Management: Handling an input of numbers, which arithmetic operations they want, handling a series of calculations until the user “presses equal”

- Error Handling: Non-numeric inputs, dividing by 0

2. Dice Rolling Simulator (Beginner)

This simple and fun project requires you to spend some time creating a program that simulates rolling dice. You can use this for board game nights, or even as a fun addition to your portfolio! You should ideally allow the user to input the number of dice and the number of sides on each die, and then display the results of the rolls. This project helps you practice random number generation and basic user input/output. 

A few things to consider while working on a dice stimulator include user interface design, by having a display of the dice rolls and rolling button, proper functionality, with random number generation and displaying results, and the user experience, by implementing visuals of the dice roll and to reset the project.

The skills you will need is knowledge of basic logic and control structures in Python – you'll need to use conditional statements to handle user interactions and display the results of the dice rolls.

3. Number Guessing Game (Intermediate)

The next project has you developing a number guessing game where the computer randomly selects a number and the user tries to guess it. Add features like giving hints and keeping track of the number of attempts. This part is where the code gets a little tricky, because now the program must comprehend the user input and compare it with a randomly generated number. Here’s some things to consider and skills you should have to complete this project:

- Have a strong user interface with a display that shows the instructions

- Include a user input field, and restarting function

- Include proper functionality of actual random number generation and the ability to compare the user’s guess with the target number

- Include and improve upon user experience functionality by providing feedback on the guesses, and managing the state of the game (playing, win, lose).

4. Personal Portfolio Website (Intermediate)

A portfolio is important for any up-and-coming programmer,especially when you are applying to college. Admissions officers are looking for applicants who not only demonstrate interest in pursuing a particular skill at college, but have also worked towards developing it outside of school. Creating a personal website showcasing your skills, projects, and interests helps greatly with the above! Learning HTML, CSS, JavaScript, and more can add interactivity to your site. This project teaches you web development basics and can be scalable as you continue to grow your programming skills, advancing your website to be even more complex in the future. Developing your first website, especially your personal portfolio can be a productive way to dip your toes into the world of website development, and many people’s first interaction with HTML, CSS, and JavaScript.

5. Weather App (Intermediate)

You can build a weather application that uses an API to fetch real-time weather data for a given location and displays it to the user. In the course of completing this project, you'll learn about API integration and data visualization – two crucial skills for developing useful programs for people to use. Here’s some aspects and skills that are super important to have while working on a seamless, accurate weather app. . When it comes to focus on user interface and overall design, you should create an appealing interface with a clean layout of weather icons, temperature, windspeed, humidity, etc. To feed in weather data, integrate a weather API, such as OpenWeatherMap, WeatherAP to fetch real-time data.

Additionally, you can also implement location services – for the user to manually enter a location or detect their user’s current location (if the second, be ready to implement permissions and privacy related to location services). Lastly, you will get the chance to work on your data presentation to show current weather conditions that consistently update.

6. Basic Game using a Game Engine (Intermediate to Advanced)

While making a game may seem very complex, you can use a game engine like Unity to create a simple 2D game. This could be a platformer, puzzle game, or a top-down shooter. With this project, you’ll delve into game mechanics, physics, and game design principles. Handling multiple user inputs at the exact same time, collisions, game over and begin, and memory storage are some basic things you must consider, before even thinking about the design of the game. This is because there are many games out there, many different lists of items to consider, and many YouTube tutorials to build a game from scratch with Unity. A classic example of this is Google Dino Game.

7. E-commerce Website (Advanced)

If you have a good amount of experience with coding, here’s one project you should consider - design and implement an e-commerce platform where users can browse products, add items to their cart, and complete purchases. Now, before you get started, we suggest against processing actual payments and selling actual products. However, this ambitious project will still cover database management, user authentication, and tailoring your website and feed to each user. For any website, user interface is extremely important – you should:

- focus on creating an intuitive and visually appealing design that reflects the image you want to pursue

- implement a user-friendly navigation menu and clear categorization of products

- make sure the design works across various devices and screen sizes.

For the commerce side of the website

- display product images, titles, descriptions, prices, and availability

- implement a sorting algorithm to display products based on different criteria, such as price and popularity, and a search feature with the same sorting algorithm

- add detailed product pages with specifications, reviews, and related items

- create a simple checkout process with a functional shopping cart

- enable users to create accounts, log in, and manage their profiles, where then you can keep track of their order history.

Storing information from “users” and having such a dynamic website will require more skills than just basic Python programming, such as SQL and Flask, on top of every other aspect of a website.

8. Iris Flower Identification Machine Learning Project (Advanced)

As a high school student, machine learning and artificial intelligence are very popular projects for you to work on. Additionally, working on ML-based projects before college  showcases to the admissions officers your ability to stay updated with advancements in computer science. Dive into machine learning by working on a project like sentiment analysis for text, image classification, or even creating a recommendation system. There is such a wide range of different potential machine learning projects that we have covered here!

A very famous introductory ML project is iris flower identification is known as the “hello world” of machine learning – the first project to dive into this complex world. The project has you classify flowers based on their class: Versicolor, Setosa, Virginica, each with 4 features, Septal length and width, and Petal length and width. For a machine learning project, it is easy to classify a successful project: it must have functional code and a high accuracy!
