Project has two main meanings, pronounced differently:

When you project something (pruh-JEKT), you're sending it outward or forward. A movie projector projects images onto a screen by beaming light through film. When you speak to a large audience, you need to project your voice so everyone can hear you clearly, even in the back row. Scientists project future trends by using current data to predict what might happen: a weather forecaster might project that tomorrow will be sunny, or a biologist might project how a population of wolves will grow over the next decade.

A project (PRAH-jekt) is a planned piece of work with a specific goal and usually a deadline. You might work on a science fair project about volcanoes, or your parents might tackle a home improvement project like building a deck. Good projects have clear objectives: you know what you're trying to accomplish and when you need to finish. A project might take a few days or several months, but it always involves planning, effort, and working toward something specific. The word suggests something more substantial than a quick task: building a birdhouse is a project, but hammering in a single nail isn't.
