Highlight the STEM process, scientific thinking, engineering design, and science inquiry with these posters that make a great science class bulletin board!

With 20 posters total, this resource is designed to help students develop the problem-solving, critical thinking, and inquiry-based skills that are at the heart of science, technology, engineering, and math. Each poster highlights a key step or skill, includes a clear definition, and features a representative image to make the concept easy to understand and visually engaging.

Every poster comes in two versions—full color for a bold classroom display and black & white for easy printing or student notebooks. Whether you’re teaching students to form a hypothesis, analyze data, brainstorm solutions, or improve their designs, these posters provide a consistent visual framework that reinforces the scientific habits of mind and engineering thinking your students need to succeed.

Perfect for elementary through middle school STEM classrooms, science labs, or maker spaces, these posters support both guided instruction and independent learning. Students will have a quick reference tool to help them stay focused on each step of the process, making it easier to internalize the cycles of questioning, testing, and refining ideas.

By integrating these posters into your classroom, you’re giving your students a daily reminder that science and engineering are creative, iterative, and hands-on. They don’t just learn the steps—they learn how to think like real scientists and engineers. A must-have for any STEM-focused learning environment!

Critical thinking is invaluable in science and STEM fields, and these 20 posters make it easy to reinforce critical thinking skills relevant to STEM fields! Each poster features a valuable scientific critical thinking skill.
