Product Overview
Bring two essential fourth- and fifth-grade science topics together in one coordinated set: Waves: Sound and Light alongside Simple Machines. These matching 12x18 inch educational posters turn complex concepts into colorful, kid-friendly visuals that anchor any classroom wall, homeschool station, or science fair display. One poster illustrates how vibrations travel as sound waves and how light moves in straight lines, while the companion breaks down six simple machines—lever, pulley, wheel and axle, inclined plane, wedge, and screw—with clear diagrams and real-world examples. PosterEnvy prints both posters on durable paper in the USA using solar-powered production, so they stay bright through years of daily lessons and student questions.
- Display the full set of two 12x18 inch posters side-by-side to create an instant science corner covering both wave energy and simple machines.
- Watch students connect the dots between sound vibrations, light rays, and the six simple machines that make work easier every day.
- Printed on heavy-duty paper in the USA by a family-owned, solar-powered shop with over twenty years of classroom experience.
