Waves Science Classroom Poster - EXTRA LARGE 33” x 23.5” - Gloss Paper - STEM Middle & High School Class Decoration - Wall Charts by Daydream Education.

Works perfectly in a classroom

I am impressed with the quality of the poster. It has the information that is relevant to my sons school work (Year 7) and he finds it and the others I purchased very useful for doing his homework and as a reminder of the principles of the subject. The diagrams and explanations are clear and he has had no problem in understanding them.
