What’s on the How Sound Works poster
A definition and 6 facts worth remembering.
Sound is made when something vibrates. The shaking passes through the air to your ear.
- No vibration, no sound. Stop a drum skin and the sound stops.
- Sound needs something to travel through — air, water or solid.
- Space is empty, so sound cannot travel there at all.
- Bigger vibrations make louder sounds.
- Faster vibrations make higher sounds.
- Sound travels faster through water and solids than through air.

- Who is the How Sound Works poster for?
- How Sound Works is filed under 2nd Grade (ages 7–8), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting science, and to the parent or teacher answering the question at the kitchen table.
- When should you use the How Sound Works poster?
- Put a hand on your throat and hum. That shake is the sound being made. A wall chart earns its place by being glanceable from where the work is happening, so How Sound Works belongs on the wall where that science work actually happens, within glancing distance, rather than filed away.
- What other posters go with How Sound Works?
- Food Chains, Habitats and Life Cycle of a Chicken sit alongside How Sound Works in the 2nd Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Food ChainsHabitatsLife Cycle of a Chicken
- Is the How Sound Works poster free to download and print?
- Yes. How Sound Works downloads as a free PDF with no account, no email and no watermark, like everything else in the 2nd Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the How Sound Works poster print at?
- How Sound Works is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of How Sound Works loses nothing.Printing guide
