But what does that mean? The simple answer is how heavy something is for its size. If something seems very heavy for its size (like a heavy metal object), we say it is more dense. If something seems ...

Scroll down for a quick way to measure snow density using a measuring cup, then get out there and start scooping! Density is a measure of the mass per unit volume of a substance. Think of it as the ...

MIT researchers found a way to measure cell density quickly and accurately -- measuring up to 30,000 cells in a single hour. They also showed density changes could be used to make useful predictions, ...

Puny particles have given scientists a glimpse inside the Earth. For the first time, physicists have measured the planet’s mass using neutrinos, minuscule subatomic particles that can pass straight ...

👉 Watch the video of Sarah’s school science experiment at Forester Elementary here! Hello parents, teachers and students! If you’re looking for a fun way to explore the physical properties of density ...

Black holes are some of the most intriguing objects in the universe. They have tremendous mass and density, so nothing can escape once it has fallen in, not even light. But how do black holes form? In ...

Researchers at the Max Planck Institute for Solid State Research have discovered charge density waves in ceramic yttrium and neodymium barium cuprates. They form above the temperature at which the ...
