Solve problems concerning real-world situations using your knowledge of volume, surface area, and density. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Density is the ratio of mass to volume. Density will be introduced to students by a demonstration of coke verses diet coke. The teacher will then solve density problems for the students on the board. The class will then complete a lab on...

Cumulative relative frequency graph problem.

Practice your density, mass, and volume calculations with these interactive review problems.

On many occasions, physicists, other scientists, and engineers need to make approximations or "guesstimates" for a particular quantity. What is the distance to a certain destination? What is the approximate density of a given item? About...
