An Intuitive Introduction to Density

Keep your hands on the wheel—at all times! Scholars learn why pilots use a flight computer through a high-flying demonstration. Making calculations for speed, distance, or time is automatic if you know how to use a flight computer. 

Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities: Measurement of the mass and volume of fruit in order to compare densities Measurement of the mass of oil and...

Written as a textbook reading guide, this worksheet covers foundational concepts for any general chemistry class. From scientific method, measurement, and temperature, to more chemistry-specific topics like chemical and physical changes,...

Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...

This sequence of slides is a fabulous introduction to the concept of density as it relates to mass, volume, physical impact, and interpretation. Various examples are given and your class will find the charts and procedures helpful in...

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

The focus of this chemistry video is kinetics, which is a study of exactly what happens to compounds when they react together. Specifically, kinetics is a study of the rate of chemical reactions, and what forces affect that rate. Sal...

I would open with a joke, but it's no laughing matter. Introduce your young scientists to the concepts of matter, mass, weight, volume, and density with a presentation that includes definitions, simple formulas, and things to remember. 

Seventh graders discover the definition of density through a demonstration using ethanol and ice cubes and a class discussion using a SMART Board to illustrate formulas and calculations. Students finish the instructional activity by...

Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third lesson in a seven-part series challenges scholars to find the mass and volume of two unknown liquids. Each...
