Sophia: Definition of Density: Lesson 1
This lesson will define density as mass/volume and provide relevant real world examples of objects with varying densities. It is 1 of 3 in the series titled "Definition of Density."
Sophia Learning
Sophia: Weight
In this lesson, students are introduced to the concept of weight as the heaviness, or mass and density, of an object. This is the first in a series of lessons about weight. Student watch a video tutorial and then can take an online quiz.
Sophia Learning
Sophia: Weight and Size
In this lesson, students see that an object with a larger size does not necessarily have a larger weight than an object which is smaller in size. This lesson will help students understand the relationship between weight and density....
Tyler DeWitt, PhD
Science With Tyler De Witt: Advanced Density Problem 1
Learn how to solve for density when you need to calculate the volume of a cube. [2:49]
Tyler DeWitt, PhD
Science With Tyler De Witt: Density Practice Problems
Learn how to use the density number like a conversion factor, to solve for mass or volume. Watch this video after the density introduction or before the more complicated video on density exercises that has unit conversion. [8:55]
