What Floats Your Boat?
Students are introduced to the concept of buoyancy. The Video used in this activity demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.
Curated OER
Density Derby
Students explore the relationship between mass, volume and density. They use model boats to discover how changing mass and volume affect density. This is a very engaging lesson which provides great demonstrations and hands-on activities.
Curated OER
Density And Volume
Sixth graders explore the concept of density as a relationship of an object's mass to its volume. Densities of a variety of objects are compared and used to identify an unknown object.
Curated OER
Rock Density Lab
Students use a balance and weigh a rock sample. They weigh the rock suspended on a sling in a glass of water. They tabulate the rock's density using the two weights and compare the density of various rocks of similar sizes.
Curated OER
Are You a Trend Setter?
Students are introduced to the periodic table of elements. They devise and perform and experiment in which they determine the density of specific elements. They use their results to predict the density of other elements in the same group.
