Density and Density Columns Worksheets

Description

This three page student worksheet teaches and reviews the concept of density using concepts drawn from Indiana Jones and density columns.

The worksheet gives practical and useful ideas for how to determine the density of household items.

Students cut out and layer the liquids they find based on molecular weight (given table) into the worksheet’s density column.

Making Density Columns

The students then use household items to create their own density column, making guesses as to the viscosity and density of the liquids they find.

Recording their data in the provided worksheet, students then find solid objects of varying weights and densities to see a practical application of solid and liquid densities.

Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.

Density also explains why things float. A cubic inch of wood weighs less than a cubic inch of water, so the wood will float. The wood is less dense than the water. A cubic inch of lead weighs more than a cubic inch of water, so the lead will sink. Lead is more dense than water.

Density columns are made by layering liquids of different densities. If neighboring layers are insoluble with each other, the column will stay in separate layers unless disturbed.
