Concluding a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate densities of several household liquids and compare them to the densities of irregularly shaped objects (as determined in Part 1). Then they create density columns with the three liquids and four solid items to test their calculations and predictions of the different densities. Once their density columns are complete, students determine the effect of adding detergent to the columns. After this activity, present the associated Density & Miscibility lesson for a discussion about why the column layers do not mix.

In this lab activity, students determine density differences of water samples with varying temperature and salinity levels. Students synthesize information to predict the effects of oil in given water samples.

Students will compare and give examples of density-independent and density-dependent factors and how they have an effect on the changing conditions on a lake. After establishing the difference between them, students will play a game where they change several factors and assess the effects of their changes to the environment. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

This lesson will allow students to experiment with different objects to predict and explain the results of their experiments on the objects as they relate to density. Through this experiment, students will be able to understand the cause and effect relationship to explain the objects sinking or floating. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

In this activity, students measure the densities of samples of granite, basalt, peridotite/dunite, and an iron meteorite, which are used as representatives of the various layers of the Earth (crust, mantle, core). The samples are weighed to determine their mass, and the Archimedes Principle is used to determine volume. From these two properties, they calculate density, compare it to accepted values presented in the discussion, and answer questions about their observations.

This module addresses the real problem of determining the density of the Earth and invites the student to figure out how to solve the problem.
