    Density Laboratory

    With a scale to measure mass, a graduated cylinder to measure volume, and a large beaker of liquid to observe flotation, the relationship between mass, volume, density, and flotation can be investigated. The density of the liquid in the beaker can be adjusted, and a variety of objects can be studied during the investigation.

    Archimedes' Principle

    Place weights into a boat and see how far the boat sinks into a tank of liquid. The depth of the boat can be measured, as well as the amount of liquid displaced. The dimensions of the boat and the density of the liquid can be adjusted. See how much weight the boat can hold before it sinks to the bottom!

    Determining Density via Water Displacement

    Drop objects in a beaker that is filled with water, and measure the water that flows over the edge. Using Archimedes' principle, determine the density of objects based on the amount of displaced water.

    Density via Comparison

    Using four beakers of different liquids with a known density, try to determine the density of a variety of unknown objects. Compare the buoyancy of each object in each beaker to determine an approximate value of density without knowing the mass or volume of the objects.

    Density Experiment: Slice and Dice

    Drop a chunk of material in a beaker of water and observe whether it sinks or floats. Cut the chunk into smaller pieces of any size, and observe what happens as they are dropped in the beaker. The mass and volume of each chunk can be measured to gain a clear understanding of density and buoyancy.

    Boyle's Law and Charles' Law

    Investigate the properties of an ideal gas by performing experiments in which the temperature is held constant (Boyle's Law), and others in which the pressure remains fixed (Charles' Law). The pressure is controlled through the placement of masses on the lid of the container, and temperature is controlled with an adjustable heat source.
