The Relationship Between Salinity and the Density of Water
Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...
NOAA
Come on Down!
What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second lesson of six from NOAA. Lab groups then...
Curated OER
Density Lab
Students use an Excel spreadsheet to calculate the density various liquids. They take pictures of their results.
Curated OER
i-Density Crisis
Eighth graders determine the density using mass and volume. For this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...
Curated OER
Exploring Buoyancy
Young scholars use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will...
Curated OER
Solids, Liquids, and Gases
Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...
Curated OER
Count Marsili & the Mediterranean Current
Students integrate history and science while discovering how salinity affects the density of water. After a lecture/demo, students work in groups to complete a lab activity that demonstrates how salinity affects the density of water.
Curated OER
Density
Students work with a partner to record observations on various materials. Working together, they calculate the mass and volume of each material and then combine them and shake them for a period of time. In their journals, they record...
Curated OER
Discovering Density
Students explore the physical properties of density. In this hands-on lesson, students calculate density and distinguish between intensive and extensive properties.

Testing Density of Various Soap Products
Middle schoolers have the opportunity to observe, measure and analyze the density of aerosol shaving creams and foams generated from shampoo and dishwashing liquids or detergents.
Curated OER
Density and Buoyancy Lesson Plan
Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.
Curated OER
Comparing the Density of Iron
Students use scientific measuring tools to collect and use scientific data. They determine the density of four different objects by using their data to explain why objects have similar/different densities even though they are both made...
Curated OER
Density of a Gas
Eighth graders investigate the mass, volume, and density of a gas by producing it in a chemical reaction. The entire Density of a Gas Lab and L section of the K W L chart be formatively assessed.

How Big is a Molecule?
Students calculate the size of a molecule. For this molecules and their sizes lesson plan, students find the size of an oleic acid molecule by using a measured amount of drops of oleic acid to find the volume of the sample, the thickness...
Curated OER
Density lab
Students relate the concept of density in relation to the rocks that make up the Earth. They determine the density of various rock specimens and answer assessment questions.
Curated OER
Water Density
Students identify and analyze the concept of density using the formula, density equals mass divided by volume. They review the differences in salinity levels of the ocean and note that the changes in density are caused by wind and...
