Curated OER
MEASURING THE DENSITY OF WATER
Students perform an experiment to measure the density of tap water vs. salt water.
Curated OER
The Great Ocean Conveyor
Students investigate water density. In this water density activity, students conduct an experiment with food coloring, water and salt to see how the salt effects bodies of water.
Curated OER
What's The Matter: A Sinker or Floater?
Students conduct an experiment. In this water lesson, students watch the lesson "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their items. Students discuss their...
Curated OER
Oceanography: Density: Designing a Hydrometer Lab
Students explore water density and design a hydrometer to measure density. This activity is part of Ocean World's home site and excellent resources and links are provided.
Curated OER
The Weight of Water
Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.
Curated OER
Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. In this water lesson plan, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.
Curated OER
Water Density Boundaries
Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...
Curated OER
Water Density and Stability Lab
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.
