How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Earth's vast ocean is full of mysteries! Science scholars discover the big-picture properties that influence its characteristics at different latitudes using a lesson from PBS's Weather and Climate series. After completing a background...

Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

Seventh graders discover the definition of density through a demonstration using ethanol and ice cubes and a class discussion using a SMART Board to illustrate formulas and calculations. Students finish the lesson by practicing...

Students compare the pressure of water at different depths and gain an understanding of how increased water might affect animals living in deeper waters. They participate in an experiment to show that depth, not volume, affects water...

Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...

Pupils investigate the biological and chemical characteristics of water to determine where purple loosestrife occurs. They create data sheets to record water quality tests in several locations and work in groups to conduct the water...

To calculate the volume of a stopper by using the method of water displacement., students work with a web animation. They observe the method and then click a button to gather information about the calculations for the stopper dropped in...

Quiz your learners on density, mass, and volume with six equations. Each equation prompts kids to consider an object made of a different material, and to find the desired measurement.

How fast does water cool? First fifth graders will draw a line on a graph that predicts how fast they think water can cool from boiling. Then they plot the actual data on the same graph to see if their estimate was correct.

Students comrehend that water displacement is a simple way to measure the volume of a solid object. They pour water into a graduated cylinder or measuring cup and its volume is read and recorded. Pupils the volume of an object by...

Learners find the density of two substances. In this density lesson plan, students determine the density of water and ethyl alcohol and compare their densities. They enter their data into the computer to produce a class compiled graph....

Students watch the teacher do a demonstration of density with diet and regular soda. Note: try this first, as different types of artificial sweetener have different densities. Students discuss density and volume. They discuss "Relational...

Students explore the properties of water. In this cross curriculum art and physical science lesson, students experiment with a variety of materials to demonstrate the cohesive forces and adhesion of water. Students create a water color...

Young scholars conduct a series of investigations on the unique properties of water. In this general science instructional activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.

A classic investigation on the density of liquids is explained for you in this lesson plan. Te begin, you prepare water samples of different salinities and then add different food coloring to keep them separated and easily identified....

In this biology worksheet, students use the given clues at the bottom of the sheet to solve the crossword puzzle on density. They identify how density in mass is divided. Students also measure the density of water in grams.

Learners define the terms "mass," "volume," and "density." The relationship between these three terms is established. They observe the differences between Regular and Diet Coke. They develop an hypotheses about why a can of Regular Coke...

High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

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...

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...

In this density activity, students complete a science lab experiment to determine the density that an object will float or sink in water. Students fill in a chart with their data, answer 4 short answer questions and write 1 conclusion...

The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...

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...
