Changing the Density of a Liquid - Heating and Cooling
During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

How Does Water Cool?
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.

Heat Up and Cool Down
Don't be so dense! Using food coloring, pupils conduct two experiments with the difference in densities of hot and cold water. In the first experiment, learners add dyed hot and cold water into room temperature water and observe how the...

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

Air Density and Temperature
Young scholars investigate the effect of temperature on the density of air by putting an uncovered bottle in a bucket of hot water. Then they place a balloon over the mouth of the bottle. They repeat the procedure using ice water and...

What Is Viscosity?
Students experiment with the visocosity of corn syrup, mineral oil, vegetable oil, water, and honey. They research viscosity before beginning. Pupils draw the conclusion that the marble sinks more slowly in the liquids with greater...

Density Lessons and the Oil Spill
Teachers can use the oil spill cleanup efforts as a springboard to discussions and activities related to density!

What Floats Your Boat?
This open-ended boat building exercise is meant to be part of a three-activity series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load...

Seashore Explorers
There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...

Sink or Swim
Learners explore sinking and floating. In this buoyancy lesson, students conduct an investigation dealing with regular and diet soda. Learners drop various soda cans into water and then discuss why some float and some sink.
Curated OER
Water Layering and Circulation
Young scholars examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.
Curated OER
Density Currents
Students study how fluids of differing densities interact with one another, how densities of fluids can be changed, and how density currents transport and deposit tremendous amounts of sediment in lakes and in the ocean.

Teacher's Guide For: Water Temperature and Salinity Experiment
Young scholars experiment with water density, temperature and salinity. In this water lesson, 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
Young scholars 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...

Ocean Currents
Learners discover the geography of Earth by analyzing water currents. In this oceanography lesson, students create visual references on a map of the globe where and why major ocean currents are moving water. Learners conduct a water...

How Much Water in Snow?
Students determine the volume of water in a given amount of snow. They calculate a ratio for water volume per snow volume.
Curated OER
Atmospheric Processes -- Convection
Students work together to discover how temperature changes can affect the density of water and air. They make predictions on what they believe is going to occur. They answer questions to complete the lesson.
Curated OER
Investigating Convection Currents
Students examine how differences in the temperature and salinity of the water help create ocean currents. They perform an experiment which shows how temperature affects the circulation of ocean water.

Get to know H2O!
Students investigate scientific concepts and inquire about physical states of matter. The transition of water is considered and is easy to facilitate because of its abundance and often observed physical changes.

WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Young scholars explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
