Changing the Density of a Liquid - Adding Salt
Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...
Santa Monica College
The Density of Liquids and Solids
There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...
Curated OER
Solids, Liquids, and Gases
Students explore the three main forms of matter: solid, liquid, and gas. They examine concrete examples of each, using their five senses and "experimenting" to find differences in them. They find pictures of each, cut them out and past...

Liquids Have Differnt Viscosities
Students explore visosity of matter. They run tests of various liquid substances to observe and compare rates of flow of different substances. In addition, they relate viscosity to distance travelled by sample substances.

Thermal Energy Flow in Materials
The sun sends the earth 35,000 times the amount of energy required by all of us on the entire planet, every day. The fourth instructional activity in the 10-part series looks at how light energy from the sun transfers into thermal...

Red, Green, and Blue Mystery Liquids! Hypothesis or Inference?
Eighth graders are actively involved in the scientific method and inquiry as they form quick hypotheses based upon a teacher set of mystery liquids. They determine the need to make additional observations of the liquids.

Solubility of Gases in Liquids
Students observe demonstrations to show the solubility of gases in liquids. In this gases lesson, students discover the relationship between temperature and pressure to and how they affect the solubility of gases in liquids. Students...

Plate Tectonic - Volcanoes
Students watch and learn the different levels of "viscosity" in liquids to explain molten lava after viewing a video of a Hawaiian volcano.
Curated OER
Volcano Under the City
Students examine the different flow rates of liquids and how lava's viscosity influences flow. In this liquids lesson students complete several handouts and a lab activity.

Viscosity: The Fluid Lab
There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...

Acrylic "Shingles"
Young artists of all ages create texture using dried slabs of pourable acrylic paint. They experiment with texture by turning a liquid into a solid and finally into a 3-D work of art. This lesson uses easy-to-find materials, and the...

Understanding Viscosity through Investigation and Comparison of Fluids
Not all liquids are the same. Investigate the viscosity of different fluids with a series of activities designed for eighth grade science. As learners move through learning centers with different experiment setups, they determine the...

Happy Landings: A Splash or a Splat?
Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. For this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...
101 Questions
You Pour, I Choose
Tall and skinny or short and stout, which glass hold the most liquid? Learners analyze dimensions of cylindrical glasses to determine the one holding the greatest amount of liquid. They brainstorm the relevant dimensions before making...

Earthquakes
Students observe the melting of ice. In this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.

Through Thick or Thin!!!
Young scholars differentiate between high and low viscosity. Students collect, graph, and interpret data, then quantitatively measure polymer solids. Young scholars experiment with a household example of an emulsion polymer.

Molecular Forces at Work: Creating Soap Bubbles
Students investigate adhesion, cohesion and surface tension. For this molecular forces lesson plan, students observe multiple demonstrations that show surface tension, the attraction of water molecules to each other and the ability of...

It Matters
Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

What is Sound? How Can We Change Sound?
In this lesson, students investigate the phenomenon of sound! Students compare and contrast how sound travels through solids, liquids, and gases. They explain how length and thickness affect sound. Students know the difference between...

Make Your Own Quick Sand
Students create a quick sand model using cornflour and water. In this earth science activity, students explain why stirring the mixture quickly makes it thick but the opposite happens when you stir it slowly.
