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...
Curated OER
Intrinsic Viscosity
Students treat a high molecular weight polyvinyl alcohol polymer with potassium periodate. They measure the viscosity of polyvinyl alcohols.

Physical Properties of Matter
Five fabulous procedures introduce physics or chemistry classes to special properties of matter. They discover adhesion and cohesion, solubility, melting and boiling points, and viscosity through hands-on experiences. Tests are...
Curated OER
Cross-Linked Polymer Lab
Students use short-chain polymers and borate ions to produce cross-linked polymers in the lab. In this cross-linked polymer lesson plan, students produce polyvinyl acetate slime and polyvinyl alcohol slime and test their physical...
Curated OER
Liquid Logic: Experiments in Viscosity
Students examine specific characteristics of liquids through a hands-on lab activity. An experiment with teacher prepared viscosity tubes is conducted in which liquid identities are predicted based on data. A hypothesis is written to...
Curated OER
Oils and Plastic
Peruse the properties of polymers with your materials engineers, chemistry aces, or emerging ecologists. The inquiries in this resource include puncturing polyethylene plastic bags, dissolving polystyrene cups, creating a polymer ball...
Curated OER
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
Learners examine the different flow rates of liquids and how lava's viscosity influences flow. For this liquids lesson students complete several handouts and a lab activity.
Curated OER
Liquids of Different Densities
Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

Float or Sink?
Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...
Curated OER
Cosmetic Products Evaluation
Students evaluate different cosmetic products. In this chemistry instructional activity, students determine the physical and chemical components of their samples. They perform various test such as pH, viscosity, conductivity and...
Curated OER
Through Thick or Thin!!!
Students differentiate between high and low viscosity. Students collect, graph, and interpret data, then quantitatively measure polymer solids. Students experiment with a household example of an emulsion polymer.

Applying Scientific Method to Analyzing
Students review the scientific method and basic lab skills, and practice how chemical employees work in teams to follow the scientific method. Students learn about various job requirements and responsibilities in the chemical industry.
Curated OER
Laboratory - Density of a Material
Middle schoolers conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.
Curated OER
Settling Rates of Different Size Particles
Students discover how and why the settling rate of particles differs with the size of the particles. Using different soil samples, they calculate the amount of time it takes for a sample to settle in water for up to forty minutes. They...
Curated OER
Investigating the Effect Of Successive Heat and Cool Cycles on a Thermoplastic material.
Students investigate hot melt glue using a hot melt glue gun as an an injection molding simulator and a melt index viscometer. They evaluate the effect of heating and cooling by weighing the glue extruded over a constant time period.
