Sudsy Cells
Let's hope that your soap is doing what it's supposed to! The second of six installments in the Cells unit has scholars perform an experiment cultivating bacteria in Petri dishes. They test soaps and detergents to see which is most...
Curated OER
Break the Tension
Students experiment with the concepts of surface tension. They participate in a number of different experiments that introduce them to surface tension. They work in a small group in order to conduct these experiments.

Magnetic Fluids
Teams work as material engineers to create ferrofluids, whose shape is influenced by magnetic fields. The activity, which is the fourth in the six-part series, has the teams create magnetic ink and use it to write, testing it with a...

Surface Tension Basics
Back to the basics (of surface tension). The first installment of a nine-part series teaches young scholars about the basics of surface tension and how it relates to water droplets. They also learn how this concept allows for the...
National Nanotechnology Infrastructure Network
Synthesis and Characterization of CdSe Quantum Dots
Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should notice a...
Curated OER
Describe Environmental Interrelationships
Students describe environmental interrelationships using list of criteria. They are able to explain organism interaction, based on definitions provided. Also, students can use references and worksheets, to describe effects of pollution...
Curated OER
Emulsions
Students identify the characteristics and composition of emulsions. For this chemistry lesson, students classify household products according to emulsion type. They explain how to make the best emulsion.
Curated OER
Indicator Sponge A Discrepant Event Demonstration
Students explore the use of acid and base pH indicators. The teacher saturates an indicator sponge with congo red solution. Afterwards, the sponge is placed in a blue base solution. Students observe that the blue sponge actually turns...
Curated OER
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.
Curated OER
Activity #8 Simulation of Oil Spills
Students conduct an experiment to simulate an oil spill and identify the characteristics of oil in water. They evaluate the effectiveness of various cleanup methods. They discuss the how to clean up an oil spill, and what causes oil...
Curated OER
States of Matter and Gas Laws
In this matter worksheet, students review the states of matter and the gas law formulas and equations. Students then complete 7 multiple choice questions and 6 problems.
Curated OER
Water Unit
Students make boats and race them. For this physics lesson, students investigate surface tension, molecules, and cohesion by competing in a class race with their boats. Students experiment with liquid soap to see how much will make their...
Curated OER
Emulsion_ Compulsion
Middle schoolers experiment with common household products to determine the properties of emulsions and how they fit into the classifications of matter through this series of lessons.
