Can Small Pollutants Harm Aquatic Organisms?
Nanoparticles have toxic effects on plant and animal life—even though you can't see them. The second instructional activity of a two-part series has young scientists conduct an experiment that exposes plant and animals to nanoparticle...
Curated OER
Tie Dye
Students practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...
Curated OER
Phases of Matter
Students describe the motion of solids, liquids and gases. In this chemistry lesson, students describe how temperature affect motion of the particles. They determine the physical properties of each phase.
Curated OER
Sink or Swim
Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.
Curated OER
Chemical Bonding
Eighth graders identify the three main types of chemical bonds. In this chemistry lesson, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.
Curated OER
Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
