Chemistry
Students identify elements on the periodic table and how to read it. They create their own chart for alkali metals and alkaline earth metals. They are evaluated based on a rubric.
Curated OER
Physical vs. Chemical Change Lab
Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.
Curated OER
The Big Balancing Act
Students describe chemical changes occurring in hydrothermal circulation systems. They make inferences about the significance of these systems to ocean chemical balance compared to terrestrial runoff.
Curated OER
Mystery of the Eleven Unknown Substances
Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.

Using the Hunter Model and the Holistic Model
Young scholars increase their knowledge of scientific processes in chemistry. They compare and analyze 3 sets of data, they have gathered, for accuracy and precision.
Curated OER
Chemical Element Interview
Pupils interview the chemical elements. They research information about their element, such as: stable isotopes, valence electrons, number of subatomic particles. They create a yearbook page for their element, and a format to present it.
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.
