Curated OER
WATER CHEMISTRY
Students list reasons why water is important and investigate and graph the freezing points of different solutions.
Curated OER
Reading Labels For Fat Types
Students analyze a variety of cooking oils to determine the amount and types of fats included in each.
Curated OER
Physical and Chemical Changes
Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.
Curated OER
Quantum Mechanics and Atomic Physics
Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.
Curated OER
Quantum Physics
Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...
