The Water Cycle and Global Warming
Learners study the flow of water in the environment. In this water cycle lesson students evaluate the consequences of changes in the water cycle using data.
Curated OER
Activity One -- Fundamentally Speaking
In this science learning exercise, students examine how the universe is bound with the atomic particles and focus upon the findings of two historical scientists.
Curated OER
Causal Patterns in Density Phenomena
Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.
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
Code Makers - Electron Configuration, Aufbau Principle
Learners write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.
Curated OER
Drops on a Penny
Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.
