Curated OER
Chemistry Chapters 8 & 9
In this chemistry learning exercise, students explain the difference between a covalent bond and an ionic bond. Then they write the Lewis symbol for the atoms and ions presented, such as carbon and sulfur. Then they predict whether the...
Curated OER
Heat Transfer & Phase Changes
In this heat transfer and phase change worksheet, students experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...
Curated OER
Intro to Biology Chapters 1 & 2 Practice Test
Don't be fooled by the title - this biology quiz could serve as an AP biology or college-level biology quiz. Some of the molecules represented may be difficult to identify without seeing the textbook from which this is based. It could...
Curated OER
Climate & Atmosphere: A Global & Local Perspective
Middle schoolers complete a series of activities in which they study atoms, molecules, and the presence of atmosphere. They study the water cycle and the Greenhouse Effect by investigating and completing handouts.
Curated OER
Planet Structure & Interior
Students compare Jupiter and Earth. In this Earth and space studies lesson, students compare the composition of Earth and Jupiter and analyze how the composition affects the rate at which the planets spin.
