If My Configurations are Correct
Students write the electron configuration of elements in the ground state. In this chemistry lesson, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.
Curated OER
Bouncing Balls
Students create a polymer ball in the lab. In this chemistry instructional activity, students identify the different properties of the polymer they created. They explain what type of chemical reaction took place.
Curated OER
An Ad for an Element
Learners prepare an ad for an element, including properties and uses, in an attention getting format such as that used in the advertising business.
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
Waste Not, Want Not
Students consider the types of debris that litters beaches and conduct research on waste management. They then interview professionals in a particular field of waste management and write reports for a booklet about garbage and sewage to...
Curated OER
Explore Your Natural Habitat
Students identify habitats and understand why they are important to our environment. For this environmental lesson students design their own habitat, observe and record data on the impact their habitat has on the environment.
Curated OER
One for the Money
Eighth graders sort items as they are shown one at a time by the teacher. They attempt to identify the one physical trait the teacher is looking for (metal and not metal). After several objects have been shown and placed in groups, the...
Curated OER
Structure of the Atom
Students practice drawing the atomic structure of several different elements. They complete critical thinking questions about atomic structure and compare the atomic mass units for different ions and isotopes of an element.
Curated OER
Bouncing Balls
Students create a polymer to demonstrate its properties and develop an awareness of the wide variety of uses for polymers.
