Concentrating Charge and Electric Fields
How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...
PHET
Band Structure
Electricity travels at the speed of light, 186,000 miles per second. Through a simulation, classes see how the structure of energy bands in crystals of atoms determines how materials conduct electricity. Participants can change the...
Curated OER
Matter
Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.
Curated OER
Chemistry - Science 10
In this chemistry science worksheet, students identify the parts of a chemical reactions. Students name the major particles of the atom. Students apply knowledge about the atom, theories, and models.
Curated OER
Biochemistry Assignment
In this biochemistry worksheet, students complete a table by filling in the missing information about different elements. Students draw the Bohr diagram and the Lewis dot diagram for several atoms.
Curated OER
How do protons stick together in a nucleus?
Students explain that the Standard Model of the atom includes particles beyond protons, neutrons, and electrons. They describe the nucleus as conglomeration of quarks that manifest themselves as protons and neutrons.
Curated OER
Activity #5 Environmental Effects
Young scholars explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are...
Curated OER
The Nature of Matter
Students compare and contrast how the theory of atomic structure has changed over time. They explore how different people have contributed to our knowledge of the atom and its structure. Students identify how matter is made of discrete...
Curated OER
The Story of the Atom
In this atom worksheet, students read about the model of the atom developed by Neils Bohr. Students complete 2 short answer questions based on what they read.
Curated OER
Early History of the Atom Homework
In this early history of the atom worksheet, high schoolers answer 4 questions about Thomson's Plum Pudding model of the atom and Rutherford's experiment that led to the understanding of some of the structures of the atom.
Curated OER
The Average Atom - Isotopes
Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.
Curated OER
Molecular Models Laboratory
Students use models to visualize molecular structures. Students read about Lewis dot structures, hybridization, and formal charge. Then students build and draw the molecules and ions given. Students complete 11 pre-lab questions and 4...
Curated OER
Molecular Modeling Activity
Learners work together to explain the VSEPR theory and how it relates to molecules. They name electron pairs that can surround the central atom of an organism. They discuss the factors that determine the polarity of a molecule as well.
Curated OER
Atoms
For this atoms worksheet, high schoolers circle the term in parentheses that makes the 20 statements correct. The statements review the parts of an atom, isotopes, and basic matter principles.
Curated OER
Chemistry - Atoms and Elements
Students perform varied activities as part of a layered curriculum unit: They write and perform a skit that outlines the evolution of the model of the atom. The script is submitted to the teacher for review before performance.
