Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

High schoolers are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory

Prepare your chemistry charges for stoichiometry with this PowerPoint. The objective is to be able to calculate molar mass for different compounds. Beginning with the foundational definition of moles and moving through atomic and...

In this atomic structure worksheet, learners explain that an atom is made up of protons, neutrons and electrons. Then they explain that the atomic number is equal to the number of protons and the mass number is equal to the number of...

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

For this atoms activity, high schoolers compare sub-atomic particles' position, relative charge, and relative mass. High schoolers define mass numbers and atomic numbers. This activity has two graphic organizers and four short answer...

Up and atom! After labeling the parts of an atom, young chemists answer 16 diagram-based questions that deal with protons, neutrons, electrons, and atomic number.

Bring a historic chemistry experiment to life in your classroom! Introduce pupils to Thompson's ground-breaking discovery of the electron through a cathode ray simulation. The resource allows users to study the behavior of both electrons...

Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this...

For this elements worksheet, students determine the atomic number, mass, number, electrons, protons, and neutrons for elements. Students review the electromagnetic spectrum. This worksheet has 1 graphic organizer and 13 multiple choice...

In this chemistry learning exercise, students read about atoms, their charges, and their parts; protons and neutrons. They examine how to determine atomic weight by looking at an example. They work online as they practice finding the...

Students study the significance of the quantum model and how scientific theories adapt over time.  In this investigative lesson students describe the contributions that scientists have helped develop the atomic theory and identify...

At the end of a general physics course focused on light and electricity, you can administer this exam. Concepts covered include electromagnetism, circuits, induction, light rays, lenses and mirrors, characteristics of light, electron...

In this atoms worksheet, students circle the term in parentheses that makes the 20 statements correct. The statements review the parts of an atom, isotopes, and basic matter principles.

Seven practice problems are presented to physics pros in this assignment. Given the wavelengths, they perform computations for emission spectra. This brief worksheet makes an appropriate pop quiz.

In this chemistry review worksheet, students read about atoms and the periodic table and they complete a chart using the periodic table to find the atomic number, atomic mass and group of given elements. Students answer 5 questions about...

Students are introduced to the elements on the Periodic Table and what is meant by element. Using the Table, they identify the name, atomic mass, number and symbol of each element. To end the lesson, they discover the characteristics...

Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...

In this periodic trends worksheet, students solve ten problems related to elements in the periodic table. Students write electron configurations for atoms and they compare elements and their periodic trends.
