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...

Atomic bombs harness the power in the nucleus of an atom, creating devastating power and damage. Classes review parts of an atom by charging a piece of plastic and holding it near their fingers, discussing what is happening and why....

For this elements worksheet, students review the Bohr model and define negative and positive subatomic particles. Students compare molecules and compounds. This worksheet has 11 short answer questions and 4 problems to solve.

Young scholars 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.

Historically, scientists had to be creative to study subatomic structure. Scholars step into their minds to recreate the procedure Rutherford used to create his atomic model. Learners identify the creative efforts of early scientists...

In this science worksheet, students choose the multiple choice science term that best matches the 15 definitions stated. Students circle their answers.

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

In this matter activity, students will read 11 clues on the topic of the different types of matter and put the answers into a crossword puzzle.

Students conduct a simulation to determine radioactive decay and half-life. Using pennies, dice or sugar cubes as isotopes placed in shoe boxes simulating rocks, they hold five trials representing 1000 years each to find the theoretical...

Eighth graders experiment with a Geiger counter and a dosimeter to test the amount of radiation in a room and the amount of radiation received in a day. In this radiation energy lesson plan, 8th graders test the shielding effect of...

Students describe the science of physics. In this Physics lesson, students observe examples of physics within their classroom. Students create a definition for physics.

In this chemistry review worksheet, students answer and solve 95 questions about chemical reactions, hydrocarbons, functional groups, moles, acids and bases and solutions.

The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...

It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...

Students study atoms and their protons and neutrons.  In this physical setting instructional activity students work together to complete a lab activity. 

Young scholars create an atomic model using a computer program. For this technology lesson, students identify the difference between radius and diameter. They create circular patterns and spheres based on certain specifications.
