Four diagrams of the atom and their subatomic particles and structures are given here and students should be able to complete the labels need to define the structures shown. The main structures defined are protons, neutrons, electrons,...

Multiple representations of the varying theories of atomic structure. With these pictures and some background of the theories and scientific figures surrounding them, your class will develop a better understanding of scientific history...

Your students should enjoy this slideshow which includes some basic definitions about the atomic structure of atoms. In fact, this presentation would be best-viewed before giving details and diagrams of neutrons, protons and quarks. The...

Delve into the world of quantum mechanics by viewing this PowerPoint. Chemistry novices learn about electron energy and shells, and they practice listing electron configuration for different atoms. Because this presentation provides...

In this science:  atom quiz worksheet, students answer 10 true or false questions, not interactively, then scroll down to check their answers.

For this atoms crossword puzzle, students read 15 questions about atoms and fit the answers into a crossword. This difficult puzzle has no word bank.

Pupils create atoms with clay by using different colors to represent the protons, neutrons and nucleus. In this creative lesson plan students use clay to learn about atoms and see how they apply to the periodic table.

High schoolers investigate the structure of the atom and its composition. For 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...

In this nucleus and radioactivity worksheet, students collect class data and the students represent radioactive atoms decaying. They plot their data and answer two questions about the results. They solve seven problems given the...

In this atomic structure learning exercise, students answer eleven short answer questions about the structure of atoms including the number of protons, neutrons and electrons. Students indicate the differences in isotopes of atoms and...

Students explore scientific theories and the works of scientists.  In this chemistry instructional activity students develop a timeline  that shows how scientists work was built on the ones before them. 

The difference between atomic mass and atomic number can be confusing for some young chemists. Help your class better understand the concepts by allowing them to sketch an atom on paper and then discuss their experience. Upon completion...

Simple in format and standard in content, this resource is an assessment of your beginning chemists' grasp of the atom. Using a periodic table of elements, they fill in a chart of missing chemical formulas, atomic masses, and numbers of...

In this atom worksheet, learners read about the model of the atom developed by Neils Bohr. Students complete 2 short answer questions based on what they read.

In this atom worksheet, students will complete 8 fill in the blank statements based on the different parts of an atom. Then students will explain how the arrangement of electrons in an atom is related to the periodic table.

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.

In this chemistry worksheet, students complete 29 fill in the bank questions about atoms based on the movie Exploring Atoms from the website www.brainpop.com .

In this atoms worksheet, students review atomic number and mass number of atoms plus what happens when an atom is radioactive. This worksheet has 8 fill in the blank and 9 short answer questions.

Learners research and define an atom using a concept map. They design and create a model of an atom, labelling all the parts, and write a journal entry.

Chemsitry aces learn that protons are located in the nucleus and the number of protons in the nucleus determines the atomic number of an element. In this lesson, they compare materials made up of a single element and other materials...

What does the past have to do with today? Young scientists find that answer as they learn more about past chemists and their significant contributions to the field. Pupils use the Internet to research historical figures...

Rutherford performed his famous experiment in 1907 with Marsden, showing the true atomic structure. This interactive simulation compares Rutherford's historical experiment to the Plum pudding model of the atom. In both models, alpha...

What's the likelihood of your class understanding probability maps? Young scientists explore the concept using a virtual dartboard in an interesting simulation. The darts establish a pattern around the bull's-eye, which provides a visual...

In this atoms worksheet, high schoolers review atoms, atomic number, and mass number. Students determine what happens when atoms become radioactive. This worksheet has 8 fill in the blank and 9 short answer questions.
