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...

Investigators use indirect evidence to guess what is occupying a sealed box. You could also use a set of plastic Easter eggs to encase the unknown items. Another terrific activity involves having students drop a pencil on a sheet of...

In this Rutherford model worksheet, students read about Rutherford's experiment with gold foil and alpha particles which led to the discovery of subatomic particles. Students answer six analysis questions about the experiment and...

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...

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...

This discovery student page offers students an opportunity to work as a team to discover the shape of an object they cannot see. It is an experiment which parallels particle physicists dilemma in not being able to see very small...

In this early history of the atom worksheet, students 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.

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...

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

In this history of the atom instructional activity, students answer questions about Thomson's cathode ray apparatus, Rutherford's gold foil experiment and Dalton's beliefs about the atom. Students identify the number of protons, neutrons...

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...

Students investigate what is inside three different boxes using indirect observations and relate it to the discovery of the structure of the atom. In this atomic structure lesson plan, students explore the history of atomic structure by...

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...

Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...

Students investigate atomic and nuclear structure of matter by researching historical atomic theories. Students examine Rutherford's studies and discover that many scientific conclusions change over time as new data is collected.

Students build electrical circuits. In this instructional activity teaching pre-service teachers how to use the 5E instructional model, students use materials to explore how to create an electrical circuit.

In this atom model worksheet, students explore how scientists developed the Bohr-Rutherford atom model. Students complete 15 fill in the blank statements.

In this periodic table activity, students complete a table of elements with their atomic number, atomic mass and symbol. They classify elements by their group name and distinguish between metals, nonmetals, and semi-metals. They also...

Trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them,...

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...

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,...

In this electronics worksheet, students explore the properties of semiconductors to complete 17 short answer and problem solving questions.

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Eighth graders discuss and write about what led up to the discovery of the atom. Students label proton, nucleus, electron, and neutron in their notes. Students take notes on electron shells and how different atoms have different...
