For 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.

In this creating atoms worksheet, students follow directions by creating atoms out of cotton balls, beads, and pipe cleaners. Students then answer 2 questions.

Students explore what causes differences in density. They observe an models depecting atoms, compounds, and molecules. Students determine if there is air in between atomic bonds. They study the structure and spacing of molecular bonds.

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.

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...

Eighth graders discuss atoms and electrons as well as atoic structure. They view atomic structure via the computer. Students watch a demonstration in which the teacher demonstrates glass tubing turning yellow in a Bunsen Burner flame....

In this atomic fingerprint learning exercise, students read about the Bohr model and electrons changing energy levels and emitting energy. They answer questions about the atomic spectrum and the fingerprints for specific atoms.

Students define vocabulary related to the parts of the atom.  In this matter instructional activity, students navigate the web to find the structure and the forces that affect atoms.  Students complete an experiment with...

Students build metal atomic models using styrofoam. In this chemistry lesson, students identify the different unique properties of metals. They explain how metal atoms bond.

Students analyze and evaluate evidence that matter is made of tiny particles. They observe a series of phenomena involving solids, liquids, and gases to make inferences about the spacing, interactions and relative kinetic energies of the...

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...

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

Mostly what you will find here is a history of quantum mechanics. Influential scientists are introduced (along with some of their recorded quotes), the progression of atomic models is reviewed, and finally experssions and equations are...

Although there are only 16 questions here, this chemistry handout makes a terrific unit assessment. It queries youngsters on the properties of ionic and covalent compounds, relates bond length tho stability and enrgy, compares polar and...

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....

The carbon cycle is natural and has happened for millions of years, so can humans change it? Young scientists play the role of carbon as they travel through the carbon cycle. They complete two rounds, once before the industrial...

The fifth lesson of seven in the series outlines an in-depth analysis of the periodic table. After direct instruction, pupils take turns practicing in the group before beginning independent study. The assessments include a...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Students are introduced to many of the scientists who contributed to the creation of the model of the atom. The changes to and evolution of the model over time is also covered. At the end of the lesson, Students differentiate between...

Ninth graders examine how scientist's contribute to atomic theory.  In this development of a scientific idea lesson plan students work in groups and research the development of the atomic model. 

In these creative hands-on activities, students construct several different molecular models that represent substances that play an essential role in our nutritional needs. Using gum drops and toothpicks, students design the models....

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...
