In this Bohr model instructional activity, students draw Bohr energy level diagrams for 14 ions. They draw the electrons in the outer orbitals and indicate the charges on the ions.

In this Bohr model worksheet, students read about Neils Bohr and the model he proposed of the atom. Students answer nine questions about his theory that electrons travel in orbitals and give off energy when they are excited.

In this Lewis structures worksheet, learners draw 12 Lewis dot structures for 8 compounds and 4 polyatomic ions using electrons in the outer orbitals to show bonding.

In this modern atom worksheet, students answer 7 questions about electron configurations of atoms, flame tests, spectroscopy, the energy of electrons and quantum numbers. Students write electron configurations and orbital filling diagrams.

In this plasmasphere worksheet, students read about the dilute region of gases 10,000 kilometers above the Earth where atoms are ionized. Students use a photograph taken by the IMAGE EUV instrument to answer 3 questions about the...

In this atom worksheet, students answer 31 multiple choice questions about the structure of atoms, the periodic table, the reactivity of elements, orbital diagrams and the families of elements.

Students study the seasons of the Earth. In this seasons instructional activity, students study the science of the seasons on Earth by studying the tilt and axis of the Earth's orbit. Students read background information and four...

Demonstrate the lunar cycle to youngsters using flashlights and lollipops. The procedure is somewhat vague, so it will need to be modeled for them before turning them loose to try it. The questions that follow the activity are not...

High schoolers investigate the concept of common errors that are made in the laboratory setting while analyzing the data of an experiment. They are given a scenario and are asked to measure the data of the major and minor axis. The...

Students explore the planet Earth, outer space, and Earth's axis. They demonstrate reading comprehension skills, including literal meaning, inference and critical analysis.

Students explore the characters and plot of the story, "Charlotte's Web" through the twenty-two lessons of this unit. Characters, facts, and details of the story are recalled and discussed and form the basis of several activities in this...

In groups, students create their own scientific impact experiments using ordinary materials, and observe and measure results with a variety of impacting bodies and velocities.

For this moon worksheet, students will fill in the blank of 6 statements relating to how the moon rotates around the Earth including the phases of the moon.

In this sun worksheet, students brainstorm the different ways the sun affects the Earth. This worksheet is a graphic organizer.

High schoolers derive the velocity in a circular orbit of any radius. They derive the Earth escape velocity and prove Kepler's 3rd law for circular orbits # A simple formula for the orbital period in a circular Earth orbit of given radius.

Pupils plot and analyze NASA data to determine the period of an invisible planet orbiting a wobbling star. They explore the motion of a two-body system around a center of mass to better explain how extra-solar planets are discovered.

Students investigate the elliptical orbit around the Sun. They use the information gathered to measure the distance to the Sun from the closest orbital point and the farthest orbital point.

Students investigate how engineers navigate satellites in orbit around the Earth and on their way to other planets in the solar system. They study vocabulary words and participate in studying a satellite by learning about times and...

Students observe and discuss motions of the Earth and the Moon as they spin and orbit the Sun.

Students create a booklet about the inner planets after researching the characteristics of each planet. Students research the following items for each planet: moons, size, rotation, orbit, atmosphere, an interesting fact. Their final...

Eighth graders define a planet by the orbit around the sun, have a large enough gravitational force to hold a sphere shape and needs to clear the neighboorhood of it own orbital zone. They describe comets, meteoroids, meteor, meteorites...

Students will use their bodies to act out the motions of Earth by exploring orbits, rotations, and the turning of the earth as it revolves around the sun. Doing research to find correct answers to their questions will help them act out...

Students explore the orbital characteristics a planetary home needs to support Earth-like life forms. They develop an understanding of critical planetary mass to determine which newly discovered planets might be capable of supporting life.

Learners engage in an overview of solar and lunar calendars, their history and lore. Also, of the day and the month, and their relations to the rotation period of the Earth and the orbital period of the Moon.
