Here is a way for beginning chemists to review the skill of multiplying fractions! A segment of the periodic table of elements is presented at the top of the page, from which learners obtain the atomic number to use in six calcualtions. For example, they need to determine which element has an atomic number equal to 5 and 2/5 larger than that of neon. This is ideal for your 5th or 6th graders!
In this counting atoms in a molecule worksheet, students read about the molecule propanal that was discovered by the giant radio telescope in the Milky Way Galaxy. Students solve 6 problems where they find the number of atoms in the propanal molecule, they find the percent of given atoms in the molecule and they determine the total mass of the propanal molecule.
Students examine the use of scientific models and how the models change over time. They look at the model of an atom and how it evolved. They make current models of atoms of different elements using modeling clay.
Students are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able to: name different elements of the periodic table, make clay models of atoms and molecules, and define proton, neutron, and electron.
Using a chart of student test grades as an example, curious chemists learn how to calculate weighted averages. They apply this knowledge to elements on the periodic table. As practice in calculating average atomic masses, learners evaluate neon and chlorine. This is a clever way to introduce atomic mass that your class will be certain to remember.
Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have constructed. This is an engaging and memorable way to impress atomic structure.
Eighth graders act out the role of atoms by dressing up as the atoms of designated elements. They explain the difference between an atom and an ion and explain the role of valence electrons.
Students describe the structure of atoms, including the particles that make them up. They recognize that key scientists and experiments have contributed to the changes in the Atomic Theory.
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 results to Rutherford's experiment. Students discuss the subatomic particles of the atom and using a handout of the periodic table they construct a model of a magnesium atom using toothpicks and gumdrops.
In this atoms worksheet, students answer four different sets of questions related to atoms (fill in the blank, multiple choice, word puzzle and true and false).
Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain ions, and determine the number of valence electrons for various elements. This is a well-rounded unit test for the very early high school chemistry learner, or even for middle school physical scientists.
In the atom activity, students read a story about the "Atoms Family" and are given descriptions of the structures of atoms through the story. Students interpret the descriptions by drawing the described atom structure, they name of the structure and its "favorite activity". These stories refer to the subatomic particles of the atom. Students read the "Atoms Family Song".
In this atoms worksheet, students complete 58 questions about the atomic radius of atoms, the ionization energy, the valence electrons, metals, non-metals and semi-metals and the families of elements.
In this atomic structure worksheet, students read a story with characters acting as the particles in an atom. They create a trading card for each particle, draw the structure of an atom and sing an atom song.
High schoolers observe 3 models that show Dalton, Thomson and Rutherford's theories of the structure of the atom. In this structure of the atom lesson plan, students observe each model and write a summary of each theory of the atom.
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 identify and describe electron orbits. In this atom lesson, students make and analyze models of atoms, elements, molecules and compounds. Students view a PowerPoint presentation and discuss the vocabulary.
Eighth graders complete several centers in which they design a brochure on an element, create an elemental trading card and complete a timeline of the development of an atom.  For this element lesson students work together in teams to complete these tasks.
There is something magical about atomic weight. Let learners in your class use a graphing calculator to solve systems of equations related to atomic weight. They use matrix equations and inverse operations to create matrices that describe given compounds.
In this chemistry worksheet, students study the Bohr atomic model and calculate the wavelength and frequency of given electromagnetic radiation. They answer 9 problems and short answer questions.
