1 – 13 of 13 Classroom Resources

  • Elements, Atomic Spectra, Identifying an Unknown, Emission Spectrum, Electromagnetic Spectrum, Emission Spectrum | Middle School, Elementary School

    Lesson Plan: Elements Are Out of This World

    In this lesson, students will learn about the elements that make up Earth’s atmosphere and lithosphere and then compare and contrast the information with the elements that compose various other astronomical objects.

  • Physical Properties, History, Periodic Table, Model of the Atom, Atomic Theory, Atomic Mass, Subatomic Particles, Chemical Properties, Atomic Number | High School, Middle School, Elementary School

    Activity: Mendeleev Video Questions

    In this activity, students will watch a video and answer questions about Dimitri Mendeleev. They will learn about his contribution to chemistry, including his organization of the periodic table and awareness to leave gaps for elements that weren’t yet discovered.

  • Physical Properties, History, Periodic Table, Atomic Mass, Subatomic Particles, Chemical Properties | High School, Middle School, Elementary School

    Activity: History of the Periodic Table Video Questions

    In this activity, students will answer questions while watching a video about how the periodic table was developed and learn about those who contributed to it.

  • Elements, Periodic Table, Model of the Atom, Subatomic Particles | Middle School, Elementary School

    Activity: Element Brochure

    In this activity, students will research a common element from the periodic table and create a brochure about it. Students will include information about its atomic structure, subatomic particles, Bohr model, chemical symbol, and common uses.

  • Periodic Table, Atoms, Matter | Elementary School

    Lesson Plan: The Periodic Table of Elements

    In this lesson students will be introduced to the Periodic Table of Elements. Students will learn that matter is made of small particles called atoms, too small to see with the naked eye. They will also learn that there are more than 100 different types of atoms, which are presented on the Periodic Table of Elements.

  • Electricity, Electrons | Elementary School

    Lab: Making the Connection

    In this lab, students will learn about closed and open circuits. Students will use holiday lights, a battery, and foil to make a closed circuit.

  • History, Model of the Atom, Atomic Theory, Subatomic Particles, Electrons | High School, Middle School, Elementary School

    Video: Niels Bohr Video

    This video tells the story of Niels Bohr, a great scientist who redefined how we think about atoms and the electron. Bohr’s model of the atom helped to advance understanding of subatomic particles, and holds an important place in the history and development of the atomic theory.

  • Periodic Table, Model of the Atom, Subatomic Particles, Atomic Radius, Ionic Radius, Electrons | High School, Middle School, Elementary School

    Animation: Atomic & Ionic Radii Animation

    In this animation, students will have an opportunity to visualize atomic and ionic radii. They will look at the different sizes of atoms in the third period and the atoms in the sixth group. They will also look at an atom and its cation as well as an atom and its anion.

  • History, Periodic Table, Model of the Atom, Atomic Theory, Atomic Mass, Subatomic Particles | High School, Middle School, Elementary School

    Video: Dimitri Mendeleev Video

    This video tells the story of how Dimitri Mendeleev organized the periodic table, even leaving gaps to be filled in with elements that weren't yet discovered.

  • Atomic Mass, Subatomic Particles | High School, Middle School, Elementary School

    Video: History of the Periodic Table Video

    In this video, Sam Kean tells the story of the development of the periodic table. He also pays tribute to each of the major scientific contributors, including Dimitri Mendeleev, who made great discoveries through their efforts to best organize the elements.

  • Observations, Physical Properties, History, Model of the Atom | High School, Middle School, Elementary School

    Video: Ancient Chemistry Video

    This video traces the history of chemistry from the discovery of fire, through the various metal ages, and finally to the great philosophers.

  • Electricity, Interdisciplinary, Atoms, Culminating Project, Electrons, Electrons | Middle School, Elementary School

    Activity: Electrical Circuit Quiz Box

    In this activity, students will learn that the flow of electrons within a closed circuit make our lives easier. Students will construct a circuit quiz box that lights up when the correct question and answer are chosen.

  • Naming Compounds, Elements, Interdisciplinary, Atoms, Molecular Structure, Matter, Chemical Bond | Elementary School

    Lesson Plan: Modeling Molecules

    In this lesson, students explore the structure of matter by designing, building, comparing, and evaluating models of a variety of simple molecules.
