1 – 2 of 2 Classroom Resources

  • Percent Composition, Mole Concept, Identifying an Unknown, Emission Spectrum, Empirical Formula, Percent Composition | High School

    Access is an AACT member benefit. Lesson Plan: Chemical Analysis of Martian Rocks

    In this lesson, students are challenged to analyze the spectral graphs obtained by the Curiosity Mars Rover. Based on their examination students will determine the component elements of each sample, as well as the relative abundance of each element. With this information the student will complete calculations to find the empirical formula and identify the composition of the unknown rock. Finally students will complete research to see if these rocks are actually like those on Earth.

  • Molecular Formula, Empirical Formula, History, Interdisciplinary | High School

    Access is an AACT member benefit. Activity: Herbal Remedies

    In this activity, students learn how the modern atomic theory evolved. They further their understanding of empirical and molecular formulas through research and a presentation of an herbal remedy.
