Activity: A Stoichiometry Puzzle
In this activity, students will develop a better understanding of how to set up a stoichiometry problem using dimensional analysis (factor label method). Students will be able to use their prior knowledge of mole conversions and chemical reactions.
-
Percent Composition, Molecular Formula, Percent Composition, Mole Concept | High School
Activity: Mystery Gang Empirical Formulae
In this activity, students will determine empirical formulas for samples of trace evidence collected from various crime scene scenarios. They will use the information to link a criminal to a particular crime scene.
-
Percent Composition, Mole Concept, Identifying an Unknown, Emission Spectrum | High School
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.
