  Percent Composition, Measurements, Chemistry Basics, Observations | High School

  Lab: Dehydration of Hydrated Salt Mark as Favorite (6 Favorites)

  In this lab, students are introduced to chemical measurement in a hands-on investigation using a heat source and a hydrated compound. Students will determine the percentage water lost, by mass, from a hydrated compound during the heating process. Additionally, students will analyze and interpret their results in a claim, evidence, reasoning format.

• 

  Concentration, Percent Composition | Middle School, High School

  Lab: Homemade Hydrometers Mark as Favorite (5 Favorites)

  In this lesson, students will engineer simple hydrometers from straws and clay to learn about standard solutions, calibration, and instrument drift. They will use their hydrometers to test the salinity of samples of natural water.

• 

  Percent Composition, Ideal Gas | High School

  Lesson Plan: Investigating Popcorn with the Ideal Gas Law Mark as Favorite (30 Favorites)

  In this lab, students will collect data to determine the pressure inside a popcorn kernel when it pops using the Ideal Gas Law. They will also calculate the percentage of water present in the average popcorn kernel. This resource includes two versions of the student activity, traditional and inquiry.

• 

  Percent Composition, Molecular Formula, Percent Composition, Mole Concept | High School

  Activity: Mystery Gang Empirical Formulae Mark as Favorite (182 Favorites)

  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.

• 

  Periodic Table, Elements, Percent Composition | Middle School

  Activity: The Universe of Elements Mark as Favorite (14 Favorites)

  In this activity, students are introduced to the periodic table and its elements. Student will discuss that all material in the Universe is composed of elements and that the atom is the smallest particle that still has the physical and chemical properties of any given element. Students will engage in an activity to determine the percent composition of common elements in the universe, and based on their results they will hypothesize the identity of each element based on its relative abundance.

• 

  Measurements, Dimensional Analysis, SI Units, Percent Composition, Scientific Notation, Significant Figures, Accuracy, Density | High School

  Lesson Plan: Chemical Measurement Unit Plan Mark as Favorite (112 Favorites)

  The AACT High School Classroom Resource library has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan for introducing concepts student need to collect and use chemical measurements: Percent Composition, Metric Units, Accuracy and Precision, Percent Error, Density, Scientific Notation, Significant Figures, and Unit Conversion. This unit is designed to be used at beginning of the school year and modified based on student math abilities.
