  SI Units, Mole Concept, Measurements, Physical Properties, Density | Middle School, High School

  Animation: Units of Chemistry Animation

  This animation explores the importance of including units to communicate the value of measurements effectively. It presents definitions, units of measurement, and measuring tools for physical properties that are commonly measured or calculated in chemistry class: mass, length, temperature, volume, amount (moles), and density. This animation was featured in the November 2022 issue of Chemistry Solutions. **This video has no audio**

  Measurements, Dimensional Analysis | Middle School, High School

  Animation: Measurement Animation

  This animation explores three forms of measurement, including length, mass, and volume. Various units of measurement will be presented for comparison, and several conversion calculations will be demonstrated using dimensional analysis. This animation was featured in the May 2019 issue of Chemistry Solutions. **This video has no audio**

  Measurements, SI Units, Significant Figures, Accuracy | Middle School, High School

  Simulation: Measuring Volume

  In this simulation, students will participate in a 10 question quiz. The quiz questions are each made of two parts, with the first part requiring the student to analyze an image of a graduated cylinder in order to report an accurate measurement. Students must use the correct number of digits based on the markings presented on the cylinder when reporting the measurement. In the second portion of the question the students will determine the uncertainty value of the graduated cylinder, again by analyzing its markings. The simulation is made up of several different sizes of graduated cylinders, each containing unique markings, so students will be challenged to analyze each individually.

  Limiting Reactant, Conservation of Mass, Stoichiometry, Mole Concept | High School

  Animation: Limiting Reactant Animation

  This animation explores what happens in a limiting reactant problem on the particulate level. Assembling a bike is used as an analogy to introduce the concept of limiting reactant, and then the balanced equation of the combustion of methane is used in four quantitative examples to show what it means for a chemical to be a limiting reactant. The concept of the conservation of mass is also demonstrated by calculating masses from the mole quantities of the reactants and products. **This video has no audio**

  Density, Matter, Physical Properties, Measurements | Elementary School, Middle School, High School

  Animation: Density Animation

  This animation explores density on the particulate level. There are opportunities to make qualitative and quantitative comparisons between substances. **This video has no audio**
