  Video: Ingenious Video 5: Making Shipping Greener with Hairy Ships

  The “fouling” of boats — when aquatic animals like barnacles and tubeworms attach to hulls — has been a nuisance for as long as we’ve been sailing the seas. Fouling messes up a vessel’s streamlined shape, decreasing its speed, maneuverability, and in modern times, its fuel-efficiency. Fouling spikes the carbon footprint of the shipping industry, already greater than that of most countries. For centuries, people used copper coatings to prevent fouling. Modern solutions use toxic chemical paints that pollute the water, kill marine life, and contribute to the degradation of our oceans when they wear off. A new approach is trying to work with nature instead of against it. Taking inspiration from the Salvinia plant, which is covered in tiny hair-like structures that make it basically waterproof, scientists are developing a stick-on silicone coating for ships that prevents animal hitchhikers from getting a foothold.

  Video: Ingenious Video 1: The Strange Chemistry Behind Why You Get Sick on Planes

  The compound ozone, a known respiratory irritant, exists in high concentrations at flight altitudes, making the “fresh air” sucked in by air conditioners at those heights, well, not so fresh. In fact ozone exposure may be responsible for many of the short-term discomforts we associate with air travel. What’s more, ozone can react with other compounds in the air -- even the oils of our skin -- to produce other toxic compounds, like aldehydes and ketones. Some planes have catalytic converters, like the ones in cars, which use transition metals to turn ozone into breathable oxygen. But not every plane has one!

  Activity Series, Chemical Change, Electrons, Electron Transfer, Balancing Equations, Chemical Change, Predicting Products, Observations, Acid Base Reactions | High School

  Simulation: Metals In Aqueous Solutions

  In this activity, students will run simulated tests of various metals in aqueous solutions to determine the relative reactivity of these metals. A total of eight metals will be observed in various combinations with the corresponding metal nitrate solutions and hydrochloric acid. Students will interpret the data collected to construct an activity series of the elements used in this simulation.

  Classification of Reactions, Chemical Change, Balancing Equations, Acid Base Reactions, Combustion | Middle School, High School

  Animation: Classifying Chemical Reactions Animation

  This animation explores some of the ways to classify different types of chemical reactions. It covers synthesis (combination), decomposition, single replacement (single displacement), double replacement (double displacement), combustion, and acid-base neutralization reactions. This animation was featured in the November 2020 issue of Chemistry Solutions. **This video has no audio**

  Introduction, Interdisciplinary, History, Heat, Renewable Energy, Polymers, Molecular Structure | Middle School, High School

  Video: Frontiers of Chemistry

  This video explores new scientific developments that were made possible by the application of fundamental chemistry concepts. Students will learn about exciting advances in science and technology focused on three main topics: Solar Cells, 3D Printing and Micro Machines.

  Classification of Reactions, Balancing Equations, Solubility Rules, Activity Series | High School

  Simulation: Predicting Products

  In this simulation, students will reference an activity series and a solubility chart to accurately predict the products of single replacement and double replacement chemical reactions. Associated particle diagrams will be displayed to help students better comprehend the reaction at the particulate level. Students will also be asked to balance the chemical equation. The simulation is designed as a five question quiz for students to use multiple times.

  Reaction Rate, Reaction Rate | Middle School, High School

  Simulation: Reaction Rates

  In the May 2018 simulation, students investigate several factors that can affect the initial rate of a chemical reaction, including concentration, temperature, surface area of the reactants, and addition of a catalyst.

  Stoichiometry, Balancing Equations, Classification of Reactions | High School

  Simulation: Chemical Reactions and Stoichiometry

  In this simulation, students practice classifying different chemical reactions, balancing equations, and solving stoichiometry problems.

  Heat of Combustion, Heat, Exothermic & Endothermic, Combustion | Elementary School, Middle School, High School

  Video: The Internal Combustion Engine Video

  This video investigates both the mechanical and the chemical processes used in the internal combustion engine, as well as the history and evolution of the combustion engine.

  Balancing Equations, Precipitate, Solubility Rules | High School

  Animation: Net Ionic Equations Animation

  This animation explores what happens in a precipitate reaction on the particulate level. Students will see why writing a net ionic equation accurately represents what happens in these scenarios. An example of diluting a soluble solid, mixing two aqueous reactants that yield aqueous products, and mixing two aqueous reactants that yield a precipitate are part of this animation. **This video has no audio**

  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**

  Reduction, Oxidation, Redox Reaction, Catalysts, Activation Energy, Combustion | Elementary School, Middle School, High School

  Video: Catalytic Converters Video

  This video investigates the role of a catalytic converter and its corresponding chemical reactions within a vehicle. Students will learn about both oxidation and reduction reactions and how they, in combination with a catalyst, can impact the molecules released in a car’s exhaust.

  Simulation: Energy Changes in Chemical Reactions

  In the November 2016 simulation, students will evaluate the energy changes in an endothermic and an exothermic chemical reaction. Students will have the opportunity to compare how energy is absorbed and released in each reaction, and will make a connection between the standard energy diagrams associated with each reaction type.

  Balancing Equations, Conservation of Mass | Middle School, High School

  Simulation: Balancing Chemical Equations

  The simulation for the September 2014 issue comes from PhET and helps students practice balancing chemical equations. AACT helped fund the conversion of this popular simulation into a format that is compatible with all devices, including iPads. PhET provides teacher’s guides for many of their simulations, and teacher-generated activities that can accompany the simulations.
