  Animation: Atoms: The Building Blocks of Matter Animation Mark as Favorite (25 Favorites)

  This animation explores the idea that everything is made of atoms, and that since atoms are so extremely small, even small objects contain vast numbers of atoms. Students will see several examples to illustrate this point. Then they will be given a brief overview of the evolution of how people thought about atoms from the ancient Greeks through Dalton. This animation was featured in the May 2022 issue of Chemistry Solutions. **This video has no audio**

  Activity: Chemistry Kakuro Puzzle Mark as Favorite (5 Favorites)

  In this activity, students will use both math and logic to solve a chemistry themed kakuro puzzle. This puzzle differs slightly from a traditional kakuro by first requiring students to use a periodic table to find the atomic number for each element symbol appearing in the puzzle. Using the atomic numbers as starting clues, students then fill-in the empty squares with numbers 1-9 that sum to the value of the clue, but without reusing any digits. This activity is a fun challenge for students, and provides the opportunity to strengthen logic and reasoning skills.

  Lesson Plan: Clean Air Chemistry Mark as Favorite (19 Favorites)

  In this lesson, students will learn about air pollution and some steps toward mitigating it. First, they will burn a candle and measure its mass and the concentration of CO2 over time. Students will discuss which data set they have more confidence in and why and then use stoichiometry to predict outcomes. Next, students explore incomplete combustion in a model-based worksheet that shows how a lack of O2 in the burning of fuels can produce air pollution. Students work together to interpret the models, define terms, and draw conclusions. Lastly, students work in groups using Lego models to illustrate how a catalytic converter works. They race “Nature” against catalysts “Palladium,” “Platinum,” and “Rhodium” to see what breaks down air pollution molecules fastest.

  Activity: Ingenious: Oversexed Moths Are Ruining Apples for Everyone Video Questions Mark as Favorite (4 Favorites)

  In this activity, students will answer questions while watching the video Oversexed Moths are Ruining Apples for Everyone from the Ingenious series produced by the American Chemical Society. Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates how the larvae of codling moths wreak havoc in orchards—burrowing into fruit and eating them from the inside out. Scientists are developing synthetic, species-specific pheromones as an alternative to pesticides. Pheromones are scented chemical messages that animals release at mating time and can help to prevent male codling moths from finding females to mate with. No mating means no eggs, no larvae and no more bad apples!

Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates the global shortage in accessing clean water. Using a technology that was first developed to reuse dirty laundry water, scientists have developed a water treatment plant the size of a teabag that contains a chemical triple-threat—it removes microbes, heavy metals, silt and dirt to produce clean, safe water.

  Video: Ingenious Video 8: Is the Answer to Overfishing… Algae? Mark as Favorite (3 Favorites)

  Omega-3s are an essential nutrient that humans have to get from fish. But many of the world’s wild fish species are in crisis because we’ve taken too many of them from the ocean. So the answer is to farm more of our fish, right? While fish-farming relieves some pressure on the ocean’s wild species, it also contributes to that pressure, since farmed fish are fed fishmeal made from wild-caught fish. That’s because fish don’t make their own Omega-3s either. Like us, they get them from their diet. Using technology that came out of the space program, scientists have developed a way to cut out the middle-fish from the food chain and harvest Omega-3s for fishmeal directly from the source: algae.

  Activity: Ingenious: The World Has a Receipt Problem Video Questions Mark as Favorite (6 Favorites)

  In this activity, students will answer questions while watching the video The World has a Receipt Problem from the Ingenious series produced by the American Chemical Society. Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates the process of thermal printing on receipts, and the limitations related to the paper that currently prints using leuco dyes. This heat-sensitive ink appears when it reacts with an acid developer embedded in the paper. Scientists are working to develop a new kind of thermal receipt paper, that can use the same printers, however it offers many additional benefits and potential uses.

  Video: Ingenious Video 7: The World has a Receipt Problem Mark as Favorite (7 Favorites)

  The receipts you take home from the store – or stuff in your bag, or lose in your car -- employ a printing method that’s been around since the 1970s. Thermal printing involves heat-sensitive inks called leuco dyes that show up when they react with an acid developer embedded in the paper. Not only do these inks fade easily, but receipts that use them aren’t recyclable, and could even be dangerous to your health. Taking a cue from a failed experiment, scientists are developing a new kind of receipt paper that will use the same thermal printers without leuco dyes. Instead of acid developers, this paper is coated in reflective microspheres that collapse under heat, allowing regular ink underneath to show through.

  Lesson Plan: Acting Out Atomic Structure Mark as Favorite (1 Favorite)

  In this lesson, students will model the location and behavior of protons, neutrons, and electrons that make up the structure of atoms, focusing on the first 18 elements on the periodic table. Students will model different elements first by adding protons and neutrons (colored balls) to make the nucleus (a basket). Then, the students themselves will represent the electrons that are always moving around the nucleus yet remaining within their designated energy level. This activity is easiest to complete outside or in a large open room to allow for enough room.

Finally, the students will then apply their knowledge of the emission spectrum to how the composition of stars is determined.
