  Video: Video 1: Safety Mindset Mark as Favorite (17 Favorites)

  The chemistry lab is an amazing place! Through experiments and demonstrations your high school students have been discovering that chemistry is more than just a collection of facts and formulas-- it’s a way of observing and understanding the very real properties of matter all around them. However, the lab can also be a dangerous place. Contrary to what your students might have seen in films and TV, safety is a core value of chemistry—it is essential to everything they do in the lab. It begins with their mindset, the attitudes and beliefs they bring to class with them every day. Use this video to introduce your students to elements of safe importance of safety mindset in the chemistry lab.

  Video: Video 2: Safety Data Sheet (SDS) Mark as Favorite (17 Favorites)

  Preparation and planning are key to working in the chemistry lab. To be prepared, your students must understand the hazards of any chemicals they will be working with. The place to find that information is the Safety Data Sheet or SDS. The SDS provides detailed information about the properties of a chemical, its hazards, and how to protect yourself from those hazards. Use this video, to guide your students through 16 sections of the SDS for isopropyl alcohol to demonstrate importance of SDS information.

  Video: Video 3: How to Dress for the Lab? And what about Personal Protective Equipment (PPE)? Mark as Favorite (18 Favorites)

  Wearing personal protective equipment (PPE) for short is one of the main ways for you and your students to stay protected from injury in the lab. PPE includes things like goggles, gloves, lab coats or aprons. These are designed to protect eyes, hands and skin, as well as clothing, from exposure to chemicals. PPE is the most obvious way of preventing contact with chemicals--but it is not the first line of defense. Use these video to teach your students that before they put on any PPE, why they should dress properly for lab.

  Video: Video 4: Preparing for Emergencies Mark as Favorite (0 Favorites)

  There is an old saying that you should always plan for the best, but prepare for the worst. This is good advice in the lab as well. Use this video to teach your students about two lab emergencies that carry a high risk of injury--spills and fires. The videos describes concrete steps to prevent these emergencies and goes over some of the safety equipment used to deal with them.

  Video: Ingenious Video 3: This Sandwich Will Save Your Life in an Arc Flash Mark as Favorite (3 Favorites)

  It’s never fun when your clothes catch on fire. And while “stop, drop, and roll” may be a good idea sometimes, in more extreme cases, you need a better plan. Every day, industrial workers, firefighters, and soldiers risk fiery situations that might seem hard to imagine. In an arc flash event, for one, temperatures can jump to metal-melting levels in milliseconds. How can anyone possibly survive that? Well, take a tip from a club sandwich, because it’s all about the layers. The composite fabrics that protect life and limb in these situations rely on some incredible, multilayered chemistry, including the ability to quickly form a protective carbonaceous crust around the wearer.

  Video: Ingenious Video 7: The World has a Receipt Problem Mark as Favorite (3 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.

  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.
