  Video: Video 1: Safety Mindset Mark as Favorite (49 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 (12 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 (13 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 (11 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.

  Exothermic & Endothermic, Specific Heat, Density, Phase Changes | High School

  Lab: Chemistry is Cooler Stress Test Challenge Mark as Favorite (66 Favorites)

  In this lab, students will design and build a device capable of insulating an ice cube submerged in boiling water for two minutes. In this open-ended inquiry based activity, students will be required to critically think about structure and function of the materials they wish to use to build a device to solve a complex real-world problem. Students must consider the thermal properties of the materials, density, and the need to form a non-permeable barrier between the ice cube and the boiling water.

  Demonstration: Understanding the Discrepant Reactivity of Copper in the Presence of Strong Acids Mark as Favorite (8 Favorites)

  In this demonstration, students practice their observation skills during the additions of different acids to two test tubes containing copper. The activity is structured to allow students to make thoughtful remarks about what they observe, using rich indicators of both chemical and physical properties and changes. In subsequent lessons on new concepts, students can reflect back on their observations to rationalize the discrepant results of the reactions in the demonstration.

• 

  Molecular Structure, Intermolecular Forces, Physical Properties | High School

  Lab: Solubility Plays a Role: Making Seitan from Flour Mark as Favorite (13 Favorites)

  This lab offers insight into a practical aspect of solubility and demystifies a common ingredient, wheat flour.
