    Video: Video 6: RAMP (For Teachers)

    As a teacher, there are steps you can take to make sure your students are as safe as possible while exploring and experimenting in the lab. In this video, we discuss some ideas to help you to set up a safe lab experiment. We use RAMP, the acronym for lab safety. RAMP stands for Recognize hazards; Assess risks; Minimize risks and Prepare for emergencies. RAMP is a simple yet powerful tool to help you prepare for and safely carry out any lab activity with your students.

    Video: Video 3: How to Dress for the Lab? And what about Personal Protective Equipment (PPE)?

    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 2: Safety Data Sheet (SDS)

    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 1: Safety Mindset

    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.

    Lab: An Environmental Impact Study

    In this lab, students will test a water sample which comes from a local zoo, where, it is reported that many bird eggs are not hatching. Students will test the water for the presence of multiple ions. Once the type of ion in the water is determined, students will write balanced equations to illustrate their findings. Students will also conduct a serial dilution to determine the concentration, or molarity, of the ion in the water sample. This molarity will be compared to known values to determine if the materials in the water are at an unhealthy level.
