Lab Safety: Everyone Is Responsible! Safety In the Science Lab Rules and Symbols

Objective • SWBAT understand, evaluate and practice safe procedures for conducting science investigations. (5. 1. 12. D. 3)

Essential Questions • Why do you need to understand safe procedures in the science classroom and laboratory? • How do you practice safe procedures in the science classroom and laboratory?

List 3 Mistakes Made by the Students

Safety First • Science is a hands-on laboratory class. • You will be doing many laboratory activities, which require the use of hazardous chemicals and expensive lab equipment. • Safety in the science classroom is the #1 priority. • To ensure a safe science classroom, a list of rules has been developed and provided to you in your student safety contract. • These rules must be followed at all times. • A signed lab safety contract is required to participate in labs.

No Horseplay!

General Safety Guidelines 1. Be Responsible at All Times. No horseplay, practical jokes, pranks, etc. 2. Follow all instructions carefully. 3. Do not use lab equipment until instructed to do so. 4. Food, drink, and gum are not allowed in the science classroom.

What’s Wrong With This Picture?

What’s Wrong With These Statements? • Kristen says that her teacher is solely responsible for preventing laboratory accidents. • Kera started the lab activity before reading it through completely. • Allysa decided to do a lab activity that she read about in a library book before the teacher came into the classroom. • Jordan says that the safety goggles mess up her hair and give her raccoon eyes. She refuses to wear them. • Lizeth and Soraya accidentally break a beaker full of some chemical. Instead of risking getting in trouble they quickly clean up the mess with paper towel and throw it in the garbage.

What To Do In An Emergency If there is a fire or fire alarm • Quietly get up and push in your chair. • Walk toward the outside classroom door. • Turn Right to go down stair well • . Stay with the class • Attendance will be taken, you will receive a consequence if you are missing during and/or after the fire drill • Remain silent throughout the entire alarm so that all people can hear important directions.

Any Questions? REMEMBER: • Carefully read through the entire safety contract and sign. • Have your parents read and sign your safety contract. • Study for the safety test later this week!
