-Justification Justification Justification - "connects the dots" between evidence & claim and/or

- ties the claim and evidence to important science ideas (like evolution, osmosis) "What does the evidence mean?" "What else do we know about this?"

Before we can experiment on plants or animals or chemicals we need lab safety

List the offenses in this science lab. Pass around team whiteboard to record Laboratory Safety BEFORE THE LAB

Dress properly during a laboratory activity. Long hair, dangling jewelry, and loose or baggy clothing are a hazard in the laboratory.

Long hair must be tied back, and dangling jewelry and baggy clothing must be secured. Shoes must completely cover the foot. No sandals allowed on lab days.

Which Ms. MorrisOHearn is ready for the lab? Which shoe is appropriate?

Dont touch, until told When first entering a science room, do not touch any equipment, chemicals, or other

materials in the laboratory area until you are instructed to do so. Wheres the safety

equipment? Know the locations and operating procedures of all safety equipment including: first aid kit(s), and fire extinguisher. Know where the fire

alarm and the exits are located. Fire Extinguisher is by the lab section First aid will be on the on the board No food

Do not eat food, drink beverages, or chew gum in the laboratory. Do not use laboratory glassware as

containers for food or beverages. Know the directions Follow ALL written and

verbal instructions carefully. If you do not understand a direction or a part of the procedure, ASK YOUR TEACHER BEFORE

Do not panic. Know what to do in a drill Know what to do if there is a fire drill during a laboratory

CLEANING UP Wash your hands Keep hands away from face, eyes, mouth, and body while using chemicals or lab equipment. Wash your hands with soap

and water after performing all experiments. Dispose of chemicals Dispose of chemicals in waste containers, not down the sink

Cleaning 1)What do you do with the chemicals that you have finished with? 2) What should you do before you leave the lab?

Read the safety contract and sign it. Copy the sentences, no printing. See me if you wear contacts Change I have read pg 155-156 to I saw Ms. Morris safety power point

I will be holding you to your word! To do - Pick up lab contract
