Prior to beginning a lab activity, it is best to –

​1. ACT RESPONSIBLY WITH YOUR BEST CLASSROOM BEHAVIOR. FOOLING AROUND OR ENGAGING IN PRANKS OR PRACTICAL JOKES COULD ENDANGER YOU OR YOUR CLASSMATES.  
2.BEING PREPARED FOR LAB WORK INCLUDES WEARING SAFE CLOTHING. DON’T WEAR LOOSE OR BAGGY CLOTHING THAT COULD KNOCK SOMETHING OVER OR CAUSE YOU TO TRIP AND FALL. TIE BACK LONG HAIR. WEAR ONLY CLOSE-TOED SHOES, NOT SANDALS, FLIP-FLOPS OR HIGH HEELS. USE AN APRON IF YOUR TEACHER INSTRUCTS YOU TO DO SO.  
3. ALL PERSONAL ITEMS SUCH AS BACKPACKS, JACKETS, BOOKS, WATER BOTTLES, ETC. NEED TO BE PUT AWAY BEFORE STARTING A LAB ACTIVITY.  ONLY LAB MATERIALS, INSTRUCTIONS, SCIENCE JOURNAL/IPAD, AND A WRITING IMPLEMENT SHOULD BE ON A LAB TABLE.  
4. LISTEN CAREFULLY TO YOUR TEACHER’S INSTRUCTIONS SO YOU CAN FOLLOW THOSE AND THE WRITTEN PROCEDURES. IF YOU DO NOT UNDERSTAND A DIRECTION OR PART OF A PROCEDURE, ASK FOR HELP. NEVER DO ANYTHING IN THE LABORATORY THAT IS NOT CALLED FOR IN THE LABORATORY PROCEDURES OR BY YOUR INSTRUCTOR.  
5. DO NOT TOUCH ANY EQUIPMENT OR LAB MATERIALS UNTIL INSTRUCTED TO DO SO. USE MATERIALS ONLY AS INSTRUCTED.  
6. PERFORM ONLY APPROVED EXPERIMENTS UNLESS YOUR TEACHER GIVES YOU PERMISSION TO DO SOMETHING DIFFERENT.  
7. DO NOT EAT FOOD, DRINK BEVERAGES, OR CHEW GUM IN THE LABORATORY. DO NOT TASTE LAB MATERIALS. DO NOT USE LABORATORY GLASSWARE AS CONTAINERS FOR FOOD OR BEVERAGES. FOOD ITEMS SHOULD NOT BE BROUGHT TO THE LAB.  
8. DO NOT TOUCH YOUR FACE, EYES, OR MOUTH WHILE USING SCIENCE MATERIALS.  
9. USE SAFETY GLASSES OR GOGGLES WHEN YOU ARE TOLD YOU NEED THEM. KEEP THEM ON THROUGHOUT THE EXPERIMENT, UNLESS YOUR TEACHER TELLS YOU THAT YOU CAN TAKE THEM OFF.  
10. FOLLOW YOUR TEACHER’S INSTRUCTIONS FOR CLEANUP. CLEANING LAB MATERIALS AND WORK AREAS IS PART OF COMPLETING A LAB ACTIVITY. WHEN YOU RETURN CLEANED EQUIPMENT, NOTIFY YOUR TEACHER IF IT’S CRACKED OR NOT WORKING PROPERLY.  
11. MAKE SURE YOU KNOW WHERE WASTE MATERIALS GO. BE SURE TO PUT THEM THERE.
​12. WASH YOUR HANDS WITH SOAP AND WATER AFTER PERFORMING ALL EXPERIMENTS.  
13. NOTIFY YOUR TEACHER RIGHT AWAY IF ANY ACCIDENT, INJURY OR DANGEROUS CONDITION HAPPENS AND WAIT FOR TEACHER INSTRUCTIONS BEFORE DOING ANYTHING ELSE ABOUT IT. THIS INCLUDES SPILLS AND BROKEN GLASS.  
14. ASSUME CHEMICALS USED IN YOUR LABS COULD BE DANGEROUS IF USED IMPROPERLY. YOUR TEACHER WILL GIVE YOU INSTRUCTIONS ON THE PROPER METHOD FOR TOUCHING OR SMELLING ANY CHEMICALS IF THAT IS NECESSARY FOR THE LAB. OTHERWISE, AVOID TOUCHING OR SMELLING CHEMICALS.  
15. IF YOUR LAB INVOLVES WORKING WITH LIVE ANIMALS (INCLUDINGINSECTS), MAKE SURE YOU UNDERSTAND AND FOLLOW YOUR TEACHER’S DIRECTIONS FOR HOW TO HANDLE THEM. WEAR GLOVES AND HANDLE ANIMALS WITH CARE. LET YOUR TEACHER KNOW RIGHT AWAY ABOUT ANY BITES, SCRATCHES OR OTHER AGGRESSIVE BEHAVIOR.  
16. USE TWO HANDS TO CARRY A MICROSCOPE--ONE HAND ON THE ARM, THE OTHER UNDER THE BASE. 
17. FOLLOW INSTRUCTIONS AND DIRECTIONS WHEN WORKING WITH PRESERVED SPECIMENS AND DISSECTION MATERIALS. USE EXTRA CARE WHEN USING SHARP TOOLS, SUCH AS SCALPELS AND SCISSORS. MAKE CUTS AWAY FROM YOUR BODY.  
18. STAY OUT OF STORAGE AREAS, DRAWERS, AND CUPBOARDS UNLESS YOUR TEACHER GIVES YOU PERMISSION TO ENTER OR RETRIEVE SOMETHING.  
19. HANDLE ALL GLASSWARE WITH CARE. USE A HOT PAD OR TONGS TO PICKUP HOT GLASSWARE. IF GLASS BREAKS, NOTIFY YOUR TEACHER FOR INSTRUCTIONS BEFORE CLEANING IT UP.  
20. USE HEAT SOURCES ONLY AS INSTRUCTED. DO NOT LEAVE A HOTPLATE OR LIT BURNER UNATTENDED. 
21. LEARN WHERE THE SAFETY EQUIPMENT (FIRE EXTINGUISHER, FIREBLANKET, EYEWASH STATION, SAFETY SHOWER, FIRST AID KIT) IS LOCATED AND HOW TO USE IT. KNOW WHERE THE EMERGENCY EXITS ARE LOCATED AND WHAT TO DO IN CASE OF AN EMERGENCY OR DRILL.

Everyone is responsible for completing the lab safety contract in order to participate in an experiment or lab in the classroom.  Remember that there are risks involved in doing science and we must be responsible for keeping ourselves and our classmates safe. IMPORTANT: Please download and print a copy of the contract, fill it out, sign it, and have your parents read and sign it as well.
If a student does not have a signed and completed lab safety contract they will not participate in classroom labs or experiments.  They will be given an alternative assignment and sent to the library to complete it.

Learning Objectives:

• Students will learn how to use a Safety Data Sheets
• Students will learn about the importance of using safety rules and procedures in the lab

You will be responsible for reading through the appropriate sheet whenever we use chemicals during a lab.  It is important to understand how to use the chemical properly, what other substances the chemical will react to, and the safety measures to be taken while using the chemical(s).

Together as a class we will be reviewing the Lab Safety Presentation, Safety Contract and Rules.  It is important that you take this very seriously and listen carefully.

1. Read through the rules above as a team. 2. Together make a list of both the rules that are being followed (and the name of the person who is following them) and the rules that are not being followed (and the name of the person who is not following them).   3. Each person should copy the list down in their Science Journal, under the title of Lab Safety. 4.  Be ready to share out your findings.​

Click on the link  for the Chemical SDS sheets.  Individually, decide on one of the chemicals that you would like to learn about.  You will write a short report (in your science journal or in Notability - save it to your One Drive folder and share it with Mrs. Smith) about the chemical and include the following information:

• Name of chemical
• Chemical formula for the chemical (example: Water is H2O)
• Is the substance considered hazardous? If so, what hazards are associated with the substance?
• If it is inhaled, what should you do?
• If it is eaten or swallowed, what should you do?
• If it gets into someone's eyes, what should you do?
• If it catches fire, what should you do?
• At what temperature will it auto-ignite? (explain what it means when a substance auto-ignites)
• At what temperature is it's flash point? (explain what a flash point is)
• At what temperature will it freeze?
• Can it give off toxic fumes?
• How do we clean up this substance if it is spilled?
• What state of material is it typically used in an experiment?
• Based on what you've learned about this substance, what else should we know?

We need to be prepared for possible hazards or possible accidents before we do any science lab.  To practice, we are going to look at a sample lab instruction sheet and identify the possible hazards, what can be done to prevent the hazards, and if the identified hazard happened, what would we do... 

Instructions:  

2. Using the Lab Safety Worksheet, fill it out.  Identify 3 possible hazards, what precautions can be made to prevent accidents from happening, and what the emergency procedures would be if this type of accident occurred.  

USE THE LAB BELOW FOR WHOLE CLASS PRACTICE

Sample Lab: Greenhouse in a Jar Lab–Experiment 1
Question: How does covering the top of a jar affect the temperature inside a bottle when exposed to heat?
Materials:2 clear 2L soda bottles with labels removedTin Foil2 thermometers (these should read at room temperature) 150 W light fixtureRulerStopwatchPencil and string to hang thermometer

Procedure:

2.         Place the 2 liter bottles next to each other side by side about 6 inches away from the lamp.

USE THE LAB BELOW FOR TEAM/INDIVIDUAL ASSIGNMENT

Sample Lab:  Can Crusher
Question: Why does the can crush?
What You Need:

• Empty soda can with tab removed
• Ice water
• Pan
• Mixing bowl
• Tongs
• Stove

1. Rinse the soda can. Then, place a couple tablespoons of water inside it—just enough to cover the bottom of the can.
2. Place the can directly in a pan (use an old pan if you are worried about any damage caused by heating the can) and place on a stovetop burner. Turn the burner to medium–high heat. Allow the water in the can to heat.
3. Fill the mixing bowl with about two inches of ice water.
4. Once the water in the can is boiling (steam will be coming out of the can and you should be able to hear the “popping” sound of boiling water), use the tongs to remove the can from the pan and quickly (without splashing boiling water!) bring the can to the bowl of water, turn it upside down, and immerse the can in the cold water. The can should quickly be “crushed” by the cold water!
5. Still holding the can with the tongs, pull the can out of the water and observe how much water pours out of the can.
6. Tip: If the can doesn’t crunch on the first attempt, repeat the experiment. Consider using a different can, placing less water in the can, making sure the water in the bowl is very cold, or heating the can in pan longer.

1. As a team, pick a rule for each team member to create a poster depicting the rule.  Then individually, pick which rule you will create a poster for.  You will need to include the following elements:

• The rule
• Picture of what the rule looks like when followed correctly
• Poster should be easy to read and neatly drawn
• Remember to write big so people can see the rule from a distance
