Driving Question: How can we work safely with chemicals and equipment?

Labeling

1) Vocabulary: Match the following terms to their definitions

Drag labels to their correct position on the image

threshold limit value

MSDS or SDS

flashpoint

evaporation rate

CAS #

solubility

Where have you seen this before?

​

​2) Hazard Diamond

Open Ended

2a) Where will you see this in class?

2b) Should you be more concerned if you see a 1 or 4 in the blue diamond? Why?

4) SDS

Magnesium ribbon

​​Hydrochloric acid

​​Sodium hydroxide

copper (II) sulfate

Open Ended

4a) Skim through the SDS and take note of the 16 sections it contains. Record the title of 4 sections below.

Use your selected SDS to answer the following prompts. Be sure to label each answer with the number and letter of the prompt:

4b) Which pictograms did you see associated with your chemical? What should be done if you come in contact with this chemical? 

4c) What is the CAS number?

4d) What is the flashpoint? 

4e) What is the threshold limit value?

4f) What is the fire hazard?

4g) What are the disposal concerns?

While most of these rules are "Common sense," some are specific. ALL of these rules must be followed during a lab.

​5) Safety Contract

Open Ended

5) Safety Contract

5a) Skim the Safety Contract and circle or highlight what you would consider the top 5 most important rules to follow.

5b) Knowing yourself, which 3 rules will be most difficult for you to follow? Summarize them below.

5c) Read one rule aloud to the class and explain why you think it is important.

​Read the lab procedures linked here For each lab, identify at least three SPECIFIC (not just general) rules from the safety contract that might apply. Do not use a rule more than once. Type your answers on the next slide.

5) Safety Contract

Open Ended

5d) Read the lab procedures linked here. For each lab, identify at least three SPECIFIC (not just general) rules from the safety contract that might apply. Do not use a rule more than once. 

​Fill in answers on the provided handout.

6) Safety Video

Instructions: Construct a safety poster by developing a rhyme or slogan and drawing a corresponding picture of a safety rule from the provided Flinn Safety Contract.

Special Considerations: Artistic ability is not graded, however, the poster must be neat, colored with multiple colors, creative, authentic (I shouldn’t be able to Google search and find a replica) and done by hand. Your name, period, and rule number must be on the back! See rubric handout for full explanations of how points are earned.

7) Safety Poster

​8) Classroom Safety Map

On your handout, label the map with the safety features found around the classroom.

9) Safety Demonstration

Fill in the handout prompts regarding the safety demonstration.
(If you were absent, ask a friend to describe the demonstation)
