Day 2: Multiple Choice, True/ False, and Matching (vocab)
Remember: show work, units, and ch. 2 experimental errors
Also check histograms of each lab
Lab Safety
With alcohol burner- roll up sleeves and pull up hair
Goggles on face until Mr. Leeds says to put them away
report all accidents/spills to Mr. Leeds immediately
Always use common sense
Safety Equipment
- Fire extinguisher
- Fire blanket
- eye wash/ shower
Chemicals
- never taste chemicals
- always waft liquids to detect odor
- never waft solids/ powders
- avoid touching chemicals
- always wash hands with soap and water after lab
- **flush skin with water if contact with chemicals occurs** and notify Mr. Leeds
Glass
- hot glass and cold glass look the same
- never use chipped or broken glass
- never use force to remove or insert glass
Alcohol Burners
- roll up sleeves, put up long hair, not just pull back (or you cannot do lab)
- never walk away from a lit burner
- never point the open end of a hot test tube at yourself or someone else
- do not look down into a test tube/ beaker while it is being heated
Diluting Acid
- acid must be added to water
- never add water to acid
- could cause an exothermic (outside heat) reaction
- water is less dense (lighter) than acid so ti will sit on top of acid and could splash out
End of Experiment
- make sure burner is capped and flame is out
- clean-up area and materials completely (or you lose points)
Before Chapter 1
- Identify the problem
- gather info
- form a hypothesis/ theory
- test theory leads to experiment
- analyze data
- form a conclusion
Lab: Reaction in a Bag
- Purpose: To record observations that occur when substances are combined.
- exothermic (outside heat)
- Pressure is created from the formation of a gas
- on liquid makes warm (A + exothermic) other makes cold (B)
