IPS Exam

A Study Guide by Dr. Dre

Exams Days

Day 1: Calculations, Measurement, and Graphing

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

Nurse extention *2828

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

  1. Fire extinguisher
  2. Fire blanket
  3. 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
  1. could cause an exothermic (outside heat) reaction
  2. 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

Scientific Method
  1. Identify the problem
  2. gather info
  3. form a hypothesis/ theory
  4. test theory leads to experiment
  5. analyze data
  6. 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)
