Laboratory Safety Instructions

For Every Lab

Goggles must be kept ON YOUR FACE until Mr. Leeds says to put them away
Report ALL accidents/spills to Mr. Leeds immediately
Always use common sense

In Case of Emergency

The extension number for the nurse is 2828.

Safety Equipment in Classroom

Fire extinguisher

Fire blanket

Eye wash/shower


Never taste chemicals

Always WAFT liquids to detect odor


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


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 opoen 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 reaction
  2. water is less dense (lighter) than acid so it will sit on top of acid and could splash out

End of Experiment

Make sure burner is capped and flame is out


Chapter 1

Scientific Method

  1. Identify the problem.
  2. Gather the information.
  3. Form a hypothesis/theory.
  4. Test the hypothesis (experiment)
  5. Analyze the death.
  6. Draw/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
  • One liquid turns warm (A) and the other turns cold (B)


  • Observations
  • Inference
  • Hypothesis
  • Control Group
  • Experimental Group
  • Control Factors
  • Indicator
  • Volume
  • Volume Displacement Technique
  • Mass
  • Meniscus

LAB: Heating Baking Soda

Purpose: To observe and reaction that occurs when the baking soda is heated.

1.2 Volume Notes

Single Pan Balance Notes

LAB: Measuring Volume by Displacement of Water

Purpose: To use the volume displacement of water method to discover the amount of dry sand that is sand and air space.

LAB: The Sensitivity of a Balance

Purpose: To discover the sensitivity of your balance. Also, to see if you mass the same object repeatedly, will you find the same mass.

Chapter 2


  • Histogram
  • Conservation of Mass
  • Laws of Nature

LAB: The Mass of Dissolved Salt

Purpose: To discover if the mass of the salt will decrease when dissolved in water

LAB: The Mass of Ice and Water

Purpose: To determine if when ice melts does its mass change along with its volume.

LAB: The Mass of Copper and Sulfur

Purpose: Does the total mass of copper and sulfur change when they are heated together?

LAB: The Mass of a Gas

Purpose: To discover when a solid and liquid produce a gas, will the mass change change.

Conservation of Mass

Chapter 3

Properties of Substances and Properties of Objects

  • Characteristic Properties
  • Property of Object
  • Property of Substance
  • Density

LAB: Mass and Volume

Purpose: To discover if the mass of a cubic centimeter object will depend on its shape of the substance that it is made of.

LAB: The Density of Solids

Purpose: To use density to compare 3 metal objects to see if they are made of the same substance.

LAB: The Density of Liquids

Purpose: To use density to compare 2 liquids to see if they are the same substance.

LAB: The Density of a Gas

Purpose: To produce and collect a gas in order to accurately find the density of the gas.
