Making Observations of Matter What do chemists do?
Observations • Use the procedures of pages 18 and 19 in the Small Scale Lab Manual to make observations of the five different examples of matter. • Use the hand lens to better visualize both the macroscopic and microscopic levels of matter. • Make sure to record your observations on the table provided (and attach the table into your journal).
Hypotheses For each other five cases, write a hypothesis to explain your observations. • What is the structure of the inside of the newspaper? • What determines the shape of the crystals? • How does water change the rock salt to cause it to conduct and electric current? • How are the attractive forces different in water compared to mineral oil? • What caused iodine to react differently in water than in mineral oil?
Questions For each of the five cases, write as least one question you still have about the composition and behavior of matter.
