Observations and Inferences

ObjectivesObjectives

1. Collect and record data by making observations.

2. Analyze and interpret information by detailed observations and accurate measuring.

3. Communicate valid conclusions.

EngagementEngagement Observe:

What similarities and differences are there between these two cans of soda?

Make observations about the cans of soda using a Venn diagram:

How are they similar?How are they different?

Engagement activity: Engagement activity: ProcedureProcedureMake observations about the

PART 1Pour 120 ml tap water into the 250

ml beaker.Add 1 teaspoon of baking soda.Add several raisins.Add 15 ml vinegar.Observe what happens for several

minutes. Record your observations on part I of your lab sheet.

Add another 20 ml vinegar, record observations.

Part IIPart IIOn your lab sheet under part II: Make a drawing that shows what

happened to the raisins in the liquid. Be sure to label the important parts.
