Are mistakes or errors valuable to a
scientist?
ESSENTIAL QUESTION
Distinguish between an observation and an inference
Conduct an inquiry to determine what happens when a “ghost” crystal is placed in water.
Practice making observations and inferences about the “ghost” crystal.
TODAY’S GOALS
QUESTIONS
CLAIMS
EVIDENCE
Shoulder Partner ActivityReview the scientific method by completing the graphic organizer.
Check and correct your answers!
Today we are going to focus on the process of making observations!
Let’s just see how observation you really are!
Observations involve all five senses. You may use tools to make an observation known as measurements.
Evidence gathered through observations is called data.
Observations often lead to inferences.
An inference is a logical interpretation based on observations and prior knowledge.
Let’s look at an example.
List some observations and inferences about the man in this picture.
List some observations and inferences about the face in this picture.
Study the cartoon below. Classify the statements below as observations and inferences.
The ant has two antenna. The sign is shaking.The ant can read. The sign was blown over.The ant is worried. The sign is heavy.The ant is perspiring. The ant is under the sign.
Are mistakes or errors valuable?
Will it be valuable to find out your “claim” (hypothesis) from the ghost crystal lab is wrong?
