Lab Thinking

Date

• Period C: Thursday, September 4th

Lab Questions

• What is the beginning question?
• How will I conduct the investigation?
• How will I stay safe?
• What observations and measurements did I make?
• What can I claim? What evidence do I have to support the claim?
• How do my ideas and results compare with others and to the literature?
• How have my ideas changed?

Scoring Criteria

• Can the beginning questions be potentially answered by the results of the lab?
• What is the quality of the data and observations?
• Are the claims a direct result of the data and observations?
• How well are your data and observations used in your evidence?
• Are the claims backed up in the evidence?
• How well does the student answer all of the questions asked in the lab report write-up for this experiment?
• How well does the student analyze the data and observations to make the experimental measurements of observations meaningful?
• Do the results of the experiment come close to the accepted values or identify an unknown compound correctly or show an accepted comparison, trend, etc.?
• In the reflection and readings how many sources are used and how are they connected?
• Do the student’s reading and reflection discuss the student’s initial questions? Do they aid the student’s claims and evidence?
