Writing A Lab Report
Observation Skills
Introduction
 Observation is very important when
investigating chemical concepts. Students must
gain experience using hands-on inquiry
activities that promote deeper understanding.
It is important that they be able to practice
writing what they see, smell, or hear while
conducting an experiment. It is also necessary
to practice creating hypothesis and investigating
to decide if the hypothesis is correct or
incorrect.
