Ideas to be Developed
We will begin this science unit, which has a particular focus on chemistry, with an introduction to safety. By way of a safety contract, we will discuss safety issues that we may face throughout this unit. The students will then have the opportunity to observe an experiment and identify safety equipment and procedures that should be considered and why.

Key Words
Chemistry- the study of the elements, the compounds they form, and the reactions they undergo.

Materials Required
  • Safety Contract
  • hot plate
  • tin can (with bottom just covered with water)
  • bowl of cold water

Procedure
  • Go over the complete student lab safety contract.
  • Students will read over the procedures for this experiment and determine what safety precautions/ equipment should be employed.
  • Students will observe the “Temperature vs. Pressure in a Can” experiment and take note of safety precautions taken.

Observations
Students will observe the experiment being done by the teacher and identify the safety equipment and precautions that were taken in doing this experiment.

Summary

Questions
1. What safety equipment and/or precautions did the teacher employ in
order to carry out this experiment? Why were these used?

 

 

2. What precautions were missed?

 

 

3. What did happen/ what could have happened as a result of not following these safety strategies?
