"I didn't mean to" and "It wasn't my fault" are two statements that have no place in the lab. If someone is hurt or equipment is broken, these statements cannot undo the harm.
Horse-play will not be tolerated. If it occurs, those involved will be disqualified from the lab and given a zero for the assignment.
Lack of pre-lab preparation is the main threat to safety in our lab. If you and your group are unprepared, you will be unsure of yourself, waste time, and have a good chance of making a mistake that leads to a problem.
At the beginning of each lab period, you will be given a chance to ask questions. If you are unsure of some procedure, now is the time to ask. Always pay close attention to any verbal instructions given at this time.

Remain calm! A minor problem quickly becomes a major one if you don't.


Lab Safety Equipment:


High School Science Labs:

  • The scientific method can't be learned following cookbook-like directions.
  • The purpose of a lab experiment is to test a hypothesis. In most of our labs, you will be given a question or a hypothesis to design your own procedures to test.
  • A Lab Key is provided for the more complicated labs. The Key is provided for your research. It might provide all the information needed to design your lab.
  • To be successful in your laboratory experience, know how to:
  • Here are detailed lab objectives from Rice University.

Prelab Preparation:

caution You are not prepared for a lab until your plan
is neatly written on a Lab Report Form.


Planning An Experiment:


Lab Station Clean-Up: Clean-up

Chemical Storage:
The more exotic the chemicals, the more important proper storage.
This page provides basic storage information.
