SCIENCE SAFETY ASSIGNMENTS-ALL GRADES

INTRODUCTION:

It cannot be emphasized enough: Safety should be the number one consideration in a Science lab. Always. This assignment will help students learn to behave properly in the Science lab. In addition, students who work carefully will be well-prepared to carry out lab activities and, perhaps more importantly so some, write and pass the safety test. Recall that students must write the safety test until they achieve 80% before being allowed to do labs. Students who behave inappropriately during labs will be given a warning, then referred to their counselor and principal/vice-principal.

THE ASSIGNMENTS:

  1. THE SAFETY RULES

INSTRUCTIONS: Read the safety rules in the Safety Booklet given to you by the teacher. Also read the safety rules in your textbook. Learn any symbols that are given in your textbook. Answer the questions on pages 2 to 5.

ASSIGNMENT 4: LABORATORY DOS AND DON’TS

Identify what is wrong in each picture of the laboratory activities below. There may be more than one thing wrong in each picture. Find as many unsafe activities as possible.

assignment 5: SAFETY POSTER ASSIGNMENT

  • To create a science safety poster in which you show at least10 safety rules being broken in a Science Laboratory. See the example below. The poster is to be done on one side of one piece of paper. The size of the paper is flexible. Generally, the larger the piece of paper, the neater your work can be.
  • On a separate sheet of paper, the rules that have been broken are to be stated, and what the correct procedure should have been will be clearly written. For example:

“In the lower right hand corner, a student is pouring water into a large container of acid. The proper procedure is for small amounts of acid to be poured into large amounts of water.”

  • Hint: Do not make all of the rules being broken too obvious. You will be competing with each other later by exchanging your posters and seeing if you can find all of the broken rules in your peers’ posters. If you can find more of the broken rules in their poster than they can in yours, you win, and are eligible for extra credit! You should include on your poster numerous examples in which no rules are broken to “mislead” your opponents.
