What is the teacher doing?

What are the students doing?

Lab Safety Contract (Day 1) Pass out copies of CCS Lab Safety Contract Read and discuss Lab Safety Contract with students Direct students to have the contract signed by their parent/guardian and returned to the teacher. It is very important that students not actively participate in lab activities until the form has been signed, returned to the teacher, and held on file.

Lab Safety Contract (Day 1) 1. Read the CCS Lab Safety Contract and discuss why lab safety is important. 2. Students take the contract home so that it can be signed by a parent/guardian and returned to the teacher before participating in any laboratory experiences.

Lab Safety Jeopardy (Day 2) Facilitate the Lab Safety Jeopardy game. Click Here to access the Jeopardy Game. Click on the “slide show” button to begin.

LAB SAFETY JEOPARDY – TEACHER PAGE The Jeopardy Game can be accessed on-line. Click here. 1. Group students into groups of 3-4. 2. Decide which group will go first and have that group pick a category. 3. Click on the point value for that category and a question screen will come up. 4. Students will work in the group to determine an answer to the question. If the group gets it correct, they win the points. If the group gets it wrong, another team can answer the question correctly and win the points. 5. Once the question has been answered you can double check that they have answered it correctly by clicking on the house at the bottom of the page.

Safety Charades (Teacher notes) Equipment a stopwatch or other timing device a notepad and pencil for scorekeeping safety rules on slips of paper a basket or other container for the slips Preparation Divide the players into two teams, preferably of equal size. Members from each team will take turns being timer and scorekeeper. To Play Each round of the game proceeds as follows: A player from Team A draws a phrase slip from the basket. After he/she has had a short time to review the slip, the timekeeper for team B notes the time and tells the player to start. Team A then has three minutes to guess the phrase. If they figure it out, the timekeeper records how long it took. If they do not figure it out in three minutes, the timekeeper announces that the time is up, and records a time of three minutes. A player from Team B draws a phrase slip from the basket, and play proceeds as above. Normally the game continues until every player has had a chance to "act out" a phrase or until the class is over. The score for each team is the total time that the team needed for all of the rounds. The team with the smallest score wins the game. NOTE:

You can also have this be done as individuals rather than teams. In this case have students draw a slip from the basket, give everyone five – ten minutes to come up with how they will act out the safety procedure. Then have them write out how they are going to act out this safety rule. Take turns acting out the safety rules. If students find some of the rules difficult to guess, have others in the class act out how they would have shown this rule.
