Aerosol Activity: Tic-Tac-Toe

Objective:

Recall aerosol facts from unit.

Instructional Delivery:

Whole group

Activity:

1. Organize the classroom to form two teams.

2. Draw a large tic-tac-toe board on the chalkboard. Allow the students to name their team so that a point method can easily be monitored.

3. Use the tossing of a coin to determine the indicator per team. Example: When tossing the coin, Heads can be "o" and Tails can be "x".

4. One player from each team will compete against the opposing team player to answer a question. The opponent who answers correctly will go to the board and mark appropriately. The participant can consult with team players on where to place the mark. Marks can be made by using chalk or magnetic "o's" and "x's".

5. It is recommended that the students be allowed to use their trading cards during the game, but this is an option.

6. More questions can be generated from other lessons and/or the glossary.
