Acid Rain Investigation

Before the meeting: 

1. Set up the meeting room with tables to provide enough space for the activity. 
2. Lay out the supplies for the activity for each Cub Scout. 

During the meeting: 

1. Have Cub Scouts write “water,” “slightly acidic,” and “acidic” on the pieces of masking tape. 
2. Have Cub Scouts add water to the three jars. Have them completely fill the first container, fill the second one ½ full, and the third one ¼ full.  
3. Ask Cub Scouts to add enough vinegar to the second and third containers to fill them completely. Tell them to put the pieces of masking tape on the appropriate container. 
4. Tell Cub Scouts to put a flower into each jar.  
5. Have Cub Scouts put their jars into their boxes and set aside until the end of the meeting. 
6. At the end of the meeting, Cub Scouts look at their flowers. Ask them if they see any differences in them. 
7. Allow Cub Scouts to take their flowers home and instruct them to examine them after 24 hours. Tell them to write notes on what they see. 
8. At the next meeting, ask Cub Scouts to share what happened to their flowers.
