People will be asked to observe a variety of traits and do some experiments, creating a database with their responses. Some of the traits are genetically inherited. Some traits are not considered genetic, but may change as people grow older or vary by where people live. Before compiling and sharing the results, make some predictions. Make a graph to see if any patterns emerge.
Youngsters are interested in knowing about others who share their traits.
Share the results once they are compiled. Feel free to add or omit questions or adapt the survey to your needs. Details, procedures, and materials for answering each specific question follow the survey questions. This seemingly simple question can be an interesting exercise in designing a scientific experiment. Encourage everyone to think scientifically and to learn more by experimenting and collecting evidence.
