Children ages 9 and up continue to explore and understand genetics, biotechnology, and genetic engineering. Members of this age group examine social and scientific issues related to new technologies, as well as their personal values and those of others. Older youth also define, describe, and plan environmental stewardship activities related to biotechnology and the environment. Many of the concepts are very abstract and complex for young, concrete thinkers. However, clear understanding that sugar fed the dough to make the yeast rise would be sketchy at best.
Children are very inquisitive.
In addition to understanding children's abilities and potential, the adult leader working with this project will need an extensive background with scientific concepts to address questions as they arise and assist children in searching for the answers. Some of the hands-on activities could be appropriate for children younger than 9 if they are subdivided into parts that are shorter than the suggested 45 minutes. One section lists razor blades, tweezers, and eye droppers for an activity with 5 year olds. Razor blades, I assume would not be accessible. Tweezers and eye droppers are interesting to young children, but the children may need some practice to get their small hands to cooperate for the correct measurements.
