2009 4-H National Youth Science Day Experiment

Provides an opportunity to "explore space" with the help of geographic information systems (GIS). In two separate activities, you will apply geospatial thinking and use GIS to gather data, make maps, and analyze the "whys of where" as you investigate real-world problems that are relevant to your own community.

Health monitoring using a wearable device is an interesting engineering problem. The idea is to connect an instrument that measures signals from your body (biological signals) and converts those signals to data that then can be analyzed. The problem for this challenge is to design a wearable device that tracks biological data (pulse rate and movement) and uses this to provide feedback on the activity level.

Explores how robots can be used to protect the environment while offering a glimpse into the future of science, technology, engineering, and math.

Participants will understand that yeast can break down sugars through a process called fermentation, releasing carbon dioxide gas and ethanol (which can be used as a “biofuel”). Fermentation is generally, the process by which organisms like yeast break down substances for energy without using oxygen. In our experiment, the fermentation of sugars by yeast produces energy for the yeast and releases carbon dioxide and ethanol as waste products.
