ABOUT THE 4-H SET INITIATIVE• 4-H is non-formal instruction organized along an
experiential path: Experience
Reflect
Generalize
Apply
• Brings cutting-edge research and resources of the land-grant university system to youth
• Hands-on
• Connected to life-skill development
WHY SCIENCE?
• Youth in the US are not prepared with the necessary science, engineering, and technology knowledge or workforce skills to compete in the 21st century.

WHAT IS SCIENCE?• According to Webster's New Collegiate
Dictionary, the definition of science is "knowledge attained through study or practice," or "knowledge covering general truths of the operation of general laws, esp. as obtained and tested through scientific method [and] concerned with the physical world."
• Science includes: Observing what is happening
Predicting what might happen
Testing predictions under controlled conditions
Trying to make sense of our observations
KITCHEN CHEMISTRY• Science workshops can be conducted as:
Stand alone activities
Short-term after-school programs
Long-term after-school programs
Special day-long events for school holidays/out-of school time
Summer enrichment camps
KITCHEN CHEMISTRY
• Use common household materials
• Set clear expectations for student behavior
• Have sufficient supervision
KITCHEN CHEMISTRY• Favorite Activities That You Can Eat– Study yeast and make bread or pizza
(biology)
– Study the chemistry involved in making peanut brittle (while you make it)
– Experiment with making cookies out of vegetable shortening, margarine, and butter
– Make ice cream in a bag – discuss the chemistry involved in solidifying the ice cream
KITCHEN CHEMISTRY• Favorite Activities (non-edible)– Mystery Powders (test properties of four white
powders to determine what they are)
– Science Inquiry at Its Best (explore chemical reactions by mixing various powders and liquids to note change in color, temperature, volume, etc.)
– Invisible Ink (write a secret message to a friend, trade and reveal messages)
