101: Water Properties

The below content replicates the content of the physical exhibit at CSU Spur. It can be used for reference, language translation, and additional accessibility.

Globe A: Making Ripples

Notice how one droplet of water creates many ripples (the ripple effect!). How do multiple ripples interact with each other and where the water meets the land? 

Instructions: Touch the buttons   

Globe B: Making Clouds

Condensation is water vapor changing from gas to liquid on cool surfaces (turn the wheel to the left). Evaporation is liquid changing to gas as temperature increases (turn the wheel to the right to heat up the sun).  

Instructions: Turn left for condensation / Turn right for evaporation 

Globe C: Making Light Bend

When light shines through water, it bends (refracts) and bounces (reflects) in interesting ways. Touch the buttons to see what happens when light passes through still and moving water. 

Instructions: Touch button for light / Touch button to create motion

TOM VILSACK

Chief Executive Officer, World Food Prize Foundation

Effective March 1, 2025, Thomas J. Vilsack, former United States Secretary of Agriculture and Governor of Iowa, will become the first Chief Executive Officer for the World Food Prize Foundation. In this new role, Governor Vilsack will focus on expanding the Foundation’s global network, and will further position the Foundation as a leader in addressing global food and nutrition insecurity, continuing his lifetime of public service.

In 1998, he became the first Democrat to be elected as the Governor of Iowa in more than 30 years. During his two terms as Governor, he created an $800 million, 10-year economic development incentive program—the Iowa Values Fund. His administration worked with schools, medical providers, businesses, faith-based organizations and other entities to expand healthcare coverage to more than 90,000 previously uninsured children.

He became the 30th and 32nd United States Secretary of Agriculture, from 2008-2017 and 2021-2025, respectively. Only five people in U.S. history have served in the Cabinet longer, and during his tenures, the United States Department of Agriculture set records for U.S. agricultural exports and provided food assistance to millions of Americans. He helped expand food and nutrition access through summer feeding programs for children and additional support for fruit and vegetable purchases through the Women, Infants and Children (WIC) program. As Secretary, he worked to develop new and superior markets for small and mid-sized farms, allowing those operations to remain viable and in turn, strengthening and growing rural communities.

Governor Vilsack has long been connected to the World Food Prize Foundation, having served on both the Council of Advisors and the Board of Directors. His insights and acumen were vital in shaping our mission and initiatives. His leadership and experience will be instrumental in expanding the Foundation’s international reach and continuing the mission of elevating innovations and inspiring action to sustainably increase the quality, quantity and availability of food for all.
