Adventures through the Plant Kingdom

Liz Mahood, Clarice Guan, and Heather Phillips: Plant Science, Cornell University

Have you ever wanted to become an adventurer? In this virtual tour, you can join us as we explore the jungle found right at Cornell! We’ll explore the many different types of plants found there, and highlight the exciting, exotic, and important plants. You will see plants that make pretty flowers, a plant that doesn’t make roots, stems, or leaves, plants that make medicine, and plants that move! We will also learn how people study plants and learn about what it’s like to be a plant scientist

The Digestive Physiology of Cows

Amanda Davis: Animal Science, Cornell University

Have you ever wondered why cows can digest grass, but humans can’t? This video shows how the microorganisms in a cow’s rumen help a cow break down grass into nutrients that she needs to make milk. In this demo, you will get to see a rumen sample taken from Cornell’s cannulated cow, Sunny, and you will have the chance to view her rumen microorganisms under the microscope.
