In an interview, a zookeeper at the Columbus, Ohio, polar bear exhibit describes time she spent at Churchill, Manitoba, educating tourists about polar bears and what can be done to help populations in the wild. This interview appeared in the free, online magazine Beyond Penguins and Polar Bears.

Meiosis is the process by which gametes (eggs and sperm) are made. Gametes have only one set of chromosomes. Therefore, meiosis involves a reduction in the amount of genetic material. Each gamete has only half the chromosomes of the original germ cell. Explore meiosis with a computer model of dragons. Run meiosis, inspect the chromosomes, then choose gametes to fertilize. Predict the results of the dragon offspring and try to make a dragon without legs. Learn why all siblings do not look alike.

A one page assignment that uses online tutorials to give students a first exposure to the components of a cell and membrane.

All animals develop and grow over time. The animals in this video segment, however, undergo very dramatic changes on their way to adulthood -- a developmental process known as metamorphosis.

Students explore the relationships between genetics, biodiversity, and evolution through a simple activity involving hypothetical wild mouse populations. First, students toss coins to determine what traits a set of mouse parents possesses, such as fur color, body size, heat tolerance, and running speed. Next they use coin tossing to determine the traits a mouse pup born to these parents possesses. These physical features are then compared to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?

This group learning activity involves students in an engaging review of concepts of microbiology. The review is set up as a power point presentation in the style of the "Jeopardy" gameshow where students groups compete against each other to answer review questions.

Students obtain a basic understanding of microfluidic devices, how they are developed and their uses in the medical field. After conducting the associated activity, they watch a video clip and learn about flow rate and how this relates to the speed at which medicine takes effect in the body. What they learn contributes to their ongoing objective to answer the challenge question presented in lesson 1 of this unit. They conclude by solving flow rate problems provided on a worksheet.

Students learn about the form and function of the human heart through the dissection of sheep hearts. They learn about the different parts of the heart and are able to identify the anatomical structures and compare them to the all of the structural components of the human heart they learned about in the associated lesson, Heart to Heart.

This video segment from NOVA: "The Mystery of Animal Pathfinders" explores the migratorial exploits of monarch butterflies.

Students will learn about Wyoming's pronghorn population and the challenges it faces from human activity.

Spreadsheets Across the Curriculum module. Students use Excel Solver to find the linear combination of servings of two specified foods that minimize cost while meeting nutritional requirements.

The activity is a field trip to Minnehaha Falls where students will observe and record their findings in a science notebook.

This activity is a classroom guided inquiry lesson where the student will sort, identify, and classify Minnesota fish.

This activity is a classroom and field investigation where students will group Minnsota fish families and create their own pop can fishing rods.

This video segment, adapted from NOVA scienceNOW, introduces the latest research on a system of neurons that plays a part in how people relate to each other.

In this video segment adapted from Hope in a Changing Climate, learn how an environmentally devastated ecosystem has been restored, benefiting both the local economy and global efforts to fight climate change.

Drawings and animations, are used to help participants understand the differences between and steps involved in mitosis and meiosis. The cell cycle as well as individual steps of mitosis and meiosis are included in this learning material.

Spreadsheets across the Curriculum Module. Students use Excel to conduct data analysis and examine bacteria growth in a lake.

This initial module from the GENIQUEST project introduces the dragons and the inheritance of their traits, then delves into meiosis and its relationship to inherited traits. Students examine the effects of choosing different gametes on dragon offspring, and learn about genetic recombination by creating recombination events to generate specific offspring from two given parent dragons. Students learn about inbred strains and breed an inbred strain of dragons themselves.

In this activity, students interact with 12 models to observe emergent phenomena as molecules assemble themselves. Investigate the factors that are important to self-assembly, including shape and polarity. Try to assemble a monolayer by "pushing" the molecules to the substrate (it's not easy!). Rotate complex molecules to view their structure. Finally, create your own nanostructures by selecting molecules, adding charges to them, and observing the results of self-assembly.
