In this activity, students examine how different balls react when colliding with different surfaces. Also, they will have plenty of opportunity to learn how to calculate momentum and understand the principle of conservation of momentum.

Students become product engineers in a bouncy ball factory as they design and prototype a polymer bouncy ball that meets specific requirements: must be spherical in shape, cannot disintegrate when thrown on the ground, and, of course, must bounce. Along with these design elements, students can build (with teacher assistance) a “shadow box” that helps measure the contact angle of the polymer that provides data on how to iterate. In addition, students must consider the aesthetics of their bouncy balls for customer approval and marketing purposes. Using the engineering design process, students design and create bouncy balls from polymers to create a fun, exciting toy for children.

This is a study guide to accompany an introductory university level Biology course.

Microbiology is a broad term which includes virology, mycology, parasitology, bacteriology, immunology, and other branches. A microbiologist is a specialist in microbiology and these related topics. Microbiological procedures usually must be aseptic and use a variety of tools such as light microscopes with a combination of stains and dyes. As microbes are absolutely required for most facets of human life.

Students investigate whether a bowling ball will float or sink in an aquarium of water after measuring the ball and determining the density. This is meant to be an investigative inquiry of the concepts of density and significant figures.

Students find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box from the original box material, students discover that the cubical box has less surface area than the original, and thus, a cube is a more efficient way to package things. Students then consider why consumer goods generally aren't packaged in cube-shaped boxes, even though they would require less material to produce and ultimately, less waste to discard. To display their findings, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved. The activities involved provide valuable experience in problem solving with spatial-visual relationships.

To display the results from the previous activity, each student designs and constructs a mobile that contains a duplicate of his or her original box, the new cube-shaped box of the same volume, the scraps that are left over from the original box, and pertinent calculations of the volumes and surface areas involved. They problem solve and apply their understanding of see-saws and lever systems to create balanced mobiles.

Watch water boil at room temperature. The temperature at which water boils depends on pressure. You can demonstrate this by dramatically lowering the pressure on a water-filled plastic syringe at room temperature.

This is an activity where students watch what happens to marshmallows under pressure and relate it to Boyle's law.

Students are taught how to use FossilPlot software in the lab prior to this exercise. Students work individual to work through the short exercise, handing in a copy of the diversity graphs for the brachiopod orders (which will be tested in the following midterm) and a completed worksheet. The exercise reinforces the main functions of FossilPlot and addresses basic concepts on diversity and biostratigraphy. Once the assignments are collected and graded, we discuss the outcomes of the exercise in class.

Building on lessons learned over several summers, Kristin Raab—Health Impact Assessment and Climate Change Program Director in the Environmental Health Division of Minnesota’s Department of Health—packaged information from diverse communities into a cohesive toolkit that communities of all sizes can use to prepare for heat waves. The Minnesota Extreme Heat Toolkit describes changing weather conditions in Minnesota, the magnitude of potential health consequences from extreme heat, and key steps communities can take to prevent heat-related illnesses and deaths. The toolkit acknowledges that extreme heat response plans will vary with the size of the community and the habits of its residents: examples from the mostly rural Olmsted County and the urban centers of Saint Paul and Minneapolis illustrate a range of community plans that could be useful in Minnesota and beyond.

Students learn about the similarities between the human brain and its engineering counterpart, the computer. Since students work with computers routinely, this comparison strengthens their understanding of both how the brain works and how it parallels that of a computer. Students are also introduced to the "stimulus-sensor-coordinator-effector-response" framework for understanding human and robot actions.

The trifecta of globalization, urbanization and digitization have created new opportunities and challenges across our nation, cities, boroughs and urban centers. Cities are in a unique position at the center of commerce and technology becoming hubs for innovation and practical application of emerging technology. In this rapidly changing 24/7 digitized world, city governments worldwide are leveraging innovation and technology to become more effective, efficient, transparent and to be able to better plan for and anticipate the needs of its citizens, businesses and community organizations. This class will provide the framework for how cities and communities can become smarter and more accessible with technology and more connected.

Students learn about stress and strain by designing and building beams using polymer clay. They compete to find the best beam strength to beam weight ratio, and learn about the trade-offs engineers make when designing a structure.
