As the carbon dioxide concentration of our atmosphere increases and our climate warms, the hay fever season seems to be getting longer and more severe. In this case study, students assume the a role of a public relations specialist contracted to communicate the link between climate change and pollen allergies. The activity focuses on the importance of scientific skills to careers outside science, and is most suitable for a lower-level introductory biology, human health, or environmental science course.
The study of biomimicry and sustainable design promises great benefits in design applications, offering cost-effective, resourceful, non-polluting avenues for new enterprise. An important final caveat for students to understand is that once copied, species are not expendable. Biomimicry is intended to help people by identifying natural functions from which to pattern human-driven services. Biomimicry was never intended to replace species. Ecosystems remain in critical need of ongoing protection and biodiversity must be preserved for the overall health of the planet. This activity addresses the negative ramifications of species decline. For example, pollinators such as bees are a vital work force in agriculture. They perform an irreplaceable task in ensuring the harvest of most fruit and vegetable crops. In the face of the unexplained colony collapse disorder, we are only now beginning to understand how invaluable these insects are in keeping food costs down and even making the existence of these foods possible for humans.
Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
By the end of this section, you will be able to:Explain why angiosperms are the dominant form of plant life in most terrestrial ecosystemsDescribe the main parts of a flower and their purposeDetail the life cycle of an angiospermDiscuss the two main groups of flowering plants
By the end of this section, you will be able to:Explain when seed plants first appeared and when gymnosperms became the dominant plant groupDescribe the two major innovations that allowed seed plants to reproduce in the absence of waterDiscuss the purpose of pollen grains and seedsDescribe the significance of angiosperms bearing both flowers and fruit
This online article, from Biodiversity Counts, offers insight into how plants interact with arthropods. It has: an explanation of the difference between detrimental and mutually beneficial relationships; some of the chemical and mechanical modifications plants have made to attract helpful arthropods and fend off harmful ones; a detailed overview of pollination, with descriptions of seven common pollination syndromes; a detailed overview of plant defense mechanisms; and a series of questions students can ask when they see an arthropod on a plant in order to learn more about how the two are interacting.
The goals of the International OER Exchange Pilot project are to: facilitate the development and use of Open Educational Resources (OER) by teachers and students globally, track the development and use of the science learning materials and data collection, especially around climate change study, created in the project through OER Commons, and highlight the process and results through workshops and conference presentations.The broader purpose of the project is to support the international exchange of information and understanding through freely available resources among teachers and students, especially in the area of environmental science and climate change investigation.
This course will help meteorologists and others broaden their understanding of the impacts of weather and climate on public health, including the impacts of heat waves and cold temperatures, winter storms and thunderstorms, flooding, drought, poor air quality, tornadoes, hurricanes, wildfire, UV radiation, and others. This course is directed to broadcast meteorologists, in particular, who play a critical role in the community by helping the public to protect against weather-related health threats and by promoting good health. The course also describes the public health communication system, providing information about reliable public health services, tools, and resources.
Students are introduced to the concepts of air pollution and air quality. The three lesson parts focus on the prerequisites for understanding air pollution. First, students use M&Ms to create a pie graph that expresses their understanding of the composition of air. Next, students watch and conduct several simple experiments to develop an understanding of the properties of air (it has mass, it takes up space, it can move, it exerts pressure, it can do work). Finally, students develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper. In an associated literacy activity, students explore the environmental history timeline.
