This video addresses acidification of the ocean and the ecological and economic implications of the resulting pH change on marine life. It includes information about how ocean acidification resulting from increased absorption of CO2 from the atmosphere is affecting ocean species such as sea urchins and oysters. Scientists from the University of California at Santa Barbara discuss their experiments with sea creatures in acidic sea water. There is an associated lesson plan and classroom activity that has students test the effects of CO2 on water pH.

Spreadsheets Across the Curriculum module. Students build spreadsheets to explore conditions that lead to chaotic behavior in logistic models of populations that grow discretely.

This guided note packet was created for my online Fundamentals of Biology students at West Hills College Lemoore.

This is a powerpoint presentation of the contents found within chapter 5 of the openstax biology textbook.

This outline was created as a lecture outline for my online Fundamentals of Biology course to accompany Concepts of Biology by Open Stax.

This is the second in a series of modules which detail the research of Charles Darwin and evolutionary theory. This module continues with a discussion of the processes that led to Darwin's formulation of the theory of natural selection.

This module introduces Darwin's Galapagos travels and an introduction to the theory of evolution as a force for biological change and diversification. This is the first in a series of modules which detail the research of Charles Darwin and evolutionary theory.

This kit is a historical overview of American representations of chemicals from the three sisters to the Love Canal. It compares conflicting constructions about nuclear reactor safety, depleted uranium, Rachel Carson and DDT. Through analyzing diverse historic and contemporary media messages, students understand changing public knowledge, impressions and attitudes about chemicals in the environment.

Short Description:
This book aims to provide the basic foundational chemistry required to understand the structure and function of human cells, tissues, organs, and organ systems covered in Biology 1190 and 1191 at Langara College.

In this seminar you will use images to differentiate the structure of a chloroplast and mitochondria. You will follow an animation to learn about the two essential processes that take place in each cell organelle to accurately determine the importance of structure and function. You will also analyze data from mice to determine the effects of exercise and performance enhancing drugs on the presence of mitochondria in a cell, or extract chlorophyll from various levels to examine its function outside a chloroplast.StandardsBIO.A.3.1.1 Describe the fundamental roles of plastids (e.g., chloroplasts) and mitochondria in energy transformations.BIO.A.3.2.1 Compare and contrast the basic transformation of energy during photosynthesis and cellular respiration.BIO.A.3.2.2 Describe the role of ATP in biochemical reactions

Students will use books, encyclopedias, magazines, and the Internet to discover certain facts about an insect of their choice.

Students use EOL Species Cards to sort and make observations of animals, then use the RAFT writing strategy to create short presentations about the characteristics of each major group of animals.

Students apply their understanding of physical characteristics and biological classification of different organisms through a game of classification "Go Fish!"

The topic of this video module is how to classify animals based on how closely related they are. The main learning objective is that students will learn how to make phylogenetic trees based on both physical characteristics and on DNA sequence. Students will also learn why the objective and quantitative nature of DNA sequencing is preferable when it come to classifying animals based on how closely related they are. Knowledge prerequisites to this lesson include that students have some understanding of what DNA is and that they have a familiarity with the base-pairing rules and with writing a DNA sequence.

This activity is a field investigation where students gather leaves from various trees on school property, interpret findings, name tree and leaves, journal activity and develop a new "aha" for nature!

This activity is a classroom and schoolyard investigation where students collect daily temperature and precipitation readings, weather observations, and weekly phenology reports in a phenology binder and in nature journals. Students then analyze this data and compare to recorded values in the Weatherguide calendar.

Students investigate decomposers and the role of decomposers in maintaining the flow of nutrients in an environment. Students also learn how engineers use decomposers to help clean up wastes in a process known as bioremediation. This lesson concludes a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

If you'd visited Tuolumne Meadows in Yosemite National Park 100 years ago, you probably would have encountered the alpine chipmunk, Tamias alpinus. Today, however, park visitors will have to hike up a nearby mountain to see one of these critters. That's because this species is sensitive to temperature and over the last hundred years of global climate change, Yosemite has warmed by about 5.5 degrees Fahrenheit. As the temperature increased, the chipmunks retreated to higher and higher elevations where it was cooler. Today, they occupy a fraction of their original range. If climate change continues, they could be squeezed right off the tops of their mountains and out of existence.
