Resources to mark the 100th day of school with math activities. Challenge students to generate 100 different ways to represent the number 100. Students will easily generate 99 + 1 and 50 + 50, but encourage them to think out of the box. Challenge them to include examples from all of the NCTM Standards strands: number sense, numerical operations, geometry, measurement, algebra, patterns, data analysis, probability, discrete math, Create a class list to record the best entries. Some teachers write 100 in big bubble numeral style and then record the entries inside the numerals.

The goal of this lesson is to introduce students who are interested in human biology and biochemistry to the subtleties of energy metabolism (typically not presented in standard biology and biochemistry textbooks) through the lens of ATP as the primary energy currency of the cell. Avoiding the details of the major pathways of energy production (such as glycolysis, the citric acid cycle, and oxidative phosphorylation), this lesson is focused exclusively on ATP, which is truly the fuel of life. Starting with the discovery and history of ATP, this lesson will walk the students through 8 segments (outlined below) interspersed by 7 in-class challenge questions and activities, to the final step of ATP production by the ATP synthase, an amazing molecular machine. A basic understanding of the components and subcellular organization (e.g. organelles, membranes, etc.) and chemical foundation (e.g. biomolecules, chemical equilibrium, biochemical energetics, etc.) of a eukaryotic cell is a desired prerequisite, but it is not a must. Through interactive in-class activities, this lesson is designed to spark the students’ interest in biochemistry and human biology as a whole, but could serve as an introductory lesson to teaching advanced concepts of metabolism and bioenergetics in high school depending on the local science curriculum. No supplies or materials are needed.

Is climate change real? Yes, it is! And technologies to reduce Greenhouse Gas (GHG) emissions are being developed. One type of technology that is imperative in the short run is biofuels; however, biofuels must meet specifications for gasoline, diesel, and jet fuel, or catastrophic damage could occur. This course will examine the chemistry of technologies of bio-based sources for power generation and transportation fuels. We'll consider various biomasses that can be utilized for fuel generation, understand the processes necessary for biomass processing, explore biorefining, and analyze how biofuels can be used in current fuel infrastructure.

We are happy to welcome you to our second Open Educational Resource (OER) textbook, Biochemistry Free For All. Biochemistry is a relatively young science, but its rate of growth has been truly impressive. The rapid pace of discoveries, which shows no sign of slowing, is reflected in the steady increase in the size of biochemistry textbooks. Growing faster than the size of biochemistry books have been the skyrocketing costs of higher education and the even faster rising costs of college textbooks. These unfortunate realities have created a situation where the costs of going to college are beyond the means of increasing numbers of students.

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.

Life is all around us, both as multicellular organisms such as the iguana and bamboo above, as well as the unicellular microorganisms such as bacteria.  Life is present on every continent, in the air and in the waters of the world.  There is life even in the Mariana Trench, seven miles below the surface of the ocean.  As of 2010 biologists have described and classified 1.7 million plants and animals, and estimate that there are till over five million species still undiscovered.This chapter will introduce the ways we study the science of Biology in the twenty-first century, the characteristics of living organisms and their classification.

Living things are highly organized and structured, following a hierarchy that can be examined on a scale from small to large. The atom is the smallest and most fundamental unit of matter. It consists of a nucleus surrounded by electrons. Atoms form molecules. A molecule is a chemical structure consisting of at least two atoms held together by one or more chemical bonds. Many molecules that are biologically important are macromolecules, large molecules that are typically formed by polymerization (a polymer is a large molecule that is made by combining smaller units called monomers, which are simpler than macromolecules). An example of a macromolecule is deoxyribonucleic acid (DNA) (Figure 1.15), which contains the instructions for the structure and functioning of all living organisms.

If the dialysis is the most know method used for buffer exchange, other methods less as desalting and tangential flow filtrations can be useful to speed up or scale up the buffer exchange process.

The assignment pre-tests student understanding of the CCD, lysocline, calcareous ooze, and the deposition of marine sediments near mid-ocean ridges and ocean basins.

Cell Biology, Genetics, and Biochemistry for Pre-Clinical Students (2021) is an undergraduate medical-level resource for foundational knowledge across the disciplines of genetics, cell biology and biochemistry. This USMLE-aligned text is designed for a first-year undergraduate medical course that is delivered typically before students start to explore systems physiology and pathophysiology. The text is meant to provide the essential information from these content areas in a concise format that would allow learner preparation to engage in an active classroom. Clinical correlates and additional application of content is intended to be provided in the classroom experience. The text assumes that the students will have completed medical school prerequisites (including the MCAT) in which they will have been introduced to the most fundamental concepts of biology and chemistry that are essential to understand the content presented here. This resource should be assistive to the learner later in medical school and for exam preparation given the material is presented in a succinct manner, with a focus on high-yield concepts.

The 276-page text was created specifically for use by pre-clinical students at Virginia Tech Carilion School of Medicine and was based on faculty experience and peer review to guide development and hone important topics.

About the Author
Renée J. LeClair is an Associate Professor in the Department of Basic Science Education at the Virginia Tech Carilion School of Medicine, where her role is to engage activities that support the departmental mission of developing an integrated medical experience using evidence-based delivery grounded in the science of learning. She received a Ph.D. at Rice University and completed a postdoctoral fellowship at the Maine Medical Center Research Institute in vascular biology. She became involved in medical education, curricular renovation, and implementation of innovative teaching methods during her first faculty appointment, at the University of New England, College of Osteopathic Medicine.

Enzymes are biocatalyst they accelerate the chemical reaction. They are organic, all enzymes are made of protein but not all enzymes are protein. Certain biological reactions can be catalyzed by RNA called Ribozyme. Protein is a dynamic molecule; its activity depends on the three-dimensional structure. For example, the water droplet size gets flexible, if you touch. Protein folding and three-dimensional structures are vital for activity.  There is no living cell without an enzyme, in the living cell; it functions to accelerate the biological reaction. There is a misfolded protein infectious agent called Prion, which causes normal brain protein to misfold which, leads to neurodegratative disease. This module presents concise notes of enzyme basic concepts; bioinformatics tools and few examples of enzymes in everyday life.
