This site takes us into the world of structural biology -- a branch of molecular biology that focuses on the shape of nucleic acids and proteins (the molecules that do most of the work in our bodies). Learn about the structures and roles of proteins, tools used to study protein shapes, how proteins are used in designing new medications (for AIDS and arthritis), and what structural biology reveals about all life processes. Find out about careers in biomedical research.

Many people do not like spiders and consider them pests. However, spiders provide a service to humans. They eat many of the insects that bother people. In this 7th grade life science activity, students will study 4-6 spider webs and discover what and how much spiders eat. They will identify the spiders building the webs, collect data and make observations related to the webs and what the spiders eat. They will use the information to develop a conclusion.

What happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to explore the role of water.

Over the course of the unit, students will explore a variety of texts and grow in their knowledge of superbugs
and and their evolution over time. They will use informational text, video, lab activities and infographics to
support their inquiry and research.

These supplemental activities are intended to introduce students to classic and modern experiments in Cell Biology and Genetics. All of these activities are Open Educational Resources.

This course will introduce you to a general overview of the biological world. Important concepts will be reinforced and expanded upon through completion of weekly laboratory activities and homework assignments. Upon successful conclusion of the course, students will be able to do the following: Describe the nature of science, including its methods and its limitations; Describe the basic methodology of doing science and the scientific method; Use the scientific method to study everyday situations as well as in laboratory/field investigations; Identify, describe, and explain at a rudimentary level and present examples of, the characteristics common to all living things; Explain that living organisms are composed of molecules which interact in a variety of different chemical reactions necessary to sustain life; Explain that living organisms are comprised of one or more cells and are classified as prokaryotic or eukaryotic based on cellular characteristics; Describe the hereditary information possessed by living and explain how that information determines the cellular characteristics and functions (including basic Mendelian genetics); Explain and describe, with examples, the diversity of life, at different levels (basic molecular to ecological) and how it is hierarchically organized into systems; Explain how evolution by natural selection occurs, and describe the evidence that supports the theory of evolution; and more.

One of the biggest challenges scientists face when studying the ocean is observing the interplay between physical processes and biology in fine detail. Join Jules Jaffe, a research oceanographer in Scripps' Marine Physical Laboratory, as he describes his latest scheme to uncover these processes with swarms of inexpensive, miniaturized robotic floats that travel with currents, sense the environment and report their findings back to us.

Our brains are remarkably adaptable throughout our lives. Individual brain cells called neurons form synapses, sites of physical connection and communication between neurons, and then repeatedly rewire those connections in response to new experiences or to neuronal cell death caused by injury, disease, or aging. In this course, we will explore how neurons establish their synapses in the healthy brain during childhood and later in life, and how this process goes awry in disease states. More specifically, we will discuss how the brain forms its synapses early in life, stabilizes a subset of those synapses for long-term maintenance, and continues to add and remove synapses throughout life. We will then explore synapse dysfunction in diseases such as autism and Alzheimer’s disease, which involve abnormal increases or losses of synaptic connections, respectively. We will also consider synapse remodeling, a process of adding and removing synaptic connections to optimize our brain network, in the context of neuroinflammation, recovery from traumatic brain injury, and psychological trauma following prolonged stress.
This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. Many instructors of the Advanced Undergraduate Seminars are postdoctoral scientists with a strong interest in teaching.

This module discusses how taxonomic names for the genus and species categories are formed and standardized, and how the rules are bent when it comes to famous beasts, such as well known dinosaurs.

This is the first in a series of modules that introduce species taxonomy. This module introduces Carolus Linnaeus' work.

Students will observe the behavior of termites and draw conclusions about their behavior.

This textbook has evolved from online and live-in-person lectures presented in Professor Kenneth Todar's bacteriology courses at the University of Wisconsin-Madison. Its contents are suitable for reading or presentation in courses or course modules concerning general microbiology and medical bacteriology at the college and advanced high school levels of education. For teachers, instructional materials are available that accompany many chapters and topics. These include lecture outlines, notes, powerpoint presentations, and examination questions that compose a study guide

Biology is the study of life; however, there is more to it than this simple definition. In this seminar, you will be investigating the Unifying Principles of Biology. For example, changes and adaption of life are observed in nature. Regardless of the organism, those that are the best adapted will survive. This unifying principle and several others will be explored in this seminar.StandardsBIO.A.1.1 Describe the characteristics of life shared by all prokaryotic and eukaryotic organisms.

The goals of the Thermal Biology Institute's webpage are to present cutting-edge research focused on the biology of geothermal systems, to promote collaboration among researchers and resource agencies, and to advance public education on the biocomplexity of geothermal environments. Information is organized by topic including hot topics, research, current events, outreach, education, and electronic resources.

This investigation is a year round study of the phenology of a schoolyard.

An interview with biologist David Pearson, an author and expert on tiger beetles. Did you know that tiger beetles can run so fast that they go blind and just what would it be like to be hunted by these tiny, but ferocious animals? These are a few of the questions that we learn the answer from our guest biologist.

How is it that all cells in our body have the same genes, yet cells in different tissues express different genes? A basic notion in biology that most high school students fail to conceptualize is the fact that all cells in the animal or human body contain the same DNA, yet different cells in different tissues express, on the one hand, a set of common genes, and on the other, express another set of genes that vary depending on the type of tissue and the stage of development. In this video lesson, the student will be reminded that genes in a cell/tissue are expressed when certain conditions in the nucleus are met. Interestingly, the system utilized by the cell to ensure tissue specific gene expression is rather simple. Among other factors - all discussed fully in the lesson - the cells make use of a tiny scaffold known as the “Nuclear Matrix or Nucleo-Skeleton”. This video lesson spans 20 minutes and provides 5 exercises for students to work out in groups and in consultation with their classroom teacher. The entire duration of the video demonstration and exercises should take about 45-50 minutes, or equivalent to one classroom session. There are no supplies needed for students’ participation in the provided exercises. They will only need their notebooks and pens. However, the teacher may wish to emulate the demonstrations used in the video lesson by the presenter and in this case simple material can be used as those used in the video. These include play dough, pencils, rubber bands (to construct the nuclear matrix model), a tennis ball and 2-3 Meters worth of shoe laces. The students should be aware of basic information about DNA folding in the nucleus, DNA replication, gene transcription, translation and protein synthesis.

Paul Andersen takes you on a tour of the cell. He starts by explaining the difference between prokaryotic and eukaryotic cells. He also explains why cells are small but not infinitely small. He also explains how the organelles work together in a similar fashion.
