206 Frankenstein’s Cat Other Episodes About Animals Frankenstein's Cat This week, we’re looking at how biotechnology is super-charging the toolkit for customizing our pets, affecting the use of animals in medicine and livestock, and changing our relationship with the animal world. We’re joined by science write... Listen Bad Pharma This week, we’re taking a look at the questionable practices and suspect science employed by the companies that make our most widely used prescription drugs. The Altruism Equation This week. we’re looking at what science has to say about the origins of selfless – and even self-sacrificing – behavior. Weird Life This week, we’re learning about the search for strange and exotic lifeforms, in outer space, in overlooked corners on Earth, and even deep within our own tissues.

Hands-on Activities for Teaching Biology to High School or Middle School Students by Drs. Ingrid Waldron and Jennifer Doherty, University of Pennsylvania The expression "hands-on, minds-on" summarizes the philosophy we have incorporated in these activities - namely, that students will learn best if they are actively engaged and if their activities are closely linked to understanding important biological concepts. Many of our activities are explicitly aligned with the Next Generation Science Standards, as indicated by (NGSS) in the descriptions below and the links to the right. To accommodate limited budgets, most of our activities can be carried out with minimum equipment and expense for supplies. Additional resources for teaching biology are available at More Minds on Activities for Teaching Biology. Read More Intro and Biological Molecules Is Yeast Alive? Students evaluate whether the little brown grains of yeast obtained from the grocery store are alive by testing for metabolism and growth.

Forms of Energy Back to Table of Contents What are the different forms of energy? Energy has a number of different forms, all of which measure the ability of an object or system to do work on another object or system. In other words, there are different ways that an object or a system can possess energy. Here are the different basic forms: Kinetic Energy: Consider a baseball flying through the air. The formula for Kinetic energy, and for some of the other forms of energy described in this section will, is given in a later section of this primer. Potential Energy: Consider a book sitting on a table. Thermal, or heat energy: Consider a hot cup of coffee. Chemical Energy: Consider the ability of your body to do work. Electrical Energy All matter is made up of atoms, and atoms are made up of smaller particles, called protons (which have positive charge), neutrons (which have neutral charge), and electrons (which are negatively charged). Electrochemical Energy: Consider the energy stored in a battery. Sound Energy:
Study: Smell May Be Caused by Quantum Vibrations Could quantum physics explain the human sense of smell? A new study published in the Proceedings of the National Academy of Sciences (PNAS) lends credence to the theory that our sense of smell is based on sensing the vibrations caused by energy transfer at the subatomic level. The basis of the theory is that the structure of molecules is similar to that of balls held together by springs. This means the molecule can vibrate in a way unique to the composition of atoms in the molecule. When an electron hits a molecule, it loses quanta or discrete packets of energy. This would seem to fly in the face of the previous understanding of smell, which was based on the shape of the molecule — the so-called “lock and key” theory. Further studies using ‘nanowires’ have shown that this kind of molecular vibration can be observed and measured, opening the possibility for high-tech electronic noses.

How Much Energy is on my Plate? Contributed by Lane Seeley, Seattle Pacific University and Karin Kirk, SERC This activity addresses the Energy Awareness Principle by leading students through a sequence of activities that highlight the embodied energy that is necessary to produce various types of food. Context This activity can be used in many types of courses, from high school through college level. Goals After completing this activity students should be able to: complete simple calculations and unit conversions determine which source of protein requires the lowest energy input explain why different sources of food require different inputs of energy explain how variables like farming methods, processing methods and transportation can change the energy input of a given food. Activity Description Step 1. Have students watch the movie, keeping an eye out for more details about aspects on their concept sketches. Step 3. Along the way, each team should answer the following three questions: A. For example: Teaching Materials
Learning Center Alex, Here are some websites that I use for the Genetics Unit. As you've gotten some replies with this site already, I frequently do use the nClark WebSite which the link is below... However, I think some students know about this web site, so if you are planning on using the worksheets from here, you might want to make the assignment due in-class and don't assign them as take-home homework. Another website is the Biology Corner, which I beleive is owned by a teacher and used for his/her classroom. This website also has PowerPoints, labs, and simple activities that you can do with your students within the classroom. However, my favorite resource to go when I need to do Genetics activities is this link below. Many of the lesson plans, activities, labs, etc, are made professionally and very interactive.
Explore Biology | Labs | AP Biology Teaching & Learning Resources Welcome! Here you will find copies of most of the labs and activities that we perform in class. Some are only available from the AP Lab book, so I cannot post those online.
