Expression Vectors Used in Project-Oriented Teaching Laboratories Chapter 2
This chapter describes a multi-week project taught in an upper level cell and molecular biology laboratory. Isolation of sufficient quantities of rare proteins from biological tissues can be difficult. These native proteins are often required for raising antibodies, and for studying enzymatic or regulatory function. Expression vectors are used to obtain large quantities of proteins. The cDNA encoding a protein is cloned into an expression vector. The fusion protein is over-expressed in E. coli,
Physicians can easily tell if you are a smoker by how your lungs look. Normal lungs are red or pink and fluid-looking. Smokers have blackened lungs that are drier than normal lungs. Tumors may develop from continued tobacco use-these appear as white masses.

Atoms: Protons, Neutrons, and Electrons - by StudyJams
An atom is a tiny particle in matter, and atoms are made of protons, neutrons, and electrons. Some matter, like your body or your book, is made of lots of different kinds of atoms, but elements are made up of only one kind of atom. Learn more about atoms with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.
Our Solar System: Outer Planets - by StudyJams
Jupiter, Saturn, Uranus, and Neptune are all of the outer planets in our solar system. There is a planetoid called Pluto out there too! Learn more about our outer planets with this slide show from StudyJams. Vibrant images are set to music while information is written under each photo. A short, self-checking quiz is also included with this link.
Students learn about the advantages and disadvantages of the greenhouse effect. They construct their own miniature greenhouses and explore how their designs take advantage of heat transfer processes to create controlled environments. They record and graph measurements, comparing the greenhouse indoor and outdoor temperatures over time. Students are also introduced to global issues such as greenhouse gas emissions and their relationship to global warming.
Build an Approximate Scale Model of an Object
Students will create a model of an object of their choice, giving them skills and practice in techniques used by professionals. The students will use sketches as they build their objects. This activity will facilitate a discussion on models and their usefulness.
Melting Glaciers: Clues to Climate Change
This interactive feature story is part of Science Bulletins, an innovative online and exhibition program that offers the public a window into the excitement of scientific discovery. Published in March 2005, this Earth Bulletin follows a team of glaciologists racing to core the world's largest tropical ice cap -- before global warming melts it away.
