1.2 Taxa and relationships

Until the mid-20th century, inferences about evolutionary relationships between species were generally based upon as wide a range of evidence as could be mustered. Evolutionary systematics is the name given to this eclectic approach, because of its explicit focus on evolutionary conclusions. The disparate nature of the evidence used (ranging from the taxonomic attributes and geographical distribution of living organisms to the stratigraphical distribution of fossils) meant that there w

Where Do You Get Your Energy?
Cells extract energy from sugar to produce ATP, the molecular fuel that powers all life processes. This interactive activity adapted from Exploratorium delves into the processes that enable cells to unlock the energy contained in the foods we consume. We often use the term "energy" as an informal shorthand for our ability to stay alert and complete tasks. In fact, the presence of energy-rich molecules and our cells' ability to obtain, process, and

The Role of Blogging in Open Notebook Science
I spoke at the North Carolina Science Blogging Conference (un-conference really) on January 19, 2008. Mainly I reviewed some of my posts on the UsefulChem blog from the past few months to show what types of issues are relevant to doing research openly. I then showed the connection from the blog to the wiki, mailing list and GoogleDocs where the laboratory data get reported and analyzed

2.000 How and Why Machines Work (MIT)
Subject studies how and why machines work, how they are conceived, how they are developed (drawn), and how they are utilized. Students learn from the hands-on experiences of taking things apart mentally and physically, drawing (sketching, 3D CAD) what they envision and observe, taking occasional field trips, and completing an individual term project (concept, creation, and presentation). Emphasis on understanding the physics and history of machines.

4.1 Trilobites

As we've seen, the Cambrian explosion left the seas teeming with a huge variety of animals. In the following activity you will study some of the marine life at one particular time in the Palaeozoic Era - the middle part of the Silurian Period, 430 Ma ago. You'll look in detail at some fossils which come from a deposit in the UK called the Wenlock Limestone, famous for its many beautiful fossils. The Wenlock Limestone crops out mainly around Birmingham and the borders of Wales.
