Hold It
In this outdoor activity/field trip, learners investigate the special shapes, holding structures and holding behaviors that real organisms use in streams, rivers, creeks or coast intertidal zones to avoid being swept away by moving water. Learners then create their own "animal" with holding adaptations. The activity includes drawings that detail helpful equipment such as bug boxes and dip nets, as well as instructions for making a milk-carton observation tray and flow-through trough.

Dr. Chin-Feng Hwang: Academic Spotlight
Dr. Chin-Feng Hwang, associate professor in the William H. Darr School of Agriculture, was recently awarded funding to participate in a Specialty Crop Research Initiative project. The goal of this project is to accelerate improvement of various grape plants by working at the molecular level of the plants. The work is known as "molecular marking" and "molecular breeding." The work will ultimately assist in the breeding of the Norton grape, which is the official grape of the state of Missouri.

7.2 Is the equilibrium position unfavourable?

The first possibility is that the reaction system has been able to reach chemical equilibrium, but the equilibrium position is not favourable. How does this come about? If equilibrium has been reached, then the forward (left to right) and backward (right to left) reactions are occurring at equal rates. In such a case, we can emphasise the fact by writing the reaction with two opposed, half-headed arrows:

4.6 Summary of Section 4

  1. The chemical formulae of many substances can be understood by arguing that their atoms attain noble gas structures by chemical combination.

  2. In ionic compounds, this is achieved by the transfer of electrons from one atom to another; in molecular substances, it happens through the sharing of electron pairs in covalent bonds. But in both cases, bonds between atoms consist of shared pairs of electrons. In covalent compounds the sharing is fairl

1.4.1 Bearings

In the following subsections, we apply the vector ideas introduced so far to displacements and velocities. The examples will feature directions referred to points of the compass, known as bearings.

The direction of Leeds relative to Bristol can be described as ‘15° to the East of due North’, or N 15° E. This is an instance of a bearing. Directions on the ground are typically given like this, in terms of the directions North (N), South (S), East (E)

1.6 Do, talk and record triad

The do–talk–record triad (DTR) is a description of what is likely to take place in collaborative mathematics classrooms. It is concerned with observable events, and with the learner rather than the teacher, though many teaching insights flow from it. Although the order of the triad suggests that it should be followed in a particular sequence, this is not necessarily the case. Sometimes talking comes before doing or recording before talking. It also takes time for a learner to move
