How Many Drops?
In this lesson and its associated activity, students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. The three liquids are water, rubbing alcohol, and vegetable oil; because of their different surface tensions, more water can be piled on top of a penny than either of the other two liquids. However, this is not the main point of the activity. Instead, students are asked to come up with an explanation for their observations

Life on the Moon
In this lesson, students learn about the physical properties of the Moon. They compare these to the properties of the Earth to determine how life would be different for astronauts living on the Moon. Using their understanding of these differences, they are asked to think about what types of products engineers would need to design for us to live comfortably on the Moon.

Activity 4: What do you see?
We know that culture guides the way people behave in society as a whole. But culture also plays a key role in organisations, which have their own unique set of values, beliefs and ways of doing business. This unit explores the concepts of national and organisational culture and the factors that influence both.

We seem to have come a long way and covered a great deal of ground since I approached this subject by explaining that a mechanism must exist to help us focus on one sound out of many. That clearly is one function of attention, but attention seems to have other functions too. The results of visual search experiments show that attention is a vital factor in joining together the features that make up an object, and the experiences of brain-damaged patients suggest that this feature-assembly role

3.3 Non-target effects

Treisman's feature integration theory has been very influential, but it does not appear to explain all experimental observations, and there have been alternative accounts of the feature-binding process. Duncan and Humphreys (1989) reported effects which do not fit too well within the basic Treisman account. They required participants to search for the letter ‘L’ (the target) within a number of ‘Ts’ (the non-targets). You may get a feel for the relative difficulty of d

Some Dinosaur Groups Diminishing Before Mass Extinction: Live Chat with Museum Scientists
