Students learn about the practical uses, structure, mathematics and terminology of the binary number system. They learn how to convert a given number from the binary to the decimal number system and vice versa, and perform binary addition and subtraction as part of a class game. They use this understanding to build their own simple, mechanical "hard drive" a box that uses binary numbers to represent words for later retrieval. The activity helps students build an appreciation for the way that computers and electronics store and retrieve information.

In the exploration of ways to use solar energy, students investigate the thermal energy storage capacities of different test materials to determine which to use in passive solar building design.

This unit looks at the methods that have been developed by organisms for the uptake, transport and storage of iron: a process made more complicated by the insolubility of its oxides and hydroxides. You will examine iron storage in mammals, including humans, is achieved by ferritin, which stores iron as a hydrated iron (III) oxide - an example of biomineralisation.
Teaches principles of experimental methods in human perception and cognition, including design and statistical analysis. Combines lectures and hands-on experimental exercises; requires an independent experimental project. Some experience in programming desirable. To foster improved writing and presentation skills in conducting and critiquing research in cognitive science, students are required to provide reports and give oral presentations of three team experiments; a fourth individually conducted experiment includes a proposal with revision, and concluding written and oral reports.
Seminar in real-time language comprehension. Models of sentence and discourse comprehension from the linguistic, psychology, and artificial intelligence literature, including symbolic and connectionist models. Ambiguity resolution. Linguistic complexity. The use of lexical, syntactic, semantic, pragmatic, contextual and prosodic information in language comprehension. The relationship between the computational resources available in working memory and the language processing mechanism. The psychological reality of linguistic representations.
Principles of operation, algorithms, applications, and limitations of optical detection, storage, processing, transmission and display devices and systems. Topics: review of basic properties of electromagnetic waves; holography; spatial light modulator and display devices; thermal and quantum photodetectors; optical storage media such as disks and 3-D holographic materials; fiberoptic communication systems; optical interconnection device technologies; coherent and incoherent light processors based on Fourier optics, Acousto-optics, and optoelectronic neural networks; role of optics in next-generation computers; applications to image processing, pattern recognition, radar systems and adaptive optics; limitations of optical processors.
This is a simple activity to visualize a communication system. In order to do this the students encode, decode, transmit, receive and store messages. They will use a code sheet and flashlight for this process. They will also maintain a storage sheet from which they can retrieve information as and when it is required.
