2.2 Knowing about unseen information An obvious difference between hearing and seeing is that the former is extended in time, while the latter extends over space. So, for example, we can listen to a spoken sentence coming from one place, but it takes some time to hear it all. In contrast, a written sentence is spread over an area (of paper, say) but, as long as it is reasonably short, it can be seen almost instantly. Nevertheless, seeing does require some finite time to capture and analyse the information. This process can be ex
1.3 Attending to sounds From the earlier sections, you will appreciate that the auditory system is able to separate different, superimposed sounds on the basis of their different source directions. This makes it possible to attend to any one sound without confusion, and we have the sensation of moving our ‘listening attention’ to focus on the desired sound. For example, as I write this I can listen to the quiet hum of the computer in front of me, or swing my attention to the bird song outside the window to

Do You Have the Strength?
In this activity, students squeeze a tennis ball to demonstrate the strength of the human heart. Working in teams, they think of ways to keep the heart beating if the natural mechanism were to fail. The goal of this activity is to get students to understand the strength and resilience of the heart.
Tinnitus
This patient education program explains tinnitus and provides tips for coping with its symptoms. It also reviews the anatomy of the ear and hearing, causes, symptoms, diagnosis, and treatment options for tinnitus. This resource is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.
Nuts and Bolts
In this activity, an array of nuts and bolts, of distinctly different sizes, are lined up on the table. The child first matches the nut to the bolt, then screws the nut on.
Heart Healthy Living
This three minute video is about keeping your heart healthy by simple diets and exercises. Having high cholesterol blocks artery making it narrower and narrower. As it gets smaller and smaller, it can lead to a heart attack. LDL is what builds up plaque in the cholesterol and HDL is what removes the plaque. If you want to avoid high cholesterol, it is best to eat many healthy foods every day and stay away from any foods that may contain trans fat. For exercisin
Unit 2 - Linking household food security with nutrition and livelihoods
This unit we focus on household food security and what the effect of food insecurity will be on households. These days the concepts nutrition, nutrition security, livelihoods and household livelihood security are also used when the bigger picture of household food security is discussed.
Household Food Security: Module 1: Introduction to Household Food Security
In this module we will introduce you to concepts such as food security, food insecurity, nutrition security, livelihood security, food policies and programmes and the role of stakeholders and facilitators. You will gain the knowledge and skills required to gather information on many different levels, from the macro to the micro level. You will also, in time, become equipped to analyse community and household needs, understand the implications of policies and strategies for communities and househ
Household Food Security Programme Description
This study guide for the module PHFS01K Introduction to Household Food Security is the first of six modules in the programme to be piloted with a group of volunteers linked to non-governmental organisations (NGOs) in the Eastern Cape. The Eastern Cape Non-governmental Organisation Coalition (ECNGOC) has supported the strategy through advocacy and helping to link organisations with the project, thus enabling the recruitment of practising volunteers or community development workers who want to be
Allometry in Biological Systems
This is a laboratory exercise appropriate for sophomore level students. No prior math is required, and lab exercise can be adapted if computer facilities are available.
Portable Sundial
Students investigate the accuracy of sundials and the discrepancy that lies between "real time" and "clock time." They track the position of the sun during the course of a relatively short period of time as they make a shadow plot, a horizontal sundial, and a diptych sundial. (The activity may be abridged to include only one or two of the different sundials, instead of all three.)

Terrible math lessons Hollywood is teaching our kids The two videos below take a look at the gross mathematical errors that are found in some of our biggest Hollywood Blockbusters. They might prove as a great starting point to a lesson by watching some of the sequences and then working through them as a class just to highlight how inaccurate some of these are.
