Build an Approximate Scale Model of an Object
Students will create a model of an object of their choice, giving them skills and practice in techniques used by professionals. The students will use sketches as they build their objects. This activity will facilitate a discussion on models and their usefulness.
Does Your Chewing Gum Lose Its Flavor?
In the first part of the activity, each student chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days before weighing it to determine the amount of mass lost. This mass corresponds to the amount of sugar in the gum, and can be compared to the amount stated on the package label. In the second part of the activity, students work in groups of four to design and conduct new experiments based on questions of their own choosing. These questions arise naturally
Heave Ho!
Students will discover the scientific basis for the use of inclined planes. They will explore, using a spring scale, a bag of rocks and an inclined plane, how dragging objects up a slope is easier than lifting them straight up into the air. Also, students are introduced to the scientific method and basic principles of experimentation. Finally, students design their own use for an inclined plane.
Construct And Test Roofs for Different Climates
We design and create objects to make our lives easier and more comfortable. The houses in which we live are an excellent example of this. Depending on your local climate, the features of your house will be different to satisfy your particular needs; protection from hot, cold, windy, and/or rainy weather. Students should be aware of the different types of roofs found on various houses in different environments throughout the world. This can be done with books and photos. Models of the houses will
Introduction In this unit we explore the way in which older age has been socially constructed, and focus particularly on how the identity of being an ‘old age pensioner’ (OAP) developed during the twentieth century. This unit is an adapted extract from the course Personal lives and social policy (DD305) Original Copyright © 2004 The Open 3.6 Population policy The period of fertility decline in Britain coincided with a time when anxieties about population control came to dominate a wide range of debates about social policy. These debates originated in two different theories of population: Malthusian ideas about overpopulation and eugenics – the ‘science’ of selective breeding. An Essay on the Principle of Population by Reverend Thomas Malthus, published in 1798, argued that populations would inevitably increase more r 3.4 Sexuality Just as ‘normal’ parenthood was seen as outside the realm of social policy (although framed and supported by it), sexual practices within marriage were widely seen as an essentially private matter. Foucault (1984) argued that while sexualities were very actively shaped by the Victorians through a range of discourses, particularly those of professional, medical and scientific interests, within marriage it was increasingly an area of silence. Up to the eighteenth century matrimonial re 3.3 Parenthood The deeply embedded inequalities of marriage were also prevalent in parenthood, reflecting the key role of gender in structuring the inequalities found in both. Under common law fathers were given complete control over their children, while mothers had no rights of custody, care or access if the marriage broke down, or even if the husband died. A man could be adulterous or fail to provide for his family without depriving him of his rights. The Poor Laws provided the only legal requirement on 3.2 Marriage Like other areas of personal life and sexuality in the late nineteenth and early twentieth centuries (see Section 1.4), marriage was emerging as a more explicit area of social policy and state regulation, and parenthood and sexuality were being re-examined and reshaped within marriage. In Section 3 we explore changes in the legal framework for marriage and the gender divisions within it. We will begin by looking at one person's story 1.3 Sexuality and parenthood In this unit sexuality is used to refer to heterosexual reproductive sex, relationships and relations, and the meanings and discursive constructions which are associated with these. Sexual practices resulting in conception and the experience of parenthood are among the few remaining areas that are considered a ‘natural’ part of human existence. Just as sexuality has been seen as a ‘natural’, elemental drive in human identity, parenthood has also been closely associated with References Weather and The Water Cycle An Introduction to DNA: Spectrophotometry, Degradation, and the 'Frankengel' Experiment An Experimental System to Study Phagocytosis Allometry: Size and its consequences or...

Students will be able to do activities dealing with weather and water cycles. Learn what makes weather wet and wild, forecast and predict weather.
In this laboratory students perform three exercises as an introduction to the basics of handling and analyzing DNA. In the first, they expose circular plasmid, linear phage, and high molecular weight genomic DNA samples to a variety of physical, thermal, chemical, and enzymatic conditions that might be expected to affect DNA integrity. The DNA's are analyzed by electrophoresis on a group agarose gel. In the second, they pour and reconstruct a "Frankengel" (a gel containing sections with three di

Evolution has resulted in changes in the sizes and forms of organisms. Everything about the biology of an animal, including its physiology, anatomy, and ecology, is influenced by its body size. Frequently there seem to be limits on the sizes that different organisms can attain, even when larger size might be thought to be evolutionarily advantageous. Often an increase or decrease in size is correlated with a change in proportions. Understanding the significance of a particular morphology or inte

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.
Students will learn how to determine map distances and map areas using the map scale. They will also get a better feel for how much an area represents on the map in relation to the size they are suggesting for their cavern.
