Population Growth in Yeasts
This lesson is the second of two that explore cellular respiration and population growth in yeasts. In the first lesson, students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Based on questions that arose during the first lesson and its associated activity, in this lesson students work in small groups to design experiments that will determine how environmental factors affect yeast population growth.
Make Your Own Recycled Paper
Students will learn about how paper is made. Working together, students will make their own paper. This activity introduces students to recycling; what it is, its importance, and how it affects their lives.
Form vs. Function
Students model and design the sound environment for a room. They analyze the sound performance of different materials that symbolize wallpaper, thick curtains, and sound-absorbing panels. Referring to the results of this analysis, they then design another room based on certain specifications and test their design.
Buoyant Boats
Students will conduct a simple experiment to see how the water level changes in a beaker when a lump of clay sinks in the water and when the same lump of clay is shaped into a bowl that floats in the water. They will notice that the floating clay displaces more water than the sinking clay does, a result that will probably surprise them. They will then determine the mass of water that is displaced when the clay floats in the water. A comparison of this mass to the mass of the clay itself should r
Powerful Pulleys
Students continue to explore the story of building a pyramid, learning about the simple machine called a pulley. They learn how a pulley can be used to change the direction of applied forces and move/lift extremely heavy objects, and the powerful mechanical advantages of using a multiple-pulley system. Students perform a simple demonstration to see the mechanical advantage of using a pulley, and they identify modern day engineering applications of pulleys. In a hands-on activity, they see how a
Engineering in Sports
Imagining themselves arriving at the Olympic gold medal soccer game in Beijing, students begin to think about how engineering is involved in sports. After a discussion of kinetic and potential energy, an associated hands-on activity gives students an opportunity to explore energy absorbing materials as they try to protect an egg from being crushed.
Earthquakes Rock!
Students learn the two main methods to measure earthquakes, the Richter Scale and the Mercalli Scale. They make a model of a seismograph a measuring device that records an earthquake on a seismogram. Students also investigate which structural designs are most likely to survive an earthquake. And, they illustrate an informational guide to the Mercalli Scale.
Introduction This unit covers a few key topics that will help you to think in broad ways about how you and others take decisions; we shall also introduce you to some themes in social science which have direct relevance to managerial decision making. The approach of this unit is descriptive: rather than prescribing how you should make decisions we look at frameworks that will help you to understand how decisions are actually made. We aim to help you to develop greater insight into both your own deci

Mount St. Helens, Washington homepage
This USGS web page contains images from the Mount Saint Helens eruptions. The site contains information about the 1980 eruption, activity before, during, and after and previous eruptions. The site also contains maps, current hazards reports, background information and more.
Images of the Sun
Skylab's solar experiments captured images of the sun in incredible detail and revealed unknown aspects of the Sun.
Introduction People have always communicated with each other – initially by face-to-face communication through gestures and sounds, then over a distance through written messages and signals in the form of fires, lights or flags. Technology, for instance in the form of electrical signals, has reduced many of the limitations of distance. Communication networks have become very important, and modern society depends on them for the smooth operation of economic and social activities. In this unit we regard a

3.2 What do children and parents think of teaching assistants? Curiously, little has been written about their perspectives. A small-scale study involving 78 primary-aged children in England (Eyres et al., 2004) showed that children can, when asked, differentiate between their own class teacher and other adults who work with them. However, the children reported a substantial overlap between the activities of teachers and teaching assistants. For instance, eight-year-old Sarah said: 2.2 Profile of teaching assistants: an overview Traditionally the primary education sector has employed a high proportion of women teachers. In England and Wales in 1980, male teachers constituted around 23 per cent and female teachers 77 per cent of the workforce (DES, 1980). By 1999 the number of men had decreased to 17 per cent and that of women had increased to 83 per cent (DfES, 2002). There is reason to think that this trend is continuing. Primary teaching is certainly a ‘feminised’ workforce, but there are also anomalies re Acknowledgements Except for third party materials and otherwise stated (see terms and conditions), this content is made available under a Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Licence.
