Water Vapor Protocol
The purpose of this activity is to measure the total precipitable water vapor (column water vapor) in the atmosphere above an observer's site. Students point a GLOBE/GIFTS water vapor instrument at the sun and record the voltage readings from a digital voltmeter. They observe sky conditions near the Sun and perform the Cloud Protocols. Intended outcomes are that students understand the concept that the atmosphere prevents some of the sun's light from reaching Earth's surface, how water vapor mea
The purpose of this activity is to measure the aerosol optical thickness of the atmosphere (how much of the sun's light is scattered or absorbed by particles suspended in the air). Students point a GLOBE sun photometer at the sun and record the largest voltage reading they obtain on a digital voltmeter connected to the photometer. Students observe sky conditions near the sun, perform the Cloud, Optional Barometric Pressure (optional) and Relative Humidity Protocols, and measure current air tempe

Momodou Ceesay talks about the function of an artist
Gambian artist Momodou Ceesay, painting instructor at the Elma Lewis School of Fine Arts and at Roxbury Community College, talks about his function as an artist and his recent work illustrating African stories for children.
The Changing Geographic Distribution of Malaria with Global Climate Warming
In this exercise, students analyze climate data to find areas in the southern United States that are now close to having conditions in which the malaria parasite and its mosquito hosts thrive. Then they attempt to forecast when areas might become climatically suitable. Learning goals, context for use, ...
Biomechatronics is a contraction of biomechanics and mechatronics. In this course the function and coordination of the human motion apparatus is the central focus, and the design of assistive devices for the support of the function of the motion apparatus.
Stochastic Evolution Equati
The lectures are at a beginning graduate level and assume only basic familiarity with Functional Analysis and Probability Theory. Topics covered include: Random variables in Banach spaces: Gaussian random variables, contraction principles, Kahane-Khintchine inequality, Anderson’s inequality. Stochastic ...
Highlight the meaning of a function, and see how it can be seen as something changing over time, with this tool that links a motion model to a graph.
Mating preference in the commercially imported bumblebee species Bombus terrestris in Britain (Hymen
Commercial trade of bumblebees in Europe results in different subspecies of Bombus terrestris being shipped into regions where they are not native. Although previous studies have shown that these subspecies will interbreed, none have assessed mating preference of the different populations. This study examines the mating preferences between two geographically isolated populations of B. terrestris which have unnaturally been brought together through the commercial trade in bumblebees. Under contr
The Effects of Cattle Grazing on Vegetation in a Shortgrass Prairie Ecosystem
Grazing by large herbivores has profound effects on both the structure and function of shortgrass prairie ecosystems. In this exercise a grazed section of prairie on a working cattle ranch is compared to a less grazed section on an adjacent wildlife refuge. The Daubenmire canopy-coverage method is used ...
Using Bromelain in Pineapple Juice to Investigate Enzyme Function
This investigation introduces students to the structure and function of the proteolytic enzyme, bromelain, which is present in large quantities in the fruit, leaves, and stems of pineapple. In this lab exercise, students study the rate at which bromelain catalyzes the hydrolysis of gelatin (substrate) at different temperatures and pHs. Strips of developed black and white photographic film are placed in freshly squeezed pineapple juice under different experimental conditions. The time it takes fo
Thinking Systematically -- Grade 6 (Japan)
"Thinking Systematically" teaches students to find the value of two quantities that satisfy two conditions. Students are asked to determine the number of pencils and ballpoint pens bought if the total number of items purchased was 10 and the total price was 460 yen.
CVs and Letters to Employers
CV’s and Letters to Employers is one of several Futures workbooks which help students choose and prepare for their careers. Like the other workbooks in the series you can dip in and out doing the exercises which are most relevant to you. You might want to include the exercises or the output in your personal development plan or e-portfolio.
International Classification of Function, Disability and Health
This package was originally designed for undergraduates in Medicine at the University of Nottingham. It will also be useful to students in nursing, allied health professions and pharmacy. Practitioners in these fields, who are new to the ICF, will also find it a useful introduction. It describes the International Classification of Functioning, Disability and Health (ICF), a classification system published by the World Health Organisation to describe health status. This system is widely used in
Uniform convergence and pointwise convergence
The aim of this material is to introduce the student to two notions of convergence for sequences of real-valued functions. The notion of pointwise convergence is relatively straightforward, but the notion of uniform convergence is more subtle. Uniform convergence is explained in terms of closed function balls and the new notion of sets absorbing sequences. The differences between the two types of convergence are illustrated with several examples. Some standard facts are also discussed: a unifo
032 The Philippe de Montebello Years: Mangaaka Power Figure
