Calisphere Themed Collection - 1870-1900: Closing of the Frontier: Everyday Life and People
The images in this topic show how Californians in the late 19th century worked and played. Many of these photographs reflect the manual labor (mining, logging, agriculture) and services (like barber shops and grocery stores) that supported the rapid growth of cities and towns. As they do today, people spent their free time doing quiet activities like painting, enjoying themselves outdoors, riding bicycles and camping.
Calisphere Themed Collection - 1780-1880: California in Transition: Everyday Life, 1850s-1890s
The images in this topic depict everyday life in California during a time of explosive growth. Even as the state’s mix of cultures became more interconnected, they still managed to maintain and express their unique identities. People at work, at play, posing for formal portraits, and simply walking down the street are part of a diverse and vibrant population.
Calisphere Themed Collection - 1780-1880: California in Transition: Early California Exploration and
California has always been a place of cultural interaction. Early California evolved and changed with each new group of settlers. These images depict the developing interconnectedness of California's early cultures. They also underscore the importance of movement and later settlement of peoples in California. Some of the modern images underscore the contested and often romanticized nature of California’s Spanish and Mexican heritage. This is a collection of primary source images.
Conspicuous Consumption, Conspicuous Waste: Thorsten Veblens Theory of the Leisure Class
One of South Africa's most prominent sociologists, Professor Deborah Posel, gave this Gordon Institute for Performing and Creative Arts (GIPCA) Great TextsBig Questions lecture, discussing "Conspicuous Consumption, Conspicuous Waste". Thorsten Veblen's Theory of the Leisure Class' conspicuous consumption of keeping up with the Joneses' describes the purchase of goods to show status or display wealt. Once more apparent within the nouveau riche or upper-income groups, recent research has indicate

Starting with psychology
The most ‘important and greatest puzzle’ we face as humans is ourselves (Boring, 1950, p. 56). Humans are a puzzle – one that is complex, subtle and multi-layered, and it gets even more complicated as we evolve over time and change in different contexts. When answering the question ‘What makes us who we are?’, psychologists put forward a range of explanations about why people feel, think and behave the way they do. Just when psychologists seem to understand one bit of ‘who we are’
7 Next steps
We all know that the heart is very important but what exactly does the heart do? Why is the blood so important? What functions do the lungs perform? In this unit, we will try to provide at least a basic understanding so we can answer these questions and begin to understand why knowing about the heart is important for all sports people. Before that we will take a look at the human body.
Biotic Indices of Stream Macroinvertebrates for Fun and (Educational) Profit
Water quality monitoring activities can support student inquiry into ecological concepts and pollution issues, as well as offer insight into integrating field and lab work. This exercise provides students with practice in identification (to order or family level) of stream macroinvertebrates that they've previously collected. Provided information indicates water pollution tolerance of the various taxa. Students use the data to calculate several different biotic indices for the macroinvertebrates
Experimental Design and Testing: Hatching and Development in Brine Shrimp
This scientific investigation uses hatching and development in brine shrimp as the biological system in which to demonstrate the laboratory model of teaching experimental design.
School Governors: building relationships
School governors need the skills to develop working relationships with the school community. This unit will help you to understand what each stakeholder within the community needs, from headteacher to pupils and parents. Effective interaction between all parties can prevent problems from arising.

California juniper tree
The juniper tree is a gymnosperm from the phylum of conifers. The cone is the reproductive structure of conifers. The berry-like structures are actually cones where reproduction occurs.
One reason why caecilians are considered to be amphibians is because they go through metamorphosis to reach adulthood. Caecilians are unique amphibians because some of them lay eggs, but some of them give birth to live young.
Butterfly pupa anatomy
The pupa is the third stage of the butterfly's life cycle. The caterpillar creates a pupa, sometimes called a chrysalis, and emerges as the adult butterfly after metamorphosis. The butterfly's wings will be used for flying.
Blooming prickly pear cactus (Opuntia) from the Sonora desert
Cacti are often overlooked as flowering plants. In fact, cacti bloom with colorful flowers and reproduce like all other angiosperms.
One reason why mites are considered to be arachnids is because they don't have wings and they cannot fly. Mites are so tiny that most of them have to be viewed under a microscope to be seen.

Land snails are invertebrates because they do not have a backbone. They are related to water snails, but they do not live in water.
