Mrs. Matthews Centers for the week of September 27
The students in Mrs. Matthews science class have been studying plants this week. They have been learning the parts of a plant, parts of a flower, parts of a seed, and various jobs a plant has. The students work through six centers throughout the week. The centers include (1) an art activity about pollination (2) an A.R. book about pollination (3) several interactive websites about the growth of plants and how plants respond to light and gravity (4) an art activity about the life cycle of a
The Color Song
This video shows the primary colors and how to spell each color. Students will be engaged by the voice of children their own age. Also the song is simple and can help build associations between the word and the actual color. This is great for a preschool or kindergarten classroom.
Transport of Water and Salts in Plants - Part 1
This is part 1 of a short, animated video (03:37) that offers information about the transport of water and salts in plants from the roots to the stems.
Inside a Solar Cell
In this interactive activity adapted from NOVA Online, learn how a typical photovoltaic cell converts solar energy into electricity. Explore the components of a photovoltaic cell, including the silicon layers, metal backing, antireflective coating, and metal conductor strips. Using animations, investigate why the silicon layers are doped with phosphorous and boron, and how an electric field is used to generate electricity from sunlight. No audio.
The Effects of Green House Gases
Methane, water vapour, nitrous oxide and ozone are the green houses
gases, which exist in the earth’s atmosphere. They absorb thermal
radiations that are breathed out by the earth’s surface and reflect it
back to the earth, thereby serving as a blanket preventing the earth
from heat loss and keeping temperatures constant and perfect for animals
to live, and plants to grow.
For years now, rising temperatures have been a particularly hot topic

Basics of Entrepreneurship: Why Start-ups Fail at Marketing -- and Possible Solutions
Why do more than half of all start-ups fail? Because they bungle their marketing, according to Leonard Lodish, a professor of marketing at Wharton and co-author of two books, Entrepreneurial Marketing and Marketing That Works. "The dogs won't eat the dog food is the way venture capitalists describe it," Lodish says. The key lies in how a marketing plan is crafted. In this installment of the podcast series for the Wharton-CERT Business Plan Competition, Lodish explains that marketing plans must t

Earth Exploration Toolbook Chapter: When is Dinner Served? Predicting the Spring Phytoplankton Bloom
In this activity, users learn about the variables that influence the abundance of phytoplankton, the microscopic plants that form the base of the marine food chain. Users apply this knowledge to make predictions about the timing of the spring phytoplankton bloom in the Gulf of Maine. They obtain and graph data from buoy monitoring stations and interpret them to make their predictions. They check their predictions by examining chlorophyll concentration data at each buoy. Users also compare their
The benefits to employers of raising workforce basic skills levels: a review of the literature
This paper summarises the literature on the benefits which employers derive from raising the basic skills levels of the workforce. Because the evidence on basic skills in the workplace is still quite sparse, the review also covers the benefits to individuals of improving basic skills and looks at the literature on the benefits of training for employers, and employees, more generally. The aims of the literature review were to review and synthesise the existing literature on the economic and wide
Health inequalities and the welfare state: perspectives from social epidemiology
It might be assumed that welfare states that have done so much to reduce inequality of opportunity have also reduced inequality of health outcomes. While great advances have been seen in reducing the rates of many diseases in welfare states, disparities in health have not been eliminated. Is it the case that lowering risks overall will leave disparities that cannot be remediated, and that such efforts are at the point of diminishing returns? The evidence suggests that this is not true. Instead t

EMBODYING RESEARCH: A STUDY OF STUDENT ENGAGEMENT IN RESEARCH WRITING
College students often perceive the university as alienating; reading and writing impersonal research texts can intensify this sense of disconnect. College professors often feel passion and enthusiasm toward their own research yet find it difficult to create this excitement in their research writing classrooms. This qualitative study explored student and teacher perceptions and instructional approaches in a university research writing course, seeking clues to student engagement. Data collecti
