As Charlotte uses her web to communicate, the students will also create a web to send a small message. The students will learn how a spider creates its web, and about the different types of webs spiders make. With this knowledge, the students will design and create their own web and incorporate a message.
Sound Booth Construction
Students explore the sound dampening ability of numerous materials by designing and prototyping model sound booths. As a result, students learn about how sound is reflected, absorbed and travels through various materials, thus giving them an overview of sound dampening, energy absorption and sound propagation in the context of engineering. Students also create blueprints and document their findings in a formal lab report.
3.5.1 Expectancy versus effect One of the biggest problems in evaluating psychological interventions is that even if a treatment appears to ‘work’ it can still be difficult to ascertain whether the results were a consequence of the treatment itself. The improvement might have occurred anyway, with or without the treatment, or the apparent benefits might have resulted from other factors, such as being able to discuss the difficulties with a professional who understands. Any treatment can lead to expectations

Spot-Overlay Ames Test of Potential Mutagens
This protocol represents a cost-effective modification of the Ames Test that allows students to investigate the mutagenic potential of various common substances. Potential mutagens are tested using well-characterized auxotrophic strains of Salmonella typhimurium. By analyzing the results, students determine if any of their compounds may be mutagenic. Follow-up experiments are designed to determine the dose response of these potential mutagens. Using this protocol, we have achieved reproducible r

Shelly is a 38-year-old African American female who initially presented with transverse myelitis 2 years ago. A lumbar puncture revealed multiple oligoclonal bands in the cerebral spinal fluid. MRI has demonstrated numerous plaques in the bilateral cerebral white matter. She eventually went on to recover from her initial attack but since her second attack has continued to progressively worsen. Her gait and other motor functioning have deteriorated and she is now wheelchair bound.

Milkweed bugs after molting
These milkweed bugs have molted their outer coverings so they can grow into adults. Milkweed bugs look lighter in color after they have molted.
In this interactive activity adapted from Wake Forest University, observe how rotational force, or torque, is related to the distance between the pivot and the point of the applied force.
Fear of Crime
The purpose of this module is to introduce students in an online Criminology course to the idea of data analysis using an online analysis program and the General Social Survey. Prior to this module, students will have read several documents describing the scientific method including terminology such as statistical significance, independent and dependent variables, and operationalization. Once students have read this document, they then complete a guided online analysis and turn in their answers
Who Are the Poor?
In this assignment, we will perform a simple analysis of poor households in the United States, considering whether certain kinds of households are more likely to be poor and what sorts of households make up the largest proportion of the poor. Students will be looking at three characteristics that may be associated with poverty: race, age, and family type.

"In School Days" by John Greenleaf Whittier (poetry reading)
An American poem. The British find American sentimentality and sincerity hard to bear - just as Americans find British irony and dry humour baffling. The picture of the Californian School House looks as though it was taken in about 1930 - it comes from this site: http://cerritos.org/community/history-of-the-region The Schoolroom was painted by William Bromley Still sits the school-house by the road, A ragged beggar sleeping; Around it still the sumachs grow, And blackberry-vines are creep
