Swinging Pendulum (for High School)
This activity shows students the engineering importance of understanding the laws of mechanical energy. More specifically, it demonstrates how potential energy can be converted to kinetic energy and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by using the equations for potential and kinetic energy. The equations will be justified as students experimentally measure the speed of the pendulum and compare theory with reality.

Ramp and Review
In this hands-on activity rolling a ball down an incline and having it collide into a cup the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements and use equations that describe these energy of motion concepts to calculate unknown variables, and review the relationships between these concepts.

For Part B you must present:

1. an example from your study or work (say, an assignment, project report, video recording) that shows you can learn using different ways of learning; and,

2. a synthesis of what you have learned, using the different ways of learning included in your example (in 1 above).

Corn for Fuel?!
In this activity, students examine how to grow plants the most efficiently. They imagine that they are designing a biofuels production facility and need to know how to efficiently grow plants to use in this facility. As a means of solving this design problem, they plan a scientific experiment in which they investigate how a given variable (of their choice) affects plant growth. They then make predictions about the outcomes and record their observations after two weeks regarding the condition of

Burdock plant
Burdock seeds are curved and there is a kind of hook on one end of the seed. The hook is easily caught on animal fur and the clothing of humans as they pass by. This helps the seeds spread. This is a commensalistic relationship because the burdock plant benefits while the animal or human is neither harmed nor helped.

3.7 Summary
Hibernation is an ingenious adaptation that some animals employ to survive difficult conditions in winter. This unit examines the differences between hibernation and torpor, and discusses the characteristic signs of hibernation behaviour. It explores the triggers that bring on hibernation, and whether internal signals or external season cues are predominant. It also examines the physiological adaptations that occur in hibernating animals. This unit builds on and develops ideas introduced in the

Alchemy: Distillation
Science in its earliest beginnings consisted of a practice called alchemy. Alchemy includes the study of chemistry, biology, astronomy, spirituality, physics, and art. Distillation or experiments in purification of substances may have been a part of the practice of alchemy.

Human capital theory has been used to show how investments in education and training lead to higher levels of earning. One reason why education and training are referred to as investments is because their benefits accrue over time and because training early in a career leads to higher earnings over the rest of an individual's working life. An important consideration, therefore, in the decision about whether to invest in additional human capital is the potential length of working life over whi

Investigating Animal Respiration with Electronic Probes
This computer-assisted investigation allows students to explore the effect of variables on animal respiration using research-quality instrumentation. The model investigation is with a lizard (anole) exposed to a range of temperatures that are only moderately stressful and do no harm. The animal is contained in a transparent chamber with gas inlet and outlet ports and an electronic thermometer. Carbon dioxide-free air is pumped at a constant rate into the chamber. The outgoing air enriched in car

Caecilian
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.

"I Had to Break the Law to Force Him to Comply:" Lillian Roberts Recalls Organizing State Hospital W
Lillian Roberts came to New York in 1965 during a peak in labor militancy led by state and municipal government employees. Teachers, social workers, and sanitation workers all fought for better working conditions, improved pay scales, and reformed social services. Roberts, an African-American woman from Chicago, was an organizer for the American Federation of State, County, and Municipal Employees (AFSCME), and helped AFSCME's local D.C. 37 win the right to represent thousands of hospital employ

Phylogenetic Investigator
Phylogenetic Investigator (PI) is a software package designed to facilitate creative problem-solving in phylogenetic analysis for the purpose of teaching and learning phylogenetic inference. Users can identify characters and states, polarize characters, and engage in directed-search phylogenetic tree construction. PI also allows the user to * make inferences and represent them one step at a time * vary representational features of their trees (such as angle of divergence and time betwee
