Observe the origins of some ocean floor sediments
This Earth science resource illustrates the sources of ocean sedimentation along coasts, on the ocean floor, and at hydrothermal vents. Students click on these ocean locations to see examples of the formation of hydrogenous, biogenous, and terrigenous sediments. For each sediment type, the resource provides two enlargeable images. When enlarged, each image is accompanied by descriptive text. For example, the hydrogenous sediments are represented by a close-up view of ferromanganese nodules, as w
Cold Clouds and Water in Space
This article from Astrobiology Magazine reports on the discovery of water in cold regions of space. Using data from the European Space Agencys Infrared Space Observatory, astronomers have determined that water is abundant in these cold, or quiescent regions of space where there are no stars, and that the majority of it occurs as ice with a small amount of water vapor. It is thought that these cold regions of space might be the future birthplaces of low-mass stars like our own sun. Links to other
Spontaneous generation
This lesson demonstrates that scientific knowledge is stable, but also prone to change. Students will understand how those changes can happen in the context of the history of spontaneous generation. This lesson from the American Association for the Advancement of Science aligns with Benchmarks 1 and 10, Nature of Science, and History of Science. It can be done as a class or via student independent study. Part of the lesson involves students accessing related information on the Internet. Thorough
Science Sampler : Creating caddisfly cases
The larval stage of a northern casemaker caddisfly provides a creative hands-on activity for students while also introducing them to aquatic insect development and adaptations to stream life. This project is an opportunity to study the role of this invertebrate in the food web of a stream.
3.2 Removal of iron
This unit looks at the methods that have been developed by organisms for the uptake, transport and storage of iron: a process made more complicated by the insolubility of its oxides and hydroxides. You will examine iron storage in mammals, including humans, is achieved by ferritin, which stores iron as a hydrated iron (III) oxide – an example of biomineralisation.
Science and Technology
The goal of engineering is to solve practical problems through the development or use of technologies. Technology/engineering works in conjunction with science to expand our capacity to understand the world.
Measurement
Measurement is best learned through direct applications or as part of other mathematical topics. A measurable attribute of an object is a characteristic that is most readily quantified and compared. Many attributes, such as length, perimeter, area, volume, and angle measure, come from the geometric realm. Other attributes are physical, such as temperature and mass. Still other attributes, such as density, are not readily measurable by direct means.
Life Science
The life sciences investigate the diversity, complexity, and interconnectedness of life on earth. Students are naturally drawn to examine living things, and as they progress through the grade levels, they become capable of understanding the theories and models that scientists use to explain observations of nature.
2.4 What does relationship mean in systematics? E. Mayr
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.

5 Summary
Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This unit will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.
Don't Crack Humpty
Student groups are provided with a generic car base. The groups then design a device/enclosure that will protect an egg on or in the car as it is rolled down a ramp at increasing slopes. Students will be expected to perform basic mathematical calculations using their data.
Wind Chimes
Using their knowledge of physics, students will build a wind chime. Mathematical computations will be done to determine the length of the pipes.
Learn to Build a Rocket in 5 Days or Your Money Back
In this lesson, students discover the entire process that goes into designing a rocket for any customer. In prior lessons, students learned how rockets work, but now they learn what real-world decisions engineers have to make when designing and building a rocket. They learn about important factors such as supplies, ethics, deadlines and budgets. Also, students learn about the Engineering process, and recognize that the first design is almost never the final design. Re-Engineering is a critical s
9 The factory reform movement
Childcare, education, working conditions, healthcare, crime … these issues are hotly debated in today's society. They are also issues that Robert Owen, seen by some as a visionary and by others as a knave and a charlatan, sought to address in the early 1800s. This unit uses a series of essays written by Owen to explore the ideas of this important and controversial figure.
Wire Maze
Students will build a wire circuit and pass a paperclip through the maze, trying not to touch the wire. Touching the wire with the paperclip will cause the circuit to close, which will activate the indicator.
Which Roof is Tops?
When you walk or drive around your neighborhood what do the roofs look like? What if you lived in an area with a different climate, how would that effect the style of roof that you might find. This is an introductory activity to explore the advantages of different roof shapes for different climates or situations.

Decarteret matches pole vault record at Florida State
The Northeastern women's track & field team recorded 15 top-10 marks, including another record-breaking performance by Jillena Decarteret, amidst stiff competition at this weekend's Florida State Relays in Tallahassee, Fla.
Decarteret tied the school record in the pole vault with a winning performance of 4.06m (13'3.75), beating out 20 others for the title. The sophomore's vault matched Laura Chmielewski's mark set back almost seven years ago on May 8, 2004. Decarteret has continued to make upw
