In this video, Jonathan joins Charlie Donilon on his shark charter boat in Rhode Island, Massachusetts, and learns about how shark tagging has shed light on the biology of and behavior of Blue sharks. Tagging has shown that these incredible swimmers actually migrate completely across the Atlantic ocean. Jonathan tries his hand at tagging a shark and then swims with Blue sharks. We also learn that Blue sharks are not nearly as vicious as they have been reputed to be, and the divers are actually able to pet the sharks! Please see the accompanying study guide for educational objectives and discussion points.

Students are introduced to the circulatory system, the heart, and blood flow in the human body. Through guided pre-reading, during-reading and post-reading activities, students learn about the circulatory system's parts, functions and disorders, as well as engineering medical solutions. By cultivating literacy practices as presented in this lesson, students can improve their scientific and technological literacy.

This model allows you to explore why polar and non-polar substances have very different boiling points. While all molecules are attracted to each other, some attractions are stronger than others. Non-polar molecules are attracted through a London dispersion attraction; polar molecules are attracted through both the London dispersion force and the stronger dipole-dipole attraction. The force of attractions between molecules has consequences for their interactions in physical, chemical and biological applications.

Storms can have devastating impacts on coastal communities. Typically, tropical storms like hurricanes get the most attention, but there are other types of storms that occur at more northern latitudes that can be just as destructive. For example, in January of 2018, Winter Storm Grayson caused more than 300,000 power outages and $1.1 billion in damage, and resulted in 22 confirmed casualties along the eastern seaboard. In this module, students will learn how barometric pressure changes during a storm, analyze the effect of storms on oceanographic variables, classify a storm as a bomb cyclone, and compare a bomb cyclone to a hurricane. Ultimately students will use their quantitative reasoning skills to manipulate and visualize data during storms in the northeastern United States.

Students learn about the role engineers and engineering play in repairing severe bone fractures. They acquire knowledge about the design and development of implant rods, pins, plates, screws and bone grafts. They learn about materials science, biocompatibility and minimally-invasive surgery.

Students examine an image produced by a cabinet x-ray system to determine if it is a quality bone mineral density image. They write in their journals about what they need to know to be able to make this judgment. Students learn about what bone mineral density is, how a BMD image can be obtained, and how it is related to the x-ray field. Students examine the process used to obtain a BMD image and how this process is related to mathematics, primarily through logarithmic functions. They study the relationship between logarithms and exponents, the properties of logarithms, common and natural logarithms, solving exponential equations and Beer's law.

Students investigate the bone structure of a turkey femur and then create their own prototype versions as if they are biomedical engineers designing bone transplants for a bird. The challenge is to mimic the size, shape, structure, mass and density of the real bone. Students begin by watching a TED Talk about printing a human kidney and reading a news article about 3D printing a replacement bone for an eagle. Then teams gather data—using calipers to get the exact turkey femur measurements—and determine the bone’s mass and density. They make to-scale sketches of the bone and then use modeling clay, plastic drinking straws and pipe cleaners to create 3D prototypes of the bone. Next, groups each cut and measure a turkey femur cross-section, which they draw in CAD software and then print on a 3D printer. Students reflect on the design/build process and the challenges encountered when making realistic bone replacements. A pre/post-quiz, worksheet and rubric are included. If no 3D printer, shorten the activity by just making the hand-generated replicate bones.

After learning, comparing and contrasting the steps of the engineering design process (EDP) and scientific method, students review the human skeletal system, including the major bones, bone types, bone functions and bone tissues, as well as other details about bone composition. Students then pair-read an article about bones and bone growth and compile their notes to summarize the article. Finally, students complete a homework assignment to review the major bones in the human body, preparing them for the associated activities in which they create and test prototype replacement bones with appropriate densities. Two PowerPoint(TM) presentations, pre-/post-test, handout and worksheet are provided.

Each student selects a popular science book on a geoscience topic of interest to them, finds two book reviews of that book, and writes a book review that includes some description of the book as well as some commentary and review. Each student also gives a short (three-four minute) oral presentation of their review to their classmates (either stand-alone or with one Powerpoint slide).

In January of 2003, CSUF drilled and completed a deep multiport-monitoring well on the north side of campus. This was done in order to gain a better understanding of the local subsurface geology and groundwater conditions in and around CSUF. Samples were collected from the drill hole (boring) every 5-feet. The total depth of the well is 870 feet below ground surface (grade). Borehole geophysical data (E-log) information was collected from the boring prior to the installation of the well pipe. As you describe the soil samples, compare and contrast your findings to those of the geophysical signature (gamma-ray log) found in the accompanying "E-log" for the boring.

Preparation requires lecture and/or reading material on stereonet methods in plotting small circles, and on making stereonet rotations along small circles. In lab, students are given a description of the problem, along with a schematic cross section on the blackboard showing how the dip of the eastern fold limb is not constrained, but how the orientation of cross beds in an unoriented core are the only data available to help constrain the dip of the fold limb. Students are then given a while (~20 minutes) to think about and discuss how a solution can be made. An open class discussion follows, and then I guide the students through the answer. An alternative method is to let the students take a week to think about and solve the problem with little or no help.

Question
Over the last 70 million years or so, the Hawaiian Hot Spot has been pumping out lava, a total of about 775,000 km3 worth. As the Pacific Plate has moved over the hot spot, the volcanic peaks and plateaus of the Hawaiian-Emperor seamount chain have formed. If all of that lava had erupted in California, how deeply would California be buried in lava?

Question Suppose that you are building a new house. It will take about 90 kg (198 pounds) of copper to do the electrical wiring. In order to get the copper in the first place, someone needs to mine solid rock that contains copper, extract the copper minerals, throw away the waste rock, and smelt the copper minerals to produce copper metal. Rocks mined for copper typically contain only very small percentages of copper -- about 0.7% in the case of most of the big porphyry copper deposits of the world. How much rock would someone have to mine in order to extract enough copper to wire your new house?

Question In 1983, an eruption began at Kilauea Volcano in Hawaii that has proved to be the largest and longest-lived eruption since records began in 1823. Lava has poured out of the volcano at an average rate of about 160 million m3 per year. To put those flow rates into perspective, let's suppose that the volcano was erupting directly into your classroom. At these flow rates, how long would it take to fill your classroom with lava?

Question Let's suppose that you have a shoe box full of water (the box is waterproof, of course). The shoe box weighs about 9 kg (19.8 pounds). Suppose you emptied the box and filled it completely with rock (little or no air space). How much would it weigh? Let's empty the box again and fill it completely with pure gold. How much would the box weigh now?

After some in and out of class practice with mineral and rock id, students are divided into groups of about 5 and taken to locations where boulders and cobbles are used as decorative landscaping (usually adjacent to streets or on short slopes). This seems to work best if class sizes are about 25 or less - then instructors can keep track of groups in an area. Groups are given an area about 5 feet wide and 25 long (enough for several hundred cobbles/boulders) and told to identify 6-12 rocks of different types (at least 2 each if only doing Ig, Met, Sed.- more if rock names expected). 1.) In the first stage groups are given a fairly long time (~20-25 minutes) to pick and identify rocks with flags and markers. This seems like a long time and normally they can quickly flag and name the easiest rocks in their area. However, they only get one point for each rock correctly identified at this stage. 2.) In the second stage groups get 10 minutes to inspect all other groups' areas and mark those rocks they think other groups INCORRECTLY identified. They are allowed to send one person from their group to inspect each of the other groups' areas. Their group gets 5 pts for each correctly mis-identified rock of another group. 3.) In the third stage, groups can defend their identifications to the instructor/TA and get 10 points if they prove that another group flagged/id'd one of their identifications incorrectly - the mistaken group gets docked 10 points. The key to this exercise is that in the first stage some of the students should realize that they get many more points for making other groups mis-identify their rocks, and that all of their own group members should be trained to have enough expertise to identify tricky or difficult rocks. This is the reason for the excess time at the first stage, for training, review, and typically the group will change their chosen rocks to include the most difficult ones rather than the easiest. Should groups not realize this - the instructor might want to prompt them.Students are allowed Rock charts, cheat sheets, etc. at the instructors decision.
