The first problem in this assignment is the culmination of the unit on energy balance and greenhouse gases. The students have already calculated blackbody temperatures as a function of albedo, sun's luminosity and distance from sun. They have also already calculated the magnitude of the greenhouse effect (optical thickness) of the modern atmosphere. In this first problem, the students apply these same calculations to the Faint Young Sun hypothesis and infer what can account for the geological evidence for liquid water on earth since 4.3 Ga. The second problem follows an introductory lecture on radiometric decay and radiometric dating. The students have seen the decay equation and learned what are decay constants and stable versus radioactive isotopes. In this problem, the students apply these concepts to radiocarbon.

Students drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. They follow good experiment protocol, take measurements, calculate averages and graph results. In seeing how falling water can be used to do work, they also learn how this energy transformation figures into the engineering design and construction of hydroelectric power plants, dams and reservoirs.

In this video from Common Ground and Cleaner Water, Tribby Vice, a Kentucky farmer, talks about the changes he has made on his farm to protect the water quality of the stream running through his property and the watershed in which he lives.

In this lesson, students investigate photosynthesis through hands-on experiments, videos, and discussion of text. They work in small groups with picture cards to create a chart showing how plants transform carbon dioxide, water, and light energy into carbohydrates and oxygen. After working collaboratively, students will create their own diagrams of photosynthesis. Because plant observations must occur over time, this lesson will take several days to complete. This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

In this video segment adapted from NOVA scienceNOW, scientists in western Greenland explain how a glacier there is shrinking and moving faster due to increased melting.

This video describes how field research -- in this case, making water measurements in rugged mountain locations -- helps us to understand the complex relationships among changing climate, populations, and water usage.

In this activity students use published data from the Massachusetts Military Reservation to observe and predict mass transport parameters.

In this lesson, students will watch a video/teacher demonstration on how to properly fill a syringe.  The students will mime the procedure while the teacher reviews the procedures.  Students will also practice with a syringe, needle, and sterile water bottle.  Once the students are comfortable with the procedures, they will make a recording of their demonstration to be submitted for grading.NE.AFNR.HS.28.5.b or NE.AFNR.HS.29.5.b

The project is to bring together what students learned through lectures, and weekly exercises and lab practices and to apply remote sensing technology to your interested application area. The objective of the project is to extract land cover information for an area covering the Amherst area. Students are required to classify the land cover of the selected area into 3-5 classes such as vegetation cover, water body (lake or reservoir or river) and settlements (residential and commercial landuse). The classification should be conducted by using both images with spatial resolution of 30 and 15 meters). And then they need to compare the accuracy of classifications from using images at different spatial resolutions. This project provides students with a very useful experience of extracting land cover information from satellite images.

Students create their own simple compasses using thread, needle and water in a bowl and learn how it works.

Students will be exposed to three different scenarios. The scenarios will require that students hypothesize two solutions, test their hypotheses, document the results, and document the property that proved the effectiveness of the material chosen. An example of a scenario would be, "When provided toilet paper, tissue paper and paper towels, which material would be most effective in cleaning spilled water, and what property makes it so effective?" Students will then present the data collected in a Google Slides presentation. The lesson's total duration is about six days. This unit was created as part of the ALEX Interdisciplinary Resource Development Summit.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Blue-green algae, or cyanobacteria, are photosynthetic bacteria that live in water and are important oxygen producers. Human-driven changes are a major factor causing seasonal cyanobacterial blooms, which can cause mass death of aquatic animals. Bacteria-infecting viruses, called phages, could potentially be used to control these outbreaks with minimal environmental disruption. But to date few freshwater ‘cyanophages’ have been isolated or had their genomes sequenced. Recently, researchers isolated a strain of cyanobacteria from Lake Chaohu, a massive lake in China with seasonal cyanobacterial blooms. Using the new cyanobacteria strain, they isolated five new freshwater cyanophages with varying tail structures from the same lake. While viruses can have RNA genomes or even single-stranded DNA genomes, all five isolated phages had double-stranded DNA genomes. Further analysis suggested that they all use different DNA packaging mechanisms and are evolutionarily distinct..."

Students further their understanding of the salmon life cycle and the human structures and actions that aid in the migration of fish around hydroelectric dams by playing an animated PowerPoint game involving a fish that must climb a fish ladder to get over a dam. They first brainstorm their own ideas, and then learn about existing ways engineers have made dams "friendlier" to migrating fish, before being quizzed as part of the game.

Approximately 600,000 sea birds die each year by getting caught on hooks used in line fishing. A device called the Hookpod, invented by a UK company in Devon, has a clever solution to this problem. The fish hook is covered by a case so birds cannot get hooked. At a certain depth (below the diving depth of indigenous birds) a mechanism is triggered to release the case which floats to the surface and is retrieved to be used again. These lesson ideas provide an interesting practical idea to use a particle model to explain density and pressure in a gas. Students will then take part in a STEM design challenge to make a device to respond to a pressure change at a particular depth of water.

A facetious, and somewhat racist, look at public opinion surrounding the controversy over American fishing rights in British-controlled waters off North America. (See also "John Bull's Fish Monopoly," no. 1852-4.) Four men, all stereotypes, debate the issue and agree on American claims to the rights. A Yankee (seated, far left) motions with his cigar and declares, "I go in for liberty to ketch all the fish I want--I've been in the fish bizness myself and sold porgies for two year on the Avenue." A knock-kneed black man in a wide-brimmed hat and patched trousers agrees, "Ah dat's it Boss! Den you knows all about it ob course. I neber sold porgies, but I hab opened clams and biled lobster. & I tink the freedom ob the seas belongs to us--I does for sartain." To emphasize the point, he stabs the palm of his hand with his forefinger. A Dutchman smoking a large meerschaum pipe adds, "Vell den vot shall I told der British? I shall said go to der duyvil mit your dreaties! Codfish shall pe more goot as de dreaties--I shall ketch de fish & you was ketch de dreaties, py Dam!" At far right stands a bewhiskered Irishman, his hand resting on what appears to be a butter-churn(?). He concludes, "Arrah be aisy now! Only put little Frank Pierce [i.e., Democratic presidential nominee Franklin Pierce] in the chair and he'll settle the question in a jiffy." The collection of character types as well as the drawing style in the print are recognizable as the work of Edward Williams Clay. Compare it, for instance, with his "Seven Stages of the Office-Seeker" and "Ultimatum on the Oregon Question (nos.&1 1852-8 and 1846-1).
