In this video segment adapted from NOVA, find out how cars made of a material stronger than steel and half the weight can help combat climate change.

We take a look at the basic composition of blood. Blood is composed of liquids and solids. The solids are called the formed elements while the liquid portion is called plasma. The solids of the blood consists of red blood cells, white blood cells and platelets . The plasma is mostly water, but it does contain some plasma proteins, dissolved gases, nutrients and electrolytes.

In this activity, students consider how several communities are adapting to climate change-related problems including drought's impacts on agriculture, loss of assets due to climate-related hazards, freshwater availability, and extreme heat waves. They will read brief case studies about agro-forestry, insurance strategies, the "Room for the River" program in the Netherlands, water storage from retreating glaciers, and city planning for heat waves. Based on these examples and knowledge of their own community, they will suggest possible adaptation strategies that will be most beneficial to their area.

Students learn about power generation using river currents. A white paper is a focused analysis often used to describe how a technology solves a problem. In this literacy activity, students write a simplified version of a white paper on an alternative electrical power generation technology. In the process, they develop their critical thinking skills and become aware of the challenge and promise of technological innovation that engineers help to make possible. This activity is geared towards fifth grade and older students and computer capabilities are required. Some portions of the activity may be appropriate with younger students.

Children get to know each other through an icebreaker activity that introduces the importance of water on Earth.

This interactive resource adapted from the National Park Service presents the key concepts of cave and karst systems, including how and where they form, different types, and various cave environments.

Summary: Cavitation is the transition of a fluid into vapour due to local reduction of pressure which is generated by high local flow velocities. The transition of a fluid into vapour also occurs during cooking of water by an increase of the local temperature. The term cavitation is generally reserved for conditions in which the temperature of the bulk fluid is not changed. Although cavitation can occur in many situations this course focuses on ship hydrodynamics and ship propellers. The course is divided into five main groups: physics, types and effects of cavitation as well as calculations and test facilities and techniques. Some of these topics are illustrated with the use of videos. (Study goals:) 1. Reproduce the main lines in a selection of the latest developments in the field of propulsion and resistance hydrodynamics, where the current selection of propulsion and resistance topics includes unsteady hydrodynamics of the flow over a foil, cavitation forms, problems and tools for analysis and design, propulsion systems in a service environment and ship drag reduction by air lubrication. 2. Analyse a hydrodynamic problem in the propulsion and resistance area, into well defined sub problems that can be analysed with state of the art knowledge and tools 3. Select the appropriate theory or tool (either numerical or experimental) for an analysis of the identified problem. 4. Reproduce and present to an audience, the main lines in a contemporary publication from the field of Propulsion and Resistance hydrodynamics. 5. Understand, interpret and react to questions from the audience and the lecturer and in doing so, stimulate the scientific debate.

In this lesson, the students look at the components of cells and their functions. The lesson focuses on the difference between prokaryotic and eukaryotic cells. Each part of the cell performs a specific function that is vital for the cell's survival. Bacteria are single-celled organisms that are very important to engineers. Engineers can use bacteria to break down toxic materials in a process called bioremediation, and they can also kill or disable harmful bacteria through disinfection.

The final activity of this unit, which integrates the Keepers of the Gate unit through the Go Public challenge, involves students taking part in experimental design. They design a lab that answers the challenge question: "You are spending the night with your grandmother when your throat starts to feel sore. Your grandma tells you to gargle with salt water and it will feel much better. Thinking this is an old wive's tale, you scoff, but when you try it later that night it works! Why?" Students must have their plan approved by the instructor before they begin. A formal lab write-up is due as part of the laboratory investigation.

In this seminar you will create images of the biologically important structures of the cell membrane. The pictures will be translated to function. You will practice the terminology of these structures to associate their importance in the function of the cell membrane. The inquiry lab will allow you to design a model of the limitations of cell growth due to the cell membrane using water balloons.StandardsBIO.A.2.2.3 Compare and contrast the structure and function of carbohydrates, lipids, proteins, and nucleic acids in organisms.BIO.A.4.2.1 Explain how organisms maintain homeostasis (e.g., thermoregulation, water regulation, oxygen regulation).BIO.A.4.1.3 Describe how endoplasmic reticulum, Golgi apparatus, and other membrane-bound cellular organelles facilitate transport of materials within cells.BIO.A.4.1.2 Compare and contrast the mechanisms that transport materials across the plasma membrane (i.e., passive transport -- diffusion, osmosis, facilitated diffusion; active transport -- pumps, endocytosis, exocytosis).BIO.A.4.1.1 Describe how the structure of the plasma membrane allows it to function as a regulatory structure and/or protective barrier for a cell.

This activity engages learners in exploring the impact of climate change on arctic sea ice in the Bering Sea. They graph and analyze sea ice extent data, conduct a lab on thermal expansion of water, and then observe how a scientist collects long-term data on a bird population.

Developed by a team of scientists from two national laboratories, education researchers, gamers, and a professional game developer, Challenge and Persuade is a highly social, fast-paced, fun-to-play card game in which players compete in applying skills in argumentation. Through game play, players come to understand the many manifestations of how the extreme amplification of the human population, exploding worldwide demand for energy, increasing exploitation of water resources, and alteration of the planet's climateâare tightly intertwined at the nexus of energy, water, and climate; one cannot be considered in isolation from the other two. Development was supported by the National Science Foundation.

It also has an objective of spotting soft land on lunar. Scientific goals include studies of lunar topography, mineralogy, elemental abundance, the lunar exosphere, and signatures of hydroxyl and water ice.

This activity requires construction of a simple salinity tester. Students will create their own calibration scale during this experiment, and look at the change in salinity that would arise if freshwater was suddenly dumped into the ocean. Materials needed for this investigation include a DC mill ampere meter, 2 D-cell batteries and holder, bronze sheeting, #18 solid wire, salt, deionized water, and a stream table or pan apparatus to create a hydrologic model of ice-ocean interaction. Included is a student worksheet to guide interpretation of data. The resource is supported by teacher background information, assessment suggestions, and a scoring rubric. This is Activity 3 of the learning module, Water: Here, There, and Everywhere, part of the lesson series, The Potential Consequences of Climate Variability and Change.

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:

"Many factors affect the evolution of species, but a new influence has recently been recognized. Gut microbes – tiny residents of the intestinal tracts of all animals – have wide-ranging effects on the physiology of their hosts and scientists are increasingly appreciating that diversification may actually be correlated with changes in the gut microbiota. However, the extent to which gut microbes evolve along with a host species remains unclear. A recent study examined this correlation using an ideal model – a system where evolution repeated itself in different geographic settings. Beginning with two groups of Nicaraguan cichlid fish that evolved in parallel in different crater lakes researchers sequenced microbes from fish guts and lake water to determine whether species diverged in parallel. They found that bacterial communities in fish were distinct from those in lake water..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.
