Because of the events of WWI, airplane technology developed rapidly. Learn how airplanes changed in this short time, how other technology advanced, and how airplanes were used throughout WWI.
Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.
This is an activity about satellite flight. Learners will first watch a video about the orbit and formation of the MMS satellites to learn about their flight configuration. After, they will research similar facts about other types of satellites. Next, learners will compute the volume of MMS' tetrahedral flight configuration and investigate how the tetrahedral volume changes as the satellites change positions. Finally, they will create a report that outlines their findings.This activity requires student access to internet accessible computers. This is lesson three as part of the MMS Mission Educator's Instructional Guide.
This animation adapted from NASA shows the orbital paths of spacecraft in NASA's Earth Observing Fleet that are a source of wide-scale, primary research about Earth.
Use a virtual scanning tunneling microscope (STM) to observe electron behavior in an atomic-scale world. Walk through the principles of this technology step-by-step. First learn how the STM works. Then try it yourself! Use a virtual STM to manipulate individual atoms by scanning for, picking up, and moving electrons. Finally, explore the advantages and disadvantages of the two modes of an STM: the constant-height mode and the constant-current mode.
This online board game involves moving a "research blimp" around the world. Advancing the blimp depends on spinning an embedded wheel and then correctly answering questions related to weather.
In this issue of the free online magazine Beyond Penguins and Polar Bears, learn about the tools and technologies scientists use to study the land, ice, ocean, atmosphere, and living creatures of the polar regions. Students can also learn about the day-to-day life of a scientist working at the South Pole and plan their own research expedition.
This activity is a forensic based physical science inquiry investigation where students collaborate in groups and use observations to determine how Newton's Laws of Motion are applied in finding evidence in a car and truck trailer accident. Their evidence will be used in a presentation to verify consistency in police and witness reports to support the plantiff or defendent in the court case.
This website was created by the GMO working group in the UConn College of Agriculture, Health and Natural Resources. We offer clear descriptions and explanations of a variety of issues related to genetically modified organisms, or GMOs. We hope you find the information useful, and we welcome your feedback. We thank Purdue Agriculture for inspiration, the format and assistance in building this site.
Students use data acquisition equipment to learn about force and displacement in regard to simple and complex machines. In the engineering world, materials and systems are tested by applying forces and measuring the resulting displacements. The relationship between the force applied on a material, and its resulting displacement, is a distinct property of the material, which is measured in order to evaluate the material for correct use in structures and machines.
Learn how to use the Chrome extension called Screencastify to create easy and meaningful screencasts.
At first glance, starfish, more properly called sea stars, arenŰŞt doing much of anything. In this video, JonathanŰŞs investigations reveal a slow-motion predator that hunts and attacks its prey. Traveling the world, Jonathan investigates sea stars from the tropics to the Antarctic and uses time-lapse photography to reveal an amazing complexity to the world of the sea star. Please see the accompanying study guide for educational objectives and discussion points.
Cryptids, creatures of questionable existence, are used as a source of data to guide students into the creation of their own GIS data layer in Google Earth. The activity serves the purpose of a tutorial to teach students how to make data layers with a simple subject. Then they use that skill on other topics such as plastics in their neighborhood.
This worksheet provides a pair of satellite world maps, showing vegetation in January and July, and has a series of questions guiding exploration of the similarities and differences in the two images. The activity is from Space Update, a collection of multimedia educational resources about the Earth and Space. Summary background information, data and images supporting the activity are available on the Earth Update data site.
This lesson uses NASA satellite data to correlate cloud cover over Africa to the solar declination. The student will access NASA data using the MY NASA DATA Live Access Server and import the data into Excel spreadsheet software. Students will use NASA satellite data to correlate cloud cover over Africa to the solar declination.
Explore your own straight-line motion using a motion sensor to generate distance versus time graphs of your own motion. Learn how changes in speed and direction affect the graph, and gain an understanding of how motion can be represented on a graph.
In this activity, students use Google Earth to investigate a variety of renewable energy sources and select sites within the United States that would be appropriate for projects based on those sources.
Dope the semiconductor to create a diode. Watch the electrons change position and energy.
Semiconductors are the materials that make modern electronics work. Learn about the basic properties of intrinsic and extrinsic or 'doped' semiconductors with several visualizations. Turn a silicon crystal into an insulator or a conductor, create a depletion region between semiconductors, and explore probability waves of an electron in this interactive activity.
This issue of the free online magazine, Beyond Penguins and Polar Bears, examines how elementary teachers can introduce the Arctic and Antarctica and use science, geography, literacy, and technology to help students compare and contrast these two dramatically different areas as well as their own home.
