This is a laboratory based assignment that is for Introductory level geoscience classes (Physical Geology, Historical Geology, Earth Science) that brings an authentic research experience to your students. In the assignment, students are asked to process and interpret screenwash from the 2004 Aurora Mastodont Project, and to contribute authentic research results to the ongoing post-dig analyses. Students then contribute their results to a database to compare theirs to their colleagues around the country. This is an ongoing and free exercise available by requesting samples of screenwash (details below). This is one of several exercises that I ask my Earth Science students to complete as an introduction to the nature of science and the geosciences, that I call GSI (GeoScience Investigations) which was presented as a poster during the 2013 GSA in Denver.

In this lesson, students will demonstrate their understanding of the aurora by writing their own poems. Teachers can decide which form(s) of poetry to use from their worksheets or allow students to create their own. Examples of styles include: Acrostic, List, Haiku, Like and As, and May and Could. To help students get inspired, the class will read a poem on the aurora, and they can also look through their portfolios to help form ideas. Includes teacher notes and instructions, student workshops and an online, animated story, and related teacher resources on aurora. This is lesson five of a collection of five activities that can be used individually or as a sequence; concludes with a KWL (Know/Want-to-know/Learned) assessment activity.

This is a laboratory activity in which students will compare the amount of carbon dioxide in four different sources of gas and determine the carbon dioxide contribution from automobiles. They test ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide from a vinegar/baking soda mixture.

What starts out as a cascade of well-mixed granular materials sorts itself into alternating layers of salt and sand.

This Western Mining History database uses Mineral Resources Data System to list known Colorado historical mines by county. Each county site has links to the known mines within its borders. Some are known and named, others are unnamed. Mines should be assumed to be on private property unless other research is conducted. Data provided for each mine site include: Name, State, County, Elevation, Primary Mineral Mined, Latitude and Longitude and a link to Google Maps. Photos are provided where available. Additional information for some Mines are satellite photos, and ownership, business and historical records. Mining History is an historical site that provides information on mining, mining towns, the gold and silver rush, and Photos and maps of the western United States. This is a great database for student historical research or data and statistics classes. Consider becoming a member or making a donation to help further the work of the site.

Students are introduced to the concept of engineering biological organisms and studying their growth to be able to identify periods of fast and slow growth. They learn that bacteria are found everywhere, including on the surfaces of our hands. Student groups study three different conditions under which bacteria are found and compare the growth of the individual bacteria from each source. In addition to monitoring the quantity of bacteria from differ conditions, they record the growth of bacteria over time, which is an excellent tool to study binary fission and the reproduction of unicellular organisms.

The Center for Food Safety and Applied Nutrition (CFSAN) prepared this online handbook on foodborne pathogenic microorganisms (bacteria, viruses and parasites) and natural toxins. Chapters are arranged under the following headings: Pathogenic Bacteria, Enterovirulent Escherichia Coli Group, Parasitic Protozoa and Worms, Viruses, Natural Toxins, Other Pathogenic Agents, and Appendices. The intent of each chapter is to provide basic facts regarding these organisms and toxins including their characteristics, habitat or source, associated foods, infective dose, characteristic disease symptoms, complications, recent and/or major outbreaks, and any susceptible populations. The chapters also contain minimal information on the analytical methods used to detect, isolate, and/or identify the pathogens or natural toxins.

In this experiment, two chemicals that can be found around the house will be mixed within a plastic baggie, and several chemical changes will be observed.

In this video, NOAA's Deke Arndt, Chief of the Climate Monitoring Branch at the National Climatic Data Center, recaps the temperature and precipitation data for the continental US in summer 2012. It describes how these conditions have led to drought and reduced crop yields.

This video lecture presents the basic definitions of assets, liabilities and equity with simple examples. It also explains the concept of accounting equation with examples.

Video lesson intended for grades 3-5 with a mindfulness moment, warmup, instruction and practice of basic balance and transfer of weight movements, and a sequence of two movements. Video is 15:48 minutes in length.Video created by Virginia's Chief Movement Officers cadre in collaboration with Focused Fitness, Virginia Department of Health, and Virginia Department of Education.

In this lesson students will learn that the food they are eating contain a variety of things such as nutrients, vitamins, fats, and sugars.

This lecture/activity on force will further a students' understanding of forces on an object, as well as the difference between a balanced and unbalanced forces.

Play with objects on a teeter totter to learn about balance. Test what you've learned by trying the Balance Challenge game.

This webpage from Exploratorium provides an activity that demonstrates the Bernoulli principle with readily available materials. In this activity a table tennis ball is levitated in a stream of air from a vacuum cleaner. The site provides an explanation of what happens, asks questions about the activity, and also describes applications to flight. This activity is part of Exploratorium's Science Snacks series.

How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!

In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it. Learners discover it is easier to balance a wooden dowel on the tip of their fingers when a lump of clay is near the top of the stick. Use this activity to introduce learners to rotational inertia.

The simulation shows a ballistics cart. If the cart is at rest on a horizontal surface, it will shoot a ball straight up in the air, and catch the ball again. What if, as in this simulation, the cart is traveling at a constant velocity horizontally, instead? Will the ball land ahead of the cart, in the cart, or behind the cart? Note that the cart fires the ball straight up, with respect to the cart, when the middle of the cart passes the small vertical trigger on the track.
Use the buttons to select the different modes (whether there is a tunnel or not, and whether to show the velocity vectors).
