Alternating to Direct: Rectifying Alternating Current
Read the Fine Print
Rating
0.0 stars

The Materials Science and Technology Teacher's Workshop (MAST) provides this activity for classes learning about diodes and electrical currents. The laboratory illustrates how diodes can be used to rectify alternating current. It uses a galvanometer to determine the direction of current flow when an AC or DC current is applied to the circuit containing a diode in series with a resistor and a galvanometer.The lesson includes step by step directions for the experiment.The activity should require about 20-30 minutes of class time to complete. Discussion questions and teacher notes are included.

Rating
0.0 stars

In this activity (page 10 of PDF), learners approximate the area of the uppermost cross section of an impact crater using a variety of square grids. They conclude which angle of impact results in the greatest area. There are two versions of this activity: Challenge, where students construct a launcher and create their own craters; and Non-Challenge where students analyze pictures of craters. Includes a pre-lesson activity (p54). The Moon Math: Craters! guide follows a 5E approach, applying concepts of geometry, modeling, data analysis to the NASA lunar spacecraft mission, LCROSS.

Animation of 2006 Ozone Hole
Read the Fine Print
Rating
0.0 stars

The National Oceanic and Atmospheric Administration's (NOAA) polar-obriting satellites monitor the ozone levels around the globe. The ozone layer acts to protect life on Earth by blocking harmful ultraviolet rays from the sun. The "ozone hole" is a severe depletion of the ozone layer high above Antarctica. It is primarily caused by human-produced compounds that release chlorine and bromine gases in the stratosphere. NOAA scientists reported that the 2006 ozone hole in the polar region of the Southern Hemisphere broke records for area and depth. In this animation, the POES satellite sensors document the change in the ozone hole over Antarctica. In the critical layer of the atmosphere between 8 and 13 miles, nearly all of the ozone has been destroyed. However, large declines in the ozone hole, such as the one in 2006, are common year-to-year variations caused by Antarctic stratosphere weather fluctuations. Overall, the ozone hole is estimated to decrease annually very slowly in area by about 0.1 to 0.2 percent for the next 5 to 10 years.

Antibiotic Attack (Kinetic City)
Read the Fine Print
Rating
0.0 stars

This game is a part of the Tau Pack of the Kinetic City site (see description below). In this simulation, the patient's bodies are filled with bacteria. The object is to cure as many patients as possible. Learning concepts enforced here are that antibiotics are specific for the type of bacteria they treat, their strength, and that the bacteria may also become resistant to the bacteria by mutations.KINETIC CITY DESCRIPTION: "Kinetic City" (www.kineticcity.com) is a fun, Web-based after-school science club for kids, ages 8 through 11. It combines exciting online animations and activities with boxes of hands-on science experiments. Children earn "Kinetic City" power points and collect stickers as they complete missions and learn standards-based science content. Here's how it works: The "Kinetic City" super crew (Keisha, Curtis, Megan and Max) needs the help of Earth kids to save their planet Vearth, from the science-distorting computer virus Deep Delete. Each of Deep Delete's 60 hideous strains attacks a different area of science with disastrous consequences. After each attack, teams of Earth kids fight back by viewing a short online animation describing the situation on Vearth; performing a series of activities to re-learn the lost science and going on a mission to Vearth during which they answer science questions and gobble up Deep Delete viruses. Their scores appear on their own Kinetic City Club Web page. "Kinetic City" is produced by the American Association for the Advancement of Science (AAAS), with a grant from the National Science Foundation. AAAS writes the "Project 2061 Benchmarks for Science Literacy," which forms the basis of most state science standards.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth. They will gain perspective on the ways in which human activity continue to strain these resources. Though this was created as a pre-visit activity for a traveling science show, it makes a great stand-alone activity as well!
