In this video segment adapted from NOVA, a geologist digs a trench along the San Andreas Fault to reveal three thousand years of earthquake history. Information from the layers of sediment may help geologists to predict earthquakes.
In this lesson, students will begin measuring with nonstandard units and discover the need for a standard unit of measure. Students will also learn to measure to the nearest inch using an inch ruler correctly and record their results.
Using images and graphs, this interactive resource illustrates scientists' efforts to study Earth's climatic history for the last 250,000 years by drilling into the Greenland Ice Sheet and examining ice cores. Adapted from the Wright Center for Science Education, Tufts University.
Children will work with a partner to measure their hands, feet, and smiles to the nearest inch and centimeter. Children will measure cut slips of different colored construction paper from 1 - 12 inches and graph into even-odd, shortest to longest, longest to shortest. Children will record their information, use the information to solve word problems, and create a number sentence.
Use skittles to help the students practice the concepts of sorting data, recording data, writing the data collected in fraction form (part/whole), changing the fractions into decimals and percents, and taking the data collected and making a spreadsheet, bar graph, and circle graph of the data.
Build a LabVIEW subVI to wait for audio level to exceed a user-defined threshold, and then record audio until the audio level drops below the threshold again.
