Student Seismosurfing Ideas 4. Guide to Activities 5. Resources 1. Introduction "Earthquake!" is a collection of lessons, activities, research ideas, and resource suggestions on the subject of earthquakes. The material in this set of lessons is only a sampling of the many activities that can be done on the subject of earthquakes. Most earth science textbooks discuss the subject, and many supplementary resources have been produced by independent groups and government agencies, such as the United States Geological Survey. A few of these resources are listed under Resources near the end of this teacher section. "Earthquake!" integrates a wide variety of physical science topics, including energy, waves, the interior and surface of the earth, and more. How should I use these lessons? Although many of the lessons and activities will need teacher guidance, "Earthquake!" has been written for the student user. These lessons can be used in a variety of ways: * Students sit at the computer terminal and work through the lessons individually. The teacher guides students, trouble-shoots problems, and/or directs which activities the students are required to do. * Teacher uses one terminal and/or a screen projection system to display specific lessons, charts, media bites, etc. to a group of students who are not at individual terminals. * Teacher prints out hard (paper) copies of specific lessons, charts, etc. and assigns them to students. Students do not need computers. Who is the student audience for these lessons? The lessons in "Earthquake!" can be done by a variety of students of various ages, skills, and knowledge backgrounds. Though many of the specific activities are designed with the junior-senior high school science student in mind, even elementary students or those with no science background can find some information, activities, and pictures of interest. High school physics students will learn quantitatively about seismic waves, and 6th grade science students can learn how to make their own home-made seismograph. Teachers should introduce students to the computer terminals that the students will be using. Many of the activities involve specific skills (e.g. plotting data on a graph) or knowledge (e.g. transverse and compressional waves); students will find such activities more understandable if these ideas are reviewed beforehand. 2.

A map is a representation of the Earth, or part of it. The distinctive characteristic of a topographic map is that the shape of the Earth's surface is shown by contour lines. Contours are imaginary lines that join points of equal elevation on the surface of the land above or below a reference surface, such as mean sea level. Contours make it possible to measure the height of mountains, depths of the ocean bottom, and steepness of slopes. A topographic map shows more than contours. The map includes symbols that represent such features as streets, buildings, streams, and vegetation. These symbols are constantly refined to better relate to the features they represent, improve the appearance or readability of the map, or reduce production cost. Consequently, within the same series, maps may have slightly different symbols for the same feature. Examples of symbols that have changed include built-up areas, roads, intermittent drainage, and some lettering styles. On one type of large-scale topographic map, called provisional, some symbols and lettering are handdrawn. Reading Topographic Maps Interpreting the colored lines, areas, and other symbols is the first step in using topographic maps. Features are shown as points, lines, or areas, depending on their size and extent. For example, individual houses may be shown as small black squares. For larger buildings, the actual shapes are mapped. In densely built-up areas, most individual buildings are omitted and an area tint is shown. On some maps, post offices, churches, city halls, and other landmark buildings are shown within the tinted area. The first features usually noticed on a topographic map are the area features, such as vegetation (green), water (blue), and densely built-up areas (gray or red). Many features are shown by lines that may be straight, curved, solid, dashed, dotted, or in any combination. The colors of the lines usually indicate similar classes of information: topographic contours (brown); lakes, streams, irrigation ditches, and other hydrographic features (blue); land grids and important roads (red); and other roads and trails, railroads, boundaries, and other cultural features (black). At one time, purple was used as a revision color to show all feature changes. Currently, purple is not used in our revision program, but purple features are still present on many existing maps. Various point symbols are used to depict features such as buildings, campgrounds, springs, water tanks, mines, survey control points, and wells. Names of places and features are shown in a color corresponding to the type of feature. Many features are identified by 205 text/html 2008-11-26T14:37:24+00:00 Topographic Map Symbols ...

They will understand that objects cannot move unless a force is applied to them. Force also is needed to make an object slow down, speed up, or change direction. Students will explore the various types of force such as gravitational and magnetic. Students will observe that natural forces shape the surface of the Earth, such as plate movement, water, wind and ice (glaciers), causing earthquakes and landforms. In addition, students will discover that work is done whenever a force moves an object through a distance. Building on knowledge and vocabulary taught in 1st grade, students will see how simple machines make work easier. Students will conduct experiments testing the application of force and motion using simple machines and compound machines. Unit Description Observe that the weight of an object, the intensity of the push or pull, and friction are factors that affect the motion of an object. Discuss Sir Isaac Newton and his Three Laws of Motion Understand that the mass of an object is constant whereas the weight of an object can change due to gravity (For instance, your weight on the Moon would be approximately one sixth of your weight on earth due to the effect of gravity). Test and observe how natural forces shape the surface of the Earth. Test various types of friction, and how it causes an object to slow or stop. Identify simple machines as machines with few or no moving parts. Simple machines make work easier. In order for simple machines to do work for us, we have to apply a force on it. Manipulate, use and build a variety of simple machines including levers, gears, inclined planes, wedges, screws, pulleys, wheels and axles. Identify parts of simple machines and how one part connects to and affects another. Manipulate, predict, observe and record the effects of removing or changing parts using a variety of dissectible or rearrangeable simple machines. Identify everyday simple machines based on their parts and characteristics. Test how simple machines increase the ability to extend distance and increase speed with less effort. In addition to using simple machines, use a variety of measurement tools such as the spring scale, meter stick, meter roller, and balance scales. Vocabulary Words force friction gravity inertia magnetism pole work simple machine compound machine lever fulcrum inclined plane screw wedge pulley gear wheel and axle motion (kinetic energy is the energy of motion) distance direction resting position push pull parts of a system Sir Isaac Newton Laws of Motion Guiding Questions Throughout this unit, students should have the opportunity to discuss a variety of higher level questions. Through their experiences during this unit of study, students should be able to successfully answer these questions: 737 text/html 2009-04-17T18:48:12+00:00 ...

This lesson is done in an hour and a half and is intended for third grade. Purpose: The student will be able to observe and describe insects' camouflage techniques in their different habitats. The students will be able to duplicate their environment in the classroom using collected materials. The TEKS that are used are: 3.1 Field and Laboratory Investigations: a. demonstrate safe practices during field and laboratory investigations. 3.2 Scientific Inquiry: Field and Laboratory: b. collect information: observe and measure. 3.9 Adaptations Increase Survival of Species: a. observe and identify characteristics that allow survival. b. analyze adaptive characteristics. Materials: 5 shoe boxes 5 collecting jars 5 nets 5 aspirators drawing paper for each student Getting Ready: Explain to the class that camouflage is used by insects so that they can hide from their predators and so they can surprise their prey. Motivate: Hide pictures of different insects around the classroom and ask the students to find all of them. Ask them why some of them were so difficult to find. Reinforce the idea of camouflage here. Activity: Take the students outside and show the them how to use the collection pieces properly. Then, put the students into groups and put them into groups of four. Give each group a net, aspirator, jar, and shoe box. Have each group collect one insect and put some of its habitat into the shoe box. Make sure each student has a job in the group(insect collector, habitat collector, secretary and time keeper). After each group is finished take them back to the classroom and have each group show their shoe box to the class and explain what they discovered. The instructor and classmates will ask questions about each groups' collection. Safety Tips: Make sure the students use the equipment properly and do not pick up the insects with their hand as the students may be bitten or stung. Concept Discovery: Explain the concept of camouflage again and recap how each of the groups' insects use camouflage in order to survive. Going Further: Talk about how people use camouflage in war and to conceal things such as putting a house key in a rock to hide it from others. Closure: Close the lesson by asking the students questions about camouflage. Also, ask them to ask you questions that they may have. Assessment: In order to assess the students they will individually draw a picture of an example of camouflage, write the insects name, its habitat, and why it is where it is under the picture. The project will be graded on a four point scale(A=4, B=3, C=2, D=1, F=O). Each missing part is a point off. Connection: This activity could be connected to mathematics by counting the number of spots on ladybird beetles or how many insects are in a habitat. For language arts you could have the students write an essay pretending they 737 text/html 2009-04-17T18:49:32+00:00 Texas A&M University, Department of Entomology, lesson plans for teachers, insects ...
