Also, when students are sharing they might activate prior knowledge in another student with their contributions. Topics include how images of stars are processed, variable stars identified, and the properties of the variable stars determined. I let students know that they can read aloud or individually, but the point of them being in pairs is to discuss and determine the most important parts of the text. Both sections are worth watching: the first half is on the written exam, while the second half is on the lab practical. Some new technologies enter mainstream use fairly quickly, and the capabilities they offer are often included in new versions of browser software. Students can also explore visualizations independently.
It also gives students an opportunity to visualize the relationship between the sun, earth, moon, and space station. Click the link to go to the plug-in's download page. Once they've opened the document, the students follow the link to the. Students start the activity when they write the word 'ellipse' vertically down the side of a blank sheet of computer paper. Because I know from our introductory activity that my students have a working knowledge of ellipses, students choose a partner and take a computer from the cart at the front of the room. Some students may use this list of viable investigationsto generate their own project ideas, but the teacher should approve allprojects before they are conducted.
Students identify situations that use Kepler's Laws, copy narrative and an image to describe each of the laws, and write example problems with solutions during the activity. A distant view of an observer looking down on earth as well as a perspective of an observer looking into the sky are used in the simulator. In performing these projects, students should have the opportunityto observe change, gather data, record information, and make conclusions aboutthe world around them. Address inquiries to Permissions, McDougal Littell Inc. About Browser Plug-ins What are plug-ins? Using Visualizations Using a projector or video monitor, visualizations can serve as a focal point in class lectures, demonstrations, or discussions. When the Install button appears, click it to install the plug-in into the plug-ins folder of your browser software. Today, the goal is to connect that knowledge with Kepler's Three Laws while still using.
The Pupil's Edition contains blank answer sheets for students to fill in as they follow through the investigations on the Web site. Click the animations to activate them. Earth News provides a weekly summary of Earth science events around the world, and links to organizations that compile Earth and environmental news summaries. Using Data Centers and Local Resources pages These pages can be used as launching points for student research. My announcement and students putting away their computers is how class ends today. Parallax is introduced first, spectroscopic parallax, main sequence fitting, variable stars, and supernova are all discussed.
Click the animations to activate them. Using Investigations Investigations can be used at many stages of instruction. Then, in small groups of two or three, students create a short sentence or phrase that begins with each letter of the vertical word. The descriptions include instructional context suggestions, Key Concepts and Key Skills presented in the investigation, and estimates of the time required for 9th grade students to complete the activity. If you have installation questions or need help troubleshooting visit Macromedia's Support Center. Funding was provided by the National Science Foundation.
Credits see parenthesis following each item : 1. This quick sharing gives me an opportunity to see how much students remember about ellipses and how much they might already know about planetary motion. The Thermal Distribution histogram gives a temperature dependent plot of occupied states for many, many atoms. Investigations have been judged most effective when students worked on them individually or in pairs. I also tell them at this point that if they were not able to finish the simulation questions, the questions are homework.
The array of information offered on each topic encourages students to generate and pursue questions of their own interest. No part of this work may be reproduced or transmitted in any form or by any means, electronic or mechanical, including photocopying and recording, or by any information storage or retrieval system without the prior written permission of McDougal Littell Inc. Then, students work in pairs to read all about Kepler's Three Laws in an. The pages contain background text and questions to help guide students' thinking. Using the Exploring Earth Web Site Interactive Tool Practice The investigations and visualizations on this site were designed to accompany Earth Science, a high school textbook authored by Spaulding and Namowitz and published by McDougal Littell. The first time students are assigned to do an investigation, it may be helpful to walk them through it, displaying the web pages with a projector or a video monitor.
For each investigation, students examine a sequence of Web pages on which they manipulate graphics or interpret image data. I give them about 5 full minutes to work on their creations. Computation of meridional altitude and stellar visibility are also introduced. Go to the Macromedia plug-in test page to check if your browser software has working versions of the plug-ins correctly installed. The investigations aim to help students to think critically, engage deeply, synthesize and evaluate information.
Answers to Investigation Questions are available in the Teacher's Edition of the Internet Investigations Guide. They offer selected links to external Web sites that offer information on focused topics. This site uses Macromedia's Shockwave Player and Flash plug-ins to enhance user interactivity. They have been employed in whole-group settings, in individual and small group work, as homework or extra-credit assignments, and to launch independent research projects. .
Students have the choice to write their answers on a separate sheet of paper or to type and then share their answers electronically. Since students need their written information in the next part of the lesson, I do not collect their work. Click the animations to activate them. This repetition also gives students more opportunities to form and ask questions about various stages of a process. At this website and still in their pairs, students read through the text and use the document to guide them through the process of defining each of Kepler's Laws. Why do red dots appear on some images when I move my cursor over them? If you open a page that indicates an animation or interactive graphic should be there, but the graphic doesn't show up, or the interactivity doesn't work as the directions indicate that it should, try these suggestions: 1.
