INTRODUCTION

FOSSweb is the interactive multimedia component of the FOSSprogram, which can be accessed via the Internet or the FOSSwebCD-ROM. FOSSweb extends the walls of your classroom to the verylimits of the World Wide Web. FOSSweb is designed to provideenrichment for students and support for teachers, administrators, andfamilies who are actively involved in implementing and enjoyingFOSS materials.

• Students will enjoy the module-specific activities. Studentscan further their science investigations and exercise newskills and knowledge by using the interactive simulationsdesigned for each FOSS module for grades 3–6. They canbring FOSS into their homes and share experiences withtheir families.

• Teachers can seek tips for enhancing specific modules; locateappropriate print, video, and web-based resources; discoverclassroom management ideas; and find informationconcerning plant and animal care.

• Parents can view and download information about FOSSmodules, including module summaries, vocabulary, home/school connections, and resources.

NOTE: FOSSweb is alsoavailable on CD-ROM (partnumber 032-8778) from DeltaEducation. You can order the CDby calling Delta at1-800-258-1302 Monday throughFriday, 8 a.m. to 6 p.m. EST.

GETTING STARTEDFOSSweb is the official site for the inquiry-based FOSS sciencecurriculum. To use FOSSweb, your computer must meet minimumsystem requirements and have a compatible browser and recentversions of several plug-ins. The requirements vary slightly for theFOSS K–2 modules and the FOSS 3–6 modules. Read through thespecifications listed below and install the necessary software so thatyou can view the 3–6 section of the site. Check the FOSSweb technicalinformation page (www.fossweb.com/detector/intro.html)and frequently asked questions (lhsfoss.org/fossweb/faq.html) forupdates to the information provided here.

COMPUTER REQUIREMENTSMacintosh Minimum Requirements. Power Macintosh with 32 MBRAM (64 MB or more recommended), OS 8.6 or later, 16-bit(thousands) color minimum (8-bit will work, but some graphics willnot be properly displayed), monitor resolution of 800 ✕ 600,4X CD-ROM (faster recommended) if running FOSSweb from a CD,an Internet connection if viewing the site on-line.

PC Minimum Requirements. Pentium or 586 120-MHz or equivalent,32 MB of RAM (64 MB recommended), Windows 98 or later, 16-bitcolor video card and monitor (8-bit will work, but some graphics willnot be properly displayed), monitor resolution of 800 ✕ 600,4X CD-ROM (faster recommended) if running FOSSweb from a CD,an Internet connection if viewing the site on-line.

Internet Explorer version 5.0 (for PC) or 5.1(for Mac) or later, or Netscape version 4.7X or later; version 6.2 or laterstrongly recommended, and required on Mac OS X and Windows XP.For Mac users, Safari might be the browser of choice for the future,when Internet Explorer is no longer available for Macs.



WEBSITE

PLUG-IN INSTALLATION AND TESTING YOUR BROWSERTo fully access the grades 3–6 section of FOSSweb, your browser musthave recent versions of the QuickTime, Flash, and Shockwave plug-ins. To determine if your browser has the correct software, click thelink called Test Your Browser/Minimum Requirements for FOSSwebon the FOSSweb homepage (www.fossweb.com/detector/intro.html).Here you can test your browser and install the plug-ins you need.You can also find out about compatible browsers.

RUNNING FOSSWEB FROM THE CD-ROMThe plug-in and system requirements for running FOSSweb from theCD-ROM are the same as for viewing it on-line. To start FOSSwebfrom the CD, click the FOSSweb.html file. It will open in yourcomputer’s default browser. Click the link called Test Your Browserto determine if you have the necessary plug-ins. The plug-ins are onthe CD-ROM, or you can also download them from the Internet.Internet versions may be more up-to-date. For more informationrefer to the Read Me file on the CD-ROM.

If you are running FOSSweb from the CD-ROM and you click on awebsite, the browser will attempt to look up the page through theInternet. If you’re off-line, you’ll get an alert box, telling you thatFOSSweb cannot find the page.

INTERNET REQUIREMENTSYou will need a modem that runs at 28.8 kilobytes per second or faster(128 kbps or faster direct Internet connection recommended).Activities may take up to 3 minutes to load the first time with a 28.8kbps modem.

PRINTINGYou can print all pages on FOSSweb except the Shockwave activities.In all cases, the center frame is printed without the top and side menubars.

NOTE: If you are using Internet Explorer 4.0 on a PC, you must pressControl P to print. Version 4.0 is below our minimum specifications,and we do not support it. We strongly recommend using version 5.0or later.




MIXTURES AND SOLUTIONS MODULEOn the Welcome page, click Preview under the grades 3–6 flag to see abrief overview of the 3–6 site.

Click the grades 3–6 icon to get a menu that links to each of the 3–6modules. There you can choose Mixtures and Solutions and travel toa wealth of information and activities specific to that module forstudents, parents, and teachers. The section for students has aninteractive activity, project posters, pictures, movies, websites, avocabulary list, a list of books and software, and an “Ask a Scientist”section. Parents and teachers can go to a module summary, a link tohome/school connections, resources, and tips and tricks for usingFOSS in the classroom.

If possible, introduce FOSSweb to students using a computerconnected to a large monitor or digital projector. After a groupintroduction, move students to the computer lab or to computerstations in your classroom. Students in grades 3–6 need to have afocus when they begin exploring FOSSweb on their own or in small

groups. Consider using some of the following questions and ideasto get them started. You can allow more free exploration oncestudents have learned how to use FOSSweb and have completedsome introductory assignments.

In Mixtures and Solutions, you’ll find an activity called JunkyardAnalysis. Introduce this activity after students have completedInvestigation 1, Separating Mixtures. Students dig up items in ajunkyard and decide whether the item will create a mixture orsolution when added to water. You might ask,

• What is a mixture?

• What is a solution?

• What are some of the mixtures and solutions we have investigated?



WEBSITE

Review the introductory screen with the class. Click anywhere on thescreen to move to the activity. Click the bulldozer. An item willappear in the bulldozer’s shovel. Click and drag the item to thejunkyard analyzer. If you get stuck while dragging the item, releasethe item and try again. Once the item is analyzed, click the Dunkbutton to see if the object dissolves in water. As a class, decidewhether the object will dissolve and choose either Solution or Mixture.Before students try the activity on their own, you might suggest theydo one or more of the following:

• Make a list of the most common elements in all the objects.

• Make different categories of the objects using different reasons:objects that contain carbon, objects that contain iron, objects thatare or were part of living things (fishbone, spinach, rice).

• Record the composition of each object.

Then use their records for class discussion. Ask,

• What do you notice when you compare the compositions?

In Posters, students can view summaries of investigations or posterscreated by students as part of the end-of-module project. Students canalso submit their own project posters to share with other FOSSlearners.

Pictures include images of different aspects of chemistry. Studentsmay want to do further research starting with these pictures as part oftheir end-of-module project.

Movies include a chemist explaining the difference between physicaland chemical changes.

Websites include links to sites that can extend student experience withthe Mixtures and Solutions Module. The links may inspire somenew projects and investigations involving mixtures and solutions.

In Vocabulary, students will find a glossary of words used in theMixtures and Solutions Module investigations and in FOSS ScienceStories: Mixtures and Solutions. Downloadable pdf files of thevocabulary list and glossary are available here.

Books/Software includes an annotated list of books, videos, andsoftware recommended for the Mixtures and Solutions Module.

In Ask a Scientist, students can review questions about chemistry thathave been submitted by other students and ask appropriate questionsof their own. Adult guidance in submitting questions is highlyrecommended.
