Automatic PDF and Printable Page buttons
Use the Print and PDF buttons to make clean printable pages or PDFs, respectively. PDFs make e-mail and web sharing more than easy. Printable pages are convenient for taking on-the-go, especially away from internet or computer access.
This is very useful for printing handouts or additional references for use in class. It is also useful for the lesson planner who prefers to have all materials laid out visually during the planning process.
Links to NSES, AAAS, and Wisconsin MAS science standards
Click once on "Science Standards" to see what standards this lesson might meet. Standards are from National Academy of Sciences (National Science Education Standards), American Association for the Advancement of Science (Project 2061 Benchmarks for Science Literacy), and Wisconsin Department of Public Instruction (Model Academic Standards for Science). Standards are also cross-listed, so clicking on a particular standard will display all other lessons that meet that standard.
This is especially useful for schools with standards-based instruction and/or assessment.
Multiple definitions and mathematical representations
Click each tab under Concept Definition to see a brief definition of the main concept of the lesson. The definitions are written for several different levels of student comprehension.
This is useful for the student who needs a quick refresher or for the teacher who finds the best explanation has momentarily slipped the mind.
Vocabulary with pop-up definitions
Within the "Important Vocabulary" slide, there are several words that might be used in regard to this lesson. Move the mouse over each word for a definition pop-up. Move the mouse away from the word, and the definition will disappear again.
This is very useful for writing assessment questions or for teaching students how to use the wording of a question to identify the concept needed.
Automatic bookmark link
Use the BOOKMARK button at the bottom of each page to quickly add the lesson to any one of almost three hundred social networks or social bookmarking sites.
This is useful for managing multiple online resources at the same time without pausing to write each citation on a notecard.
Cross-listed glossary to show everywhere a term is used
Access the Glossary from the left-hand "Main Menu." Once inside, click "Search" next to a term to see all lessons where that term is listed as "Important Vocabulary."
This is very useful when a student has an assessment question, and the use of the Internet is allowed. The student can find the terms used in the question phrasing and quickly determine which concept is needed.
Demonstration guided observation worksheet (only under Charles' Law now)
Click the PDF link to download a ready-to-print guided demonstration observation worksheet. Otherwise, use the DOCX link to download a Microsoft Word XML Document, which can be edited as much as necessary for use in the classroom.
Students requiring adaptations to gain the full benefit of a demonstration may find a worksheet with guided observations useful. Alternatively, a teacher may wish to use a worksheet with guided observations to model what observations all students should be making during a demonstration.
Automatic PDF and Printable Page buttons for a demonstration (only under Charles' Law now)
Click the Print or PDF buttons in each Demonstration to access cleanly printable pages or neat PDFs, respectively, for just this demonstration.
Printing a demonstration is especially useful when the demonstration requires the use of chemicals, tools, or methods that might damage a computer. It is also helpful to have a single page with materials needed, rather than a whole computer, when accessing a chemical storeroom.
For registered users, Favorite Demonstrations (only under Charles' Law now)
Click and add any demonstration to "My Saved Demos" to quickly and easily access only the demonstrations you like best.
This will be useful for a teacher who uses limited demonstrations, but uses them frequently or regularly.
