Each description of how to conduct the demonstration also includes picturesThis website is a part of the Virtual ChemBookthat includes topics is environmental science. http://www.merlot.org/merlot/viewMaterial.htm?id=393616 This website provides practice for students to gain an understanding of how to balance chemical equations. The tuorial tprovides an explanation if student inputs an error. http://www.merlot.org/merlot/viewMaterial.htm?id=393613 This website contains a collection of excellent chemistry demonstrations that include overal descriptions of the experiment being demonstrated, the chemical concepts being reviewed, safety issues, the step-by-step procedures, questions to ask, a handoout that can be used for student makeups, and excellent movies that show what what happens in the experiment.The materials were developed in conjunction with Robert Becker of Kirkwood High School in Kirkwood, MO. The demonstrations and laboratories are those selected and used by Bob in his classroom. Many of the demonstrations may be assembled in a short time with a limited number of solutions to illustrate a specific point. Some demonstration activities are designated as suitable for either demonstrations or laboratories. If time is short, do a short demonstration with many presentation questions. http://www.merlot.org/merlot/viewMaterial.htm?id=393764 This is a easy to use website that will give you an element and, depending on the selections you make below, you will have to supply the element's chemical name, chemical symbol or atomic number. You type in your answer into the text box and press the 'Check my answer' button. Spelling counts! The website also provides "More options" which you will be able to select whichever elements you want to test yourself on with the flash cards. http://www.merlot.org/merlot/viewMaterial.htm?id=393760 The Mineral Gallary is a browable and searchable website that helps you learn about different charachertistics of minerals.The Mineral Gallery is produced by a commerical company -Amethyst Galleries - which provides the searchable mineral database of significant value to students, educators, and amateur rock collectors. You can purchase minerals on this site as well. http://www.merlot.org/merlot/viewMaterial.htm?id=294382 The periodic table is organized so elements are arranged in columns based on the number of valence (outer) electrons available for chemical reactions. Therefore, the elements in the columns have similar behavior. http://www.merlot.org/merlot/viewMaterial.htm?id=294389 Create three grasshoppers from different sized paper squares. Make a hypothesis as to which grasshopper will "hop" the best. Practice hopping the grasshoppers and then hop each one 5 times. Record the data and figure out which hopped the best. Discuss how you measured "best" i.e., which variables were you measuring to evaluate the hops? List as many variables (things that were different or that changed) as you can... http://www.merlot.org/merlot/viewMaterial.htm?id=294393 Students design their own experiment to answer the burning question "Which food is stickier״? http://www.merlot.org/merlot/viewMaterial.htm?id=294398 Students mix two powders and one liquid in a bag and record observations. Student groups collect information on ten different sets of reactants and share data with whole class. Groups then develop testable questions, design set of experimeints to answer their question, and then determine the answer to the question.
