Chemistry: exploring the atom, the ion, and isotopes

Since this activity focuses on atoms, ions and isotopes, there will be three activities.  You will finish each activity with your lab group. 

Activity 1 (atoms):   First,  visit http://www.youtube.com/watch?v=TBrJt-5LHgQ (under resources, called youtube video). Watch the video there and then complete the table (electrons worksheet) provided under resources below. 
Next,  Visit http://phet.colorado.edu/.  In the search bar type in Build an atom.  Then click on run in HTML5.  Try all of the activities- atom, symbol and game.
Now, visit http://www.pbs.org/wgbh/nova/physics/periodic-table.html and click on launch interactive. Make sure to experiment with the filters on the left hand side.  Obtain a bag of items from the teacher.  The bag will contain common items you might find around your home, the school, or in a store.  Some of the items are represented in picture form because they were too big or expensive to put in the bag.  Analyze each item for the element or elements they contain.  Remember elements are composed of atoms.  Atoms represent the smallest form of the element that still has all the characteristics of the element.  You can  use the internet, your chemistry book, or any of your group members for this activity.  Fill out the table under resources entitled element grab bag.  Make sure to include as much detail as possible since each person in your group will present one of the elements to the class. For the atomic mass, number, and atomic structure, pick one of the elements found in the item (if there is more than one).

Activity 2 (ions): Visit this website http://www.youtube.com/watch?v=900dXBWgx3Y to learn about ions.  Then complete the worksheet provided below entitled webquest activity for ions. Finally, obtain paper, string and skittles candies from your teacher.  Use these items to build your favorite ion from the worksheet.  As a group, be prepared to share the ion you chose with the class.

Activity 3 (isotopes):  Visit the website http://www.youtube.com/watch?v=EboWeWmh5Pg to watch a video about isotopes.  Then visit http://teachers.oregon.k12.wi.us/sundstrom/Physical%20Science/Atoms%20Periodic%20Table/Isotopes%20Lab.pdf to obtain a copy of the isotope lab.  Use a piece of paper for your group to record your findings-you do not need to print off a copy.  Answer all the questions thoroughly.  Make sure all group members put their names on the lab findings.  Also include a paragraph that summarizes your findings and how it connects with what an isotope is.   Turn this in to the teacher at the end of class time.   If you have time, visit the resource below entitled Heavy water ice.
