LARN 006 C2D2

Doing ChemThink interactives are part of the core experiences for all chemistry students.  The objective of working through the Particulate Nature of Matter assignment are to:

Be able to distinguish diagrams of elements, compounds, and mixtures of elements and compounds in the solid, liquid, and gaseous phases of matter and to identify molecules that are composed of atoms of nonmetallic elements that are bound together as a small cluster that move as a unit.

In the ChemThink diagrams a single atom of a particular element will be symbolized by a circle of a certain color and atoms that are joined together as a solid or as a molecule composed of atoms of nonmetallic elements that are bound together as a small cluster that move as a unit are shown as touching.

Start the following ChemThink Particulate Nature of Matter assignment in class:

Click on this link  http://simbucket.com/chemthinkserver/chemthink/, log onto the ChemThink account that you set up on LARN 002 and do the tutorial and question set on Particulate Nature of Matter.  Then do all of the following:

    1. log onto the ChemThink web site and complete both the tutorial and question set. [If the ChemThink is not present on the log on site, find the flash version of the module and use a flash enabled browser to run the module.]
    2. each time you discover the correct response after making an error, record why each correct response is the correct response as part of a list of learnings for this ChemThink module in your Learning Log,
    3. complete the worksheet for the ChemThink interactive.  The worksheet that goes with this module.  is in the packet of worksheets distributed by your teacher.  If not, you can click on this link for the Particulate Nature of Matter module and print one out.
  • NOTE: Be aware that in chemistry a molecule has two definitions: 1) the smallest particle of a gas and 2) a cluster of covalently bonded (usually nonmetallic) elements that are chemically bound together as a small cluster. 
  • The Particulate Nature of Matter module only acknowledges the second definition of a molecule and does not correctly classify a formula unit of a gas containing only one atom as a molecule.  Because this module is incorrectly programmed to mark such a response as incorrect, for purposes of getting beyond questions that ask about molecules, for this module only pretend that a single atom of a gas is not a molecule.

The following information is provided for anyone who wants further assistance or wants to know how ChemThink assignments will be treated in class:

  • Choose menu selections:  The Atom > Particulate Nature of Matter Tutorial.  [If you are logged onto the ChemThink web site, you do this by clicking on the green triangle in the white circle to the right of the displayed module’s name. If you were taken directly to a web page with an orange Tutorial button and a blue Problem Set button, click on the orange Tutorial button.]
  •  If you do not have a copy of the worksheet that goes with this module, you can click on this link for the Particulate Nature of Matter module.  Worksheets for other modules can be found in the Student Resources > Handouts > ChemThink Formative Assessment Note Sheets folder or click on a link to the worksheet if it is provided to take you directly to the document.  Download the worksheet for this particular ChemThink module, and print off a copy.
  • In the upper right corner of the worksheet use a pen to write your hand in number in a circle and your first and last names.
  • Now work your way through the online tutorial.  You will have to answer each problem correctly to advance to the following page. FYI: When there are check boxes given before possible correct responses in either the tutorial or the problem set, more than one response may be correct, so carefully consider each response before submitting your answers.
  • Then choose the menu selections:  The Atom > Particulate Nature of Matter  Question Set to formatively assess the understanding that you have built up by doing the Tutorial.  Focus on understanding why each problem in the question set is answered in the way that it is.  Each time you discover the correct response after making an error, record why each correct response is the correct response as part of a list of learnings for this ChemThink module in your Learning Log,
  • When doing the tutorial you have to answer each problem correctly to advance to the following page.  Your goal is to have a deep enough understanding to obtain a 10 out of 10 score. If you do not attain that level of understanding, review some more, and do the problem set again until you  have mastered the content with a 10 out of 10 score.
  • Record a response to each question asked on the worksheet, place the worksheet in the Notes section of your 3 ring binder and bring it to class.
  • Bring your completed worksheet to class and hand it and your Assignment Tally sheet to your current learning partner. First your learning partner should read your worksheet, discuss his/her understanding of the items with you, and record specific feedback on your paper in dark purple ink.  Your teacher may then ask your learning partner to take your tally sheet, and record the reference designation for the assignment, an abbreviated description of the assignment, the current date, the status of your assignment (using an 0 for incomplete or a check mark, √, for complete), his/her initials signifying that the information recorded is accurate, and return your paper and the tally sheet to you.

The following background information may be helpful to some of you.

  1. To find out which ChemThink module has been assigned, click on the link to the ChemThink module on the mrchemistry. org web site for the current day, or look up the module’s name in your class notes, check for it in a Remind post, or check for it in a new Google Classroom assignment. If the link is unknown to you, search the internet for a link to the named ChemThink module.
  2. For ChemThink modules that are coded in HTML5, the link takes you to a log on screen at the ChemThink web site where your account resides to do the assigned HTML5 module.  [If you do not yet have a ChemThink account, you need to register yourself into the specific section for your chemistry class. If you do not have an account, use this link to access the document explaining how to register for a ChemThink account.  After you have a ChemThink account set up, you can log into that account to do any of the assigned HTML5 modules.
  3. The ChemThink modules that are not on the ChemThink log on site are applications written in the now deprecated Flash programming language.  Flash is no longer supported by the Firefox browser, nor the Chrome browser, nor the Opera browser any longer. You will need a flash enabled browser to run the modules. At present use either an Edge, Internet Explorer, or Safari browser on a laptop or desktop computer to access the mrchemistry.org web site and then click on the link below to take you to the simbucket.com web site.  If the computer asks you whether to allow Flash to run, grant it permission for this module only.
