Webquest: Dividing the Indivisible, Chemistry Assignments 2

Webquest: Dividing the Indivisible

From 1803 to 1897, scientists continued to discover new elements and explain the behavior of matter in terms of the fundamental, indivisible particles. Like Democritus, Dalton and other scientists of his day agreed that these solid bits of matter could not be divided or cut into any smaller, more fundamental particles. Why should they believe otherwise?Treating atoms as solid bits of matter allowed them to explain a wide range of properties and behaviors of matter.

This understanding changed dramatically in 1897 with the discovery of the first subatomic particle. Complete theWebquest to discover the subatomic particles that were discovered between 1897 and 1932, the stories of how they were discovered, and the names and backgrounds of the people who discovered them.

Journal: Electron Orbitals (Clouds)

What do you think an electron orbital or cloud looks like? Think about the pencil-dropping activity that you did in the Introduction of this unit. What did the target finally look like? Write down your thoughts in your journal and answer the questions there. Please post your journal entry to the Journal: Electron Orbitals (Clouds) assignment link. For information on how this assignment will be graded, please view the grading rubric.

4.01 web quest 

WebQuest: Get To Know the Neighborhood

What do you do when you move into a new neighborhood? You walk around, meet the people on your street, and locate the parks, the movie theaters and other places of interest. In this WebQuest, you will get to know the periodic table and the elements it organizes. You’ll discover:

• Which elements make up the human body?
• Are these the same elements that are abundant in Earth’s crust?
• How are elements on the right side of the periodic table similar to and different from elements on the left side?
• Is there a pattern to these characteristics?
• Are Internet periodic tables the same as ones printed on paper?

Download the WebQuest worksheet and use it to record the information you discover. Submit your completed worksheet to the WebQuest: Get to Know the Neighborhood assignment link for grading. For more information on how this will be graded, please view the WebQuest: Get to Know the Neighborhood rubric.

4.02 WebQuest: Origins of Element Names

Often, when an element symbol doesn’t seem to match its name, the symbol may refer to an older element name that is not used any more. Or the symbol may stand for a word that is not in the English language. Remember, the 118 known chemical elements have been discovered by a variety of people in a range of countries over thousands of years. The wide range of chemical names gives clues to this diversity.

If you discovered a new element, how would you name it? Would you name it after yourself or for the place where the element was found? Would you name it to describe the way the element looked? Maybe you would want to honor a friend, mentor or mythological god by naming the element after that person.

Complete the following WebQuest to discover the origins of several chemical element names. Submit your completed assignment to the WebQuest: Origins of Element Names assignment link for grading. For more information on how this assignment will be graded, please view the WebQuest: Origins of Element Names rubric.

4.04

Project: Ions for your Health

The ions found in sports drinks are not chosen randomly; they are the same ones that are lost from your body when you exercise vigorously. A wide range of ions play critical roles in maintaining health and proper body function. Some of these ions are present in the body in relatively large amounts and some are present only in trace amounts. Other ions can be toxic to humans, even in small amounts.

Follow the directions outlined in the project guide. For this assignment, you will report your findings in a podcast, script, or brochure that includes all the pertinent information. Be creative in your reporting—use this opportunity to "advertise" the importance of these ions to human health.

Submit your completed project to the Project: Ions for Your Health assignment link for grading. For more information on how this assignment will be graded, please view the grading rubric.
