Learning Goals

Through this rotation we will be able to:

  • Investigate physical and chemical properties of elements and compounds.
  • Demonstrate an understanding of trends in the periodic table such as radius, electronegativity etc.
  • Analyse the properties of commonly used chemical substances and their effects on human health and the environment and propose ways to lessen their impact.
  • Apply knowledge and understanding of safe laboratory practices and procedures (including WHMIS symbols).
Activity One: Atomic Structure

Please obtain the following reading from Nelson Chemistry 11.  Section 1.2 pages 11-16 (1-2 Atomic Structure Reading).  Read and complete the 1.2 atomic structure worksheet and questions.  These pages will be used by others so take care with them!  You will submit the worksheet and additional questions.

Activity Two: Isotopes and Radioisotopes

You will watch the two short video clips.  You can (and probably should) take some jot notes.  Next complete the  1.4 Isotopes, Radioisotopes, and Atomic Mass Reading will complete the 1.4 – worksheet and do questions.  You will submit any jot notes, the worksheet and questions.

Activity Three: Graphing the Trends

The Periodic Table is arranged according to Periodic Law. The Periodic Law states that when elements are arranged in order of increasing atomic number, their physical and chemical properties show a periodic pattern. These patterns can be discovered by examining the changes in properties of elements on the Periodic Table. The properties that will be examined in this lesson are: atomic size, ionic radius, electronegativity, and ionization energy.

You will be creating 4 graphs using the data set and using those graphs to answer question about what trends you see.  You will submit your graphs and answers.

Graphing Tips: A graph must always:

  • Have a great title – that explains what the data is (not simply ‘Time vs Distance’ for example)
  • Have identified x and y axis
  • Have units indicated on each axis
  • Be of adequate size
  • Include a legend if more than one set of results (line) is being graphed
  • Have points on the graph “linked” in some way, either by joining all the points, or by drawing best fit line.
  • Be made on graph paper or with computer software
Activity Four: WHMIS and Reactivity Lab

Day One: WHMIS and Prelab Work

Please complete the WHMIS worksheet.  Also read through the Lab Safety information pages.

You will need to be safe and understand how chemicals work in a lab before you can start with any labs.  

Day Two: Lab Work

Please complete the Reactivity Lab.  Submit the Observations, Analysis and Evaluation section.

Activity Five: Elements in the Body

Many food manufactures add sulfites to thier products.  You will be looking at assessing its potential benefits or harms to the human body.  You will determine (with proof) for yourself if sulfites should be added to our food.  You will include a list of references that you use to determine this and can refer to them in your write up.

Please put your in the comment section below (it will go into review before posting).

Activity Six: Unknown Elements

Please take a look at all these hints and organize the unknown elements into the periodic table (Periodic Law Puzzle worksheet).  Please submit your final answers.
