Learning Goals for Rotation One
By the end of this rotation I will be able to:
- demonstrate an understanding of trends that atoms demonstrate and how it relates to their placement on the periodic table
- feel gratitude for the scientists before me that did experiments to understand atoms and create and revise the periodic table
- understand the difference between isotopes, radioisotopes and their abundance on the Earth
- maintain a safe lab environment through understanding WHMIS and prepare for labs appropriately
Activity One: Atomic Structure
Please obtain the following reading from Nelson Chemistry 11. Section 1.2 pages 11-16. Read and complete the 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 you will complete the Isotopes and Radioisotopes 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 log into our virtual classroom and complete the WHMIS training. You will need to be safe and understand how chemicals work in a lab before you can start with any labs. Once you have completed this training you will need to take a screen shot of you overall score and submit this picture to the dropbox provided.
Day Two: Lab Work
Please complete the Reactivity Lab. Submit the Observations, Analysis and Evaluation section.
Activity Five: WebQuest - 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. Submit your work to the Elements in the Body dropbox.
Activity Six: Unknown Elements
Please take a look at all these hints and organize the unknown elements into the periodic table. Please submit your final answers.
