INTRODUCTION

Electrochemistry is the area of chemistry dealing with the interconversion of electrical energy and chemical energy and these processes involves Redox reactions.There are many applications of this in everyday life.Batteries, control of corrosion, metallurgy and electrolysis are just a few examples of the applications of electrochemistry.Redox reactions are used in a wide variety of ways by nature and man. In this assignment you willstudyone area in which they are widely used.

DESCRIPTION OF TASK

For this Culminating Activity you will be in groups of 4. Select one of the categories that uses electrochemistry (chart 1). Choose any one method of presentation (Chart 2) for group discussion. In addition to group discussion, each member of the group is responsible for a personal reflection (2-3 pages) describing

·  How and what Redox reactions are involved in that particular area.

·  Explain their potential impact on society and the environment.

·  Discuss your personal experience working in a group setting, noting strengths and weaknesses.

TASK PERFORMER

To ensure a balance of workload and group work success and, each person in the group is responsible for taking on a role:

·  Checklist MANAGER – reminds group about dates and makes sure that everything is ready on the due dates

·  Personal Reflection MANAGER – makes sure that everyone has completed their personal reflection

·  Questions MANAGER – makes sure that all essential questions are answered during the presentation

·  Production MANAGER – leads brainstorming of ideas, keeps group productive and on task

·  Presentation MANAGER – makes sure that each person is equally involved in the presentation and that the group practices their presentation

Use Project Checklist (Chart 3) to track your progress.

YOUR ASSIGNMENT WILL INCLUDE:

You will present your findings in a classroom in any format you choose. Your classmates in groups of 4-5 will visit your station for 10-15 minutes. You must ensure that your presentation answers the following questions:

1.  Name and describe the topic you choose briefly. Explain its importance in our society.

2.  Rationale why do you choose that particular process.

3.  Explain how electrochemistry works in that process.

4.  Write down the Redox reactions and/or equations behind the process.

5.  What health and safety issues are associated with the techniques used in the process i.e. waste generated, corrosion prevention techniques, toxic substances released to the environment?

6.  What are the potential social, environmental and economic impacts of this process?

7.  Discuss the controversial issues or problems surrounding this electrochemical application and indicate possible solutions.

8.  If your topic is “Metal Implants in Humans” then also reflect upon- Why do metal implants not corrode?

Teacher Notes

This culminating activity involves a combination of cognitive and affective skills resulting in a motivating and enjoyable learning experience. It fosters self-awareness, appreciation and recognition of one's own individual talent or interest, and those of others, while using speaking, listening, acting and viewing, as well as writing. Since students select a topic in which they are already knowledgeable, or have experienced success, the interest level is intrinsic. Positive self-concept and confidence occur as students prepare their speeches and share them with the class, thus working to be effective communicators.

As a teacher, you will need access to computers and S&T notebooks or paper for recording. Teacher should explain each component of Culminating Activity and the Assessment Tools. The Culminating Assignment addresses expectations 1.1, 1.2, 3.5, and 3.6 of the Electrochemistry strand.

A brief introduction of the Culminating Activity and all the concerned safety rules should be discussed the very first day of the unit. The Assessment Progress, Chart 4, shows students the criteria they will be assessed on, and the lessons that allow them to practice those criteria. Teacher should share the culminating assignment rubric with the students which empowered them to take more responsibility for their own learning.

Students are given a Self Assessment Checklist (Chart 5) so that they, as active engaged and critical assessors can make sense of information and masters the skills involved. The teachers should also use the same checklist for each group and follow up with their progress (Chart 6).

Accommodations

·  Students will have a choice regarding what media they want to use, keeping in mind what their individual strengths are.

·  Students with IEP`s will be accommodated on a situation to situation basis.

·  Students will be placed in groups, keeping in mind their strengths and weaknesses.

·  Simplifying the language of procedural writing and handouts.
