Preparation of chalcone derivatives
Lesson Plan out line:
Preparation of chalcone derivatives
Course:
10, 12 grades regents Chemistry and A.P. Chemistry
Objective:
Student develops and caries out a research project.
Student discusses the characteristics of organic compounds. [9-12 Content Standard B- Structure and properties of matter]
Student identifies homologous series of hydrocarbons by structure.
Student identifies simple alcohols, aldehydes, organic acids, esters, ethers, amino acids and proteins by structure.
Student predicts outcome of organic reactions. [9-12 Content Standard B- Chemical reactions]
Student demonstrates ability to determine the characteristics of an unknown solution using a schematics system of analysis.[9-12 Content Standard A- Abilities necessary to do scientific inquiry]
In laboratory exercise student will investigate some of the properties of a pair of cis - trans isomers.
Student collects common organic compounds at home, reports effects of a pesticide.
In laboratory exercise student identifies qualitative separation of silver, lead and mercury ions, and determines which unknown ion is in his solution. Write out equation for precipitation of metallic ions.
Motivation:
Hands-on learning experiences with manipulative in science classes accomplishes the following;
Emphasizes the role of the student as an active learner.
Merges instructional and assessment activities.
Promotes a vision of science that goes beyond correct answers.
Encourages students to communicate their understandings of science.
Supports a developmental approach to learning.
Fosters the view of the student as a developing scientist of his or her own knowledge.
Teachers should be doing everything in our power to help our students gain knowledge, skills and understanding of their responsibilities as citizens of this country. It is of course our chosen responsibility and moral obligation as professional educators to make sure our pupils are educationally literate and prepared, to the best of our ability, to assume their rightful places as future leaders of society.
A teacher is an important role model for his or her students and can potentially have a large degree of influence upon the future career choices and accomplishments of that persons students.
Development:
We discuss what is involved in being a researcher.
Introduce mass spectrometry. [9-12 Content Standard E- Understandings about science and technology] Homework;
Read mass spectrometry information and answer a few questions about how a mass
spectrometer works and how it is used. Assignments are due the following school day.
Review mass spectrometry assignments and answer questions / confusions students may have, then go into more detail about how to read a mass spectrum and how they are used to identify chemicals.
Identify the potential problem, define and represent the problem, explore possible strategies. Act on those strategies, look back and evaluate the results.
