Contact info. Chemistry is an incredibly fascinating field of study. Because it is so fundamental to our world, chemistry plays a role in everyone's lives and touches almost every aspect of our existence in some way. Chemistry is essential for meeting our basic needs of food, clothing, shelter, health, energy, and clean air, water, and soil.
Chemical technologies enrich our quality of life in numerous ways by providing new solutions to problems in health, materials, and energy usage. Thus, studying chemistry is useful in preparing us for the real world. Chemistry is often referred to as the central science because it joins together physics and mathematics, biology and medicine, and the earth and environmental sciences.
Knowledge of the nature of chemicals and chemical processes therefore provides insights into a variety of physical and biological phenomena. Knowing something about chemistry is worthwhile because it provides an excellent basis for understanding the physical universe we live in.
For better or for worse, everything is chemical! The UW-La Crosse's accredited Chemistry and Biochemistry programs blend technical, hands-on research experience with practical skill development.
Chemistry : The Central Science. Studying chemistry also puts one in an excellent position to choose from a wide variety of useful, interesting and rewarding careers. Use the search engine to find threads on proportional reasoning. I happen to like Jerry Epstein's posts on this topic the most. Multiple representations of atoms, molecules and bonding patterns confuse chemistry students. So I suggest using two 21st century learning tools to inspire students with the beauty of the molecular world and get them used to seeing in a different way.
Besides animations, students can easily switch between ball and stick, van der Waals and other representations of molecules in motion. Once you load it up, direct your students to the Activity Center, where there is a well-thought out sequence of activities based on Robert Tinker's idea that there are definite visual stepping stones to molecular literacy. One last thing, hands-on activities related to proportional reasoning can be crafted from a challenge to optimize a two component soap bubble formula from soap and water.
I have my students optimize for maximal soap bubble lifetime. They have to vary the ratio between soap and water in order to be successful. Of course, the data has a lot of scatter, but my math colleague teaches them how to perform a statistical analysis to obtain a five number summary through the use of a box plot of the data. If you mix lemonade mix citric acid and baking soda in "just the right" amounts, kids can make a fizzy mix.
If baking soda is in excess it tastes bad! So the goal is to find "just the right" amount. Which of course is a hands-on introduction to the foundational ideas that support proportional reasoning and hopefully transfers to stoichiometery, titration and beyond to pharmceutical formulations and engineering disciplines. BTW: Transfer and application of knowledge from domain to another is a mystery to me and to many others, despite the years of education research.
So despite providing fun and educational proportional reasoning labs, be prepared to acknowledge that individual brain development is one variable that you may have little or no effect on.
I hope this long comment was useful to you. All the best, Greg. Greg, Thank you so much for your well-thought comment. I appreciate it and am honored that my short post got the attention of you, Boris and Frank. I have used the molecular workbench myself and have it on my home computer.
I have not tried asking students to give it a whirl, though; that is something to think about. I look forward to future conversations with you all. Gregory Sir I wholeheartedly appreciate your comment on Why is chemistry hard?
Thank you for all the suggestions If u have any more suggestions Please mail me Gmail: lalakhaling gmail. Why our students refuse to put any effort, should be the title here?! I teach high school math and for the last 10 years, I can see that the main goal for most of my students is to get a good grade without any sweat.
This is an inherently mandated part of any task for a human being. Thinking is what makes us Homo Sapiens. Our students want to learn the Sport of advanced math and science, by simply watching the show. Or the lesson game as it's payed by the teacher. You can't learn to play tennis by simply watching someone playing it. You must get on the field and do the moves. Eventually, you'll get some after a while.
