LHS Physical Science

November 12, 2013

           The students taking Physical Science with Mr. Benge have been studying the basics of how chemical reactions work.   In each chapter the students have been learning how to use individual skills and techniques in order to better understand and predict how a chemical reaction will occur.  They have learned how to name chemical compounds, as well as, writing the appropriate chemical formulas when given a compound's name; balance chemical equations; and identify the difference between chemical and physical changes.

            In a few labs and demonstrations, the students learned that everyday household items are often involved in chemical reactions.  For example, the students learned that by adding vinegar to a baking soda solution, they could make a homemade volcano model.  By understanding how substances react with each other they will be able to protect themselves from any harmful reactions.

            The Physical Science students are working very hard so far this year and are doing very well.  I feel that they have gained some valuable knowledge that they will be able to use in their lives outside of school.  I anticipate more success for each class and I look forward to meeting all of the parents of these students at parent teacher conferences later this semester.
