We have now started the 2nd Quarter. Due to parent-teacher conferences, Thursday will be a half-day with school letting out at the end of 4th period and there will be no school on Friday. Last Friday, we conducted an experiment to determine whether the following would conduct electricity: tap water, salt, saltwater, sugar, and sugar water. The only one to conduct was saltwater (an ionic solution). Your only homework for the week and the due date are as follows:
Wednesday, Nov. 4: Your assignment is to pick a nontoxic liquid from home (such as orange juice, milk, pickle juice) to test whether it is a conductor of electricity. Monday I will give you a film cannister so that you can transport the liquid from home. Bring in the liquid from home on Wednesday and answer the following questions:
- Is your liquid composed mostly of ionic or covalent bonds?
- Remember, ionic solutions usually conduct electricity, while covalent solutions do not. Based on this information, do you predict that your liquid will conduct electricity?
Wednesday afternoon each student will have the opportunity to test their liquid for conductivity.
Have a great week,
-Mr. Pfiester
