Additional Info
  • Make major progress with the goal of trying to complete the lab write-up for the chemical and physical changes lab -- as described on the single sheet handed out with the lab. Be SURE that you have followed the directions carefully -- such as basing your answers on specific observations and data from the lab. You will be allowed to ask Qs in class, and I will collect the lab today OR tomorrow.
  • Be sure to write in complete sentences -- particularly when you are asked to "Explain" or "Justify" your answer.
  • Example of a weak answer: "Iron rusting is a chemical change because it resulted in a new substance."
  • Much better answer: "Iron rusting is an example of a chemical change because the original slivery, metallic iron nail formed a flaky orange-brown solid (probably iron oxide) after the reaction --- demonstrating that the process formed a new substance with new properties.
  • Start studying for quiz on Friday on elements from handout given on the first day of school and posted on Moodle
