Physical and Chemical Changes - Making Toffee

Fourth graders make toffee to observe both physical and chemical changes. They determine what types of changes that are caused by the cooking process and which are chemical, and which are physical. In order to do this they follow a recipe, mix ingredients, cook them, pour them into a pan making observations throughout the process.

Hi, I was recently hired as a middle school science teacher in Newark, NJ. I received a call on a Friday and was asked to begin the following Monday. As a new teacher, and with only 3 days to prepare, I was really feeling the pressure. The school requires 2 weeks of lesson plans every Sunday, so I began searching the web for help. Thank goodness I found Lesson Planet. I still use the site everyday to form great lessons and activities for the kids.
