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...
Curated OER
HOW IS PH DETERMINED?
Students estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.
