Chemistry 1.4 1.4 Chemistry

Problem Solving in Chemistry 1.4 Shape-sorter toys fascinate young children. Typically, the children try placing a shape in different holes until they find the right one. The trial-and-error approach is one method of problem solving, but it is usually not the best one.

Skills Used in Solving Problems 1.4 Skills Used in Solving Problems Skills Used in Solving Problems What is a general approach to solving a problem?

Skills Used in Solving Problems 1.4 Skills Used in Solving Problems Effective problem solving always involves developing a plan and then implementing that plan.

Skills Used in Solving Problems 1.4 Skills Used in Solving Problems Shopping involves problem solving skills. A shopper must make many decision. Some of those decisions are based on data, like the information on a food label.

Solving Numeric Problems 1.4 Solving Numeric Problems Solving Numeric Problems What are the three steps for solving numeric problems?

Solving Numeric Problems 1.4 Solving Numeric Problems The steps for solving a numeric word problem are analyze, calculate, and evaluate. This flowchart summarizes the steps for solving a numeric problem. Predicting In which step do you make a plan for getting from what is known to what is unknown?

Solving Numeric Problems 1.4 Solving Numeric Problems Analyze To solve a word problem, you must first determine where you are starting from (identify what is known) and where you are going (identify the unknown). After you identify the known and the unknown, you need to make a plan for getting from the known to the unknown.

Solving Numeric Problems 1.4 Solving Numeric Problems Calculate If you make an effective plan, doing the calculations is usually the easiest part of the process. Evaluate Check that your answer is reasonable and makes sense. Check that it has the correct unit and the correct number of significant figures.
