Answer the questions and face science fairs without fear with help from the Science Fair Warm-Up series. The teachers guide lets you make best use of the original investigations and problem-solving exercises provided by each of the grade-appropriate student editions. The Science Fair Warm-Up series consists of three books; each book builds on the ideas introduced in the previous book, and the problems in the later books are progressively more challenging. The series' field-tested material will help your students develop the inquiry skills to carry their projects through whether they're middle schoolers preparing for their first science fair or high schoolers ready for very challenging investigations.
