Properties aren't magic! They are special rules that numbers follow so you can solve problems quickly in your head. Using detailed instructions and rhyming text, students gain understanding of when and how to use mathematical properties. This book will allow students to apply properties of operations as a strategy to add and subtract, or multiply and divide.
Sharpen your pencils and put on your goggles! It's time to see science in action! This book helps readers hone their observation and recording skills during an experiment. Students will learn how to effectively collect and record data in a journal, as well as organizing data using graphs, charts, and diagrams.
Sometimes a hunch isn't enough. Learn how scientists make educated guesses called hypotheses to test their theories. A hypothesis is the foundation of the scientific method. Readers will learn how to construct a measurable and focused hypothesis to test in an experiment.
Science never stops-even when the experiment is complete. Now is the time to make sense of your data. This title teaches young scientists how to analyze, interpret, and communicate the results of their data.
It is essential that scientists design a plan to ensure their experiments are conducted accurately and safely. Readers will learn how to gather materials, and create a step-by-step procedure to test their hypothesis. Readers will become familiar with controls and variables in a scientific setting.
Science engages a curious mind. Questions can come from practically anywhere. Readers will learn why scientists ask questions and how to develop meaningful questions to help guide their scientific experiments.
Science was meant to be shared with others. Scientists must now determine whether or not the data supports their hypothesis. This book illustrates fun and interesting ways in which to report your results, from a science fair demonstration to a written report. Readers are also encouraged to use their results as a springboard for further experimentation.
Its very important for a child to learn how to make good decisions. In this informative new book, Slim Goodbody helps children learn the steps they should follow in making almost any decision: Stop, Think, Act, Review (STAR).
