Experimenting is the foundation of science, essential for coming to understand why and how things happen. The activities in this book introduce young, curious minds to the world of scientific experimentation in various fields. Each activity is structured in a similar manner that addresses four questions: What do we want to prove? What materials do we need? How do we do it? and Why and what has occurred? The 28 experiments use basic materials that are easy to find.
