Dig It!, a third-grade Earth and space science unit, encourages students to investigate humanity’s effects on the environment and the importance of conserving natural resources. The unit builds upon students' prior knowledge and the overarching concept of change by providing opportunities to relate local examples of environmental pollution and conservation with hands-on scientific experiments and demonstrations.

Dig It! was developed by the Center for Gifted Education at The College of William and Mary to offer advanced curriculum supported by years of research. The Center's materials have received national recognition from the United States Department of Education and the National Association for Gifted Children, and they are widely used both nationally and internationally.

Each of the books in this series offers curriculum that focuses on advanced content and higher level processes. The science units contain simulations of real-world problems, and students experience the work of real science by using data-handling skills, analyzing information, and evaluating results. The mathematics units provide sophisticated ideas and concepts, challenging extensions, higher order thinking skills, and opportunities for student exploration based on interest. These materials are a must for any teacher seeking to challenge and engage learners and increase achievement.

Grade 3

I was very disappointed in this book. I was hoping to use it in my homeschool curriculum, but it's clearly made for a classroom setting. Half of the book is rubrics on how to evaluate student work. There are no experiments, and the projects can hardly be called that, they're really just questions posed to students, and they fill out a bunch of worksheets. Nothing hands on, and frankly, very boring.
