My hit science education series: 50 STEM Labs is a great way for kids from elementary to middle school to have fun getting their hands dirty learning key concepts in Science, Technology, Engineering, and Mathematics. 50 Custom Labs allows you to design your own labs in any subject area. It has the table of contents, index, and category pages blank and ready to use. Add your own ideas to the other volumes in the 50 Learning Labs Series Make learning any subject exciting at home and in school PLEASE NOTE: There are no completed labs in this book. It is meant as a companion volume to the series to allow educators to design their own labs, or as a project rubric for teachers.
