This is a book for thinkers, students, teachers, and parents who love science and math in the form of activities only using common and basic items. For example you can measure the energy of the sun with a cup of water, a thermometer, and a watch. Each activity gives the purpose, the materials list, the procedure, the data tables, the formulae, and the conclusion to follow. One has to obtain the needed materials, if a student/child have permission and supervision, and a spirit of scientific curiosity to set forth on the adventure of science. All activities involve measurements and calculations to reach conclusions - which is the heart of the scientific method in practice. The range of activities spans most of physics, but looks at chemistry, astronomy, and several types of math too. The slide rule is encouraged ( and a paper template one is supplied ) to do the math with plenty of directions on its use and why it should be used to teach numeracy skills today. To take this quest one has to be the scientist, the researcher, the experimenter, the mathematician - in sum be the inquisitive pioneer.Table of ContentsCh.I Why bring the Slide Rule back to the Classroom today?

This is the second book in the Inquisitive Pioneer journey and is focused on the topics of Electricity & Magnetism in many ways. Though many common items are used as in the first book, there is a need for some electronic items particularly the multi-meter. This book is like the first in that All Activities require data measurement and data analysis. With parental permission and supervision one can make simple batteries, a basic capacitor, a leyden jar, measure a magnetic field, make a basic electric motor, and use solar cells to study them and to use them to study light and the energy of the sun.

This is the 4th volume of The Inquisitive Pioneer series of science and math activities which use primarily basic materials but all involve measurement and calculation to analyze the data. Like all the others in the series there is a paper template slide rule and slide rule use instructions for encouraging numeracy skills. This book acts as the compliment to book one by having a cross-section of activities from the web site: www.cosmicquestthinker.com from which all the books derive. This book has topic areas of conservation of momentum, conservation of mass, Archimedes Principle labs, and many more.

This is the 3rd in the Inquisitive Pioneer series and has the same overall idea with a range of great science activities involving waves and astronomy. Like all in the series the activities are about data measurement and data analysis in using the scientific method in their approach. The slide rule is the suggested and illustrated tool to evaluate your data. Like all books in the series, there is an overall emphasis on low-cost and basic items for doing the activities. However in this book there may be a need to acquire some fun items such as a prism, lenses, and/or a small telescope in one or more of the activities.
