Inquisitive Pioneer Science Activities Volumes 1 And 4.

I am the author and this is my dead name Aka Pen Name - I will sign it in either or both if you wish - tell me in a note when purchasing - also I will include a Pickett 120 plastic Slide Rule which is used in referencing slide rules in the book

1 and 4 are the book ends of this Science Activities series and compliment each other with an awesome cross section of at-home common items and so.e found in local stoes items to learn a great variety of key Science ideas through experimental discovery where one takes measurements and analyzing the data. 

You can buy the whole set of these pen name books here on ebay for 100 whereas these two go together for 70 and on Amazon go for 80-90 dollars with no autograph nor Slide rule.
