Product description:

★ fast learning method of fingerprint.

★ by fingerprint acquisition， fingerprint feature their own understanding.

★ fingerprint identification of each person， each person's fingerprints are not the same.

■ through fingerprint acquisition， fingerprint interest triggered by small friends， learn simple knowledge aboutfingerprint; ability to actual operation to solve the problem of cultivating children.

■ because each stripe fingers were covered in sweat glands and pores， sweat from these pores， accumulated to a certain number of will whole covered ridge. Therefore， when we come into contact with an object， finger ridge wholeprofile， in an invisible sweat precipitate， retained on an object's surface. According to studies， form grain distributionof each finger of each person is different， and the grain shape in life are kept fixed， even the twins， their fingerprints are not the same. Therefore， the fingerprint is often used for identification， even as the police suspect arresteffective evidence of conviction.

■ exploratory boy is exploration， he is not a simple science， but involves a variety of subjects， such as physics，chemistry， astronomy， mathematics， and its visualization， modeling， standardization.

Objective is to commence from the interest， find the children's interest in learning， so as to effectively guide， finallylet the children interested in learning. Objective is to commence from the interest， find the children's interest in learning， so as to effectively guide， finally let the children interested in learning. To feel the real world with thescientific thought of splendid， the virtual world and let the children stay away from computer games.
