Preface：

Today, with an increasing emphasis on children's education，Enlightenment education has gradually become an important topic pursued and explored in the field of education today。More and more teachers and parents are beginning to pay attention to cultivating children's qualities from an early age，Help children develop good character and behavioral habits from the very beginning。Parent-child interactive handicrafts can enhance the quality of parent-child companionship，Improve parent-child relationships，The time we spend with our children，No mobile phone、ipad、Television，Only joy，Interaction and communication。 It can cultivate children's ability to solve problems by themselves when they encounter problems，Children should first see and experience the solution by themselves，Because this is how my parents and teachers solve problems while doing handicrafts。 It can develop children's imagination，In a child's world，Cars can fly in the sky、The sun can be green...... Play handicraftsDIYChildren's hands-on ability can be cultivated by using different tools，The child's little hands got sufficient exercise。Brush、Pigment、Scissors、Hot-melt gun、Glue.....，Dare to try any tool，It is also developing different skills to a certain extent。 A child's self-confidence lies in the process of handicrafts，Let's try every possible way together，Have experienced many failures，But it always succeeds，To a certain extent, it enhanced his self-confidence。 Cultivate children's concentration when they are exploring various tools and handicrafts，He is very focused，If there is no external disturbance，He can keep exploring。

Experimental purpose：Entertain through games，Let children acquire more knowledge and develop their own hands-on abilities。

Principle application："Holographic"Projection是近年来盛行的立体Projection技术，It is a method that uses the principles of interference and diffraction to record and reproduce the true three-dimensional image of an object，Audience members do not need to wear them3DA three-dimensional virtual scene can be seen through glasses。

Experimental cognition：The interference principle is used to record the light wave information of the object，This is the shooting process：The subject forms a diffused object beam under laser irradiation

Knowledge expansion：激光作为参考光束射到"Holographic"底片上，Interference occurs when the light beam of an object is superimposed，Convert the phase and amplitude of each point on the object's light wave into intensity that varies in space，Thus, all the information of the object's light waves is recorded by using the contrast and intervals between the interference fringes

Knowledge extension：同学们可以利用现有资源自己动手制作一个"Holographic"3DProjection.
