Preface：

Today, with an increasing emphasis on children's education，Scientific enlightenment education has gradually become an important topic pursued and explored in the field of education nowadays。More and more teachers and parents are beginning to pay attention to cultivating children's scientific literacy from an early age，Help children develop good character and behavioral habits from the very beginning。亲子互动手工可以提high亲子陪伴的质量，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。 Boosting children's self-confidence during 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 learn more scientific knowledge and develop their own hands-on abilities。

Principle application：The elliptical machine in this model is slightly different from that in real life，This model is based on the kinetic energy provided by the rotation of the reduction motor，The kinetic energy is then converted into the reciprocating motion of the foot pedal by the rotation of the crank wheel to simulate the movement of the elliptical machine。

Experimental cognition：Through this experiment，The students learned that electrical energy can be converted into kinetic energy，This will drive the movement of dummies。

Knowledge expansion：The elliptical machine drives the flywheel to rotate by stepping on it with both feet and pushing and pulling it with both arms，At the same time, rely on magnetic force、Frictional force and the inertia of the flywheel form the resistance to motion。

Knowledge extension：Mechanical energy is the sum of kinetic energy and potential energy，The potential energy here is divided into gravitational potential energy and elastic potential energy。We transfer kinetic energy、Gravitational potential energy and elastic potential energy are collectively referred to as mechanical energy。
