Objectives: 1. By operating activities, perception of objects due to the shift of the center of gravity roll phenomenon occurred. 2. Learn to fill in the experimental record sheet. 3. Cultivation of down-to-earth, meticulous learning attitude and interest in exploring things. Preparation: 1. Test tubes, capsules, steel balls, wood beads, matches head, transparent tube, eggshell, paper mouse, glass ball, “egg intelligence” (see photos), building blocks, tables and so on. 2. Have known “intelligence egg”; will take the slope. Process: 1. Organize the game to stimulate interest. ① Today we play a fun science game together, please children close your eyes first. Well, now you see, what’s in this transparent tube? (IQ egg) ② This “IQ egg” may work! You
