Hello, landlord
I found an animated film "Little Skin World" which is more suitable for your needs.
It mainly contains six scientific themes-object movement, sound, digital measurement, animals and plants, shape, light and color.
It provides the best way for preschool children to understand science and cultivate their curiosity. Parents can also purposefully cultivate their children's scientific literacy through other topics, including "animals", "classification", "home and living environment", "measurement", "numbers", "plants", "properties of objects and materials", "shape and composition", "simple machines", "simple tools", "sound" and ".
