Monarch butterfly group 3D animation model

Monarch butterfly group 3D animation model

Monarch butterfly is a large butterfly, belonging to the family Papilionidae. The wings are orange with blackish veins and margins, and a row of small white spots along the edges. This unique color combination makes it very eye-catching when flying. The life cycle includes four stages: egg, larva, pupa and adult. The larvae feed on milkweed, a plant that contains toxins that gives monarch butterflies a certain defense against natural enemies after they become adults. The adults mainly feed on nectar, have strong flight ability and long migration distance. The most famous feature is its large-scale migratory behavior. This migratory behavior is one of the most spectacular phenomena in the insect world.
Snail in vivo structure 3D model

Snail in vivo structure 3D model

The snail is a general term for the terrestrial taxa of the mollusk phylum gastropod, which belongs to invertebrates. The body is soft and usually protected by a spiral hard shell. The head has two pairs of antennae, the longer one for sensing the environment and the shorter one associated with smell and taste. The foot is muscular and moves slowly on various surfaces by secreting mucus. The shell is one of its distinctive features. The shape and color of the shell vary from type to type, from simple conical to complex spiral. It is a protective device for snails, and it can also help them retain moisture and adapt to dry environments. It's an omnivorous animal. It is often used for scientific research, ecological education or as a food.

Winslet Machine Experiment

Winslet Machine Experiment

The Winslet machine is an electrostatic generator invented by James Winslet in the late 19th century. It generates high voltage through two relatively rotating insulating disks and a series of metal brushes and electrodes. In experiments, the Winslet machine can demonstrate electrostatic phenomena such as electric sparks and corona discharges, which are commonly used in teaching and demonstrating the principles of electrostatics.

Oscillator Principle Experiment (3D Experimental Animation)

Oscillator Principle Experiment (3D Experimental Animation)

The LC circuit mainly consists of capacitors and inductors, which oscillate freely through the mutual conversion of electric field energy and magnetic field energy. To maintain oscillation, an amplification circuit with positive feedback is required. LC oscillators are divided into transformer coupled and three-point oscillators. Many quartz crystal oscillators are used, and LC oscillators composed of integrated operational amplifiers are also used. Due to the fact that the parameters of the device cannot be exactly the same, the states of the two transistors change at the moment of power on. This change, due to the increasingly strong positive feedback effect, leads to reaching a temporary steady state.
Joule Meter Principle Experiment (3D Experimental Animation)

Joule Meter Principle Experiment (3D Experimental Animation)

In 1847, Joule designed a more ingenious experiment by placing water in a calorimeter, installing a rotating shaft with blades in the middle, and then letting a descending weight drive the blades to rotate. Due to the friction between the blades and water, both the water and the calorimeter heated up. Based on the height of the heavy object falling, the converted mechanical work can be calculated; Based on the temperature rise of water in the calorimeter, the increase in internal energy of water can be calculated. By comparing two numbers, the accurate value of thermal energy equivalent can be obtained.

Galena

Galena

Galena is a common mineral that is a sulfide with a metal (lead) to sulfur ratio of 1:1. It is the most important ore for lead and also an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. Galena (also known as lead sulfide) is a common mineral and an important ore mineral for extracting lead. It is the most widely distributed lead mineral. Galena is a gray lead sulfide, and China has been extracting lead from galena since before the Shang Dynasty. Galena has a cubic shape, and many of these cubic crystals come together to form granules or blocks.
