CATDOLL : CATDOLL: Snail breeding method lesson plan (snail breeding method lesson plan middle class)

1. How to breed snails?

1. Living environment

First, you need to find a box, preferably a breathable sealed box, and put paper towels on the bottom of the box, preferably odorless paper towels, and then spray it with water, because snails need a humid environment, otherwise they will dry out. In addition, snails do not like sunlight, and the room temperature between 25 and 30 degrees is the most suitable environment for snails.

2. Food

Because snails are omnivores, they like to eat vegetable leaves and fruit slices, but they cannot contain salt because snails are afraid of salt. Generally speaking, you should feed snails three times a day. Before feeding, check whether the paper towel is clean. If it is dirty, you have to replace it with a new wet paper towel before feeding the snail.

3. Winter management

Hibernation can be ended under artificial temperature and humidity control. If the breeding conditions are not met, when the temperature drops to around 15℃, insulation treatment should be carried out according to local conditions. If it is moved indoors, the breeding soil should be thickened to 25 cm and cotton wool should be used for insulation.

Breeding points:

1. Temperature

16～40℃, 25℃ is the best, usually it can be higher but not lower. Heating must be done with ground dragon fire channel, and it should be prepared all year round, especially in late spring and early summer, to prevent sudden temperature drop, it is best to use heating if conditions permit, and do not use stove heating.

2. Humidity

The surface humidity of the breeding soil should be maintained at 25% ~ 35%, and the relative humidity of the air should be 85% ~ 90%. It can be wet but not dry. To control humidity and retain moisture, cover the top with plastic cloth.

3. To prevent dry wind and cold air from blowing in directly, the entrance should have double doors, hanging cloth and wind shield.

4. Resolutely control the entry of odorous gases into the breeding grounds.

5. The pH of the breeding soil must be controlled at 6.5-7.5. Do not use contaminated sandy soil that has been treated with pesticides or chemicals.

6. The breeding container must have good water permeability and air permeability.

2. How to raise snails on trees?

Methods and steps:

1. Feeding box

Snails can be kept in boxes made of glass, plastic or other materials. The best ones are transparent, so that it is easy to observe the snails in the box. The size of the box depends on the size of the snail. Generally speaking, it is best to choose a larger box to allow the snail to have a certain amount of space to move around. The box cannot be sealed, but must have a gap to allow air circulation inside the box.

2. Spread the breeding soil

After choosing a box for snails, you need to spread a layer of sterilized soil in the box. The soil can be some soil dug from the vegetable field and spread on the bottom of the box, with a height of about one-fourth of the box. Because snails like a humid environment, the soil must be kept moist and not too dry. Therefore, according to the dryness of the soil, spray the soil with water.

3. Feeding

Snails are omnivorous animals

Snails like to eat a variety of fruits, vegetables, melons, etc. In daily feeding, you can feed snails with various vegetable leaves, some rotten fruits, wheat flour, etc.

Snails can be fed with a variety of foods such as sesame, white beans, etc. You can feed them in different ways. You don't have to feed them a single food. But be careful that snails are afraid of salt and salty foods, so be sure not to let them eat salt.

4. Breeding environment

Snails are most afraid of direct sunlight and are sensitive to the environment. The most suitable temperature for snails is 16-30℃ (the fastest growth and development is at 23-30℃).

60-90%, the humidity of the breeding soil is about 40%, and the pH is 5-7. When the temperature is below 15℃ and above 33℃, the snails will hibernate. If the temperature is below 5℃ or above 40℃, they may be frozen to death or heat-killed. In winter and other cold weather, snails will enter hibernation.

5. Hygiene and cleaning

Snails like a clean environment, so you should pay attention to the cleanliness of the breeding box. Generally, you should clean it every 3 to 4 days to remove the food residues and snail feces in the box to provide the snail with a clean environment. In addition, you should also put some leaves, branches, etc. in the box for the snails to crawl and play on. But be sure to spray water on the box to keep it moist.

3. Lesson plan for raising snails in the middle class?

Activity objectives:

1. Observe the external characteristics of the snail and understand its living habits and movement methods.

2. Raise snails and learn about the foods they like to eat.

3. Develop the habit of observing small animals.

4. Learn to record your discoveries in various forms such as language and symbols.

5. Develop children's observation and imagination.

Activity preparation:

1. Glass plate, wooden board, wooden stick, magnifying glass.

2. Rice grains, tree leaves, vegetable leaves, and tomatoes.

3. Snails, crabs, and turtles.

Activity process:

1. Introduce the topic in the form of a riddle: It has no feet, no hands, and walks around with its house on its back. If someone touches it, it will quickly hide inside the house.

2. Observe snails

3. Game "Running Race"

4. Feed snails Encourage young children to feed snails with rice grains, tree leaves, vegetable leaves, tomatoes, etc. and observe what they like to eat.

4. How do I raise the snails given by school (I am a sixth-grade student in Pudong District, Shanghai)?

Snails are easy to raise: prepare a container, about 20 cm square, to raise two white jade snails. Spread a layer of wet soil about 4.5 cm thick inside, cover the container with glass or transparent plastic plate to observe the activities of snails. Feed fresh leaves every day. Remove the rotten leaves that have not been eaten. Soon, the snails will lay eggs in the soil, and they will hatch into small snails after about 10 days. The key points of raising are: 1. Keep the soil moist, but not too wet to become a paste; 2. The leaves should be clean and fresh. Soak the leaves in clean water for two or three hours in advance to remove the pesticide residue on the leaves. 3. Don't cover it too tightly, and keep the air circulating. 4. Prevent the snails from escaping. 5. Keep the container clean and remove the residual leaves and snail excrement in time. 6. When the small snails grow up, change to a larger container in time. There are many varieties of snails, among which white jade snails are edible snails with high nutritional value. French baked snails are a famous dish. But don't try to eat ordinary wild snails to avoid poisoning.

5. How to raise small snails?

The little snail is so cute*^o^ How to breed it:

① Preparation: A glass container that is at least three times larger than the snail's body. A thin plastic plate (transparent). Poke a few small holes (for ventilation) and cover the glass container to prevent the snail from escaping. A little water that has just touched the bottom, tap water or boiled water.

②Feeding: Some vegetable leaves, such as water spinach leaves, green vegetable leaves, you can also feed fruits such as watermelon and melon, which should be chopped

③Others: Brush the glass container of the snail frequently to remove feces and mucus. Do not place the snail in the sun, but in a cool and humid place.
